SpaceX Locked In Its Cursor Option. The Deal Has Two Doors, Both Lead to SpaceX.

Cursor was in talks for a $50 billion valuation in a new funding round TechCrunch just days before SpaceX announced it had secured an option to buy the company for $60 billion. The jump happened in the time it takes to post an X update. Every outlet covering this has treated that as noise. It is the story.

SpaceX said Monday it has a deal with Cursor giving it the right to acquire the AI coding startup for $60 billion later this year, or to pay $10 billion for ongoing partnership work. Cursor's chief executive Michael Truell confirmed the partnership on his own account. The companies said they will use xAI's Colossus compute cluster to train Cursor's Composer model. Cursor blog post SpaceX and xAI merged in February in a deal valued at $1.25 trillion.

Here is what the announcement does not say: two of Cursor's most senior engineering leaders left the company to join xAI in March. Andrew Milich and Jason Ginsberg are now at Musk's AI lab. That departure came before the announcement, before the valuation jump, and before SpaceX locked in its option. Business Insider Nobody has connected those dots publicly.

The deal structure is a cage with two doors. If SpaceX exercises the option, Cursor sells at a $60 billion valuation that is 24 times what investors assigned it fifteen months earlier. If SpaceX walks away, Cursor keeps the $10 billion partnership payment and whatever credibility the association confers. Neither outcome requires Cursor to remain independent, competitive, or technically differentiated.

Cursor is exposed in a specific way. The company sells access to Claude and GPT models to enterprise customers writing code. Anthropic and OpenAI — the companies whose models fill Cursor's catalog — are simultaneously shipping competing products. Claude Code, Anthropic's own coding agent, competes directly with Cursor's core offering. Cursor pays retail for the models Anthropic sells wholesale to enterprises that then pay Cursor a markup to use them. The SpaceX deal does not close that gap. The $10 billion partnership fee buys compute for Composer, Cursor's own model, but neither Cursor nor xAI has a frontier model that matches what Anthropic or OpenAI ship.

SpaceX is planning a public listing at a $1.75 trillion valuation with a $75 billion raise, which would be the largest in history. CNBC The Cursor option landed four days before jury selection begins in Musk's lawsuit against OpenAI and Sam Altman in Oakland federal court. The timing is either coincidence or the kind of coincidence that shapes narratives at exactly the moment a company needs them shaped.

The overlapping investor base is real and worth naming. Andreessen Horowitz and Nvidia backed both xAI and Cursor. Thrive Capital was slated to co-lead Cursor's standalone round. When the same funds are pricing every major AI infrastructure bet, the market for truly independent companies is narrower than the valuations suggest.

Cursor's annualized revenue crossed $2 billion in February and has grown past that since, according to figures confirmed to Fortune. That is a genuine result. The question is whether it belongs to the company that built it, or to the option holder who can acquire it at a price set before that growth was fully realized.

What to watch next is straightforward: the option has a shelf life tied to the IPO window. If SpaceX exercises before the listing, Cursor becomes a subsidiary of a $1.75 trillion public company. If it doesn't, Cursor is still exposed to Anthropic and OpenAI competing directly with its core product — and the $10 billion payment doesn't close that gap.

The robot says hello. The deal is done. Nobody outside it is better off.
