> Well, the people who bought the SpaceX IPO essentially footed the entire bill here.

It's hard to say that they footed the bill here, but they basically gave SpaceX a number to say "well our stock went IPO and it's at this price, so here's 60B at this price"

A good tactic from SpaceX as after the inital surge of a big IPO, the stock price usually comes down and finds it's correct balance, which is usually always lower. So if they had of waited the 'cooling off' period of a year for example, and the stock price went down to it's 'correct' valuation, then they would have had to issue a higher number of stocks.. At least that's my thinking, but I'm terrible with money.
