TL;DR
SpaceX exercised its option to buy Anysphere, maker of Cursor, for a reported $60 billion in all-stock, according to source material citing company filings and media reports. The deal would give SpaceX a major AI coding app, but questions remain over whether Grok can match the strength of its compute and distribution.
SpaceX exercised an option on June 16 to buy Anysphere, maker of the AI coding agent Cursor, for a reported $60 billion in all-stock, a deal that would give the newly public company control of a profitable AI application layer while leaving its Grok model as the main open question in its AI strategy.
The transaction would convert each Cursor share into SpaceX Class A shares and is expected to close in the third quarter of 2026, according to the source material, which cites SpaceX filings and reporting from outlets including Reuters, The Wall Street Journal, TechCrunch and Forbes. SpaceX had earlier secured the option to buy Cursor for $60 billion or pay a $10 billion alternative fee.
Cursor, founded in 2022 by four MIT graduates, had reached roughly $4 billion in annualized revenue by early June, up from about $2 billion in February, according to the same source material. That makes the company one of the few AI software businesses with large, recurring customer spending, especially among developers using AI coding tools.
The deal follows earlier signs of tighter ties between Cursor and xAI. Cursor’s newest model was trained on tens of thousands of xAI chips, and two senior Cursor engineers had already moved to xAI, according to the source material. Cursor had also rebuffed approaches from OpenAI and interest from Microsoft, according to the same account.
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 Fills SpaceX’s App Gap
The acquisition matters because it would give SpaceX a direct foothold in a paid AI use case where customers already show a willingness to spend: software development. Infrastructure owners can earn money by renting compute, but owning a widely used application gives SpaceX access to workflow data, developer relationships and a product channel for future models.
The source material frames the deal as the final missing layer in SpaceX’s AI stack: power, compute, research, model, application and distribution. SpaceX already controls major compute assets through the Colossus clusters in Memphis, xAI’s Grok model line, and consumer or industrial distribution through X, Tesla and Optimus. Cursor adds a business-facing developer product with revenue already in place.
The main risk is that vertical control does not by itself prove model leadership. The source material argues that Grok remains the weak layer because rivals are renting SpaceX compute while building models that may still be more attractive to enterprise customers. That judgment is an interpretation, not a confirmed technical ranking, but it is central to why the deal is being watched closely.

Colossus Powers the Strategy
SpaceX’s AI push is built around large-scale compute. The source material says the first 100,000-GPU Colossus cluster in Memphis went from bare factory floor to training in 122 days, then doubled to 200,000 GPUs in another 92 days. The broader Memphis site is described as running about 555,000 Nvidia GPUs across H100, H200 and GB200 systems, with roughly 2 gigawatts of power capacity.
The same source material says the initial Colossus phase cost as much as $4 billion, while silicon across the expanded site has been pegged near $18 billion. SpaceX also built on-site gas generation, a move presented as a way to bypass slow utility interconnection timelines that can limit AI data center growth.
SpaceX has also positioned Colossus as a revenue source. According to the source material, xAI moved Grok training to Colossus 2 after struggling to parallelize training on a mixed H100, H200 and GB200 build at Colossus 1. SpaceX then leased Colossus 1 capacity to Anthropic through May 2029 at a reported $1.25 billion per month and to Google through June 2029 at a reported $920 million per month, for about $26 billion a year in combined compute revenue.

Grok’s Lead Is Unproven
It is not yet clear whether the SpaceX-Cursor combination will produce a model that can compete with leading systems from OpenAI, Anthropic or Google. The source material says a co-trained model will ship into Cursor and Grok Build soon, but no benchmark results, enterprise adoption data or independent testing have been cited in the provided material.
Several deal details also remain dependent on filings and cited reports rather than direct public statements in the source text. Those include the final closing conditions, integration plan, governance of Cursor as a wholly owned subsidiary, and whether Cursor’s existing customers will see product, pricing or data-use changes after the acquisition closes.

Q3 Close and Model Trial
The next milestone is the expected close of the Cursor acquisition in the third quarter of 2026. After that, investors, developers and AI customers will be watching whether Cursor keeps growing, whether its product remains attractive under SpaceX ownership, and whether the promised co-trained model improves day-to-day coding performance.
The larger test is whether SpaceX can turn ownership of power, compute, research, models, apps and distribution into model leadership. For now, the confirmed development is the reported Cursor acquisition. The open issue is whether Grok becomes the model others build on, or whether SpaceX remains a powerful infrastructure owner serving rivals that lead at the model layer.

Key Questions
What did SpaceX buy?
SpaceX exercised an option to buy Anysphere, the company behind Cursor, for a reported $60 billion in all-stock, according to the source material.
Why is Cursor valuable to SpaceX?
Cursor gives SpaceX a revenue-generating AI application used by developers, plus a distribution channel for models tied to Grok and xAI compute.
What remains uncertain about the deal?
The closing conditions, integration plan, customer impact and performance of the planned co-trained model are still not fully clear from the available source material.
Why is Grok described as the weak layer?
The source material argues that SpaceX has built or bought strong power, compute and application assets, while Grok has not yet shown that it can outperform rival frontier models.
When is the deal expected to close?
The acquisition is expected to close in the third quarter of 2026, according to the source material.
