This event tracks whether Seattle will experience specific temperature ranges on a particular day in 2026. The outcome depends solely on the official weather data recorded at a designated location, with precise thresholds defining success for each temperature band.
All markets resolve based on the maximum temperature recorded at Seattle (CLISEA) on September 9, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 73°F or below, 74-75°F, 76-77°F, 78-79°F, 80-81°F, or above 81°F. The Exchange holds expiration if a material error is identified in preliminary data, resolving markets to the last fair price if no valid data exists by the expiration date. Preliminary readings may differ from final values due to rounding or conversion, and the 'Final' status on weather.com/kalshi does not guarantee error-free data.
