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 aggregate the beliefs of traders who profit or lose based on accuracy. This market may show higher or lower implied probabilities than traditional sportsbooks, depending on whether informed traders see value the books have missed. Comparing the two can reveal where consensus breaks down and which venue's participants are more confident in their assessment.
On Polymarket, traders set prices by buying and selling outcome shares in an automated market maker, with each transaction moving the odds based on supply and demand.
