Description

This event tracks the highest temperature recorded in Washington DC on a specific date in the future. The outcome depends solely on official weather data from a designated source, making it a straightforward test of climate conditions for that day.

Kalshi

The event resolves based on the maximum temperature recorded at Washington DC (CLIDCA) on October 30, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 72° or below, 73-74°, 75-76°, 77-78°, 79-80°, or above 80°. If the recorded temperature falls within a market's defined range, that market resolves to Yes, with all others resolving to No. The Exchange retains discretion to address material errors in the initial data publication, potentially delaying resolution until a corrected value is available or until the expiration date. If data remains unavailable by the expiration date, markets resolve to the last fair price determined by Kalshi. Preliminary data may differ from final reports due to rounding or conversion, so participants should exercise caution when interpreting early readings. The status of 'Final' on The Weather Company's platform is informational and does not guarantee data accuracy or exempt the event from potential adjustments.
