This event tracks the peak temperature in Chicago on a specific summer day in 2026, using official government data as the definitive source. It categorizes possible temperature ranges to determine the outcome, ensuring transparency and reliability through standardized meteorological reporting.
The event resolves based on the highest temperature recorded at Chicago Midway, IL on July 29, 2026, as officially reported by the National Weather Service's Climatological Report (Daily). Six distinct temperature ranges are defined, each corresponding to a specific market outcome. If the temperature falls within a given range, that market resolves to Yes; all others resolve to No. All outcomes share the same verification source and methodology, with the NWS report serving as the final arbiter. Traders must recognize that preliminary data may undergo revisions, and only the official NWS report should be used for resolution. Rounding and conversion nuances in preliminary reports could affect interpretations, so caution is advised until the official report is published.
