He has way more money than he needs to buy essentially anything. Quadrupling his net worth would have pretty much zero impact on him at this point.
He wants power. Wealth is a route to power (money is ultimately a form of power) but it only goes so far. He maxed that out and now he’s finding other means.
my understanding is that he just got a bit too involved with the culture wars online, a la JK Rowling and your nutso uncle/conspiracy-obsessed facebook friend, but he's just that much more exposed to influence, and that much more powerful, and then he semi-accidentally locked himself into it by buying twitter. I really don't think there's a genius play at the end of it all, or even that it's corruption
It may work out, they are shameless about mixing conflicts of interest in the new regime. I think he might possibly become a trillionaire if Trump actually succeeds and no one stands up to him
