Lowest temperature in Chicago on Oct 28, 2026?

Kalshi

The event resolves based on the minimum temperature recorded in Chicago (CLIMDW) on October 28, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 48° or below, 49-50°, 51-52°, 53-54°, 55-56°, or 57° and above. The official temperature value comes exclusively from The Weather Company, and users should be aware that preliminary data may differ from the final reported value due to rounding or conversion issues. If the Exchange identifies a material error in the initial data 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 will resolve to the last fair price determined by Kalshi. The "Final" status on weather.com/kalshi is informational and does not guarantee data accuracy or exempt the event from these error-resolution procedures.
