Prediction market odds and traditional sportsbook odds often diverge because they reflect different participant bases and incentive structures.

This market aggregates the collective forecast of participants willing to stake capital on the outcome. Comparing this market's implied probability to major sportsbook lines can reveal where consensus differs, though prediction markets and bookmakers may weight the same information differently.
