SpaceX has formally agreed to buy Cursor, the AI coding assistant, for $60 billion in stock. The deal was announced Tuesday morning, just days after SpaceX completed the largest initial public offering in history, raising $75 billion and listing on the Nasdaq at $135 per share. By Tuesday, the stock had already climbed past $200.
Cursor is a tool that sits inside a developer's computer and helps them write, fix, and review software code. It does not just suggest the next line: it can read an entire codebase and rewrite large sections on its own, following plain-language instructions. Nvidia's CEO called it his favourite enterprise product, and Nvidia reportedly put all 40,000 of its engineers on it. The tool is used at Stripe, OpenAI, and Datadog, and Cursor's own website says it is trusted by 64% of Fortune 500 companies.
The financial trajectory is striking. Cursor went from $100 million in annual revenue in January 2025 to $2 billion by February 2026, making it the fastest software company in history to reach that milestone. At the time the deal was first signalled in April, Cursor was planning to raise another $2 billion from investors including Andreessen Horowitz and Nvidia, at a valuation of $50 billion. SpaceX offered $60 billion and a $10 billion breakup fee if the deal fell through, and Cursor accepted.
The context behind the purchase is harder to ignore than the numbers. SpaceX's AI division was built around xAI, the company Musk founded in 2023 to compete with OpenAI and Anthropic. All 11 of xAI's original co-founders had left by March 2026. Musk publicly said xAI had not been built correctly and was being rebuilt from scratch. Regulatory investigations were opened in the US, UK, France, Canada, and the EU after Grok generated millions of non-consensual explicit images, including images of children. SpaceX disclosed these legal risks in its own IPO filings.
Acquiring Cursor does not fix Grok's legal problems. It does give SpaceX something Grok never had: a product that large companies actually trust and pay for. Cursor's enterprise revenue was growing at roughly $2.6 billion on an annualised basis as of this spring, and its Fortune 500 penetration means SpaceX now has a real foothold in the corporate software market it was pitching investors on during the IPO.
That said, Cursor's position is not as strong as it was a year ago. Its market share in the paid AI coding market fell from around 41% in June 2025 to about 26% by May 2026, according to corporate spending data. The main reason: Anthropic launched Claude Code, its own competing product, in early 2025. Claude Code reached $2.5 billion in annual revenue by February 2026 and has been taking developers away from Cursor, particularly senior engineers who prefer fully autonomous code generation over Cursor's more hands-on model.
So SpaceX is paying $60 billion for a business that is still large and profitable but facing real pressure from Anthropic and, to a lesser extent, Microsoft's GitHub Copilot. The calculation appears to be that owning Cursor's user base and brand, and backing it with SpaceX's computing infrastructure in Memphis, Tennessee, gives the combined business a fighting chance in a market that is growing fast enough to support multiple large players.
For business operators who employ IT staff or work with external developers: AI coding tools are no longer experimental. They are standard infrastructure. The market is now effectively three-way: Cursor under SpaceX, Claude Code under Anthropic, and GitHub Copilot under Microsoft. Your technology teams are almost certainly already using at least one of these, and your procurement and security teams should know which one, under what contract terms, and with whose data policies attached.
