Lowest temperature in Chicago on Oct 17, 2026?

Kalshi

All markets resolve based on the minimum temperature recorded at Chicago (CLIMDW) on October 17, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 32° or below, 33-34°, 35-36°, 37-38°, 39-40°, or above 40°. The official data source is The Weather Company, and users should exercise caution with preliminary readings due to potential rounding or conversion differences. If a material error is identified in the initial publication, the Exchange may delay expiration until a corrected revision is released or until the expiration date, whichever comes first. If data remains unavailable by the end of this period, 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 these error-resolution procedures.
