Description

This event tracks the highest temperature reached in Chicago on a specific date in the future, using data from a designated weather authority. It helps participants assess climate conditions and temperature trends for a particular day, reflecting real-world interest in weather forecasting and climate patterns.

Kalshi

The event resolves based on the maximum temperature recorded at Chicago (CLIMDW) on August 31, 2026, as reported by The Weather Company. Six distinct temperature ranges define the possible outcomes, each corresponding to a specific market. If the temperature falls within any of these ranges, the associated market resolves to Yes; otherwise, it resolves to No. All markets share the same data source and methodology, ensuring consistency. Participants should note that preliminary readings may vary due to rounding or conversion differences, and only the final official value from The Weather Company determines the result. Careful interpretation of data is advised, as discrepancies between preliminary and final reports can affect outcomes.
