Highest temperature in Chicago on Sep 24, 2026?

Kalshi

The event resolves based on the maximum temperature recorded in Chicago (CLIMDW) on September 24, 2026, as reported by The Weather Company. Six separate markets cover distinct temperature ranges: 65°F or below, 66°F-67°F, 68°F-69°F, 70°F-71°F, 72°F-73°F, and 74°F or above. Each market resolves to Yes if the recorded temperature falls within its specified range. All markets share common secondary rules regarding data verification and error handling. Preliminary data may be subject to rounding or conversion differences, and The Weather Company’s final reported value is the official determinant. If a material error is identified in the initial publication, the Exchange may delay expiration until a corrected value is released or until the expiration date, whichever comes first. If no data remains available by the expiration date, all markets 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.
