How Prediction Markets Work

According to their boosters, prediction markets such as Polymarket or Kalshi are ‘global truth machines’; their detractors say they’re just a glorified form of gambling. Either way, they’re zero-sum games with, as Geoff Mann put it recently in the LRB, ‘few winners and many losers’. On this episode, he joins Thomas Jones to discuss how prediction markets work, who profits from them, who regulates them (or doesn’t), why they’re often a very bad tool for predicting the future, and what they may tell us about the state of the world.
