Description

This event tracks the highest temperature recorded at Chicago Midway, Illinois on July 21, 2026. The outcome will be determined by the National Weather Service's official Climatological Report (Daily) for that date, with temperature ranges spanning from 83°F or below up to 92°F or above.

Kalshi

Resolution is based on the highest temperature recorded at Chicago Midway, Illinois on July 21, 2026, as reported in the National Weather Service's Climatological Report (Daily). The temperature is divided into six distinct ranges: 83°F or below, 84-85°F, 86-87°F, 88-89°F, 90-91°F, and 92°F or above. Each range corresponds to a separate market outcome that resolves to Yes if the official NWS reading falls within that range. The official NWS Climatological Report (Daily) is the authoritative source for resolution; preliminary NWS data and alternative weather services such as AccuWeather or Google Weather may be consulted for guidance but are not binding. Traders should be aware that preliminary NWS reporting and measurement methods may involve rounding and conversion nuances that could affect interpretation of borderline values.
