This event tracks the highest temperature reached in Philadelphia on a specific date in the future, using data from a designated weather service. The outcome depends entirely on the official temperature recording for that day, reflecting local climate conditions and measurement standards.
All markets resolve based on the maximum temperature recorded at Philadelphia (CLIPHL) on October 29, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 69°F, 69-70°F, 71-72°F, 73-74°F, 75-76°F, or above 76°F. The Weather Company’s data is the sole authority, though participants may reference other sources for guidance. Preliminary data may be subject to rounding or conversion differences, and the Exchange reserves the right to delay resolution if a material error is identified in the initial publication. If data remains unavailable by the expiration date, markets will resolve to the last fair price determined by Kalshi. The "Final" status on weather.com/kalshi is informational and does not guarantee error-free data.
