I just want to make the observation that this whole SpaceX IPO is turning out entirely unlike the CDOs that led to the 2008 financial crisis. There's no mixing of AAA level assets with a bunch of subprime stuff and then getting someone to buy it all as AAA. Not at all similar. Completely different. Will turn out just fine this time.
The assets weren’t AAA, you’re mixing it up a bond concepts. The deal had bonds that were AAA. And if you’re talking about CDOs then the assets were bonds which were usually BBB or similarly cuspy bonds.
You should learn about securitizations. It’s actually interesting. But people talk about it colloquially and so incorrectly that it’s mind dumbing.
Here’s a simplified example of how you can take something and turn it into a safe investment:
Suppose you have 10 loans and each has a 50% chance of default. Ignore coupon, and say they are $10 each. Expected value is $50
If you were to put this in a deal and cut it up into tranches, say the first tranche gets the first $10, this would be your AAA bond because odds of getting paid out you $10 would be > 99.9%. The equity (bottom tranches) would pay a lot less. For instance the expected value of the bottom half would be considerably less than $50 that is being promised. So there’s upside since you’ll be paying cents on the dollar and even though in the median scenario you’re making nothing, you have to weight the expected values of each scenario to figure out how to price it.
The problem w this model is that it only works if assets are relatively uncorrelated which wasn’t true (it was true in the past but ignored systematic risk and adverse selection in originations).
What this has to do w musk or spacex I’m still not sure
It is adversely selected, but it's not debt, it's equity, so price action can go real fast and nobody will be burned except folks who soberly-or-not opted into this. Everyone _knows_ Elon is the way he is, so nobody will be _surprised_ at things. No surprise, no crisis.
They're going to force a S&P500 index listing on IPO day so we're all going to be forced to baghold this regardless of if we want to or not unless you've got $0 in any major retirement fund.
If your retirement fund is an IRA you can invest it in any stock you want. For a 401k you probably have some fund options that are not exposed to the S&P500, like emerging markets or fixed income
So far only Nasdaq has changed its rules and will allow fast entry in 15 trading days. S&P has not changed its rules, not yet at least. Total indexed capital of Nasdaq is 1.4T vs 16T in the S&P500. Stated reason for fast tracking is that the indices are supposed to be a broad representation of the market, and leaving a 2T company out would be a significant tracking error.
I do agree that the optics of this aren’t great, and it’s rather easy to be cynical about motives.
I'm not an expert but it looks to my like 80% of my allocation won't be tracking spacex and the 20% that's in the vanguard growth index might? I assume whoever sets the rules for the fund could change the rules to say companies must be listed for X months if they want to avoid this, right?
You gotta do what you think is best, but I hope for future you's sake you decide to not pull the money out. Or if you do you have other retirement plans.
I'm trying to help my parents now their at retirement age and am seeing first hand what not planning for your future looks like. They hit retirement with nothing but a small social security check every month. Not even enough to cover rent in most places.
I don't know how much you have in your 401k, but it will be worth literally hundreds of thousands more if you pull it out when you retire. You aren't just paying the penalties now, you're paying for potentially decades of load compounding.
You could just buy deep out of money SP500 puts expiring in 1+ year. That way you would be "insured" against the bubble popping.
The thing is, every dollar you spend on insurance is a dollar (and its interest) you lose. Furthermore, we don't know when it will pop. 1 year? 5 years?
The more reasonable solution is probably gradually reduce exposure to US markets by selling SP500 shares and turning to Europe and emerging markets ETFs. No need to cash out 401k.
If you just look at the past 20 years, the US has had exceptional returns compared to the rest of the world.
The thing is, historically, high PE ratios like what we're seeing in the US do not correlate with short term returns that are as high. Expected future returns decrease as the PE ratios go up in a pretty linear fashion.
The question is, is everyone integrating a special SpaceX correction in their algorithmic trading? Because if a dip in the index due to SpaceX causes old algorithms to think it’s a more structural issue (well, more than it is), and sell on that indicator, will that cause a cascade?
Friendly reminder that SpaceX is going straight to the index—Elon agitated for it. The 401k of everybody in America is serving as a bailout fund for X and now cursor, and whatever other trash he hovers up
> Nasdaq was the first to consider a rule change that would grant mega IPOs like SpaceX early admission to its flagship Nasdaq-100 index. The exchange and index provider began a consultation period in February to assess the viability of and industry response to a proposed “fast entry” rule. The change was approved on March 30 and will be effective on May 1.
Ug wants to borrow ten of my best sticks in exchange for future options to buy berries from his friend Og. Og has a watertight deal with Oog to invest the sticks in a five year mammoth hunting expedition but Oog first needs berries to exchange for sticks to cover his exposure on berry-puts he’s take out against Urrrg’s remortgaged stick pile.
Well, I said no. Not getting burned that way again!
Well, there are some very important differences. 1) It’s super well known what’s going on with SpaceX. Every investor should know that there’s a lot of good stuff along with some steaming hot garbage. 2) SpaceX isn’t systemic to the economy. If SpaceX and all its subsidiaries shut down and its investors got nothing back, it wouldn’t be that big of a deal.
This type of bundling is just what conglomerates do. Is it a good thing? Not really. Many investors also hate this kind of stuff and avoid investing in these types of companies.
On point #2, they are trying to do that right now. If spacex is fast tracked into the indices, passive investors via index funds will be forced into buying.
Every time Musk does anything these days, it further reveals the shell game he's playing with his companies. This is going to be an Enron type of story eventually. I truly wish I had a choice to pull my tax money out of this particular subsidy.
Enron was absolute peanuts compared to the financial fraud Musk has been executing (with the apparent blessing of the SEC). At its peak Enron had a roughly $70B market cap, TSLA is currently sitting at $1.74T. We can expect similar numbers from the SpaceX IPO.
SpaceX is _not_ profitable by most reasonable measurements of accounting. If you discount rocket depreciation costs and R&D, then yeah its profitable from starlink revenue.
The entire space launch market is about $20B with multiple competitors in 2025. And by the most generous estimates it is going to be $80B by 2035. They can reuse the rockets as much as they like, the company isn’t worth $1.7T.
You’re comparing a publicly traded company where the supply demand economics have established a price to a company whose financials are not public, and is valuing itself at $1.7T and forcing everyone’s 401Ks and pension funds to fund it. Not the same thing.
They are low earth orbit satellites. Generally, the lower the orbit, the faster they decay. You could also argue that this is a benefit in that they gain updated technology with each replacement.
If underwriters think it’s worth $1.7T with a $16B revenue (not profit), they’re doing the same thing as the credit agencies did in 2008 by giving underwater mortgage backed securities a AAA rating.
the ability to mine the moon or asteroid belt seems extremely lucrative, the logistics of transporting materials to earth costs less than shipping them across the ocean, an astounding level of value creation.
It is less about profitability and more about dilution of ownership. He seems to have a pattern of diluting the ownership of his profitable companies by folding in his less profitable/failed companies. You still own a share of a profitable company, but a smaller share, to his benefit.
How much of that profit was due to public subsidies of the sort that he killed for other companies but not for himself during his tenure as a special government employee?
> Their market share of EVs in the US went from 40.9% in Q3 2025 to 58.9% in Q4 2025.
You’re not wrong factually, but it doesn’t mean what you’re suggesting it means. Their share went up because EVs aren’t selling as much anymore. All companies including Tesla are selling fewer EVs. They just have a bigger share of the smaller pie, which isn’t exactly a success when you only sell EVs, but your competitors also sell non EVs.
I'm aware of the reason. Their market share is, nonetheless, up. That's still good for Tesla, their sales remained constant while people stopped buying other EVs.
Edit: Constant is the wrong word. Resilient or consistent is what I was trying to say.
