This event tracks the lowest temperature recorded in Chicago on a specific date in the future, using official meteorological data. The outcome depends entirely on the exact temperature reading from a designated weather service for that day.
All markets resolve based solely on the official minimum temperature recorded in Chicago on August 9, 2026, as reported by the National Weather Service's Climatological Report (Daily) for Chicago - Midway, IL. Each market corresponds to a specific temperature range: 60°F or below, 61-62°F, 63-64°F, 65-66°F, 67-68°F, or 69°F and above. The market resolving to 'Yes' is determined by which range the actual recorded minimum temperature falls into. Traders must reference the official NWS data linked in the rules, as preliminary or third-party data sources are not definitive. It is important to note that NWS reports may undergo revisions, and users should use the latest available report for the date in question. Rounding and conversion methodologies inherent in NWS reporting may affect the final outcome, so caution is advised when interpreting early or unofficial data.
