Highest temperature in Washington DC on Sep 23, 2026?

Kalshi

The event resolves based on the maximum temperature recorded at Washington DC (CLIDCA) on September 23, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market that will resolve to 'Yes' if the recorded temperature falls within that range. All markets share identical secondary rules regarding data verification and error handling. The Weather Company's official reporting serves as the sole arbiter of temperature data. Preliminary readings may be subject to rounding or conversion discrepancies, and participants should exercise caution when interpreting them. If the Exchange identifies a material error in the initial publication, it retains the discretion to extend the expiration period until a corrected revision is published or until the original expiration date passes, whichever occurs first. In cases where no reliable data becomes available by the expiration deadline, all markets will resolve to the last fair price established by Kalshi. The 'Final' status indicated on weather.com/kalshi is strictly informational and does not immunize the data from potential revisions or error corrections under these official rules.