Competitors leaving the market means less competition which is a good thing for Tesla. If the market for EVs returns in the future (if, say, the next administration reimplements the incentives), Tesla will be there to reap the benefits.
Matt Levine writes a bit about this - the Elon Musk Mars Conglomerate. And really if you're investing into e.g. SpaceX you're not investing into SpaceX you're investing into the Elon Musk Mars Conglomerate. And most people seem to want that.
Tesla's the odd one out: it's public but it's still in there, although Musk would probably prefer it to be private too.
Tesla is the free cashflow play that is probably the most important for mars as there is no distilled fermented dinosaur juice on mars, but considerably more by ratio of lithium / oil than the Earth. Our flintstone fire mobiles won’t work so well there, and battery / solar will be important there for everything, including mobility and armies of slave robots.
Mars gets less sunlight on a good day for solar power; the inverse cube law really hits you harder than you'd think. And that's before accounting for the planet wide dust storms that can last for months.
We're probably looking at nuclear fission generators to get started, then converting to geothermal at any appreciable (and maybe fusion, inshallah).
I'm pretty sure Tesla and SpaceX are profitable and generate tens of billions in revenue. Words mean something, saying [thing i don't like] is [bad thing] is pretty lazy. How are any of these companies at all related to Enron? Or are you just anti-conglomerate where you have some parts of the business supporting others (nothing to do w/ Enron and pretty normal, how could all business arms be equally profitable?)
Words do mean something, and you could have taken 5 minutes of research to make a reasonable counterclaim
Tesla has an insane PE ratio because it’s a casino stock (~350x). As a comparison, NVIDIA IS 40x. SpaceX
Is projected to be 300-500x. These are fantasy, completely unrealizable valuations. Similar to Enron, and Enron was over 70x. Enron wasn’t some surprise either.
Typically when PE gets out of whack, market analyzers dig into what is happening because it’s usually chicanery. No longer. Everyone is along for the ride.
PE has literally nothing to do with what Enron did which was accounting fraud + cashflow problems because they actually didnt make any money, in fact they lost tons of money and used future earnings in current reporting
Having a high pe is not fraud. There are even companies that are losing money, and they're still worth something.
When people say something is like enron, they dont mean it has a high PE. Its like saying someone is like Hitler and meaning they are a failed art student
Tesla isn't that profitable, but SpaceX is likely generating boatloads of cash. From what I can tell Starlink alone has a free positive cash flow of about $2 billion. I'm not sure what the launch business is worth, but it's likely a lot given the absence of domestic competition.
I have a suspicion the reason Musk wanted to combine SpaceX and X.ai is the latter gives him losses to write off against all that cash from the former plus a chance for a big AI payoff.
In 2024 Gwynne Shotwell said Starlink had a $600 million positive free cash flow based on $8.2 billion in revenue. Last year revenue estimates from both SpaceX and from outside people adding up new military contracts came out to about $11.8 billion. Their fixed costs haven't gone up much, so the big unknown is development costs for military contracts. I think $2 billion is a reasonable, conservative estimate.
So SpaceX bought a $60B Option on Cursor, plus a bunch of services, for $10B.
If strike date comes and Cursor is in fact worth less than $60B... they can move to acquire it for that price. Or just let it "expire". And if it's worth more, they get a savage good deal. If the services were worth $8B anyway, it's hard to lose.
It seems less crazy to me through this lens. A straight acquisition, today, at $60B would in fact be crazy.
Problem is basically, that if the option works out (Cursor truly has the talent to train a frontier model on SpaceX's infrastructure, and were simply lacking the infra before) the fair price would be way way more than $60B.
OpenAI tried to acquire Windsurf last year for $3B and couldn't.
But they also get a whole bunch of AI Services from Cursor. Other comments have noted that xAI has fallen on bad times (idk one way or the other) so perhaps they were going to spend $5B on getting these services elsewhere, anyway.
SpaceX spending $1B a month on various AI services seems ~plausible
(EDIT - Or maybe it's an IP transfer, or maybe it's over a longer time horizon. Idk but SpaceX clearly expects value from 'our work together' even if they don't exercise.)
$1B per month on AI services does not seem remotely plausible to me... Engineers don't consume that many tokens...
And on the AI development side they're the ones providing compute in the form of a "million H100 equivalent Colossus training supercomputer"... On top of the cash.
Cursor has no AI services, they do not develop their own frontier models. I see no reason to understand why $10bn for Cursor's services is an advantage xAI versus say a $10bn deal with Anthropic, OpenAI or Google.
It's true that Cursor doesn't have their own frontier models, but they are training their own models. They just aren't at frontier level yet. The $60B/$10B deal looks like a bet that this is a capital/GPU constraint rather than a capability one.
Despite their impressive ARR, Cursor faces existential threat from not only BigLabs (Claude Code, Open AI Codex) but also BigTech (AWS Kiro, Google Antigravity, MS VSCode). I am sure the usual suspects would have lined up to purchase Cursor, and the deal from xAI was probably the best of the lot. Marks an end to a remarkable sprint for a 3yo company, and an admirable exit (considering the recent discombobulation of Windsurf's), just as investor money and/or hype is going belly up.
It has shown surprising stickiness. Occupying some middle ground between full adoption and still ~in the code.
I am starting to see some potential in moving back away from pure terminal, a mixed modality with AI. But it is not in the direction of IDE in any traditional sense.
* X will have a total of ~2GW of GPU sometime this year largely not doing much outside of 'grok is this true'
* despite no longer being in vogue with consumer devs Cursor still has a lot of developer data that can assist in building a model
* Cursor have decent enterprise relationships (while for xAI it is ~zero) and that's where the real revenue for llms + agents is
* Cursor are paying retail for tokens and competing against the frontier model co's who are also their suppliers. Not sustainable (hence their in-house composer model).
* Cursor the product covers the gamut from lovable-style prompt-to-app, an IDE, cli and bugbot
* X are using "x bucks" to pay for a potential later acquisition which are arguably overvalued based on the space x IPO hype
Option there to give X a window to make it work, otherwise walk away with a $10B breakup fee for access to it's data
> largely not doing much outside of 'grok is this true'
Hey now, don't forget about it's super important other use, taking innocent photos of people and regenerating them in less clothing and compromising positions.
You've literally got tools like opencode that are MIT licensed. Most of those points X could do on their own or are things that make this attractive for cursor not X.
e.g. Need developer data? Use some of that spare GPU compute, hand out free top end model coding access for a bit and you'll very rapidly have developer data
I've had hundreds of AI-powered vendor tools come across my desk as part of my job, and I have yet to see a single one that uses Grok. I'm also not aware of any publicly announced customers for Grok's enterprise offering. The Grok Enterprise website doesn't list any customers.
I think it also represents a bet that in some sense Cursor's model capabilities are resource limited rather than talent limited. If that's true, $60B will end up being a bargain. If not true, well it's an expensive lesson but that's the nature of things.
I think you're right. Other providers can offer coding subscriptions that use in-house models, and this sets the stage for a Grok coding plan that's built in to Cursor.
$60 billion seems expensive, but it gives them a much better chance at competing in the market than if they started their own harness from scratch.
Absolutely no enterprise - I work in enterprise cloud consulting - absolutely no company would trust Grok with their IP compared to Anthropic or OpenAI with Musk’s reputation on how he runs his businesses.
Anthropic just tolerates the money losing developers who pay $20/$200 for subscriptions.
Yes I think you're right. Reinforcement learning is extremely compute heavy, which cursor doesn't have. And X.ai doesn't have the coding agent data anthropic/OpenAI has, but does have the compute.
However, one thing in AI is that while the usage goes up extremely quickly, it tends to go down just as fast. I know a lot of companies that are in the process of switching from Cursor to Claude Code, so in 6-12 months I'm not entirely sure of the data quality/quantity.
Also I think it is telling that they are calling them SpaceX not X. The X brand is absolutely toxic, especially in enterprise.
