I don't believe they have enough money to buy Musk. They can influence him through propaganda and memes, but outright bribery is unlikely. That would have to be a vast, vast money transfer.

Trump looks more likely to be bribe-able than Musk. Very different personalities and net worths. Musk seemed to be genuinely angry with Trump's budget, for example.

Musk’s wealth is tied to Tesla, which from a business perspective is in very deep trouble. But the stock price doesn’t reflect this. I sometimes wonder how much it’s worth to Musk that the stock not reflect Tesla’s actual performance, and who might be driving those irrational price movements.

Why do you think everything can be bought with just money? He might be sold if for trivial things. Some Russian hooker, propaganda and memes, as you said, make him believe siding with Russians makes him more cool. Same things as with the orange guy.
