If it's how it is in my weird African country (Nigeria), I'll wager that most of the money is spent on advertisements and clueless campaign managers and staff enjoying the grift. But then, I understand; the U.S. is a really rich country with a high percentage of politically-active citizens, so they put their money where their mouth is.

You don't even have to give $5800 in most cases. $1k is plenty to get the attention of junior congressmen and even some less well known senators.
Just to put all this in perspective, it's actually possible to get meetings with these people without giving them money, especially if you're a constituent. But the more money you give, the higher you move up in the priority queue, and it doesn't take much to move to the front of the line.
Here's an easy one: "He was only arrested because he was going to reveal damning truth in today's Congressional hearing."
Even if the DOJ, Congress, and SBF all swear until they are black and blue that it wasn't the reason for the timing of the arrest, the theory can change to "Of course they would say that, they are all in on the deep state conspiracy."
The beautiful thing about the world is that there is an unlimited number of unconfirmable and unrefutable possibilities and could-have-beens that can be used to support any idea - sensible, or silly.
Axios wrote that he spent $37 million on the midterms:

I also think the 1 billion figure is inaccurate. In May, SBF said that he could spend a billion between now and 2024. However, he backed away from that quote in October:

Elon Musk later said that SBF “probably” donated over 1 billion, without providing any supporting evidence. I can’t prove that he’s thinking of the May statement but it seems plausible if not certain. Either way, Elon Musk’s guesses are not proof of anything.
I’m glad you asked for sources. It’s always important to provide them.
