Prediction markets are all about this. They're illegal in the US though, so they haven't really taken off.

If you want to do it with play money though, there's Manifold Markets.

Predictit kind of does this

:maybe-later-kiddo:: "Surely you don't believe the American people are that awful, do you? Of COURSE they'll voot bloo!"

:chad-stalin:: "Ever checked out social media? Everyone laughed at the Buffalo massacre, the Christchurch Massacre, and giggle like first graders over how much they hate non-whites. Fuck Biden for even thinking democracy is the way to go in civilizing these savages."

Prediction markets would be a great way for The Immortal Science to fund itself lol
