Context on Prediction Markets

Prediction markets, such as Polymarket, aggregate the beliefs of participants by allowing them to trade contracts whose value is tied to the outcome of real-world events. The probability displayed in a prediction market is derived from the last traded price of a contract. For instance, if a contract representing an event resolving "Yes" trades at $0.50, the market assigns a 50% probability to that event occurring. These markets can react quickly to new information, and price movements reflect a collective, albeit speculative, assessment of future outcomes. It is crucial to distinguish between the probability reflected in the market and confirmed outcomes or future predictions.
