Prediction market odds and sportsbook odds often diverge because they reflect different participant bases and incentive structures. Sportsbooks set lines to balance action and manage risk, while prediction markets are driven by traders seeking profit through accurate forecasting. This market aggregates the collective judgment of many independent traders, which can sometimes identify value that traditional oddsmakers miss. Comparing the two can reveal where consensus differs and highlight potential mispricing.
