Prediction markets let you buy and sell contracts on the outcome of real-world events — elections, economic data, sports, and more. Each contract pays $1 if correct, $0 if not. The price reflects the crowd's live probability estimate.
Unlike sportsbooks, odds aren't set by a house. They're set by traders — which means sharp money moves prices, just like financial markets. That's why prediction markets consistently outperform polls and pundits.
