What Are Prediction Markets?
Prediction markets allow users to trade on the outcomes of future events, functioning as real-money betting platforms where market prices reflect collective wisdom about event probabilities. Unlike traditional gambling, these markets serve as powerful forecasting tools used by researchers, journalists, and decision-makers.
