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 meteorological data. The event helps gauge extreme weather expectations for that day.

Kalshi

The event resolves based on the maximum temperature recorded in Chicago (CLIMDW) on September 2, 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 given range, that market resolves to Yes; all others resolve to No. Ranges are structured from lowest (91°F or below) to highest (100°F or above), with incremental bands of 1-2 degree intervals between them. All markets share identical secondary rules emphasizing that The Weather Company’s official report is the sole arbiter, despite potential discrepancies with other weather services. Participants should exercise caution with preliminary readings due to possible rounding or conversion differences before the final data is published.
