Highest temperature in Chicago on Oct 19, 2026?

Kalshi

All markets resolve based on the maximum temperature recorded in Chicago (CLIMDW) on October 19, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 64° or below, 65-66°, 67-68°, 69-70°, 71-72°, or above 72°. The official data from The Weather Company is the sole determinant, and users should be aware that preliminary data may differ from final reported values due to rounding or conversion issues. If the Exchange identifies a material error in the initial data publication, it may delay expiration until a corrected version is released or until the expiration date, whichever comes first. In cases where data remains unavailable by the expiration date, markets will resolve to the last fair price determined by Kalshi. The 'Final' status on weather.com/kalshi is informational and does not guarantee data accuracy or exempt markets from potential revisions.
