Who will lead after 3 innings: St. Louis vs Chicago Cubs?

Prediction market odds and traditional sportsbook odds often diverge because they reflect different participant bases and incentive structures. Sportsbooks set lines to balance action and lock in profit margins, while prediction markets like this one aggregate the genuine beliefs of traders risking real capital. For this market, comparing the prediction market price to major sportsbook lines on the same matchup can reveal whether informed traders see value the books may have missed or mispriced. Both sources offer useful signals, but they operate independently.
