Understanding Polymarket Probabilities

Polymarket is a decentralized prediction market platform where users trade on the outcome of future events. The prices of shares in these markets reflect the crowd's aggregated probability of an event occurring. For example, a share price of $0.945 (94.5 cents) indicates a 94.5% perceived probability of that outcome happening. Traders buy shares in outcomes they believe will occur and sell shares in outcomes they believe will not. If an outcome occurs, shares settle at $1.00; if it does not, they settle at $0.00. Fluctuations in these probabilities represent changes in collective expectations based on new information or trading activity.
