It’s people who put their money where their mouth is. They think someone’s gonna win, they buy the position and sell when the guy wins. Their position becomes worthless if he loses. It’s a futures market for politics.
If anyone can astroturf this market, it’s a guy with a lot of money followers. Maybe someone like Soros could do it, but it’s no fun to pour money down a rathole.
What do you get for buying a winner after the election? that makes no sense. the election is over ALL positions like tht are worthless.
