Description

This event tracks the highest temperature recorded in Chicago on July 19, 2026, using official National Weather Service data from Chicago Midway. Traders predict which temperature range the day will fall into.

Kalshi

Resolution is determined by the highest temperature recorded at Chicago Midway, Illinois on July 19, 2026, as reported in the National Weather Service's Climatological Report (Daily). The temperature is divided into six distinct ranges: 77°F or below, 78–79°F, 80–81°F, 82–83°F, 84–85°F, and 86°F or above. Each range corresponds to a separate market outcome that resolves to Yes if the recorded temperature falls within that range. The official NWS Climatological Report (Daily) is the sole authoritative source for resolution; preliminary NWS data and third-party weather services are not used for final determination. Traders should be aware that preliminary NWS reporting may involve rounding and conversion nuances that could affect interpretation of data before the official report is published.
