Lowest temperature in Chicago on Sep 4, 2026?

Kalshi

The event resolves based on the minimum temperature recorded in Chicago (CLIMDW) on September 4, 2026, as reported by The Weather Company. Five markets cover specific temperature ranges: 65° or below, 66°-67°, 68°-69°, 70°-71°, 72°-73°, and 74° or above. The official temperature value comes exclusively from The Weather Company, and users should be aware that preliminary data may differ from the final reported value due to rounding or conversion issues. If the Exchange identifies a material error in the initial data publication, it may delay expiration until a corrected version is released or until the expiration date, whichever comes first. If no data remains available by the end of this period, all markets will resolve to the last fair price determined by Kalshi. The "Final" status on weather.com/kalshi is for convenience and does not guarantee data accuracy or exempt the event from these error-resolution procedures.
