Kalshi

Resolution is determined by the highest temperature recorded at Chicago Midway, Illinois on July 22, 2026, as reported in the National Weather Service's Climatological Report (Daily). The temperature is divided into six distinct ranges: 68°F or below, 69–70°F, 71–72°F, 73–74°F, 75–76°F, and 77°F or above. Each range corresponds to a separate market outcome that resolves to Yes if the recorded temperature falls within that range. The NWS Climatological Report (Daily) is the official and final source for temperature determination. While preliminary NWS data and third-party weather services like AccuWeather or Google Weather may provide guidance, traders should note that preliminary reporting and measurement methods may involve rounding and conversion nuances that could affect interpretation of the data.
