Description

This event tracks the highest temperature reached in Chicago on a specific date in the future. It categorizes possible temperature ranges to determine the outcome based on official weather data. The resolution depends solely on the temperature recorded by a designated weather authority.

Kalshi

The event resolves based on the maximum temperature recorded in Chicago (CLIMDW) on August 27, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a different market outcome. If the temperature falls within any of these ranges, the associated market resolves to Yes. All markets use The Weather Company as the exclusive source for temperature data, with preliminary readings subject to potential rounding or conversion differences. Users should exercise caution when interpreting early data, as only the final official value determines the resolution. Consistency across all markets ensures that the same data source and methodology apply uniformly to all temperature assessments.
