Kalshi

The markets collectively determine the outcome based on the run differential in the Arizona vs Boston professional baseball game scheduled for August 19, 2026, at 4:10 PM EDT. If Boston wins by exceeding specific run margins—over 1.5, 2.5, or 3.5 runs—the corresponding Boston markets resolve to Yes. Conversely, if Arizona wins by exceeding thresholds of over 1.5, 2.5, or 3.5 runs, the respective Arizona markets resolve to Yes. All markets share the same secondary disclaimer stating that Kalshi is not affiliated with the governing league, and all trademarks belong to their respective owners. The resolution hinges solely on the official game result and run differential, with no external factors influencing the outcome determination.
