SpaceX closes its $60B purchase of Cursor

Cursor arrives as a large business, not an acqui-hire. Dealroom reported in June that its annualised revenue had passed $4 billion, up from $2 billion in February, with roughly three-quarters coming from enterprise customers. It now sits inside SpaceX's AI division, with access to the company's Colossus supercomputer.

What hasn't been said

The open questions matter more than the price. Neither company has said publicly whether Cursor will keep treating third-party models such as Claude, GPT and Gemini as first-class options, or what happens to existing plans. Investing.com's report says the Cursor brand is expected to give way to Grok branding over time. SpaceX hasn't confirmed that.

That's the bit worth thinking about. When a tool your team uses every day changes owner, the risk usually isn't that it disappears overnight. It's that the defaults drift: which model it picks for you, what your plan includes, where your code and prompts get sent. None of that needs an announcement.

If you run a dev shop or an agency with a build team, there's a second question: what you've promised clients. Some client contracts and security questionnaires name the tools and model providers that touch their code. A change of owner, and possibly of default model, is worth a line in your next update to them.

What to do this week

Nothing dramatic. Don't migrate a team mid-sprint because of a headline. Do the cheap things that keep you free to move:

1. Write down which Cursor features your team actually leans on. Most teams use three or four, and those are your real switching cost.
2. Move rules files, prompts and agent instructions into the repo if they only live in the editor's settings. Files in the repo move between editors in an afternoon.
3. Check which model each person has set as their default, and decide whether that's a team decision or a personal one.
4. Note your plan's renewal date and what it includes today, so you'll notice if it changes.
5. If you have clients who care where their code goes, mention the change of ownership in your next status note.

Then get on with your week. If the model line-up or the pricing changes, you'll be making a calm decision rather than a rushed one.
