Description

This market tracks the lowest temperature recorded in Chicago on July 20, 2026. The outcome will be determined by the official National Weather Service Climatological Report (Daily) for Chicago-Midway Airport, which provides the authoritative minimum temperature measurement for that date.

Kalshi

Resolution is based on the minimum temperature recorded at Chicago-Midway on July 20, 2026, as reported in the National Weather Service's Climatological Report (Daily). The temperature is divided into six ranges: 59°F or below, 60-61°F, 62-63°F, 64-65°F, 66-67°F, and 68°F or above. Each range corresponds to a separate market outcome. The official data source is accessed through the NWS website at the Chicago office, selecting the Observed Weather tab and Chicago-Midway with Daily Climate Report. Traders should note that preliminary NWS data may contain rounding and conversion nuances, and the final official report takes precedence over other weather sources such as AccuWeather or Google Weather.
