Lowest temperature in Chicago on Oct 21, 2026?

Kalshi

The event determines the outcome based on the minimum temperature recorded in Chicago (CLIMDW) on October 21, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range, and the market resolving to 'Yes' is the one that encompasses the actual recorded minimum temperature. All markets share identical secondary rules regarding data verification and error handling. If a material error is identified in the initial publication, the expiration may be delayed until a corrected value is released or until the expiration date, whichever comes first. If no data is available by the end of this period, all markets resolve to the last fair price determined by Kalshi. The 'Final' status on The Weather Company's platform is informational and does not guarantee data accuracy or exempt the event from these resolution procedures.
