Description

This event tracks whether specific temperature thresholds will be met or exceeded in Seattle on a particular date in the future. The outcome depends entirely on official weather data from a designated source, reflecting climate conditions rather than predictions or estimates.

Kalshi

The event determines if the maximum temperature in Seattle on October 20, 2026, falls within any of several defined ranges, with resolution based exclusively on data from The Weather Company. Each market corresponds to a specific temperature range: below 59°F, 59-60°F, 61-62°F, 63-64°F, 65-66°F, or above 66°F. If the recorded high temperature matches the range of a given market, that market resolves to Yes; all others resolve to No. Official data from The Weather Company is the sole authority, and preliminary readings may differ from final values due to rounding or conversion. The exchange retains discretion to delay resolution if a material error is identified in the initial data release, extending the evaluation period until a corrected version is published or the expiration date arrives. Should data remain unavailable by the expiration date, markets resolve at the last fair price determined by the exchange. The "Final" status on The Weather Company’s platform is informational and does not override these resolution protocols.
