Technically his total wealth has declined to about $342 Bn, and technically that is only if he sold off all of his assets namely his Tesla stocks, at which point it would instantly become less than $342 Bn due to the market’s fast acting supply/demand price setting.

At any given time you should assume Musk has less than $30 Bn liquidity, which is still a fucking lot.

Also, he bought Twitter so you can say he spent a lot more than $300 to elect Trump. $300 was just his campaign contributions.
