Highest temperature in Washington DC on Sep 21, 2026?

Kalshi

The event resolves based on the maximum temperature recorded at Washington DC (CLIDCA) on September 21, 2026, as reported by The Weather Company. Six separate markets correspond to different temperature ranges: below 71°F, 71-72°F, 73-74°F, 75-76°F, 77-78°F, and above 78°F. Each market resolves to Yes if the actual temperature falls within its specified range. All markets share identical secondary rules regarding data verification and error handling. Preliminary Weather Company data may be subject to rounding or conversion differences, so participants should exercise caution when interpreting early readings. If the Exchange identifies a material error in the initially published data, it may delay expiration until a corrected version is released or until the expiration date itself, whichever comes first. If no reliable data remains available by the expiration date, all markets will resolve to the last fair price determined by Kalshi. The "Final" status on weather.com/kalshi is strictly informational and does not guarantee data accuracy or exempt the event from these error-resolution procedures.
