Description

This event tracks the lowest temperature recorded in Washington DC 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.

Kalshi

All markets resolve based on the minimum temperature recorded at Washington DC (CLIDCA) on September 18, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 66°F or below, 67-68°F, 69-70°F, 71-72°F, 73-74°F, or 75°F and above. The official data source is The Weather Company, and preliminary readings may differ from final values due to rounding or conversion. If a material error is identified in the initial publication, the Exchange may delay resolution until a corrected value is released or until the expiration date. If data remains unavailable by the expiration date, markets will resolve to the last fair price determined by Kalshi. The 'Final' status on weather.com/kalshi is informational and does not guarantee data accuracy.
