Here’s a deal nobody had on their bingo card: SpaceX has secured an option to acquire Cursor, the AI code editor, for $60 billion. If the acquisition doesn’t go through, SpaceX pays $10 billion as a breakup fee for the partnership work. Bloomberg, CNBC, and TechCrunch all confirmed the agreement independently on April 21.
Why Would SpaceX Want a Code Editor?
Rockets and code editors — not an obvious combination. But the backstory makes sense. xAI, Musk’s AI company, has been renting compute power from its Colossus supercomputer to Cursor — the equivalent of a million Nvidia H100 chips. Two senior Cursor engineers recently moved to xAI.
The core problem: neither Cursor nor xAI has proprietary models that match the leading offerings from Anthropic and OpenAI. Cursor currently runs primarily on Claude and GPT models. An acquisition could fundamentally change that arrangement.
From $2.5B to $60B in 15 Months
Cursor’s valuation trajectory is staggering: $2.5 billion in January 2025, $9 billion by May, $29.3 billion when it closed its Series D in November. Now a new $2 billion round at a $50 billion valuation is in the works, led by Thrive and Andreessen Horowitz.
The numbers backing it up: Cursor hit $2 billion in annualized revenue by February 2026, with projections of $6 billion by year-end.
Why Not Buy Now?
SpaceX is gearing up for its own IPO. An acquisition of this size would complicate the filings and potentially delay the timeline. Hence an option rather than an outright purchase.
What This Means for AI Coding
A SpaceX-Cursor deal would reshuffle the AI coding landscape. Cursor sits alongside Claude Code and GitHub Copilot as one of three dominant AI coding assistants. Integration into the xAI ecosystem could mean Cursor eventually runs on Grok models instead of Claude and GPT — a loss for Anthropic and OpenAI, a win for Musk’s AI ambitions.
The real question: will Cursor get better under Musk, or will it lose exactly the model quality that made it successful?