> forgot to consider whether all this is worth $60B
I see two possibilities:
(1) SpaceX is paying with stock; and
(2) the $60bn pay-out is (a) conditional or (b) never going to be exercised—it was a stalking horse for negotiating the $10bn terms, which gives SpaceX everything it actually wants.
$1B to $2B ARR in a few months with projection of $6B ARR by years end. If xAi wants to have it's own tools just like OpenAI and Anthropic, then it's not an unusual move.
Anyone saying this is an aquahire has it backwards. SpaceX is acquiring Cursor’s customers, all those enterprises including NVIDIA itself. I believe Jenson Huang is on the record about the engineers using Cursor everyday.
As far as I know, xAI’s enterprise market share is non-existent. This is their way to get some much needed customers.
NVIDIA has 42,000 employees. Even still, when their deal with Cursor comes to an end do we really expect them to stay loyal? And further, sign on with xAI?
When they could instead sign with the new hottest enterprise coding IDE (Claude, Codex, etc who are way more popular now). Maybe if it’s an acquihire, it’s the GTM/Sales that xAI is after?
I guess the hope is that combining two sub-par coding models (xAI's grok + cursor's composer) and combining the data they have access to, they can build something that can compete with OpenAI / Anthropic in the coding space...
I guess I kinda see it... it makes sense from both points of view (xAI needs data + places to run their models, cursor needs to not be reliant on Anthropic/OpenAI).
I think I don't see it working out... I just don't see an Elon company sustaining a culture that leads to a high-quality AI lab, even with the data + compute.
I was required to use Cursor for my job when I first started, but once I figured out how to use the command line version of Codex, I kind of stopped seeing the point. It just kind of seemed like a bloated, overpriced wrapper around what I could do with the included ChatGPT membership I already had for work.
Maybe I was missing something, but I do not understand how it is worth sixty billion dollars.
Lots of people in the comments talking about how this is about training data, but surely this is actually about hiring competent people after the mass exodus/firing at xAI?
Whoever thinks the talent pool is this limited that it requires offering Cursor of all places $60B is pattern-matching so hard they might as well be a quilt.
Guess I'll be looking for a replacement for Cursor now...
Anyone have recommendations? I like the plan/agent mode and the fact that it's an IDE, so I can use it in the traditional way as well as by yapping with a bunch of agents. Also the Cursor rules I've curated and they do their job well.
Consider Nimbalyst, its a free visual workspace for Claude Code and Codex that has visual editing of markdown, mockups, diagrams, code with your agents with WYSYWIG diffs as well as task management and kanban session management tied into your agents. Its got a files/plan/editing mode and an agent/sessions mode.
This is a classic Elon move. He bundled up his company that is, shall we say, crap, into his most valuable company, then tried to hype it up as much as he could. Like when he promised Tesla cars would self drive in X years but it never happened, then pivoted to AI/robots, then re-routed Tesla’s GPUs to xAI, etc.
Cursor might not be the new hotness, but if we believe that agentic coding is the next wave and we’ve gone from asking chatbots to actually using agents for coding, then yes, this move makes sense for Elon to hype up a SpaceX IPO.
You sour pusses are wrong. This is a smart move that amplifies a brilliant team from cursor with serious compute, raising the odds Elon can get to the frontier, which is worth so much these numbers will all look like a drop in the bucket.
Wow, we are seeing the dark underbelly of the beast here. Nobody talks about cursor anymore for a reason. Look, I'm not saying it's not useful and discounting anyone getting value out of it...
But it's clearly not worth 60B dollars in April 2026.
Yep. there's absolutely no way that Cursor is worth that much.
for contrast, Elon paid $44b for twitter back in 2022.
When you adjust for inflation, Twitter was acquired for $49b in 2026 money. Cursor getting bought for 1.22x more is just insanity.
Elon seems unwilling to shake off the image that he has basically no idea what he's doing.

I wouldn't be so sure when "any other country except US" usually apply to everything on the Internet, except Twitter after the power transfer
No. JP activity was always second to US, only the biggest "out there". Same is true for all Twitter-like social media, such as Mastodon and Bluesky. Even VRChat doesn't have a majority Japanese userbase. Japan actually becoming the top majority anywhere is an anomaly and a major reversal of power balance.
This is actually an amazing sweetheart deal for Cursor. Many times with these high profile acquisitions, most stock is tied to LPA's and employment at the company, and also earnout provisions. The company then finds a way to parachute them out early, which both voids the earnout and their employment, thus they never vest most of the units and the few units they do vest get bought out at 409A valuations which are typically much, much lower.
In the case of Cursor this is an amazing boon as SpaceX listed at an almost 100x multiple which is absolutely staggering. Had SpaceX stayed private they could have 409a'd Cursor and got it for effectively ~100M$ cash.
Just because it's not discussed much on HN does not imply it is not relevant in the broader space. Cursor is still very much prevalent there with 1 mil DAU.
I’m curious if that 1 million DAU still holds as of today. I think it was reported last year some time aka before December when Claude code exploded. A quick google didn’t turn up any results that actually contained sources for the number.
You sour pusses are wrong. This is a smart move. Cursor has a brilliant, capable team with serious model chops who will be able to boost the odds of AGI success. They also come with a revenue generating machine.
That's a hefty payday for a model that barely functions! Every time I run out of API credits and get kicked back to Composer 2 I feel like I'm better off just packing up for the rest of the month.
I feel like we're finally at a point where you don't have to constantly argue with and constantly babysit coding models, which makes it even more frustrating when you're suddenly forced to deal with one that ignores your instructions and gets stuck in thinking loops again.
I suspect it's the vast troves of training data rather than any tech that Cursor possesses that SpaceX is after...
Cursor is still the best coding environment and hardness. It's actually not really close. They are so good that they actually made Gemini usable.
The problem is they can't compete with Anthropic and OpenAI because they can't sell Opus and GPT at a discount to subscribers like OpenAI and Anthropic do with their subscriptions.
So they either need to build a competing model or slowly die.
I personally disagree on the first point. Claude code in a terminal with vim is much nicer. I just don’t see the need for the bloat of an IDE when the CLI versions work so damn well now.
> They are so good that they actually made Gemini usable
I think Gemini is best model out there, and it's not Cursor who you should praise. I use it with jetbrains junie. Vastly cheaper than claude, faster, produces better quality code, actually listens to your instructions, more accurate. I'm sure claude code cli has some cli magic that I'm missing out on, but having everything just work in a nice IDE (and llm to actually understand your symbol table) is like magic.
I doubt they're buying it for Composer, I imagine they're buying it for the agent harness. It's arguably the best non-Anthropic agentic coding harness, and you get _all the models_ for one subscription price.
I've subscribed to Jetbrains all product for years. If the agent coding is going to be the next wave. Jetbrains is really behind. Even Microsoft offer better agent coding with VScode and Github copilot cli.
I honestly can’t believe how poorly JetBrains has done. I used to love PyCharm but now it’s so far behind. I still use DataGrip but it is absolute dogshit when it comes to agentic coding.
I was a massive jetbrains fan - still believe it's the best IDE even with it's massive performance issues.
But I just... barely use an IDE anymore. I think I have the lowest possible subscription price for "all products" you can have (at least as an outsider) and I think I'm going to cancel this year. I've been paying for a decade+
I am subscribed to their all you can eat plan and use their Junie coding agent which is included with subscription with some free tokens. I then pay for extra tokens on on-need basis and all works like a charm. So far I pay (well my clients do as I bill separately for that) about $100 a month to cover my current coding needs. All works as a charm. I mostly use their CLion, Webstorm and PyCharm IDE's for development, sometimes other as well. All in all dev experience is excellent and far exceeds that of Cursor I was trying to use for a while.
