This event tracks the highest temperature Seattle will experience on a specific date in 2026. Outcomes depend on how warm the city gets during that single day, with different thresholds defining each possible result.
All markets resolve based solely on the maximum temperature recorded at Seattle (CLISEA) on September 25, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 56°F or below, 57-58°F, 59-60°F, 61-62°F, 63-64°F, or above 64°F. The Exchange may delay resolution if it identifies a material error in the initial data publication, extending the deadline until a corrected value is released or the original expiration date passes. If final data remains unavailable by the expiration date, all markets resolve at the last fair price determined by the Exchange. Preliminary readings may differ from final values due to rounding or conversion adjustments, and the 'Final' status on Weather Company platforms does not guarantee error-free data.
