I don't understand where this $80B, +$150B for SpaceX, +$??B for each Anthropic and OpenAI is going to come from.

There's not that much cash sitting around.

Something is gonna need to get sold to transfer into those assets.

Unless central banks are just going to print money to invest in these companies, I don't know who else is going to be able to take on enough debt to prevent massive sell offs somewhere for this.

It's not like ~$400B is pocket change...
