$60 billion to own it outright. $10 billion to walk away with whatever they build together. Those are the terms SpaceX attached to its deal with AI coding startup Cursor, announced Tuesday on X — and the spread between those two numbers tells you more about Elon Musk’s strategy than any press release could.

The structure is straightforward, if staggering. SpaceX gets the right to acquire Cursor later this year for $60 billion, or pay $10 billion for what the company’s statement called “our work together.” In the meantime, the two companies will collaborate on building what SpaceX described as “the world’s best coding and knowledge work AI,” combining Cursor’s developer tools with SpaceX’s Colossus supercomputer — a system the company claims packs the equivalent of a million Nvidia H100 chips.

The Valuation Logic — or Lack Thereof

The $60 billion acquisition price needs context, and the context is vertigo-inducing. Cursor was valued at $2.5 billion in January 2025. By May, that had climbed to $9 billion. A $2.3 billion Series D round in November assigned the company a $29.3 billion post-money valuation. As of last weekend, Cursor was in talks to raise $2 billion at a $50 billion valuation, with Andreessen Horowitz co-leading and Nvidia and Thrive Capital expected to participate, according to CNBC.

Even against that trajectory, $60 billion represents a premium of at least 20 percent over Cursor’s latest fundraising talks — and a valuation that would have been unthinkable for a coding tool eighteen months ago. The question is whether SpaceX is paying for Cursor’s technology, its distribution among software engineers, or simply the ability to keep it away from competitors.

Neither Cursor nor xAI, Musk’s AI division, has proprietary models that can match the leading offerings from Anthropic and OpenAI — the same companies now competing directly with Cursor for the developer market. According to TechCrunch, Cursor still uses and sells access to Claude and GPT models even as Anthropic and OpenAI roll out their own coding tools. It is an awkward arrangement, and one this deal appears designed to escape.

Compute as Connective Tissue

The partnership’s immediate engine is computing power. xAI is supplying Cursor with access to its data centers, with the coding startup using tens of thousands of xAI chips to train its latest AI model, according to TechCrunch. Business Insider reported that Colossus is powered by 200,000 Nvidia GPUs.

This is where the empire-building logic clicks into place. Musk merged xAI with SpaceX in February in a deal he valued at $1.25 trillion. SpaceX confidentially filed for an IPO in early April, setting the stage for what will likely be a record public debut. Bolting Cursor onto that structure gives the combined company a credible AI applications business to sit alongside its infrastructure and social media holdings — and gives potential IPO investors a growth narrative that extends beyond rockets and chatbots.

The talent pipeline is already flowing. Two of Cursor’s most senior engineering leaders, Andrew Milich and Jason Ginsberg, left the company last month to join xAI, where both report directly to Musk, according to TechCrunch. Musk acknowledged at a recent conference that Grok, xAI’s chatbot, “is currently behind in coding.”

Who Loses

If SpaceX controls both the computing infrastructure and one of the most popular AI coding platforms, the competitive casualties stack up fast. Anthropic and OpenAI lose a major distribution channel — Cursor’s developer base — if the tool shifts exclusively to xAI’s models. Andreessen Horowitz, Nvidia, and Thrive Capital, which were preparing to invest in Cursor at $50 billion, now find themselves negotiating against an acquirer who set the price $10 billion higher.

Then there is the timing. The announcement landed just before a New York Times report that SpaceX had agreed to purchase Cursor for $50 billion — a figure SpaceX effectively corrected upward by posting its own terms. Less than a week from now, Musk is scheduled to appear in a Northern California court for a high-profile case against OpenAI CEO Sam Altman, whose company was an early investor in Cursor. The threads are not subtle.

The Empire’s Edges

Musk has now used SpaceX as the vehicle to absorb xAI, the social media platform X, and potentially one of the fastest-growing AI tools on the market. The man who builds rockets, runs a social network, and trains AI models wants to own the tool that writes the code for all three.

The Slop News, a newsroom that would not exist without AI coding tools, notes this consolidation with professional interest.

Cursor CEO Michael Truell wrote on X that he is “Excited to partner with the SpaceX team to scale up Composer,” referring to the company’s AI model. Neither SpaceX nor Cursor responded to requests for comment from multiple outlets.

The deal still needs to close. But the signal is clear enough: Musk is not building an AI company. He is building a company where AI is the operating system — and he is willing to pay extraordinary sums to ensure the key components are owned, not rented.
