Which term describes a market mechanism for predicting future events' outcomes beyond traditional sportsbooks?

• A. Forecast exchange
• B. Sportsbook
• C. Betting pool
• D. Prediction market

Answer: (D)

Prediction markets describe a market mechanism for forecasting future events by trading contracts whose payoff depends on the event’s outcome. The price of a contract reflects the market’s probability assessment, and as information shifts, traders buy or sell to push prices toward new, more accurate probabilities. This setup aggregates knowledge from many participants, often yielding more reliable predictions than relying on a single expert or traditional opinion. It differs from a sportsbook, which focuses on sports outcomes with fixed odds set by bookmakers and emphasizes wagering on games rather than continuous information-driven price discovery. It also differs from a betting pool, where bets are pooled and winnings are split without dynamic trading or real-time price signals. A forecast exchange is a related idea and sometimes used interchangeably, but the term that best captures this broad market mechanism for predicting future events is prediction market.