Not sure what problems people here have with JetBrains offerings
Once you work somewhere that gives you unlimited opus 4.6 and learn how to use it properly, your perspective of what you should be doing day to day shifts.
Honestly unlimited codex with 5.4 high has a similar effect.
SOTA models + harnesses used together is very different than it was 6 months ago. People that have significant software engineering experience can get so much done it's scary.
I have what you call "significant engineering experience", decades of it to be precise and have designed and developed many complex products successfully used in various industries.
I do not need to "shift my perspective" since I do use agents to the degree that I need and it helps help me very much. I am way more productive with them.
Generated code is still not perfect disregarding of any particular model (I have access to all). I have to watch and fix, sometimes by supplying more precise specs, sometimes asking to rewrite piece of code in such and such manner using this and that structures.
I use JetBrain's all you can eat subscription that comes with their Junie coding agent which includes some free tokens to cover my coding needs. I then top up tokens on on-need basis. Costs me about $100 / month in AI tokens (well I bill my clients for that separately so do not really care bout the price). All works as a charm. I mostly use their CLion, Webstorm and PyCharm IDE's for development, sometimes other as well. All in all dev experience is excellent and far exceeds that of Cursor I was trying to use for a while.
Not sure what problems people here have with JetBrains offerings
I use both (not IntelliJ but other IDEs) and quite frankly I fund VS Code and derivatives very much inferior. For C++ development for example CLion vs VS Code (needed plugins installed) is night and day and not to the benefit of VS Code.
I know JetBrain product could be sluggish on "normal" computers however all 4 of my development machines run on 16 cores AMD with 128GB RAM. It flies in environments like that
Unless you do Jakarta EE development, where Cursor with their simple LSP support is far, far behind. Cool for generating a bean, but when you got to debugging deployment descriptors you wish you were in IntelliJ.
Is Composer 2 a bad model because Cursor are bad at training models, or because they are compute constrained? This deal will provide the answer to that question.
Cursor is great. I was using it up until recently. Then I switched oh my pi, and honestly I haven't looked back. I've also heard great things about open code.
I actually really like Composer 2. For my use case, between the planning tool, and getting it to ask a lot of clarifying questions, I regularly get very good results. I'm not doing anything complex though; mostly staying in the lane of very common web app type code.
I don’t think this is the case. With “accidentally” collecting an individual’s data, the company’s risk is that somebody cares enough to sue them based on vague and poorly defined damages. With “accidentally” collecting source code, you’ve not only violated your contract with 98% of your enterprise customers (many of which have dedicated legal departments) providing a very real and obvious path to lawsuits, you’ve also gained a strong reputation as a vendor never to be trusted. My employer uses cursor, and I strongly suspect we would cut ties and blacklist them at the first sign of them inappropriately retaining data.
@dang does nothing, he is unlikely to see it. If you actually want to reach the mods, email them. There's a Contact link at the bottom of almost every page here on HN.
EDIT: Parent commenter edited out the @dang from their comment making mine appear to be responding to something not in their comment.
Rockets, satellites, social media, AI - the only thing missing from the SpaceX hype portfolio is a certain coworking company. That would really set them up for an exciting IPO.
I'm sworn off from Musk-related products, and this will prob make cursor worse (switch to X's LLM for instance). So, any suggestions for switching? Codex; Claude Code? (I like my IDE and I like the freedom to choose a model, which is why I stuck with Cursor even when it felt more expensive)
I have no idea what this has to do with aerospace, but I know a bit about software and this does not look great. Cursor is obviously on a serious decline and has little to no moat in the area they are building in (IDE), which we kinda now know is maybe not even the right area (CLI). I feel like this is just a bad move?
SpaceX is just going to be the Musk Company minus Tesla. X Corp, the X parent, is a subsidiary of xAI which is a subsidiary of SpaceX. This seems back to front, but I suppose SpaceX has the better reputation for investors whereas if X owned SpaceX the IPO would be devalued by the association with Twitter.
AFAIK cursor is basically the only player right now not subsidizing tokens out the ass, and has been seeing solid growth across individual and enterprise with almost every model performing best in their harness. Not sure how that’s a serious decline.
On the contrary, anecdotally, myself and every engineer I know have switched fully from cursor to claude code since the start of the year. I now use zed with cc. I personally could not stand the buggy mess and constant UI changes of cursor. It’s also not good value in terms of claude tokens compared to claude code.
Claude/chatGPT are not subsidizing tokens via the API and are profitable for most enterprise consumption. This meme that they lose money on every query has zero evidence and is wrong outside of the 20/200$ a month plans.
Decent analogy in 2nd sentence BUT the 1st doesn't hold water. TIMTOWTDI, statements about "everyone" or "no one" are highly suspect, and the trend of code-assist -> agentic -> delegated / orchestration is just that (a trend), not a universal law. Even in a full-on maximalist yolo paperclip future, many experts will likely ALWAYS want access to a decent IDE. (Note I'm not saying Cursor is necessarily that IDE, and I'm not commenting on the valuation.)
I would like to know where you’re seeing this, because my strong impression is exactly the opposite: a year ago, everyone was talking about Cursor, but I haven’t heard anything about it in months. It’s all Claude Code and Codex now. In terms of mindshare they seem dead already.
wait a few months, been using claude code since beta, there are issues but it takes time to realise what they are. people who have been using claude since 2024 began moving away before Anthropic's marketing blitz at the end of last year.
Cursor's token utilization is significantly better than Claude Code. Composer's latest model, for coding, is very competitive on quality given price and was clearly well-optmiized (in two months, you will hear almost nothing else than how expensive Anthropic is...this is before they try to release the really expensive models). so many very obvious things like this if you have been using this tech every day for multiple years.
unfortunately, the competition in this space is very weak because of how dominant cursor has been (Kilo/Roo/Cline all have major implementation issues with token utilization, everyone else is trying to go all in on agentic). don't see this getting better until things get much worse because of anthropic/agentic. from the decisions that anthropic is making, it seems they are busily digging their own grave. growth will come after this.
Isn’t it obvious? Musk bailed out his Twitter investors with xAI. Then he bailed out xAI with SpaceX. Now he realizes that no one thinks xAI is worth the hundreds of billions he claimed it was in that potentially fraudulent transaction, and is trying to make Grok and xAI relevant by getting access to customers in the AI coding space. But in the end, it’s SpaceX share holders who are being made fools of and soon, especially with the Nasdaq fast track changes to incorporate SpaceX forcefully into everyone’s passive investments, the public will be the one who is made poorer. But Musk will become a trillionaire.
ai trends seem to mirror general coding/software trends but compressed. People used to edit programs with sed, but the ide proved to be more powerful from every perspective. cli tools always have their place for "power-users" and other specialized intermediate usecases like tui's, but in general the ide has overtaken every aspect of cli use and many devs hardly ever use the terminal.
I suspect a similar thing will happen with ai.
SpaceX is no longer SpaceX per se, but SpaceX-xAI.
My TL; DR (and this is mine, personally) is its mission has pivoted from colonising Mars to building a Dyson sphere. Space-based datacentres are a demand excuse for putting lots of solar panels in space. Going one level down, more Cursor use is a demand excuse for putting lots of datacentres anywhere.
And in handstanding walk because you're better at hands than legs. All their advantages are in domains to be obsoleted by technologies required for such things.
Be it the Dyson shell thing or Lunar or Mars colonies, there's no way it'll be done relying on transports from Earth surface. It could only work if we could make them from asteroid pieces. Which makes most items on their tech tree from Starship forward obsolete. And they're already all-in on those techs. It makes so little sense in so many levels.
If we're talking Dyson spheres, this is like going from a half-marathon to running the distance from Earth to Betelgeuse. It's just not a realistic endeavor.
It's a mission, not a business plan. Colonising Mars was always a moonshot as well. But it aligned the company's priorities.
