SpaceX paid $60 billion for Cursor four days after the biggest IPO in history, pricing the startup at roughly 23x its $2.6 billion in annualized B2B revenue. The multiple signals what SpaceX couldn’t afford to wait for.
The deal announced June 16 was locked in April, when SpaceX secured the right to buy Cursor’s parent Anysphere at that price or pay a $10 billion breakup fee. Anysphere becomes a wholly owned subsidiary, closing expected Q3 2026. Compare that to Microsoft’s incremental OpenAI stakes, accumulated over years for a minority position. When you can’t build it, you buy all of it.
What does SpaceX actually get? Cursor’s enterprise roster includes Adobe, Stripe, and Nvidia. Jensen Huang called it his “favorite enterprise AI service.” But Cursor’s share of the AI coding market fell from 41% in June 2025 to about 26% by May 2026, per Ramp spending data. Anthropic now controls half the category. The $2 billion round Cursor had been raising from Andreessen Horowitz, Nvidia, and Thrive Capital didn’t close.
The internal AI ledger explains the urgency. SpaceX absorbed xAI in February 2026 at a $1.25 trillion combined valuation. That division posted a $6.35 billion operating loss in 2025 and burned another $2.5 billion in Q1 2026. All 11 xAI co-founders have since left. Musk wrote in March that xAI “was not built right the first time around.” Cursor’s $2.6 billion revenue is the first commercial signal SpaceX AI has produced.
The deal closes Q3 2026. At 23x revenue for a product already losing ground to Anthropic, SpaceX overpaid on the multiple. Whether Cursor can claw back share is the question this deal doesn’t answer.
