Future TechnologySpaceX just paid $60 billion for Cursor, the coding tool your developers cannot quit
Key takeaways
- SpaceX is acquiring Anysphere, the company behind AI coding tool Cursor, for $60 billion in an all-stock deal
- It is the largest acquisition of a venture-backed startup on record, signed four trading days after SpaceX's $75 billion IPO
- Cursor reached roughly $4 billion in annual revenue in under four years, about $2.6 billion of it from enterprise customers
- The real prize is data, compute and talent: Cursor's coding data feeds Grok, and xAI badly needed the people
On June 16, SpaceX said it is buying Anysphere, the company behind the AI coding assistant Cursor, for $60 billion in an all-stock deal. That makes it the largest acquisition of a venture-backed startup anyone has recorded. It landed four trading days after SpaceX's own Nasdaq debut on June 12, an IPO that raised $75 billion at $135 a share and was itself the biggest in history.
Two records in one week, from the same company. Worth pausing on that.
Why a rocket company wants a code editor
On the surface it makes no sense. SpaceX launches rockets. Cursor helps engineers write software faster by wrapping AI models around a familiar code editor. The link is xAI, Elon Musk's AI company, and the plan to fold Cursor into it.
Cursor is not a small bet. It reached around $4 billion in annualised revenue in under four years, with roughly $2.6 billion of that coming from enterprise customers paying for whole engineering teams. If your developers use an AI editor, there is a good chance it is this one.
But revenue is not really the point. SpaceX is buying three things money cannot quickly build: data, compute and people. Every keystroke in Cursor is training data on how real engineers solve real problems, and that feeds straight into Grok's training pipeline. In return, Cursor gets access to xAI's Colossus supercluster. And the deal fills a talent hole: by the end of March, all eleven of xAI's co-founders had left.
What it signals
This is the clearest sign yet that AI coding infrastructure is now valued like the legacy enterprise software giants. A tool that did not exist in 2021 is changing hands for more than the market value of plenty of household-name companies.
There is a quieter point for anyone who actually uses Cursor. Your codebase now sits one step away from SpaceX, and by extension Grok. The deal is expected to close in the third quarter of 2026, subject to regulatory approval, and a $10 billion walk-away fee was baked into the option agreement signed back in April. Regulators in the US and Europe will have questions about that much code data flowing into one company.
Whether this is the trade of the decade or the most expensive text editor ever sold, it tells you where Musk thinks the leverage is. Not in the rockets. In who controls how code gets written.