My point is regardless of what you think of a Dyson sphere, this theory seems to predict what the company does better than assuming everything's a ketamine fever dream.
> this theory seems to predict what the company does better than assuming everything's a ketamine fever dream.
I think Musk being a ketamine addict explains a lot and this is very aligned. Given that he can't build a self-driving car, he would have to be under the influence of very strong drugs to think he could build a Dyson sphere of all things.
That being said, some sort of financial fraud is even more on brand.
this is Elon's desperate move to fix his weak coding problem. He recently stated he feels he is far behind in agentic coding, and that apparently that's what matters.
> He recently stated he feels he is far behind in agentic coding, and that apparently that's what matters
Sure. My question was why. And my loose interrogation of the question, together with some unique domain expertise, suggests he found an excuse to work towards a Dyson sphere.
This is the right partnership to happen. SpaceX has all the compute but is missing the talent for training LLMs, especially on the RL side. Cursor has the talent and RL stack, but doesn't have their own pretrained base model or own their compute. Both will be on a bad trajectory without cooperating because Claude Code and Codex have gained so much momentum already.
Snowflake bought streamlit (a python frontend that’s not even better than gradio, it’s main competitor) for 800 million in 2022. We are nowhere near mt stupid. ZIRP was the peak of mt stupid.
This feels like another Twitter moment... unless he's absolutely desperate for engineers who can train LLMs. In that case it's basically an acquihire. Otherwise, this makes absolutely zero sense.
same. i finally tried Claude Code and i just shrugged. Cursor definitely has a clunky UI with an identity crisis, but it pioneered plan mode, and auto / composer chugs along without rate limits for the most part.
What's Cursor's moat here? I'm a bit surprised that xAI/SpaceX needs to buy them rather than building their own VScode forked IDE or an agentic UI/CLI.
I guess it makes more sense than shoe brands pivoting to GPU provider.
Spacex already owns Twitter and xai, trying to post-rationalize with justification like they have servers doesn't make a whole lot of sense. It's all accounting at this point.
For a successful IPO and attract more capital you need a very good story/narrative. That what is being crafted here. Business fundamentals matter less with elon!
Elon doesn't know what to do. Ani failed, no one apart from his alt accounts is interested in Grok pictures.
Since the firing of several Grok founders, Grok has decreased in capabilities. It is illogical and insults users when called out.
So he does what everyone does. Write more dev tools, slap a price on it and hope retail investors will be impressed in the IPO. The $60 billion is of course optional and will just be used in the IPO to inflate the valuation.
I am part of a discord group with about 1000+ devs.
I polled them in Jan to see if they had dropped cursor for claude code.
80% of those responded (250ish in the group had). Bit of selection bias there from the question - but my impression was Cursor is very much dying to competition from the labs.
It looks like this is just an "option" to acquire Cursor at that price? Implying they only plan to exercise the option under certain conditions (such as, one might presume, Cursor actually being worth that much. As right now it definitely isn't.)
Wish I played that interview game better. I saw the success coming from a mile away (2022) but I can't vibe with people in the hire game right. It's like eye contact, smiling, facial expressions, stuff like that.
I guess there's a bunch of tools to not suck at this. Anyone had success here? The AI tools say I'm great because they can't pick up the kind of problems I'm talking about.
Pretend to and/or be motivated by things other than money, that’s the strongest thing interviewers drop people from, even though they’re motivated by money to be there.
my only gripe rn is grok is still a shitty model to use. yeh it scores nearby openai and anthropic on benchmarks, but my personal experience has been underwhelming
I’m no fan of Elon Musk, but even from a neutral perspective I’m bewildered by the merger between X, X.ai, and SpaceX and now this acquisition of Cursor. What’s the endgame? How does this help with the whole vision of “we all live in space and mine resources from the Moon and have data centers on Mars”?
The endgame is to game the index funds by bribing or otherwise.. convincing the big stock exchanges to forgo their index inclusion rules so SpaceX will get included in Nasdaq 100 within 10 days or something stupid like that. SpaceX will initially float a tiny fraction of shares at a wildly inflated value and use a combination of artificial scarcity and Elon Stans (retail) to keep the stock from crashing until it gets included in the indexes. Then, your 401k will auto-buy SpaceX, letting insiders exit at their ludicrous valuation.
Eventually, stock prices will correct hard, and retail/passive investors will be left with the bag.
The idea that merging these companies has some business purpose is hilarious. It’s purely financial engineering. Unfortunately, our existing system has little consumer protection against this kind of fraud, so Elon will probably get away with it, at least in the short term
It gives them some amount of paying customer base using AI. That is some magic voodoo you need to sprinkle onto the public sale to get the highest possible price point.
The Elon Musk Company does what Elon Musk wants. Tesla is dying, X is a disaster, so he bundled everything into the one company that had a bright future, SpaceX. There is no grand vision or endgame beyond do as Elon Musk wants. Going to Mars or the Moon or whatever was never a vision or mission, just a story to tell.
> What’s the endgame? How does this help with the whole vision of “we all live in space and mine resources from the Moon and have data centers on Mars”?
I put this in the other thread, but my personal working hypothesis is the SpaceX/Musk mission has pivoted from colonising Mars to building a Dyson sphere.
Space-based datacenters are a demand excuse for putting solar panels (and eventually, solar-panel fabrication) in space. Cursor is a demand excuse for building more datacenters (and eventaully, learning to fabricate chips). If I'm correct, the next acquisition will be in some chip or solar-panel fabrication bottleneck.
To be clear, I'm not advocating for this mission. (Though I do think the space-based datacenter pitch has gotten more scepticism than it deserves. For realistic interest-rate and terrestrial-delay values, assuming ongoing AI demand, it breaks even for surprisingly-proximate radiator-mass values. Obviously more problems beyond my toy model to solve. But I expected the math to say fuck you out the gate.)
I'm saying this is a good working theory for explaining–and predicting–Musk and SpaceX's actions. Mars explains why SpaceX's engines burn methane. Dyson sphere explains why xAI is building massive datacenters and now finding acquisition targets to fill them with.
So they are trying to take everyone’s money in bigger and bigger chunks until there is no economy left but hype.
Folks, if we spent 1/10th of the time and money we spend on this bullshit on taking care of people’s basic needs and education we would be far closer to the sci-fi future everyone seems so motivated to get to. Covid and the Trump cult seem to have broken almost everyone’s brains and we’re all gonna pay for the hubris.
I don’t doubt it is. End of the day, it’s a fine tuned Kimi. They tried to hide it and making their work sound more impressive than it is. It’s easy to have stuff be cheap when you don’t have to train your own model from scratch.
I am so actually beyond sad that I ever trusted Musk, all the signs were there, from the lies with Tesla to the nonesensical point to point "tourist" lies, to the Mars lies, to the fact that the spaceship they are developing right now requires an actual elevator to get astronauts down, it was never meant for humans, it was meant to deploy sats in space even cheaper, outcompete the competition and basically kill human spaceflight as a result... because less profitable human rated spacecraft won't be viable.
Oh yeah, did I mention how Starlink is literally already in the close to Kessler Syndrome territory? all it would need is for a strong enough solar storm to hit their sats.
"SpaceXAI and
@cursor_ai
are now working closely together to create the world’s best coding and knowledge work AI.
The combination of Cursor’s leading product and distribution to expert software engineers with SpaceX’s million H100 equivalent Colossus training supercomputer will allow us to build the world’s most useful models.
Cursor has also given SpaceX the right to acquire Cursor later this year for $60 billion or pay $10 billion for our work together."
Personally, I have been granted the option to buy Tesla for $30 trillion by the end of this year or pay $500 billion for a partnership. It'll all happen, I swear.
Government subsidized purchase of a private company. Fantastic. All funded by the taxpayer to send rockets to a dead planet and to burn up all the energy on our alive but suffering planet.
