SpaceX agreed on Tuesday to acquire Anysphere, the company behind the AI coding tool Cursor, for $60 billion in an all-stock transaction disclosed in a regulatory filing two trading days after its Nasdaq debut. The takeover formalises a call option SpaceX negotiated in April, when Cursor was already on track to close a $2 billion funding round at a $50 billion valuation before SpaceX intervened.

The mechanics are the story. SpaceX shares closed Tuesday at $211.27, up roughly 16 percent on the day and more than 56 percent from the $135 IPO price, vaulting the company into the fourth most valuable U.S. company by market capitalisation. Cursor investors are being paid in SpaceX class A common stock, which CNBC pegs at about 3.4 percent dilution at the acquirer’s IPO valuation. Reuters notes that no IPO proceeds are funding the deal. None are needed. The currency is the equity itself.

Investor Bill Ackman, posting on X, observed that the high valuation lowered the dilution cost of the deal. That’s the entire logic of the post-IPO acquisition wave in compressed form, and it echoes the AOL–Time Warner equity arithmetic of January 2000, where a richly priced acquirer prints stock against a target before the multiple compresses.

The strategic case is more strained. Cursor crossed $1 billion in annualised revenue in November and now sits near $2.6 billion in B2B revenue, per Reuters. But Ramp spending data cited by CNBC shows its market share sliding from 41 percent in June 2025 to roughly 26 percent in May, as Anthropic and OpenAI close in. IPO filings detail a $1.5 billion termination fee and $8.5 billion in committed computing resources had the deal collapsed.

It won’t. Following February’s absorption of xAI, SpaceX is now assembling an AI stack with its own stock as the acquisition vehicle. Closing is expected in the third quarter.
