Description

This event tracks the peak temperature in Philadelphia on a specific summer day in 2026. It categorizes possible temperature outcomes into distinct ranges, each representing a different market outcome. The final determination relies on official data from the National Weather Service to ensure accuracy and consistency.

Kalshi

The event resolves based on the highest temperature recorded at Philadelphia International Airport on July 24, 2026, as officially reported by the National Weather Service's Climatological Report (Daily). Six distinct temperature ranges are defined, each corresponding to a specific market outcome. If the recorded temperature falls within the 81° or below range, the '81° or below' market resolves to Yes. If it falls between 82°-83°, the '82° to 83°' market resolves to Yes, and this pattern continues for the ranges 84°-85°, 86°-87°, and 88°-89°. For any temperature above 89°, the '90° or above' market resolves to Yes. The National Weather Service's report is the sole authority for determining the outcome, and traders should be aware that preliminary data may undergo revisions due to rounding or conversion nuances. All secondary rules emphasize the importance of using the official NWS data over other weather sources for final resolution.