Point to any government subsidies for SpaceX - or do you think your salary is a subsidy and everything you do at work is worthless to your employer?
SpaceX has paid for contracts to deliver services to the government and those services have saved the government billions of dollars compared to the alternative.
I really don't know what Elon is thinking here because SpaceX's IPO is already precarious, for several reasons:
1. It was used to rescue himself and key investors from overpaying for Twitter, which was first rescued through xAI (and I don't know why anyone thought investing in xAI was a good idea but here we are). If our regulators weren't defanged, this deal would've gotten alot more scrutiny (IMHO). Whatever the case, this is all diluting the SpaceX business for overpriced AI vaporware;
2. From what I can find, SpaceX's revenue in 2025 was ~$18B with a $5B loss. That doesn't sound like a $1.5T+ company to me;
3. The markets are being rigged to make the IPO a success by changing the rules to force passive funds to buy into it with a tiny float (5% instead of the normal 25%); and
4. Here's the big one. I think Starship is a badly designed program that's going to take many billions more to complete and commercialize. There's not really a market for bigger payloads (evidence: ~1 Falcony Heavy launch per year) and STarship will effectively have to compete with Falcon 9 at a time when reusable alternatives (eg from the Chinese as well as Blue Origin) are coming to market.
Starship won’t compete with F9, or BO because it is fully reusable and cost less than either. The Chinese are not a player in the global launch services market at all so don’t count.
Starship isn’t comparable to Falcon Heavy because it has vastly more volume, which will make it the cheapest way to launch Starlinks, which will be a lot of launches to begin with.
There is a lot resting on Starlink, 11 gigadollars in direct revenue that accounts for fully 60% of SpaceX's total revenue of 18 gigadollars. It's hard to see how that level of revenue can sustain a 1 terradollar valuation.
Like, TSLA had 94 gigadollars in revenue last year, and it's a 1.2 terradollar company, and most outside analysts are frankly skeptical of that multiple. SpaceX is trying to get a similar valuation on a fifth of that revenue.
If this is an acquihire, it doesn't compute for me (though I can't say I understand how things work in the world of the 60B level). LLMs are new enough that nobody has a big enough headstart to warrant a 60B personnel change.
The IPO angle also doesn't make sense. Musk cultists were gonna buy anyway; this doesn't change that. And for everyone else, who wants to pay down debt on an acquisition whose effect will almost certainly not be palpable in mainstream circles, if at all?
I don't fully understand the influence that comes with SpaceX subsidies and government contracts, but I gotta believe that rounding up non-lab AI chops are on that agenda?
The exact options - 60B for acquisition (obviously not a cash deal, right?) or 10B for unspecified services rendered... also don't make sense for either of the first two.
Is this just a way of the government securing contractors by proxy that wouldn't pass muster if done through the normal channels?
You should learn about securitizations. It’s actually interesting. But people talk about it colloquially and so incorrectly that it’s mind dumbing.
Here’s a simplified example of how you can take something and turn it into a safe investment:
Suppose you have 10 loans and each has a 50% chance of default. Ignore coupon, and say they are $10 each. Expected value is $50
If you were to put this in a deal and cut it up into tranches, say the first tranche gets the first $10, this would be your AAA bond because odds of getting paid out you $10 would be > 99.9%. The equity (bottom tranches) would pay a lot less. For instance the expected value of the bottom half would be considerably less than $50 that is being promised. So there’s upside since you’ll be paying cents on the dollar and even though in the median scenario you’re making nothing, you have to weight the expected values of each scenario to figure out how to price it.
The problem w this model is that it only works if assets are relatively uncorrelated which wasn’t true (it was true in the past but ignored systematic risk and adverse selection in originations).
What this has to do w musk or spacex I’m still not sure
I think you meant "the chances of getting paid", not of not getting paid.
I do agree that the optics of this aren’t great, and it’s rather easy to be cynical about motives.
I'm not an expert but it looks to my like 80% of my allocation won't be tracking spacex and the 20% that's in the vanguard growth index might? I assume whoever sets the rules for the fund could change the rules to say companies must be listed for X months if they want to avoid this, right?
And I can change my allocation.
I'm trying to help my parents now their at retirement age and am seeing first hand what not planning for your future looks like. They hit retirement with nothing but a small social security check every month. Not even enough to cover rent in most places.
I don't know how much you have in your 401k, but it will be worth literally hundreds of thousands more if you pull it out when you retire. You aren't just paying the penalties now, you're paying for potentially decades of load compounding.
The thing is, every dollar you spend on insurance is a dollar (and its interest) you lose. Furthermore, we don't know when it will pop. 1 year? 5 years?
The more reasonable solution is probably gradually reduce exposure to US markets by selling SP500 shares and turning to Europe and emerging markets ETFs. No need to cash out 401k.
If you just look at the past 20 years, the US has had exceptional returns compared to the rest of the world.
The thing is, historically, high PE ratios like what we're seeing in the US do not correlate with short term returns that are as high. Expected future returns decrease as the PE ratios go up in a pretty linear fashion.

Well, I said no. Not getting burned that way again!
This type of bundling is just what conglomerates do. Is it a good thing? Not really. Many investors also hate this kind of stuff and avoid investing in these types of companies.
I don’t personally think Google is worth $4T but the share price says otherwise.
Source?
That’s just money in the door and the underwriters seem to think the business is worth $1.75T.
Did you notice the size of the Artemis rocket and the size of the payload it sends to the moon and back?
Do you expect there to be diamonds just laying these on the moon surface, no mining required.
You may not have noticed because positive Musk related news doesn't seem to make headlines anymore.
You’re not wrong factually, but it doesn’t mean what you’re suggesting it means. Their share went up because EVs aren’t selling as much anymore. All companies including Tesla are selling fewer EVs. They just have a bigger share of the smaller pie, which isn’t exactly a success when you only sell EVs, but your competitors also sell non EVs.
Edit: Constant is the wrong word. Resilient or consistent is what I was trying to say.
Competitors leaving the market means less competition which is a good thing for Tesla. If the market for EVs returns in the future (if, say, the next administration reimplements the incentives), Tesla will be there to reap the benefits.
Their sales did not remain constant.
Tesla's the odd one out: it's public but it's still in there, although Musk would probably prefer it to be private too.
That’s SpaceX’s version of Tesla’s self driving car pipe dream
Edit - I use self-driving car and Autopilot interchangeably
We're probably looking at nuclear fission generators to get started, then converting to geothermal at any appreciable (and maybe fusion, inshallah).
Tesla has an insane PE ratio because it’s a casino stock (~350x). As a comparison, NVIDIA IS 40x. SpaceX Is projected to be 300-500x. These are fantasy, completely unrealizable valuations. Similar to Enron, and Enron was over 70x. Enron wasn’t some surprise either.
Typically when PE gets out of whack, market analyzers dig into what is happening because it’s usually chicanery. No longer. Everyone is along for the ride.
When people say something is like enron, they dont mean it has a high PE. Its like saying someone is like Hitler and meaning they are a failed art student
There's a lot of parallels:
* Circular transactions between companies under the same control
* Using SPVs to keep debt off the books
* The supplier funding its own customer through investment to inflate revenue on both ends
* Valuations driven by a hyped up narrative and decoupled from actual fundamentals
I have a suspicion the reason Musk wanted to combine SpaceX and X.ai is the latter gives him losses to write off against all that cash from the former plus a chance for a big AI payoff.
They're prepping for an IPO and there have been some anonymous insider reports of the figures in the press
There are industry estimates
Much of their income comes from public contracts
If strike date comes and Cursor is in fact worth less than $60B... they can move to acquire it for that price. Or just let it "expire". And if it's worth more, they get a savage good deal. If the services were worth $8B anyway, it's hard to lose.
