Elon Musk’s SpaceX has struck a deal with artificial intelligence (AI) coding sensation Cursor that gives SpaceX the right to acquire the startup for $60 billion later this year or, alternatively, pay $10 billion for a collaborative partnership.
The announcement, made Tuesday via Musk’s social media platform X, positions the newly formed “SpaceXAI” to challenge industry titans OpenAI and Anthropic.
“SpaceXAI and @cursor_ai are now working closely together to create the world’s best coding and knowledge work AI,” the company said.
By folding Cursor into the SpaceX ecosystem, Musk is not just building a rocket company; he is attempting to construct a vertically integrated AI powerhouse capable of outcoding the very competitors he helped create, according to industry watchers.
“Elon Musk is attempting to warp space and time to leap ahead in the AI race,” said Mitch Ashley, vice president and practice lead, Software Engineering Cycle, at The Futurum Group. “The SpaceX-Cursor arrangement consolidates a vertically and horizontally integrated AI development stack: Colossus compute underneath, xAI foundation models in the middle, and Cursor’s coding product covering the developer workflow above. This is the strategic template AI coding is collapsing toward, matching patterns already visible with OpenAI/Microsoft, Google, and Anthropic/AWS. Competition for the developer workflow is now competition for the full supply chain beneath it.”
Reports over the weekend suggested Cursor was in talks for a $2 billion investment funding round led by Andreessen Horowitz and NVIDIA Corp. at a $50 billion-plus valuation — plans that now appear superseded by the SpaceX agreement.
The acquisition framework was revealed just moments before a New York Times report initially pegged the purchase price at $50 billion. SpaceX’s internal figures suggest a higher premium, reflecting the strategic importance Musk places on Cursor’s Composer model and its dominance in the vibe coding movement, a trend where developers use AI prompts to write and debug complex software.
The partnership is built on a foundation of massive hardware integration. Cursor has already begun utilizing SpaceX’s Colossus supercomputer, which boasts the power of one million NVIDIA H100 chips.
“A meaningful step on our path to build the best place to code with AI,” Cursor CEO Michael Truell said of the deal, noting the collaboration will allow the company to scale its AI models at an unprecedented rate. The deal comes as Cursor’s valuation soars. The startup recently closed a Series D round at $29.3 billion after starting 2025 with a $2.5 billion valuation.
“Enterprises evaluating AI coding agents are now making stack decisions that span silicon, models, and agent behavior inside a single vendor perimeter,” Ashley said. “Procurement teams will need to assess lock-in, model swap flexibility, and governance telemetry across the entire stack before extending coding agents deeper into production workflows. The autonomy ceiling tightens wherever observability cannot cross vendor-integrated boundaries.”
SpaceX’s massive maneuver follows a series of high-stakes corporate restructurings by Musk. In February, Musk merged SpaceX with his AI venture, xAI, in a deal valued at $1.25 trillion.
Nearly a year ago, Musk used xAI to acquire social network X in an all-stock transaction.
SpaceX recently poached top Cursor engineers Andrew Milich and Jason Ginsberg to report directly to Musk.
Musk is currently preparing for a record-breaking SpaceX initial public offering (IPO), with target valuations reaching $2 trillion. While a multibillion-dollar acquisition could complicate SEC filings and potentially delay the public offering, analysts view the move as a necessary step to ensure SpaceXAI possesses the software infrastructure to match its hardware capabilities.
The announcement also arrives just days before the high-profile Musk v. Altman trial begins. The legal battle pits Musk (again) against OpenAI CEO Sam Altman whose company was, ironically, an early investor in Cursor.
