SpaceX has agreed to acquire the AI coding startup Cursor for sixty billion dollars in an all-stock deal announced Tuesday, only days after SpaceX went public at a valuation of roughly 1.77 trillion dollars. The acquisition feeds SpaceX's AI division, which was built around xAI after the two companies merged earlier this year, and is expected to close in the third quarter.
The terms trace back to a pre-IPO agreement from April that gave SpaceX the option to buy Cursor for sixty billion in stock or pay a ten-billion-dollar break-up fee. That price is a sharp step up from Cursor's earlier valuation of about twenty-nine billion, and it supersedes a separate round of roughly two billion dollars that Cursor had been raising from Andreessen Horowitz, Thrive, and NVIDIA at a fifty-billion-dollar valuation. Cursor, founded in 2022 as Anysphere, had previously raised a nine-hundred-million-dollar Series C in June 2025 and another 2.3 billion later that year.
The deal arrives against a turbulent backdrop at xAI: all eleven of its co-founders had departed by the end of March, and Elon Musk has said publicly that xAI "was not built right the first time around." In the run-up to the acquisition, xAI had already hired two senior Cursor engineering leaders and rented data-center capacity to the startup, suggesting the integration has been underway for months. SpaceX pitched IPO investors on a total addressable market of roughly twenty-eight trillion dollars, of which it attributes about twenty-six trillion to AI, split between 2.4 trillion in AI infrastructure and 22.7 trillion in enterprise applications.
The market response has been dramatic. Since Friday's IPO, SpaceX stock climbed from around 135 dollars to over 200 in Tuesday pre-market trading, adding close to a trillion dollars in value, which one observer noted is "roughly sixteen Cursors." The transaction is one of the largest all-stock acquisitions in the AI sector to date and marks the vertical absorption of a leading coding-assistant lab into a launch-and-satellite company anchoring a new AI strategy. The main open questions are execution: the deal still has to close, and the earlier exodus of xAI's founding team leaves real integration risk around the combined AI organization.
- TechCrunch frames the deal as a lifeline for SpaceX's struggling AI division and quantifies the ~$28T total addressable market pitch.
- The Information stresses the timing: announced Tuesday, days after a $1.77T IPO that had already added roughly a trillion dollars in market value.
- Both note the price reset upward from Cursor's earlier ~$29B and the abandoned $50B a16z/Thrive/NVIDIA round.
