Description

This event tracks the highest temperature reached in Washington DC on a specific date in the future. The outcome depends entirely on official weather data from a designated source, reflecting climate conditions for that day.

Kalshi

All markets resolve based on the maximum temperature recorded at Washington DC (CLIDCA) on September 15, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 78°F or below, 79-80°F, 81-82°F, 83-84°F, 85-86°F, or above 86°F. The Weather Company’s data is the sole authority, though preliminary readings may differ from final values due to rounding or conversion. If the Exchange identifies a material error in the initial data before expiration, it may delay resolution until a corrected value is published or until the expiration date. If no data remains available by expiration, markets resolve to the last fair price determined by the Exchange. The "Final" status on The Weather Company’s platform is informational and does not guarantee error-free data.
