Description

This event tracks the performance gap between two teams in an upcoming baseball game. It focuses on how many runs one team surpasses the other by at the end of the match. The outcome depends entirely on the final score difference between the two competing teams.

Kalshi

The event evaluates various run-difference thresholds for both teams in a single baseball game scheduled for September 12, 2026. Each rule corresponds to a specific run margin that, if achieved by either Kansas City or Boston, will resolve the market to 'Yes'. Thresholds range from 1.5 to 3.5 runs for both teams, meaning any victory by more than 1.5 runs for either side meets at least one market condition. The market resolves positively if Boston wins by over 1.5, 2.5, or 3.5 runs, or if Kansas City wins by over 1.5, 2.5, or 3.5 runs. If neither team meets any of these margins — for example, if the game ends in a tie, or one team wins by exactly the listed run values (e.g., exactly 1.5, 2.5, or 3.5 runs) — the market resolves to 'No'. All rules share the same game reference date, time, and governing disclaimer regarding Kalshi’s lack of official affiliation with the league.
