On Kalshi, traders actively set the price through buying and selling contracts, with the current chance reflecting aggregated expectations about which team will score first in the inning. The top outcome’s probability is displayed as a percentage, derived from real-time trading volume and order book depth.

This market resolves around Aug 26, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The result is determined by which team scores the first run in the first inning of the game, as officially recorded in game statistics.
Several factors could shift expectations in this market before Aug 26, 2026. Key pitcher performance updates, such as injuries or sudden changes in starting lineups, may dramatically alter probabilities. Weather conditions affecting game play, like rain delays or temperature impacts on ball movement, can also influence trader sentiment. Additionally, recent team performance trends — particularly early-inning scoring rates — might cause rapid shifts in the market as traders reassess odds. Any last-minute roster decisions will likely drive volatility in this market.
