This event tracks the lowest temperature recorded in Chicago on a specific future date, using official government data sources. Participants assess climate conditions and historical trends to predict the night's coldest point. The outcome depends solely on the official National Weather Service report for that day.
All markets resolve based exclusively on the minimum temperature recorded in Chicago on August 10, 2026, as reported by the National Weather Service's Climatological Report (Daily) for Chicago - Midway, IL. Each market corresponds to a specific temperature range: 65° or below, 66-67°, 68-69°, 70-71°, 72-73°, or 74° and above. The official 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 offer guidance, only the NWS report determines resolution. Traders should be aware that NWS data may include rounding and conversion nuances, and reports across cities may update at different frequencies, requiring careful verification of the final reported value.
