Description

This event tracks the peak temperature in Chicago on a specific summer day in 2026, using official government data. It helps participants assess climate conditions and temperature trends for that exact date, reflecting real-world weather expectations and planning.

Kalshi

The event resolves based on the highest temperature recorded at Chicago Midway International Airport on August 6, 2026, as officially reported by the National Weather Service's Climatological Report (Daily). Six separate temperature ranges define possible outcomes: 75° or below, 76-77°, 78-79°, 80-81°, 82-83°, and 84° or above. The National Weather Service's report is the sole authority for determining the result, and traders must rely on its final published data rather than third-party sources like AccuWeather or Google Weather. Preliminary reports may contain rounding or conversion discrepancies, so caution is advised when interpreting early data. The official report will resolve the market definitively once available.
