TL;DR
SpaceX exercised its option to buy Anysphere, the maker of Cursor, in a $60 billion all-stock deal announced June 16. The acquisition gives SpaceX a major AI coding app and developer base, but it does not settle whether Grok can compete with stronger frontier models.
SpaceX has exercised its option to acquire Anysphere, maker of the AI coding agent Cursor, in a $60 billion all-stock deal announced June 16, adding a major software application to an AI operation that already includes power, compute, xAI research and Grok models.
Confirmed: the transaction is structured as an all-stock acquisition, with Cursor shares converting into SpaceX Class A shares, according to the source material citing SpaceX filings. The deal is expected to close in the third quarter of 2026, after which Cursor would become a wholly owned SpaceX subsidiary.
SpaceX had earlier secured an option to buy Cursor for $60 billion or pay a $10 billion alternative fee tied to the companies’ work together. Cursor CEO Michael Truell framed the deal as a joint effort to build “the world’s most useful AI models,” with a co-trained model planned for Cursor and Grok Build.
Cursor is valuable because it is one of the rare AI applications with large paying business demand. The source material says Cursor reached about $4 billion in annualized revenue by early June, up from about $2 billion in February. It also says Cursor had rebuffed prior interest from OpenAI and Microsoft, and that its newest model used tens of thousands of xAI chips before the acquisition move.
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.

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 SpaceX is moving from AI infrastructure ownership into a paid developer product with distribution, customer relationships and direct feedback from software teams. That gives SpaceX more than compute capacity; it gives the company a channel where AI models are tested against daily engineering work.
The acquisition also sharpens the central question around SpaceX’s AI strategy. Owning power supply, data centers, GPUs, a research lab and an application does not prove that Grok is a leading foundation model. The source material describes Grok as the weak layer, arguing that SpaceX bought the application layer it had not built on its own.
For developers and enterprise customers, the deal could affect which models Cursor favors, how product data is governed and whether pricing or product bundling changes after the close. Those details have not been fully disclosed.

Colossus Built The Compute Base
SpaceX’s AI push rests on the Colossus supercomputing buildout in Memphis. The source material says the first 100,000-GPU cluster was built in 122 days, then doubled to 200,000 GPUs in 92 more. It places the broader Memphis site at about 555,000 Nvidia GPUs and roughly 2 gigawatts of power capacity.
The same material says SpaceX built on-site gas generation faster than utility interconnection could meet demand and has filed plans tied to orbital data-center ambitions. Those assets make SpaceX one of the few companies positioned to provide compute at very large scale.
Yet the infrastructure story is mixed. According to SpaceX filings cited in the source material, Anthropic and Google have lease arrangements for Colossus capacity worth a combined roughly $26 billion a year. A reported internal xAI memo put Colossus 1 utilization at about 11% and called that level “embarrassingly low,” after Grok training moved to Colossus 2.

Grok’s Gap Is Unresolved
It is not yet clear whether the Cursor acquisition will make Grok more competitive against models from OpenAI, Anthropic or Google. The source material says Grok has underdelivered relative to the scale of SpaceX’s compute, but independent benchmark gains from the planned co-trained model have not been shown.
Several deal details are also still developing: regulatory review, closing conditions, post-close leadership structure, customer data rules, product pricing and how Cursor will work with non-Grok models. SpaceX has the assets to attempt deeper vertical control, but the market test will be product quality, developer retention and model performance.

Q3 Close And Model Test
The next milestone is the expected third-quarter closing. After that, attention will move to the planned co-trained model for Cursor and Grok Build, any changes to Cursor’s model menu and pricing, and whether enterprise customers remain comfortable under SpaceX ownership.
Investors will also watch whether SpaceX can turn Colossus leases into steady revenue while improving Grok. If the model layer remains behind rivals, the Cursor deal may strengthen SpaceX’s distribution without solving the hardest technical problem in its AI stack.

Key Questions
What did SpaceX buy?
SpaceX agreed to buy Anysphere, the company behind the AI coding agent Cursor, in a $60 billion all-stock deal expected to close in Q3 2026.
Why is Cursor valuable to SpaceX?
Cursor brings a paid developer product, a large user base, enterprise demand and an engineering team focused on AI coding. The source material says Cursor had reached about $4 billion in annualized revenue by early June.
Does this mean Grok has caught its rivals?
No. The acquisition gives SpaceX more control over distribution and product feedback, but it does not by itself prove Grok has matched OpenAI, Anthropic or Google models.
What could change for Cursor users?
Cursor is expected to become a wholly owned SpaceX subsidiary, and a co-trained model is planned for Cursor and Grok Build. Specific changes to pricing, model access and data policies have not been fully disclosed.
Why are Anthropic and Google part of the story?
The source material says SpaceX is leasing Colossus compute capacity to Anthropic and Google, showing that SpaceX’s infrastructure can generate revenue even while Grok’s competitive standing remains unsettled.
