It is not cash though. SpaceX does not have $60B liquid cash instruments.
More accurately it is 3.4% of SpaceX at the last rumored valuation of $1.75T.
There's not going to be $60B of exit liquidity if/when spacex IPOs. Maybe the suckers will be banks lending against the bubble valuation.
No longer rumored as they filed for IPO!
This is actually an amazing sweetheart deal for Cursor. Many times with these high profile acquisitions, most stock is tied to LPA's and employment at the company, and also earnout provisions. The company then finds a way to parachute them out early, which both voids the earnout and their employment, thus they never vest most of the units and the few units they do vest get bought out at 409A valuations which are typically much, much lower.
In the case of Cursor this is an amazing boon as SpaceX listed at an almost 100x multiple which is absolutely staggering. Had SpaceX stayed private they could have 409a'd Cursor and got it for effectively ~100M$ cash.
