Lowest temperature in Chicago on Sep 15, 2026?

Kalshi

The event resolves based on the minimum temperature recorded in Chicago (CLIMDW) on September 15, 2026, as reported by The Weather Company. Five markets cover specific temperature ranges: 60° or below, 61-62°, 63-64°, 65-66°, 67-68°, and 69° or above. Each market resolves to Yes if the recorded low falls within its respective range. All markets share common secondary rules: The Weather Company’s data is the official source, though users may reference other services for guidance. Preliminary data may differ from final values due to rounding or conversion. If the Exchange identifies a material error in the initial data, expiration may be delayed until a corrected version is published or until the expiration date. If data remains unavailable by the expiration date, markets resolve to the last fair price determined by Kalshi. A “Final” status on The Weather Company’s platform is informational and does not guarantee data accuracy or exempt markets from potential adjustments.
