Description

This event tracks the highest temperature reached in Seattle on a specific date in the future, using data from a designated weather provider. The outcome depends on where the temperature falls within predefined ranges, reflecting different levels of warmth on that day.

Kalshi

All markets resolve based on the maximum temperature recorded at Seattle (CLISEA) on September 3, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 62°F or below, 63-64°F, 65-66°F, 67-68°F, 69-70°F, or above 70°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 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.
