A few days after going public, SpaceX agreed to acquire a leading AI coding tool.
On Tuesday, SpaceX announced it had exercised an option to acquire Cursor, the AI coding assistant made by Anysphere, in a stock deal valued at $60 billion. Cursor will continue to operate independently under CEO Michael Truell, who said the company would now focus on "building the world's most useful AI models" alongside SpaceX.
The deal structure had been quietly in place since April, when SpaceX paid for an option that gave it the right to buy Cursor outright by year-end, or walk away with a $10 billion break-up fee attached to a smaller collaboration. That option preempted a $2 billion funding round Cursor was about to close at a $50 billion valuation, led by Andreessen Horowitz, Thrive Capital and Nvidia. Nvidia CEO Jensen Huang has called Cursor his favorite enterprise AI service, which gives you a sense of the company SpaceX just took off the table.
What made the timing work was the IPO. SpaceX priced its offering at $135 a share last Friday, then watched the stock run past $200 by Tuesday morning, adding close to a trillion dollars in market cap in a few sessions. That run is what paid for Cursor.
"The IPO gave SpaceX a valuation and a premium currency," Franco Granda, senior analyst at PitchBook, told Fortune. He added that SpaceX's dual-class share structure, which leaves Elon Musk in control of nearly all the votes, "removes the last bit of friction" and lets the company move at a speed no normal large-cap acquirer can match.
The strategic logic looks familiar if you've watched Tesla over the past decade. Bret Greenstein, chief AI officer at consulting firm West Monroe, said SpaceX is running the same vertical integration playbook, layering AI software onto a stack that already owns the energy, the data centers and the connectivity through Starlink. Cursor brings the developer-facing product, and a profitable one. The company hit around $2 billion in revenue earlier this year, with SaaS-style margins that look very different from the rest of SpaceX's AI division, which is reportedly burning through roughly $2.5 billion a quarter.
The part nobody is talking about as loudly is what this means for the people actually using Cursor inside companies. Cursor's value to enterprise teams has rested on two things: it works with whatever model you want, and it does not retain your data. Both of those are now subject to a new owner with its own AI lab.
"Cursor's existing zero-data-retention agreements with model providers like OpenAI and Anthropic could be challenged under the new SpaceX ownership, which might quite likely renegotiate or terminate them," Deepika Giri, AVP and head of AI research at IDC Asia/Pacific, told InfoWorld. Her advice for CIOs is to push for change-of-control clauses with 90 to 180 day notice on any subprocessor or model routing changes, because the acquisition, in her words, "completely changes the threat model."
There's also the question of whether Cursor stays model-agnostic at all. The product currently routes to Claude, GPT and Gemini depending on what the developer picks. The new parent company runs xAI and ships Grok. You can do the math on where the defaults might quietly drift over time.
INTO THE VALLEY
The interesting move here is not that SpaceX bought a coding tool. It's that SpaceX used a few days of public-market enthusiasm to buy one before its stock could cool off, in a structure no public-company board would ever wave through. Expect more of this. The companies that went public this year with founder-controlled voting structures and AI-flavored stories now have an acquisition currency that resets weekly, and a roster of private AI startups that would rather take stock than wait two more years for an IPO window that may not open the same way. The Cursor deal is the template. The next one will be faster.
