Understanding Prediction Markets

Prediction markets, like those on Polymarket, aggregate decentralized information and expectations into tradable probabilities. The probability displayed for a market represents the consensus belief of traders on the likelihood of a specific event occurring. A probability of 0.50 (or 50%) indicates a 50% chance, while a probability of 0.05 (or 5%) suggests a 5% chance. These probabilities are dynamic and can change rapidly based on new information, market sentiment, and trading activity. The odds are determined by the price at which YES and NO shares trade. For example, if YES shares are trading at $0.10, the market implies a 10% probability of the event occurring.
