Will either team score in the first inning?

Typically, prediction market odds reflect the wisdom of the crowd, often differing from initial sportsbook lines. Sportsbooks set odds based on models and public perception, while this market allows individuals to trade on their own informed opinions. As more information becomes available – such as starting pitchers, weather forecasts, and lineup announcements – the prediction market price tends to converge towards what many believe is the true probability of a run being scored in the first inning. However, discrepancies can persist due to differing market participants and risk appetites.

On Kalshi, this market is priced using a continuous double auction. Traders buy and sell contracts representing a 'yes' or 'no' outcome – in this case, whether a run will be scored in the first inning.

This market resolves around Sep 16, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. Specifically, the official game statistics will be used to determine whether at least one run was scored in the first inning. The resolution will be based on the official scoring rules of Major League Baseball. Traders holding a 'yes' contract will receive a payout if a run is scored, while those holding a 'no' contract will receive a payout if no runs are scored during the first inning.

Several factors could influence the price of this market. Key announcements such as the confirmed starting pitchers for both teams, weather forecasts (particularly wind conditions which can impact scoring), and any late-breaking news regarding player injuries or lineup changes are all potential catalysts. Unexpected news about the condition of key hitters or pitchers could significantly shift the market. Furthermore, large volume trades on Kalshi itself can also create price movements, especially if they indicate strong conviction from informed traders.
