SpaceX has taken out an option to either buy AI coding startup Cursor for $60 billion later this year or pay $10 billion for the work the two companies are already doing together. Elon Musk's rocket firm announced the deal in an SpaceX post Tuesday, and Cursor CEO Michael Truell confirmed it shortly after.
A deal with two prices
The structure is unusual enough to deserve a second read. SpaceX gets to decide whether to acquire Cursor outright or simply cut a ten-figure check for services rendered. Same agreement, two very different outcomes. The New York Times had reportedly gone to press with a $50 billion acquisition story before SpaceX's post forced a revision to the higher number.
Cursor was already in talks to raise $2 billion at a valuation over $50 billion, per CNBC. Andreessen Horowitz was set to co-lead the round, with Nvidia and Thrive Capital participating. Both Andreessen and Nvidia also backed xAI, which makes the circle tight and the $60 billion headline price less jarring than it first reads.
"Excited to partner with the SpaceX team to scale up Composer. A meaningful step on our path to build the best place to code with AI."
That's Truell on X, and it's the kind of founder statement you write when the CEO of your largest prospective acquirer also happens to own the platform you're posting on.
The IPO math
Context matters. SpaceX confidentially filed for an IPO earlier this month, and anything that bulks up its AI story before the S-1 lands in public view has obvious appeal. Musk merged SpaceX with xAI in February at a combined valuation he put at $1.25 trillion. Bolting on the hottest product in AI coding, at almost any price, reads as narrative preparation as much as strategy.
Whether Cursor is actually worth $60 billion is a different question. Its growth is hard to argue with, but its models aren't proprietary. Cursor still sells access to Anthropic's Claude and OpenAI's GPT, an awkward arrangement now that TechCrunch points out both of those companies are shipping competing coding tools. The SpaceX deal is probably designed to eventually escape that dependency.
Compute for distribution
Strip away the marketing and the pitch is a straight trade. Cursor gets access to Colossus, the xAI supercomputer SpaceX claims has the compute equivalent of a million Nvidia H100 chips. In exchange, SpaceX and xAI get a distribution channel into hundreds of thousands of professional software engineers who open Cursor every morning.
The talent pipeline has been running for a while. Last month, two of Cursor's senior engineering leaders, Andrew Milich and Jason Ginsberg, left to join xAI and report directly to Musk. Last week, xAI reportedly started renting out compute to Cursor for training its latest model. Tuesday's announcement formalized what was already happening quietly.
SpaceX hasn't said when it will exercise the option, only that the decision comes later this year. The Musk v. Altman trial, the long-running feud between Musk and the OpenAI CEO, is scheduled to begin next week.
