Description

This event tracks the performance of two baseball teams in an upcoming game, focusing on the margin of victory. It allows participants to speculate on whether a team will win by a specific number of runs or more. 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 single baseball match scheduled for August 18, 2026. Multiple markets exist, each corresponding to a specific run margin outcome—Boston winning by more than 3.5, 2.5, or 1.5 runs, and Arizona winning by more than 1.5, 2.5, or 3.5 runs. Each market resolves to 'Yes' if the specified team achieves the exact run-differential threshold or exceeds it. All markets operate independently; the resolution of one does not affect the others. The governing rules emphasize that the platform bears no official affiliation with the league, and all trademarks remain property of their respective owners.
