What happens in the first inning?

Generally, prediction market odds often reflect the wisdom of the crowd and can differ from traditional sportsbook odds. 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 people believe a run will be scored in the first inning, the price of contracts predicting that outcome will rise, potentially exceeding what sportsbooks offer. It’s common to see discrepancies, particularly as new information emerges or public sentiment shifts leading up to the game.

On Kalshi, this market is priced through a continuous auction mechanism. Traders buy and sell contracts representing different outcomes—in this case, whether a run will be scored in the first inning.
