Highest temperature in Washington DC on Sep 28, 2026?

Kalshi

The event resolves based on the maximum temperature recorded at Washington DC (CLIDCA) on September 28, 2026, as reported by The Weather Company. Six separate temperature ranges are defined, each corresponding to a different market outcome. If the temperature falls within a specific range, that market resolves to Yes; all others resolve to No. All markets share identical secondary rules regarding data verification and error handling. Preliminary data may be subject to rounding or conversion differences, and The Weather Company’s final reported value is the official determinant. If a material error is identified in the initial publication before the expiration date, the resolution may be delayed until a corrected value is published or until the expiration date arrives. If no valid data exists at expiration, all markets resolve to the last fair price determined by the exchange. The “Final” status on The Weather Company’s platform is informational only and does not guarantee data accuracy or exempt the event from these error-resolution procedures.