It seems less crazy to me through this lens. A straight acquisition, today, at $60B would in fact be crazy.
OpenAI tried to acquire Windsurf last year for $3B and couldn't.
SpaceX spending $1B a month on various AI services seems ~plausible
(EDIT - Or maybe it's an IP transfer, or maybe it's over a longer time horizon. Idk but SpaceX clearly expects value from 'our work together' even if they don't exercise.)
And on the AI development side they're the ones providing compute in the form of a "million H100 equivalent Colossus training supercomputer"... On top of the cash.
But I agree that it's hard to articulate what Cursor services you could blow this much money on.
Maybe it is all just an option! Or maybe they get a bunch of IP either way?
I didn't say it was Wise.
I said it seems within possibility for this, very particular, corporation.
I am starting to see some potential in moving back away from pure terminal, a mixed modality with AI. But it is not in the direction of IDE in any traditional sense.
* X will have a total of ~2GW of GPU sometime this year largely not doing much outside of 'grok is this true'
* despite no longer being in vogue with consumer devs Cursor still has a lot of developer data that can assist in building a model
* Cursor have decent enterprise relationships (while for xAI it is ~zero) and that's where the real revenue for llms + agents is
* Cursor are paying retail for tokens and competing against the frontier model co's who are also their suppliers. Not sustainable (hence their in-house composer model).
* Cursor the product covers the gamut from lovable-style prompt-to-app, an IDE, cli and bugbot
* X are using "x bucks" to pay for a potential later acquisition which are arguably overvalued based on the space x IPO hype
Option there to give X a window to make it work, otherwise walk away with a $10B breakup fee for access to it's data
Hey now, don't forget about it's super important other use, taking innocent photos of people and regenerating them in less clothing and compromising positions.
I'm sad that I even know that.
e.g. Need developer data? Use some of that spare GPU compute, hand out free top end model coding access for a bit and you'll very rapidly have developer data
>decent enterprise relationships
I guess. 60B worth of "relationships" though?
They tried this - grok was free on openrouter for a while
I’m curious where you pull these stats from
$60 billion seems expensive, but it gives them a much better chance at competing in the market than if they started their own harness from scratch.
Anthropic just tolerates the money losing developers who pay $20/$200 for subscriptions.
However, one thing in AI is that while the usage goes up extremely quickly, it tends to go down just as fast. I know a lot of companies that are in the process of switching from Cursor to Claude Code, so in 6-12 months I'm not entirely sure of the data quality/quantity.
Also I think it is telling that they are calling them SpaceX not X. The X brand is absolutely toxic, especially in enterprise.
Is it in vogue with enterprise devs?
I see two possibilities:
(1) SpaceX is paying with stock; and
(2) the $60bn pay-out is (a) conditional or (b) never going to be exercised—it was a stalking horse for negotiating the $10bn terms, which gives SpaceX everything it actually wants.
“Cursor have” and “Cursor are” is awkward to read.
As far as I know, xAI’s enterprise market share is non-existent. This is their way to get some much needed customers.
When they could instead sign with the new hottest enterprise coding IDE (Claude, Codex, etc who are way more popular now). Maybe if it’s an acquihire, it’s the GTM/Sales that xAI is after?
I guess I kinda see it... it makes sense from both points of view (xAI needs data + places to run their models, cursor needs to not be reliant on Anthropic/OpenAI).
I think I don't see it working out... I just don't see an Elon company sustaining a culture that leads to a high-quality AI lab, even with the data + compute.
Steal their Twitter usernames anyway, just like he did mine.

(If any lawyers read this and feel up for taking this on contingency, I don't think I'm difficult to contact.)
Maybe I was missing something, but I do not understand how it is worth sixty billion dollars.
They’re buying the customers and the brand.
Anyone have recommendations? I like the plan/agent mode and the fact that it's an IDE, so I can use it in the traditional way as well as by yapping with a bunch of agents. Also the Cursor rules I've curated and they do their job well.
Cursor might not be the new hotness, but if we believe that agentic coding is the next wave and we’ve gone from asking chatbots to actually using agents for coding, then yes, this move makes sense for Elon to hype up a SpaceX IPO.
But it's clearly not worth 60B dollars in April 2026.
for contrast, Elon paid $44b for twitter back in 2022. When you adjust for inflation, Twitter was acquired for $49b in 2026 money. Cursor getting bought for 1.22x more is just insanity.
Elon seems unwilling to shake off the image that he has basically no idea what he's doing.

More accurately it is 3.4% of SpaceX at the last rumored valuation of $1.75T.
This is actually an amazing sweetheart deal for Cursor. Many times with these high profile acquisitions, most stock is tied to LPA's and employment at the company, and also earnout provisions. The company then finds a way to parachute them out early, which both voids the earnout and their employment, thus they never vest most of the units and the few units they do vest get bought out at 409A valuations which are typically much, much lower.
In the case of Cursor this is an amazing boon as SpaceX listed at an almost 100x multiple which is absolutely staggering. Had SpaceX stayed private they could have 409a'd Cursor and got it for effectively ~100M$ cash.
Not just OpenAI, but OpenAI and OpenAI[1].

I feel like we're finally at a point where you don't have to constantly argue with and constantly babysit coding models, which makes it even more frustrating when you're suddenly forced to deal with one that ignores your instructions and gets stuck in thinking loops again.
I suspect it's the vast troves of training data rather than any tech that Cursor possesses that SpaceX is after...
The problem is they can't compete with Anthropic and OpenAI because they can't sell Opus and GPT at a discount to subscribers like OpenAI and Anthropic do with their subscriptions.
So they either need to build a competing model or slowly die.
Cursor is essentially all the Claude Code products but without the horrible bugs of Claude Code products.
You can transfer from CLI to web and it actually works.
I think Gemini is best model out there, and it's not Cursor who you should praise. I use it with jetbrains junie. Vastly cheaper than claude, faster, produces better quality code, actually listens to your instructions, more accurate. I'm sure claude code cli has some cli magic that I'm missing out on, but having everything just work in a nice IDE (and llm to actually understand your symbol table) is like magic.
A controlled environment to determine effort and token usage, and to get plenty of exclusive training on code.
It could end up making sense. Idk if they needed to offer 60B though.
But I just... barely use an IDE anymore. I think I have the lowest possible subscription price for "all products" you can have (at least as an outsider) and I think I'm going to cancel this year. I've been paying for a decade+
Not sure what problems people here have with JetBrains offerings
Honestly unlimited codex with 5.4 high has a similar effect.
SOTA models + harnesses used together is very different than it was 6 months ago. People that have significant software engineering experience can get so much done it's scary.
I do not need to "shift my perspective" since I do use agents to the degree that I need and it helps help me very much. I am way more productive with them.
Generated code is still not perfect disregarding of any particular model (I have access to all). I have to watch and fix, sometimes by supplying more precise specs, sometimes asking to rewrite piece of code in such and such manner using this and that structures.
Not sure what problems people here have with JetBrains offerings
I know JetBrain product could be sluggish on "normal" computers however all 4 of my development machines run on 16 cores AMD with 128GB RAM. It flies in environments like that
EDIT: Parent commenter edited out the @dang from their comment making mine appear to be responding to something not in their comment.
I have no idea what this has to do with aerospace, but I know a bit about software and this does not look great. Cursor is obviously on a serious decline and has little to no moat in the area they are building in (IDE), which we kinda now know is maybe not even the right area (CLI). I feel like this is just a bad move?
A team could build an AI IDE in a week, this could be a race to the bottom
Cursor's token utilization is significantly better than Claude Code. Composer's latest model, for coding, is very competitive on quality given price and was clearly well-optmiized (in two months, you will hear almost nothing else than how expensive Anthropic is...this is before they try to release the really expensive models). so many very obvious things like this if you have been using this tech every day for multiple years.
unfortunately, the competition in this space is very weak because of how dominant cursor has been (Kilo/Roo/Cline all have major implementation issues with token utilization, everyone else is trying to go all in on agentic). don't see this getting better until things get much worse because of anthropic/agentic. from the decisions that anthropic is making, it seems they are busily digging their own grave. growth will come after this.
