This event tracks the lowest temperature recorded in Chicago on a specific future date, using official government data sources. Participants assess whether conditions will fall within certain temperature ranges based on verified meteorological reports.
All markets resolve based solely on the official minimum temperature recorded at Chicago - Midway, IL on July 26, 2026, as reported in the National Weather Service's Climatological Report (Daily). Each market corresponds to a specific temperature range: 64°F or below, 65-66°F, 67-68°F, 69-70°F, 71-72°F, or above 72°F. The NWS report is the definitive source, and traders must use the latest version available after the date in question. While preliminary data from other services may provide guidance, only the NWS report determines resolution. Users should be aware that NWS data may include rounding and conversion nuances, requiring careful interpretation of the final reported value to determine which range it falls into.
