All the things. Like others have said it’s an insane amount of money.

But realistically, after debt, setting up family, I’d probably buy a (few?) of my dream cars, along with a “project car”. Along with some secured garage somewhere. Also fix up my basement, an/or get a new house (but not into anything crazy, I don’t want a mansion). Find a good charity (or 5) and donate.

But most importantly I’d pay my damn taxes! Not gonna be one of those fucker billionaires that wants to skirt on their basic social responsibility.
