This event tracks the highest temperature recorded in Philadelphia on July 12, 2026, using official National Weather Service data from Philadelphia International Airport. Traders predict which temperature range the day will fall into.
Resolution is determined by the highest temperature recorded at Philadelphia International Airport on July 12, 2026, as reported in the National Weather Service's Climatological Report (Daily). The temperature is divided into six ranges: 83°F or below, 84–85°F, 86–87°F, 88–89°F, 90–91°F, and 92°F or above. Each range corresponds to a separate market outcome that resolves to Yes if the official NWS reading falls within that band. The official NWS Climatological Report (Daily) is the authoritative source for resolution; preliminary NWS data and third-party weather services such as AccuWeather or Google Weather may differ due to rounding and measurement methodology variations and should not be used as the final reference.
