SpaceX closes $60 billion Cursor acquisition, AI coding tool joins Colossus GPU cluster
SpaceX officially closed its $60 billion all-stock acquisition of Cursor on August 14-15. Cursor's engineering team joins SpaceX's software division with direct access to the Colossus GPU cluster and joint training with xAI's Grok 4.6.
Cursor confirmed on its official blog on August 15 that SpaceX has closed its $60 billion all-stock acquisition of Cursor parent Anysphere on August 14-15. The deal is SpaceX's key AI application-layer move after the xAI acquisition. Cursor's engineering team has moved into SpaceX's software division, while the technology cooperation agreement signed on April 21 took effect simultaneously.
Post-acquisition, Cursor has direct access to SpaceX's Colossus GPU cluster, the same infrastructure SpaceX already leases to Anthropic and Google for training compute. Cursor stated in its announcement that it will have access to "the largest fleet of GPUs in the world," enabling stronger and more economical model training.
As a first showcase of the collaboration, Cursor and xAI jointly released Grok 4.5 in July, with Grok 4.6 rolling out in the Cursor editor on August 12. Cursor's blog called these the first models produced under the collaboration, with plans for a GitHub competitor.
Deal timeline: April 21, SpaceX and Cursor signed a cooperation agreement with a $60 billion acquisition option; June 16, the week of SpaceX's IPO, both parties confirmed moving forward; August 14-15, the transaction officially closed. Cursor shareholders received about 389 million SpaceX Class A shares, with unvested RSUs and options converted simultaneously.
