Highest temperature in Chicago on Oct 12, 2026?

Kalshi

All markets resolve based on the maximum temperature recorded at Chicago (CLIMDW) on October 12, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 84°F, 84–85°F, 86–87°F, 88–89°F, 90–91°F, or above 91°F. The official data from The Weather Company is the sole determinant, and users should exercise caution with preliminary readings due to potential rounding or conversion differences. If the Exchange identifies a material error in the initial data publication, it may delay resolution until a corrected version is released or until the expiration date. If data remains unavailable by the expiration date, markets will resolve to the last fair price determined by Kalshi. The "Final" status on The Weather Company’s platform is informational and does not guarantee error-free data.
