TL;DR
SpaceX exercised an option on June 16 to buy Anysphere, the maker of Cursor, for $60 billion in an all-stock deal, according to the provided source material citing filings and reports. The deal would add a revenue-generating AI coding app to SpaceX’s compute, power, research, model and distribution assets, while leaving open whether Grok can compete at the foundation-model layer.
SpaceX exercised its option on June 16 to buy Anysphere, the maker of the AI coding agent Cursor, for $60 billion in an all-stock deal, according to the provided source material citing company filings and media reports, adding a fast-growing developer app to its AI infrastructure, model and distribution holdings.
The deal calls for each Cursor share to convert into SpaceX Class A shares and is expected to close in the third quarter of 2026, according to the source material. SpaceX had previously secured the right to buy Anysphere for $60 billion or pay a $10 billion alternative fee; it has now chosen the acquisition path.
Anysphere was founded in 2022 by four MIT graduates and built Cursor into one of the best-known AI coding products. The source material says Cursor reached about $4 billion in annualized revenue by early June, up from about $2 billion in February. Those figures are reported historical metrics, not forecasts or investment guidance.
The acquisition would place Cursor alongside SpaceX-linked AI assets that the source material describes as spanning power, compute, research, models and distribution. The same material says Cursor’s newest model was trained on tens of thousands of xAI chips and that two senior Cursor engineers had already moved to xAI before the deal.
SpaceX owns every layer
of AI now
The $60B Cursor buy completes the stack: power, compute, research, model, app, distribution. But owning every layer isn’t winning every layer — and the model is the weak one.
(Anysphere)
You can buy a coding app and a model team. You can’t buy the research lead that makes your foundation model the one everyone else builds on — which is why Anthropic pays Musk $1.25B/month, not the other way around. Owning every layer bought SpaceX the right to attempt the hard thing. It hasn’t done it yet.
Cursor Gives SpaceX Paying Users
The deal matters because Cursor gives SpaceX a commercial AI application with paying developer customers, not just infrastructure or research capacity. In the current AI market, coding tools are among the clearer areas where businesses have shown willingness to pay for AI software.
That changes the shape of SpaceX’s AI position. The company is described in the source material as controlling power generation, large GPU clusters, xAI’s research operation, the Grok model line, and distribution through X, Tesla, Optimus and now Cursor’s developer base. The acquisition would give SpaceX a direct route from its compute resources to a widely used software product.
The harder question is whether that structure improves Grok enough to compete with stronger foundation models. The source material’s central reading is that SpaceX has bought the application layer it lacked, while the model layer remains the weaker point. That is analysis, not a confirmed outcome.

How SpaceX Built The Stack
The source material says xAI was folded into SpaceX in February 2026, bringing the Grok model line and research team under the same corporate structure as SpaceX’s compute buildout. It also points to the Colossus supercomputer complex in Memphis as the strongest layer in the company’s AI position.
According to the provided material, the first 100,000-GPU Colossus cluster went from bare factory floor to training in 122 days and later doubled to 200,000 GPUs in 92 more days. The Memphis site is described as having about 555,000 Nvidia GPUs across H100, H200 and GB200 systems, with roughly 2 gigawatts of total power capacity.
The source material also says Colossus 1 was partly leased to outside AI companies after xAI moved Grok training to Colossus 2. It cites lease figures of $1.25 billion per month from Anthropic through May 2029 and $920 million per month from Google through June 2029, for roughly $26 billion a year in compute revenue. Those amounts are attributed to SpaceX filings as summarized in the provided source.

Grok Still Faces The Test
It is not yet clear whether owning Cursor will materially improve Grok’s standing against rival models from OpenAI, Anthropic, Google and others. The source material argues that Grok has underdelivered relative to SpaceX’s compute position, but that is an analytical judgment rather than a confirmed benchmark result in the material provided.
Several deal details also remain developing, including regulatory review, employee retention, product integration plans, pricing changes, and how Cursor’s existing customers will respond after the acquisition closes. The source material says a co-trained model is expected to ship into Cursor and Grok Build soon, but it does not give a firm release date.
The reported lease figures, utilization claim and revenue numbers are attributed to filings, reports and an internal memo cited by the source material. They should be read as source-attributed figures unless confirmed in the underlying documents.

Q3 Close And Model Test
The next milestone is the expected closing of the Anysphere acquisition in the third quarter of 2026. If completed, Cursor would become a wholly owned SpaceX subsidiary, according to the source material.
After that, attention will move to product execution: whether Cursor’s team can ship the planned co-trained model into Cursor and Grok Build, whether developers keep using the product under SpaceX ownership, and whether Grok shows measurable gains. The acquisition gives SpaceX a stronger distribution channel, but the model layer still has to prove itself in use.

Key Questions
What did SpaceX buy?
SpaceX exercised an option to acquire Anysphere, the company behind the AI coding agent Cursor, in a $60 billion all-stock deal, according to the provided source material.
When is the deal expected to close?
The source material says the transaction is expected to close in the third quarter of 2026, after which Cursor would become a wholly owned SpaceX subsidiary.
Why is Cursor valuable to SpaceX?
Cursor gives SpaceX a revenue-generating AI application and a developer distribution channel. The source material says Cursor reached about $4 billion in annualized revenue by early June 2026.
Does this mean SpaceX leads AI?
Not necessarily. The deal strengthens SpaceX’s vertical position across infrastructure, software and distribution, but the source material argues that Grok’s model performance remains the weak point.
What remains unconfirmed?
It is still unclear how regulators will view the deal, how Cursor will change under SpaceX ownership, and whether the planned co-trained model will improve Grok enough to change its competitive position.
