SpaceX closes $60B Cursor deal, folds it into SpaceXAI unit

SpaceX's $60 billion all-stock takeover of Cursor closed on Thursday, converting outstanding Anysphere shares into 389,289,254 SpaceX Class A shares and folding the coding-tool startup into a new SpaceXAI division, per an 8-K covered by Bloomberg and Yahoo Finance. The merger agreement, signed on June 16, 2026, put Cursor beneath SpaceX via a subsidiary called X67 Inc. and set an implied Cursor equity value of $60.0 billion flat.

The mechanics of the paper matter as much as the sticker price. Every Anysphere common and preferred share converts to SpaceX Class A stock; vested Cursor RSUs pick up another 1,752,426 shares; unvested RSUs and options roll into approximately 29,128,326 assumed SpaceX RSUs and roughly 44,365,047 SpaceX options. What Anysphere's founders and backers now hold is a slug of private SpaceX paper, and the retrieved filings and coverage do not disclose a lock-up, a secondary window, or any cash element that would let holders trim exposure.

The strategic logic was already visible before the ink dried. SpaceXAI and Cursor jointly shipped Grok 4.5, a 1.5 trillion parameter model that reporting says was fine-tuned on Cursor developer session data and trained on Colossus, the Memphis cluster SpaceXAI describes as running roughly 200,000 Nvidia GPUs with plans to grow toward a million. Days earlier the two had pushed a Grok Bot beta out across Mac, iOS, PC, and Linux. That is the data flywheel the deal is built to run: Cursor sessions feed model training, the model ships back into the IDE, and the IDE pulls more sessions. If it works, the marginal training cost of a coding model at SpaceXAI is a lot lower than at rivals that rent GPU capacity, which is one reason this closing is another entry in a heavy recent run of xAI coverage on our tracker.

None of the retrieved coverage names a head for the new SpaceXAI division, and no current Cursor ARR figure appears anywhere I can copy, so the revenue multiple hiding behind the $60 billion tag stays a black box. If the flywheel spins the way SpaceXAI is betting, though, this deal buys distribution into the working day of a lot of developers who currently pay other vendors.
