Highest temperature in Chicago on Oct 21, 2026?

Kalshi

These markets resolve based on the maximum temperature recorded in Chicago (CLIMDW) on October 21, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 67°F or below, 68–69°F, 70–71°F, 72–73°F, 74–75°F, or above 75°F. The official data from The Weather Company is the sole determinant, and users should be aware that preliminary readings may differ from final reported values due to rounding or conversion discrepancies. 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, whichever comes first. If no data remains available by the expiration date, markets will 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 guarantee error-free data.
