SpaceX closes $60B Cursor acquisition, gains GPU fleet

SpaceX has officially closed its $60 billion acquisition of AI coding startup Cursor, a deal that gives Cursor access to what it calls "the largest fleet of GPUs in the world." The acquisition, announced in June, was completed on schedule in the third quarter after regulatory approval, according to a regulatory filing Source: The Next Web. Cursor will retain its name and blog, operating under its legal entity Anysphere Source: The Next Web.

Deal details

The acquisition began in April when Cursor partnered with SpaceXAI (formerly xAI) for model training, with SpaceX gaining an option to acquire Cursor for $60 billion Source: TechCrunch. SpaceX merged with xAI earlier this year, and the combined entity now rents computing infrastructure to customers including Anthropic and Google Source: TechCrunch. Cursor says the deal will enable it to build stronger models at lower cost for customers Source: Engadget.

Grok integration

Cursor and SpaceXAI have already shipped models together. Grok 4.5, released in July, was the first model built jointly, and Grok 4.6, released Wednesday, is now available in Cursor Source: Engadget. SpaceXAI claims Grok 4.6 matches OpenAI's GPT-5.6 Sol on several benchmarks, including the Artificial Analysis Intelligence Index Source: Gizmodo. Elon Musk called Grok 4.6 "objectively #1 when considering intelligence, speed & cost" Source: Gizmodo.

Competitive landscape

The deal is part of Musk's bid to catch up with Anthropic and OpenAI in AI coding Source: The Next Web. Notably, Anthropic is both a rival and a customer, having agreed to pay SpaceX close to $45 billion for computing Source: The Next Web. SpaceXAI also launched Grok Bot, an always-on AI agent service, in beta this week Source: The Verge.

What's next

Musk told staff that AI revenue would out-earn rockets by September and significantly exceed the rest in the fourth quarter Source: The Next Web. Cursor, which was still acquiring companies the day before the deal closed, will continue its own transactions Source: The Next Web.
