SpaceX Secures $60B Option to Acquire Cursor

What did SpaceX announce about Cursor?

SpaceX has secured the right to acquire AI coding startup Cursor for $60 billion later in 2026, or pay $10 billion for their joint work together. The aerospace company disclosed the arrangement in a post on X. Cursor is built by San Francisco-based Anysphere.

The structure is a call option, not a straight acquisition. SpaceX pays $10 billion to Cursor regardless of outcome. If SpaceX exercises the option, it pays an additional $50 billion. If it walks away, Cursor keeps the $10 billion and its independence.

The deal came together fast. It preempted a $2 billion fundraise Cursor was days away from closing at a $50 billion valuation. Prospective investors were caught off guard, according to Monday Momentum's reporting on the deal structure.

What is Cursor, and how big is it?

Cursor is an AI-powered coding tool built on a fork of Visual Studio Code. It competes with GitHub Copilot, Anthropic's Claude Code, and OpenAI's Codex. Cursor's parent company, Anysphere, is headquartered in San Francisco.

Cursor's growth has been rapid. The company hit $500 million in annualized revenue in June 2025, crossed $1 billion by November 2025, and reached $2 billion by February 2026. It is forecasting more than $6 billion in annualized revenue by the end of 2026.

Cursor says more than half of the Fortune 500 use its product. Named customers include Nvidia, Salesforce, Uber, Stripe, and PwC.

What is the Colossus supercomputer?

SpaceX's Colossus is described as having the equivalent compute of one million Nvidia H100 chips. The deal pairs Cursor's product with that infrastructure. Cursor said in its blog post that it has "been bottlenecked by compute" and that the partnership will let its team "dramatically scale up the intelligence of our models," as InfoWorld reported.

SpaceX's post on X stated: "The combination of Cursor's leading product and distribution to expert software engineers with SpaceX's million H100 equivalent Colossus training supercomputer will allow us to build the world's most useful models."

What has Cursor built on its own models?

Cursor released Composer less than six months before the announcement as its first agentic coding model. Composer 1.5 scaled reinforcement learning by more than 20 times. Composer 2 reached frontier-level performance at a fraction of the cost of other models, according to Cursor's blog post.

Cursor co-founder and CEO Michael Truell said he was "excited to partner with the SpaceX team to scale up Composer," calling the arrangement "a meaningful step on our path to build the best place to code with AI."

Gartner principal analyst Nitish Tyagi flagged one constraint: "Composer is fine-tuned on the Chinese base model Kimi 2.5, making it unsuitable for organizations with restrictive governance policies."

Why did SpaceX pursue this deal?

SpaceX merged with xAI in February in a deal valued at $1.25 trillion. That merger brought Musk's AI lab, the Grok chatbot, and the X social platform under the rocket company. SpaceX is targeting a June IPO at a valuation of $1.75 trillion to $2 trillion, with an IPO filing claiming a total addressable market of $28.5 trillion.

Here's what we know so far: SpaceX is delaying the potential acquisition until after that IPO. Acquiring a $60 billion company before a public listing would require updating financial filings and would complicate the roadshow. After the IPO, SpaceX can finance the purchase using publicly traded stock.

Microsoft looked at buying Cursor before the SpaceX deal and chose not to proceed. Microsoft already owns GitHub Copilot, which has 4.7 million paying subscribers, up 75% year over year.

What does this mean for enterprise Cursor customers?

Cursor's enterprise contracts include a commitment to no training on customer data by Cursor or the LLM providers it routes to. Deepika Giri, AVP and head of AI research at IDC Asia/Pacific, said that exposure is the immediate concern.

"Cursor's existing zero-data-retention agreements with model providers like OpenAI and Anthropic could be challenged under the new SpaceX ownership," Giri said. She added that "Cursor will cease to maintain model neutrality, which will work in favor of xAI."

Giri recommended that CIOs "consider demanding change-of-control clauses with 90 to 180-day notice on any subprocessor or model routing changes."

Tyagi pointed to a recent precedent: Anthropic restricted Windsurf's model access amid OpenAI acquisition rumors. He said the SpaceX deal "could backfire for Cursor if major providers like OpenAI or Anthropic limit model access."

Cursor currently relies heavily on Claude as its underlying model. Anthropic and OpenAI both supply frontier models that Cursor resells through its IDE — and both have launched competing coding tools of their own. Builders tracking AI workforce shifts at major tech companies will recognize this pattern of vertical pressure on tooling providers.

Tyagi also said "key uncertainties remain — specifically whether the roadmap will prioritize Grok, Composer, both, or an entirely new model."

Cursor's parent, Anysphere, agreed to acquire code review startup Graphite in December, adding pull request and debugging capabilities to its enterprise stack. Developers watching how AI coding tools are reshaping developer workflows will want to track how this partnership evolves.

SpaceX and Cursor did not immediately respond to requests for comment. The option is structured to close after SpaceX's June IPO.
