This event tracks the highest temperature recorded in Washington DC on a specific date in the future. The outcome depends entirely on official weather data from a designated source, making it a straightforward test of actual climate conditions on that day.
The event resolves based on the maximum temperature recorded at Washington DC (CLIDCA) on October 20, 2026, as reported by The Weather Company. Six separate markets cover different temperature ranges: 66° or below, 67-68°, 69-70°, 71-72°, 73-74°, and 75° or above. If the recorded temperature falls within a specific range, the corresponding market resolves to Yes, with all others resolving 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 Exchange reserves the right to delay expiration if a material error is identified in the initial publication. If data remains unavailable by the expiration date, all markets will resolve to the last fair price determined by Kalshi. The status of 'Final' on weather.com/kalshi is informational only and does not guarantee data accuracy or exempt the market from these procedures.
