Description

This event tracks the peak temperature in Chicago on a specific summer day in 2026. It categorizes possible temperature ranges to determine the outcome based on official weather service data. Participants can speculate on how hot it will get that day.

Kalshi

The event resolves based on the highest temperature recorded at Chicago Midway, IL on August 13, 2026, as reported by the National Weather Service's Climatological Report (Daily). Six distinct temperature bands are defined, each corresponding to a different market outcome. If the recorded temperature falls within a specific range, the associated market resolves to Yes. All markets use the same official data source, and traders must recognize that preliminary reports may contain rounding or conversion nuances, requiring caution in interpretation until the final report is published.
