TL;DR
SpaceX exercised its option to buy Anysphere, the maker of Cursor, for $60 billion in stock, according to the provided source material and recent reports. The deal gives SpaceX a profitable AI coding app and developer channel, but whether Grok can match rivals remains unproven.
SpaceX exercised its option to buy Anysphere, the maker of the AI coding tool Cursor, for $60 billion in stock, adding a major paid software product to its AI business days after its IPO pushed the company above a $2 trillion valuation.
The deal is structured as an all-stock transaction, with Cursor shares converting into SpaceX Class A shares, according to the provided source material. It is expected to close in the third quarter of 2026, after which Cursor would become a wholly owned SpaceX subsidiary. Investor’s Business Daily and The Guardian also reported the $60 billion all-stock acquisition.
Cursor CEO Michael Truell described the tie-up 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 had reached roughly $4 billion in annualized revenue by early June, according to the source material, making it one of the few AI applications already producing large recurring software revenue.
The confirmed development is the acquisition agreement and its basic structure. The broader claim that SpaceX now owns every major layer of the AI stack is an interpretation based on its control of power, data centers, xAI research, Grok, Cursor, and distribution through X, Tesla, Optimus, and Cursor’s developer base.
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 it moves SpaceX beyond infrastructure and model development into a paid AI application with enterprise demand. Coding tools have become one of the clearest business cases for generative AI, and Cursor gives SpaceX direct access to developers, usage data, and revenue that Grok has not yet matched on its own.
It also changes the competitive map. OpenAI, Anthropic, Google, Microsoft, and Amazon each control parts of the AI stack, but SpaceX is now closer to a vertically integrated AI company: power generation, large GPU clusters, research staff, a foundation model, an application layer, and distribution. That position could reduce its reliance on outside platforms and increase pressure on rivals that rent compute or lack a high-growth AI app.
The deal does not prove that Grok has caught up. The source material frames Grok as the weak layer: SpaceX can buy an application and supply compute, but model quality still depends on research execution, training efficiency, and developer trust.

Colossus Built the Opening
SpaceX’s AI push accelerated after xAI was folded into SpaceX in February 2026, according to the source material. The company has since tied Grok, its research team, and massive compute projects more closely to SpaceX’s balance sheet and infrastructure plans.
The strongest layer appears to be compute. The source material says SpaceX’s Memphis Colossus site includes roughly 555,000 Nvidia GPUs across Colossus 1 and 2, with about 2 gigawatts of power capacity planned or available. It says the first 100,000-GPU cluster was built in 122 days and later expanded, with silicon costs for the broader site pegged near $18 billion.
The source material also says SpaceX shifted Grok training to Colossus 2 after xAI struggled to parallelize training on a mixed H100, H200, and GB200 build at Colossus 1. That account is attributed to reporting and a reported internal xAI memo, not a public benchmark release from SpaceX. SpaceX filings cited in the source material say Colossus 1 capacity has been leased to Anthropic through May 2029 at $1.25 billion per month and to Google through June 2029 at $920 million per month, implying about $26 billion a year in compute revenue.

Grok Still Faces Its Test
It is not yet clear how regulators, customers, or Cursor employees will respond before closing. It is also unknown how tightly Cursor will be tied to Grok, whether existing Cursor customers will accept deeper SpaceX integration, and whether the promised co-trained model will outperform alternatives from OpenAI, Anthropic, Google, or other coding-tool providers.
The reported Colossus utilization issue has not been independently confirmed in public filings cited here. The broader claim that Grok is SpaceX’s weak layer is analysis based on reported training issues and market comparisons, not a finding from a new public benchmark released with the acquisition.

Q3 Close and Model Proof
The next milestone is the expected Q3 2026 closing. After that, investors and developers will be watching whether SpaceX ships the co-trained Cursor-Grok model on schedule, keeps Cursor’s growth intact, and turns its compute advantage into better software. The key proof will be adoption, revenue retention, model performance, and whether outside companies continue paying SpaceX for infrastructure while competing with its AI products.

Key Questions
What did SpaceX buy?
SpaceX agreed to buy Anysphere, the company behind Cursor, in a $60 billion all-stock deal. Cursor is an AI coding tool used by developers and businesses.
Why does Cursor matter to SpaceX?
Cursor gives SpaceX a paid AI application, a developer user base, and a team focused on coding models. That adds a commercial software layer to SpaceX’s compute and model work.
Does this mean Grok is now ahead?
No. The deal gives Grok more resources and a strong application partner, but model leadership still has to be proven through performance, reliability, and customer adoption.
How does Colossus fit into the deal?
Colossus is SpaceX’s large GPU infrastructure in Memphis. The source material says Cursor had already trained newer model work on xAI chips, making the acquisition a tighter link between Cursor software and SpaceX compute.
What is still unconfirmed?
The final closing, regulatory path, employee retention, customer reaction, and performance of the planned co-trained model are still developing. Reported internal utilization figures also remain based on source accounts rather than a full public disclosure.
