TL;DR
SpaceX exercised its option on June 16, 2026, to buy Anysphere, maker of Cursor, for $60 billion in stock, according to public reports. The deal gives SpaceX an application layer for its AI buildout, but the central test remains whether Grok can compete at the model layer rather than mainly supply compute to rivals.
SpaceX exercised its option on June 16, 2026, to buy Anysphere, the company behind the AI coding agent Cursor, for $60 billion in an all-stock deal, adding a high-revenue developer application to a company already controlling major AI compute, power, research, model and distribution assets. The acquisition matters because it tests whether owning the AI stack can fix SpaceX’s reported weakness at the foundation-model layer: Grok.
The transaction converts each Cursor share into SpaceX Class A shares, with closing expected in Q3 2026 and Cursor set to become a wholly owned subsidiary, according to reported deal terms. The Guardian and Investor’s Business Daily reported the $60 billion price and the expected closing window after SpaceX’s market debut.
Cursor CEO Michael Truell framed the combination as a joint effort to build “the world’s most useful AI models,” and the company has said a co-trained model will ship into Cursor and Grok Build soon. No release date, benchmark data or customer migration plan has been made public.
Cursor brings SpaceX a paid AI application at a moment when many AI businesses are still proving demand. The reported figures put Cursor at roughly $4 billion in annualized revenue by early June, up from about $2 billion in February. That makes the deal less about buying a code editor alone and more about acquiring developer distribution, enterprise revenue and a model team that can be tied directly to SpaceX compute.
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 Paid Demand
The deal gives SpaceX a fuller AI business loop: power generation, Nvidia GPU clusters, xAI research, Grok, Cursor and distribution through X, Tesla, Optimus and developer users. If the integration works, Cursor demand can run on SpaceX infrastructure while Grok gains a direct route into daily coding workflows.
The risk is that infrastructure control does not automatically create the best model. If Grok remains behind rival coding and reasoning systems, SpaceX could earn large sums renting compute to competitors while other companies capture more value from model performance and software adoption.

The xAI Deal Set This Up
SpaceX folded xAI into its business in February 2026, according to Reuters and other reports, bringing Grok under the same corporate roof as Starlink, X-linked distribution and the Colossus compute buildout in Memphis. The Cursor option followed in April: SpaceX could buy Anysphere for $60 billion later in the year or pay a $10 billion alternative fee for the work with Cursor.
The source account says the Memphis site includes about 555,000 Nvidia GPUs across Colossus 1 and 2 and roughly 2 gigawatts of total power capacity. It also says SpaceX has filed plans for orbital data-center satellites, but those plans remain a regulatory and engineering proposal, not an operating system.

Grok Is Still Unproven
It is not yet clear whether Cursor’s team and SpaceX’s compute will make Grok more competitive in coding. SpaceX has not published audited product-level results showing that Grok has closed the gap with leading coding models.
The reported utilization figure and lease economics come from filings and a reported internal memo; they point to pressure inside the compute strategy but do not, by themselves, prove model quality. It is also not yet clear how Cursor customers will respond if the product roadmap becomes tied more closely to SpaceXAI.

Q3 Close And Model Release
The next milestones are deal approvals, the expected Q3 2026 close and the promised co-trained model for Cursor and Grok Build. Investors, developers and AI customers will be watching Cursor retention, pricing, data terms and public model results. SpaceX’s reported compute leases with Anthropic and Google will also show whether the company earns more from renting infrastructure than from its own AI software in the near term.

Key Questions
Did SpaceX buy Cursor?
SpaceX exercised an option to acquire Anysphere, Cursor’s maker, for $60 billion in stock. The deal is expected to close in Q3 2026, so it is not final until closing conditions are met.
Why is Cursor valuable to SpaceX?
Cursor brings paying developers, enterprise customers and a fast-growing coding workflow. That gives SpaceX a commercial AI application to connect with its compute and Grok model work.
Does this mean SpaceX has won in AI?
No. The deal gives SpaceX more control across power, compute, research, model, application and distribution, but model performance remains the open test. Owning infrastructure is different from having the model developers choose first.
What is the weak link in the stack?
The weak link described in the source account is Grok, SpaceX’s foundation model. Reports cited in the account say Grok training moved to Colossus 2 while Colossus 1 capacity was leased to outside AI companies.
Who is renting SpaceX compute?
The source account cites lease figures for Anthropic through May 2029 and Google through June 2029. Those reported rentals would make SpaceX a major AI compute supplier even as it tries to improve its own model business.
