Lowest temperature in Chicago on Sep 9, 2026?

Kalshi

All markets resolve based on the minimum temperature recorded in Chicago (CLIMDW) on September 9, 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 Weather Company’s data is the sole authority for resolution. Preliminary data may be subject to rounding or conversion discrepancies, and users should exercise caution when interpreting it. If the Exchange identifies a material error in the initially published data, it may delay expiration until a corrected version is released or until the expiration date, whichever comes first. If no data remains available by the end of this period, all markets will resolve to the last fair price determined by Kalshi.
