This event tracks the expected minimum temperature in Philadelphia on a specific future date, helping participants assess climate conditions for planning or risk management purposes. The outcome depends solely on official weather data from a designated source.
All markets resolve based on the minimum temperature recorded at Philadelphia (CLIPHL) on September 26, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 51°F or below, 52°F to 53°F, 54°F to 55°F, 56°F to 57°F, 58°F to 59°F, or 60°F and above. The Exchange holds expiration if a material error is identified in preliminary data, resolving markets to the last fair price if no valid data becomes available by the expiration date. Preliminary readings may differ from final values due to rounding or conversion, and the "Final" status on weather.com/kalshi is informational only.
