This event tracks the highest temperature reached in Chicago on a specific date, using official government data as the definitive source. It helps participants assess climate conditions and potential impacts on daily life and infrastructure based on temperature thresholds.
The event resolves based on the highest temperature recorded at Chicago Midway, IL on July 31, 2026, as officially reported by the National Weather Service's Climatological Report (Daily). Six distinct temperature ranges are defined, each corresponding to a separate market outcome. If the recorded temperature falls within any of these specified ranges, the associated market resolves to Yes. All outcomes rely exclusively on the NWS report for final determination, with traders advised to be cautious about preliminary data due to potential rounding or conversion nuances in reporting methods. The use of alternative weather sources such as AccuWeather or Google Weather is discouraged for settlement purposes, as they may not align with the official NWS data.
