Description

This event tracks the highest temperature reached in Seattle on a specific date in 2026. The outcome depends on how warm it gets on that day, with different markets covering various temperature ranges. The official temperature data comes from a designated weather service.

Kalshi

The event resolves based on the maximum temperature recorded in Seattle (CLISEA) on September 4, 2026, as reported by The Weather Company. Six separate markets cover distinct temperature ranges: 65° or below, 66-67°, 68-69°, 70-71°, 72-73°, and 74° or above. If the recorded temperature falls within a specific range, the corresponding market resolves to Yes, with all others resolving to No. Preliminary data may be subject to rounding or conversion differences, and The Exchange retains discretion to address material errors in initial publications. If data remains unavailable by the expiration date, markets resolve to the last fair price determined by Kalshi. The status "Final" on weather.com/kalshi is informational only and does not guarantee data accuracy.
