Description

This event tracks the peak temperature in Philadelphia on a specific summer day in 2026. The outcome depends on how hot it gets, with different ranges determining the result. Official data from the National Weather Service will be the sole source for verification.

Kalshi

The event resolves based on the highest temperature recorded at Philadelphia International Airport on July 26, 2026, as officially reported by the National Weather Service's Climatological Report (Daily). Six distinct temperature ranges are defined, each corresponding to a 'Yes' outcome if the recorded high falls within that range. The first five rules cover specific degree ranges from 83°F or below up to 90-91°F, while the final rule captures any temperature above 91°F. All markets share identical secondary rules emphasizing that preliminary or third-party weather data sources are irrelevant; only the official NWS report determines the outcome. Traders must recognize that NWS data may include rounding or conversion nuances in early reports, requiring caution until the final report is published.