SpaceX is no longer SpaceX per se, but SpaceX-xAI.
My TL; DR (and this is mine, personally) is its mission has pivoted from colonising Mars to building a Dyson sphere. Space-based datacentres are a demand excuse for putting lots of solar panels in space. Going one level down, more Cursor use is a demand excuse for putting lots of datacentres anywhere.
Be it the Dyson shell thing or Lunar or Mars colonies, there's no way it'll be done relying on transports from Earth surface. It could only work if we could make them from asteroid pieces. Which makes most items on their tech tree from Starship forward obsolete. And they're already all-in on those techs. It makes so little sense in so many levels.
My point is regardless of what you think of a Dyson sphere, this theory seems to predict what the company does better than assuming everything's a ketamine fever dream.
I think Musk being a ketamine addict explains a lot and this is very aligned. Given that he can't build a self-driving car, he would have to be under the influence of very strong drugs to think he could build a Dyson sphere of all things.
That being said, some sort of financial fraud is even more on brand.

Sure. My question was why. And my loose interrogation of the question, together with some unique domain expertise, suggests he found an excuse to work towards a Dyson sphere.
That already happened with xAI-X merged with SpaceX.
The “apply” model to turn LLM output into code changes?
I like SpaceX a lot but this really doesn’t make sense at $60B
Opus, I watch my allotment creep up every turn…
Spacex already owns Twitter and xai, trying to post-rationalize with justification like they have servers doesn't make a whole lot of sense. It's all accounting at this point.
Though, in fairness, that's probably the important part. Like a base model plus "coding smarts" is probably perfect for the situation.
But maybe not as much value as I was thinking.
2. Make SpaceX valuation even higher before IPO
3. Boost XAI/usage of Grok.
Since the firing of several Grok founders, Grok has decreased in capabilities. It is illogical and insults users when called out.
So he does what everyone does. Write more dev tools, slap a price on it and hope retail investors will be impressed in the IPO. The $60 billion is of course optional and will just be used in the IPO to inflate the valuation.
80% of those responded (250ish in the group had). Bit of selection bias there from the question - but my impression was Cursor is very much dying to competition from the labs.
I guess there's a bunch of tools to not suck at this. Anyone had success here? The AI tools say I'm great because they can't pick up the kind of problems I'm talking about.
The motivation of money is literally zero to me. Maybe that's a problem as well: they want people who Are motivated by money acting like they aren't?
I wanted in because I saw them doing exciting impactful things That's literally it.
I dunno. I've been struggling with this for decades

This could be a lot of money to spend to acquire users that may not be sticky.
This seems like an elaborate Elon rug pull. A Windsurf situation 2.0
Eventually, stock prices will correct hard, and retail/passive investors will be left with the bag.
The idea that merging these companies has some business purpose is hilarious. It’s purely financial engineering. Unfortunately, our existing system has little consumer protection against this kind of fraud, so Elon will probably get away with it, at least in the short term
Buying Cursor does nothing for this.
I put this in the other thread, but my personal working hypothesis is the SpaceX/Musk mission has pivoted from colonising Mars to building a Dyson sphere.
Space-based datacenters are a demand excuse for putting solar panels (and eventually, solar-panel fabrication) in space. Cursor is a demand excuse for building more datacenters (and eventaully, learning to fabricate chips). If I'm correct, the next acquisition will be in some chip or solar-panel fabrication bottleneck.
To be clear, I'm not advocating for this mission. (Though I do think the space-based datacenter pitch has gotten more scepticism than it deserves. For realistic interest-rate and terrestrial-delay values, assuming ongoing AI demand, it breaks even for surprisingly-proximate radiator-mass values. Obviously more problems beyond my toy model to solve. But I expected the math to say fuck you out the gate.)
I'm saying this is a good working theory for explaining–and predicting–Musk and SpaceX's actions. Mars explains why SpaceX's engines burn methane. Dyson sphere explains why xAI is building massive datacenters and now finding acquisition targets to fill them with.
So they are trying to take everyone’s money in bigger and bigger chunks until there is no economy left but hype.
Folks, if we spent 1/10th of the time and money we spend on this bullshit on taking care of people’s basic needs and education we would be far closer to the sci-fi future everyone seems so motivated to get to. Covid and the Trump cult seem to have broken almost everyone’s brains and we’re all gonna pay for the hubris.
DM me if you want an invite. I am keeping it to a small on purpose.
Oh yeah, did I mention how Starlink is literally already in the close to Kessler Syndrome territory? all it would need is for a strong enough solar storm to hit their sats.
these are weird times...

The combination of Cursor’s leading product and distribution to expert software engineers with SpaceX’s million H100 equivalent Colossus training supercomputer will allow us to build the world’s most useful models.
Cursor has also given SpaceX the right to acquire Cursor later this year for $60 billion or pay $10 billion for our work together."

Personally, I have been granted the option to buy Tesla for $30 trillion by the end of this year or pay $500 billion for a partnership. It'll all happen, I swear.
SpaceX has paid for contracts to deliver services to the government and those services have saved the government billions of dollars compared to the alternative.
> those services have saved the government billions of dollars compared to the alternative
Source? All I can find is some guy saying it.
And it doesn't really matter what they've saved. It doesn't excuse conflicts of interest.
shows how intense the power laws are around ai and how much of a capital game it is.
1. It was used to rescue himself and key investors from overpaying for Twitter, which was first rescued through xAI (and I don't know why anyone thought investing in xAI was a good idea but here we are). If our regulators weren't defanged, this deal would've gotten alot more scrutiny (IMHO). Whatever the case, this is all diluting the SpaceX business for overpriced AI vaporware;
2. From what I can find, SpaceX's revenue in 2025 was ~$18B with a $5B loss. That doesn't sound like a $1.5T+ company to me;
3. The markets are being rigged to make the IPO a success by changing the rules to force passive funds to buy into it with a tiny float (5% instead of the normal 25%); and
4. Here's the big one. I think Starship is a badly designed program that's going to take many billions more to complete and commercialize. There's not really a market for bigger payloads (evidence: ~1 Falcony Heavy launch per year) and STarship will effectively have to compete with Falcon 9 at a time when reusable alternatives (eg from the Chinese as well as Blue Origin) are coming to market.
Starship isn’t comparable to Falcon Heavy because it has vastly more volume, which will make it the cheapest way to launch Starlinks, which will be a lot of launches to begin with.
Like, TSLA had 94 gigadollars in revenue last year, and it's a 1.2 terradollar company, and most outside analysts are frankly skeptical of that multiple. SpaceX is trying to get a similar valuation on a fifth of that revenue.
If this is an acquihire, it doesn't compute for me (though I can't say I understand how things work in the world of the 60B level). LLMs are new enough that nobody has a big enough headstart to warrant a 60B personnel change.
The IPO angle also doesn't make sense. Musk cultists were gonna buy anyway; this doesn't change that. And for everyone else, who wants to pay down debt on an acquisition whose effect will almost certainly not be palpable in mainstream circles, if at all?
I don't fully understand the influence that comes with SpaceX subsidies and government contracts, but I gotta believe that rounding up non-lab AI chops are on that agenda?
The exact options - 60B for acquisition (obviously not a cash deal, right?) or 10B for unspecified services rendered... also don't make sense for either of the first two.
Is this just a way of the government securing contractors by proxy that wouldn't pass muster if done through the normal channels?
I guess back to Jetbrains it is.
"Please estimate Elon's IQ based on his timeline"
It estimated 115-130. A decision like this points to the lower end.
