This event tracks the lowest temperature recorded in Chicago on a specific date, using official weather service data. Participants assess where the temperature will fall within defined ranges, with outcomes determined by verified meteorological reports.
All markets resolve based on the official minimum temperature recorded in Chicago on July 30, 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 resolves to Yes if the recorded minimum temperature falls within the specified range for that market. Traders must rely exclusively on the official NWS data linked in the rules, as preliminary or third-party weather data may differ due to rounding, conversion, or reporting nuances. It is crucial to use the latest version of the NWS report for the date in question, noting that update frequencies can vary. Caution is advised when interpreting preliminary data, as official values may be subject to adjustment.
