Sportsbooks set lines to balance action and protect their margin, while prediction markets aggregate beliefs from traders risking real capital on outcomes. This market may show materially different probabilities than major sportsbooks, particularly if one venue has sharper or more specialized information flow. Comparing the two can reveal where consensus is strongest and where informed traders see value.
