Lowest temperature in Chicago on Sep 7, 2026?

Kalshi

All markets resolve based on the minimum temperature recorded at Chicago's CLIMDW station on September 7, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 58°F or below, 59-60°F, 61-62°F, 63-64°F, 65-66°F, or 67°F and above. The Weather Company's official report is the sole source for determination, even if other weather services show different values. Preliminary data may be subject to rounding or conversion differences, and readers should exercise caution when interpreting early readings. If the Exchange identifies a material error in the initial non-preliminary publication, it may delay expiration until a corrected version is released or until the expiration date arrives, whichever comes first. Should no data remain available by the expiration period's end, all markets resolve to the last fair price established by Kalshi.
