Lowest temperature in Chicago on Oct 20, 2026?

Kalshi

The event resolves based on the minimum temperature recorded in Chicago (CLIMDW) on October 20, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range, and the market associated with the actual recorded minimum temperature will resolve to 'Yes,' with all others resolving to 'No.' All markets share common secondary rules regarding data verification and error handling. Preliminary data may be subject to rounding or conversion differences, and The Weather Company’s final reported value is the official determinant. If the Exchange identifies a material error in the initial publication, the expiration may be delayed until a corrected value is released or until the expiration date. If no data remains available by the expiration date, all markets will resolve to the last fair price determined by Kalshi. The 'Final' status on The Weather Company’s platform is for convenience and does not guarantee data accuracy or exempt the market from these error-resolution procedures.
