This event monitors the lowest temperature in Seattle on August 18, 2026, with outcomes determined by The Weather Company’s data. Specific temperature ranges dictate which market resolves, offering a precise measure of that day’s climate conditions.
The market resolves based on the minimum temperature recorded at Seattle (CLISEA) on August 18, 2026, as reported by The Weather Company. Six separate temperature ranges are defined, each corresponding to a different market outcome. If the minimum temperature is 51°F or below, the first market resolves to Yes. If it is between 52°F and 53°F, the second market resolves to Yes, and this pattern continues for subsequent ranges up to 58°F to 59°F. For temperatures of 60°F or above, the final market resolves to Yes. The Weather Company’s data is the sole authority for determining the outcome, and all participants must rely on this source for accuracy.
