SpaceX closed a $60 billion deal and officially acquired the AI startup Cursor
Cursor, the startup known for its AI coding tool, is now officially under SpaceX control.
The companies announced the deal back in June, but the process of coming together actually started in April, when they teamed up to train Cursor models.
In a blog post, Cursor said it now has access to "the largest fleet of GPUs in the world." That kind of computing power should let the company build and train better models, then offer them to customers at a noticeably lower cost.
SpaceX "paid" $60 billion for the acquisition. In practice, no actual money changed hands – the whole deal is based on SpaceX stock. Earlier this year, the aerospace company had already absorbed Elon Musk's AI company xAI, which officially became SpaceXAI in July.
Shortly after the rebrand, SpaceXAI and Cursor released Grok 4.5, the first model they built together. It was designed to "excel at coding, agentic tasks and knowledge work," while delivering results "at far lower costs."
Grok 4.6 followed, building on its predecessor. The newer model was trained to handle real world tasks like general coding, web development and computer-aided design.
Cursor described Grok 4.6 as an early look at what the team can build together with SpaceXAI. Pairing Musk computing infrastructure with developer tools creates a setup where model training and the coding product evolve within the same structure.
