Description

This event tracks the lowest temperature recorded in Chicago on a specific date in the future, helping participants gauge extreme weather conditions for that day. The outcome depends solely on official weather data from a designated source, ensuring consistency in evaluation.

Kalshi

The event resolves based on the minimum temperature recorded in Chicago (CLIMDW) on August 20, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 59° or below, 60-61°, 62-63°, 64-65°, 66-67°, or 68° and above. If the recorded minimum temperature falls within a market's defined range, that market resolves to Yes; otherwise, it resolves to No. All markets share the same data source and evaluation methodology, with The Weather Company providing the official and final temperature value. This approach ensures uniform assessment across all outcomes, despite potential variations in other weather data sources.
