SpaceX has agreed to buy Cursor, the AI-powered code editor built by parent company Anysphere, in a deal valued at $60 billion in Class A common stock. Instead of a cash payout, Cursor’s investors will receive direct equity in SpaceX, effectively converting their stake in a software startup into ownership of one of the most valuable private companies on the planet.
The acquisition is expected to close in Q3 2026 and will result in approximately 3.4% dilution based on SpaceX’s post-IPO valuation.
From partnership to acquisition in two months
This deal didn’t materialize overnight. Back on April 21, 2026, SpaceX announced a partnership with Cursor that included a call option to acquire the company for the same $60 billion figure. The alternative path would have seen SpaceX pay a $10 billion fee for a collaborative arrangement involving the xAI-developed Colossus supercomputer infrastructure, which boasts million-H100-equivalent capacity.
Cursor’s flagship offering is the Composer model, an AI system designed to function as an autonomous coding agent for software engineers.
