Lowest temperature in Chicago on Oct 27, 2026?

Kalshi

All markets resolve based on the minimum temperature recorded at Chicago (CLIMDW) on Oct 27, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 44° or below, 45-46°, 47-48°, 49-50°, 51-52°, or 53° and above. The Weather Company’s data is the sole authority for resolution. Preliminary data may be subject to rounding or conversion differences, and users should exercise caution when interpreting it. 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, whichever comes first. If no data remains available by the end of this period, all markets resolve to the last fair price determined by Kalshi. A "Final" status on weather.com/kalshi is provided for convenience but does not guarantee data accuracy or exempt markets from potential revisions under these rules.
