I would bet money that this is not $6bn in cash that has been raised. It sounds like it is the raise at a $24bn valuation, but I'd bet this is less cash and more varied assets or financial instruments.
Whether it's calling Teslas cheap when accounting for your time spent filling up, taking on significant debt rather than selling company shares as Tesla/SpaceX, or leveraging his personal shares for debt, Musk is always pulling some trick to reach numbers like this. That's not to say these sorts of things aren't common among the ultra-rich, but I get the impression Musk does it at every opportunity.
All this to say that I don't think $6bn in cash changed hands for this, I'd expect there's credit lines secured on Musk's own valuation of the company, possibly service credits from compute providers (this can even be via VCs), or other clever tricks to inflate it.
