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 trader beliefs through continuous price discovery. This market may show different implied probabilities than traditional sports betting sites, particularly as new developments unfold. Comparing the two can reveal where professional bettors and prediction market traders disagree on the likely outcome, offering insight into consensus versus contrarian positioning.

The price of each share reflects the collective assessment of that outcome's probability, ranging from $0 to $1. As traders place bids and asks, the market price adjusts in real time. You can enter limit or market orders to take positions, and your profit or loss is determined by the final settlement price once the event concludes.
