SpaceX strikes $60B deal with Cursor to build AI coding models using Colossus supercomputer

SpaceX has struck a landmark deal with AI coding startup Cursor, securing the option to acquire the four-year-old company for $60 billion later this year or pay $10 billion for their collaborative work if the purchase does not proceed. The agreement, announced Tuesday, pairs Cursor's popular software development platform—used by expert engineers to automate coding—with SpaceX's massive Colossus supercomputer, equivalent to a million Nvidia H100 chips, to build next-generation AI for coding and knowledge work. According to SpaceX's statement on X, this combination aims to create "the world's most useful models," giving Elon Musk's rocket company a bold entry into the fiercely competitive AI developer tools market.

Cursor, founded in 2022, has rocketed from a $2.5 billion valuation in early 2025 to $29.3 billion post-money after raising $2.3 billion in a Series D round last November, when it also hit $1 billion in annual recurring revenue with over 300 employees. As reported by Business Insider, the startup's rapid growth reflects the exploding demand for AI tools that streamline programming, putting it in direct competition with giants like OpenAI and Anthropic. TechCrunch notes that last week Cursor was eyeing a $50 billion valuation in private fundraising, underscoring how this deal could lock in an even higher price amid the AI boom. Cursor co-founder Michael Truell expressed excitement on X about partnering to "scale up Composer," their key product for AI-assisted coding.

The partnership addresses key weaknesses for both sides. SpaceX, which acquired Musk's xAI in February and recently filed confidentially for an IPO, gains Cursor's established product and developer distribution to bolster its AI efforts, where xAI's models have lagged behind rivals. Bloomberg highlights how this move helps SpaceX catch up in AI coding tools, a sector with early commercial success, while Cursor taps into Colossus's unmatched computing power—powered by 200,000 Nvidia GPUs—for training advanced models. Reuters reports that two Cursor product engineering heads defected to SpaceX in March to work on lunar projects and xAI, signaling deepening ties even before the deal.

This development arrives at a critical juncture for Musk's empire, which now spans rockets, AI via xAI, and social media through X—all potentially bundled in the anticipated SpaceX public offering. TechCrunch points out that investors may view the Cursor engagement as a value booster for the IPO, especially as SpaceX faces financial pressures from recent acquisitions and heavy capital spending. For the broader AI landscape, the deal intensifies the race to dominate automated software development, where companies like Anthropic lead but face aggressive challengers. Cursor's employees, developers relying on its platform, and SpaceX shareholders stand to be most affected, with the outcome hinging on whether the $60 billion acquisition materializes later this year.

What happens next remains fluid: SpaceX must decide on the full buyout or the $10 billion payment by an undisclosed date, amid questions over whether stock could factor into the terms. The arrangement, described by TechBuzz as a "bombshell" with a massive breakup fee, has already drawn Silicon Valley scrutiny for its scale and structure. As Musk pushes deeper into AI, this bet on Cursor could redefine SpaceX's role beyond spaceflight, accelerating innovations that automate coding for industries worldwide.
