Highest temperature in Chicago on Sep 10, 2026?

Kalshi

All markets resolve based on the maximum temperature recorded at Chicago (CLIMDW) on September 10, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 74°F or below, 75-76°F, 77-78°F, 79-80°F, 81-82°F, or above 82°F. The Weather Company's official report is the sole source for determination, even if other services show different values. Preliminary data may be subject to rounding or conversion differences, so users should exercise caution. If the Exchange identifies a material error in the initial non-preliminary data, it may delay expiration until a corrected version is published or until the expiration date, whichever comes first. If data remains unavailable by the expiration date, all markets will resolve to the last fair price determined by Kalshi. The "Final" status on weather.com/kalshi is for convenience and does not guarantee data accuracy or exempt markets from potential revisions.
