Description

This event tracks the performance of two baseball teams in an upcoming game, focusing on the margin of victory. It allows participants to assess how decisively one team might outperform the other. The outcome depends entirely on the final score of the game between the two teams.

Kalshi

The event evaluates various run differential thresholds for both teams in a specific professional baseball game scheduled for September 18, 2026. Each market resolves based on whether the winning team exceeds a predetermined run margin—ranging from 1.5 to 3.5 runs—over the opponent. If the stated condition for a given market is met, it resolves to 'Yes'; otherwise, it resolves to 'No'. All markets are independent assessments of different victory margins and are subject to the same game result. Kalshi clarifies that it holds no official affiliation with the governing league, and all associated trademarks remain the property of their respective owners.
