Highest temperature in Chicago on Oct 8, 2026?

Kalshi

The event resolves based on the maximum temperature recorded in Chicago (CLIMDW) on October 8, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market outcome. If the temperature falls within a specified range, the associated market resolves to 'Yes,' while all others resolve to 'No.' The Weather Company serves as the sole source for official temperature data. Participants should exercise caution with preliminary readings due to potential rounding or conversion discrepancies. In cases where the Exchange identifies a material error in the initial data publication, the expiration may be delayed until a corrected value is released or until the expiration date, whichever occurs first. If data remains unavailable by the expiration date, all markets will resolve to the last fair price determined by Kalshi. The 'Final' status on weather.com/kalshi is provided for convenience but does not guarantee data accuracy or exempt the market from these resolution procedures.
