Description

This event tracks whether specific temperature thresholds will be reached in Washington DC on a particular date, using data from a designated weather provider. Outcomes depend on the exact maximum temperature recorded, with different markets corresponding to various temperature ranges.

Kalshi

All markets resolve based on the maximum temperature recorded at Washington DC (CLIDCA) on September 18, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 82° or below, 83-84°, 85-86°, 87-88°, 89-90°, or above 90° Fahrenheit. The Exchange may delay resolution if a material error is identified in the initial data publication, extending until a corrected revision is published or the expiration date passes. If data remains unavailable by the expiration date, markets resolve to the last fair price determined by the Exchange. Preliminary data may differ from final values due to rounding or conversion, and the 'Final' status on The Weather Company's platform does not guarantee error-free data.
