Lowest temperature in Chicago on Oct 9, 2026?

Kalshi

All markets resolve based on the minimum temperature recorded in Chicago (CLIMDW) on October 9, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 46°F, 46–47°F, 48–49°F, 50–51°F, 52–53°F, or above 53°F. The Weather Company’s official reporting serves as the sole arbiter, even if other services show different values. Preliminary data may contain rounding or conversion discrepancies, so users should exercise caution. If the Exchange identifies a material error in the initial publication before the market’s expiration, it may delay resolution until a corrected value is released or until the expiration date arrives, whichever occurs first. Should no valid data exist at expiration, markets resolve to the last fair price determined by the Exchange. The “Final” status on The Weather Company’s platform is informational only and does not shield the data from potential revisions under these rules.
