Don't like IPO now for SpaceX

It's probably premature to hold an IPO for SpaceX.

If he had a mature Starship launch system, then yes. Otherwise, no.

You don't have to have a profitable company to go public, so even though SpaceX may be bleeding cash to fund Starship development wouldn't be a barrier normally; the hostility towards Elon Musk may cause trouble down the line.

Lot harder to monkey-wrench his Starship if he keeps it private for now. I say wait until it's proven itself more.
