Highest temperature in Chicago on Sep 4, 2026?

Kalshi

The markets resolve based on the maximum temperature recorded in Chicago (CLIMDW) on September 4, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 88° or below, 89-90°, 91-92°, 93-94°, 95-96°, and 97° or above. If the temperature falls within a market's specified range, that market resolves to Yes; all others resolve to No. 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 is available by the expiration date, all 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 potential revisions.
