Cursor Joins SpaceX: AI Coding Meets the World's Largest GPU Fleet
Cursor Is Joining SpaceX
Cursor, the AI-powered coding platform, has been officially acquired by SpaceX, completing a process that began in April with a partnership to accelerate model training. With access to SpaceX's massive GPU infrastructure, Cursor aims to build more powerful and cost-efficient models, expanding its capabilities from code completion to AI teammates. The recent release of Grok 4.6 offers a glimpse of what's possible, as Cursor becomes a key interface for SpaceX's advanced intelligence.
Together with SpaceX, we will push that ambition further.

Keep in mind while this is the date they officially became part of SpaceX, they have already been collaborating on building models together. So don't expect a significant bump in performance on new Grok models due to the additional data from Cursor--that bump already happened with Grok 4.5[1] and now 4.6.

I'm skeptical of this deal. Cursor led the way on agentic coding, but Claude Code and Codex have replaced it. [I use Codex for everything now.]
Still, I'm hearing that Grok 4.6 is almost as good at coding as Codex, but lots cheaper. [My network is also down on Claude--Opus 5 seems like a regression.]
The optimistic scenario would be Grok being a fast-follower with cheaper rates, and staying ahead of open source models. If they can pull that off, and convince enough developers, then maybe they've got a chance.
But $60B seems insane to me. What's Cursor's market share relative to Codex and Claude Code? If it's not meaningful, then it's $60B for an acquihire.

I feel like people aren’t updating to the possibility that a significant portion of software development could be under the purview of SpaceX. Whether it’s developer Twitter, Cursor’s planned GitHub competitor, or Cursor/Grok, that’s a lot of the developer mindshare. Granted, there’s a lot of competition in all of these spaces except for maybe Twitter, so it might not happen. But there’s a chance! And that possibility is fairly concerning.

Elon is still all in on replacing programmers. He listens to always the same stupid booster accounts (XFreeze etc.).
Good that there is now an administration that creates jobs, does not engage in foreign wars and has ended the Ukraine war in 24 hours.

Isn't it SpaceXAI now? I lost track.

Subscription is gone the second I feel like their not running the inference at a loss

Cooool, won't be using that again

Will they rebrand as codeX or Xcode? Trouble either way.
