Description

This event tracks the highest temperature reached in Chicago on a specific future date, using data from a designated weather authority. It categorizes possible temperature ranges to determine the outcome based on actual recorded conditions.

Kalshi

The event resolves based on the maximum temperature recorded in Chicago (CLIMDW) on August 24, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a specific market outcome. If the temperature falls within a particular range, that market resolves to Yes; all others resolve to No. All outcomes share identical secondary rules emphasizing that The Weather Company’s official report is the sole source for resolution, regardless of other weather services. Participants should exercise caution with preliminary data, as rounding or conversion discrepancies may occur before the final official value is published.
