$60b is crazy. Cursor is an extension for VS Code, a harness and a bunch of prompts. They have their own model (Composer 2) which is based Kimi K2.5, but I don't think SpaceX would be interested in it. If they need a harness for grok, they could fork PI. What are they after for here? Customer base? Talent?
Cursor has $4 billion annual revenue rate so $60b is 15 years of future cashflows. That's not crazy because if past predicts the future, that revenue will grow quickly. At $8 billion/year it's just 7.5 years, which is a reasonable investment.
This assumes that Cursor's annual revenue will be the same or higher for over a decade. It's not really like they don't have competitors
