Prediction market odds and sportsbook odds often diverge because they serve different purposes and audiences. Sportsbooks set odds to balance their book and manage risk, while prediction markets aggregate the collective beliefs of traders who profit or lose based on accuracy. This market reflects what informed traders believe will happen, which can differ meaningfully from traditional betting lines. Comparing the two can reveal where the broader market sees value or where consensus differs from professional oddsmakers.
