Typically, prediction market odds reflect the wisdom of the crowd, often differing from initial sportsbook offerings. Sportsbooks set lines based on their own models and to balance action, while this market aggregates the beliefs of many individual traders. If a significant number of traders believe a sportsbook has mispriced an outcome, they can express that view by trading on Polymarket. This can lead to prediction market odds diverging from, or converging towards, sportsbook lines as new information becomes available and opinions shift. It's common to see differences, especially before the event begins.
