Description

This event tracks the peak temperature in Chicago on a specific date, using official government data as the definitive source. Participants assess whether conditions will fall within certain temperature ranges, with precise criteria for resolution based on recorded measurements.

Kalshi

All markets resolve based solely on the highest temperature recorded at Chicago Midway, IL on August 01, 2026, as reported in the National Weather Service's official Climatological Report (Daily). Each market corresponds to a specific temperature range: below 70°F, 70-71°F, 72-73°F, 74-75°F, 76-77°F, or above 77°F. The NWS report serves as the exclusive authority for determining outcomes, and traders must recognize that preliminary data may contain rounding or conversion discrepancies. No alternative weather sources—including commercial services like AccuWeather or public platforms such as Google Weather—carry binding weight in resolution. All decisions hinge on the final, published NWS documentation for that date.
