Description

This event tracks the highest temperature reached in Philadelphia on a specific date in the future, using an authoritative weather data provider. The outcome depends entirely on how warm it gets that day, with different ranges determining the result.

Kalshi

The event resolves based on the maximum temperature recorded at Philadelphia (CLIPHL) on August 25, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a different market outcome. If the temperature falls within any of these ranges, the associated market resolves to Yes. All markets use the same data source and methodology, with the Weather Company's final reported value serving as the official determinant. Users should note that preliminary readings may vary due to rounding or conversion differences, and only the finalized data from The Weather Company will be used for resolution. The secondary rules emphasize reliance on the official source over other weather services for verification.
