Zuffa Boxing 8: Santos vs. Valenzuela (Lightweight, Main)

Prediction market odds and sportsbook odds often diverge because they reflect different participant bases and incentive structures. Sportsbooks set lines to balance action and lock in profit margins, while prediction markets like this one are driven by traders seeking to profit from accurate forecasts. This market aggregates the collective judgment of many independent participants without a house edge, which can lead to sharper pricing on major events. Comparing the two can reveal where professional bettors and prediction market traders disagree on fight outcomes.
