Description

This event tracks the peak temperature in Philadelphia on a specific summer day in 2026, using official government data as the definitive source. It divides possible temperature outcomes into distinct ranges to determine the result.

Kalshi

All markets resolve based solely on the highest temperature recorded at Philadelphia International Airport on July 27, 2026, as officially reported by the National Weather Service's Climatological Report (Daily). The temperature must fall within one of six predefined ranges: less than 83°F, 83-84°F, 85-86°F, 87-88°F, 89-90°F, or above 90°F. Each range corresponds to a separate market that will resolve to 'Yes' if the actual temperature falls within that specific band. The NWS report is the exclusive authority for determining the outcome, and traders should be aware that preliminary data from other services may differ due to rounding or conversion differences. All markets are evaluated against the same temperature measurement, with only one market resolving to 'Yes' depending on where the recorded high falls within the defined ranges.
