On Polymarket, this market is priced through aggregated trader sentiment, which often differs from traditional sportsbook odds that incorporate bookmaker margins and different risk models. Prediction markets may reflect sharper or more volatile pricing depending on recent trading activity and volume of $650,151. Sportsbook odds typically include a built-in house edge, making them generally less favorable to bettors than prediction market probabilities, which converge toward perceived true odds. The gap between the two can widen if Polymarket sees heavy speculative flow or if sportsbooks adjust for perceived public bias in the National Bank Open tennis match.
