This event tracks the peak temperature in Chicago on a specific summer day in 2026. It categorizes possible temperature ranges to determine the outcome based on official weather service data. Participants can speculate on how hot it will get, with different ranges offering varied levels of likelihood.
The event resolves based on the highest temperature recorded at Chicago Midway, IL on July 30, 2026, as reported by the National Weather Service's Climatological Report (Daily). Six distinct temperature ranges are defined, each corresponding to a specific market outcome. If the recorded temperature falls within a given range, that market resolves to Yes; otherwise, it resolves to No. All outcomes rely exclusively on the official NWS report, and traders should be aware that preliminary data may contain rounding or conversion nuances, making the final NWS report the definitive source. The secondary rule emphasizes that while third-party weather services may offer guidance, they do not determine the market outcome.
