This event tracks the lowest temperature recorded in Chicago on a specific date in the future, using official government data. The outcome depends entirely on the exact temperature reading from the National Weather Service's official report for that day.
All markets resolve based solely on the official minimum temperature recorded in Chicago on August 7, 2026, as reported by the National Weather Service's Climatological Report (Daily) for Chicago - Midway, IL. Each market corresponds to a specific temperature range: 61°F or below, 62-63°F, 64-65°F, 66-67°F, 68-69°F, or 70°F and above. The exact temperature value from the official report determines which market resolves to 'Yes,' with all others resolving to 'No.' Traders must reference the official NWS data linked in the rules, as preliminary or third-party data sources are not authoritative. Due to potential rounding and conversion nuances in preliminary NWS data, caution is advised when interpreting early reports. The final report, released after the date in question, will serve as the binding authority for resolution.
