Description

This event determines whether specific temperature thresholds will be met in Washington DC on a particular date in the future. The outcome hinges on official weather data from a designated source, reflecting potential climate conditions and variability.

Kalshi

The event evaluates whether the maximum temperature recorded in Washington DC on October 18, 2026, falls within any of several specified ranges, with the Weather Company serving as the sole authority for temperature data. Each market corresponds to a distinct temperature range: below 57°F, 57-58°F, 59-60°F, 61-62°F, 63-64°F, or above 64°F. All markets share identical secondary rules regarding data verification and error handling. Preliminary Weather Company data may undergo revisions, and the exchange retains discretion to delay resolution if material errors are identified in initial reports. If final data remains unavailable by the expiration date, markets resolve based on the last fair price determined by the exchange. The 'Final' status indicated on weather.com/kalshi is informational only and does not guarantee data accuracy or exempt markets from potential adjustments.
