Description

This event tracks the lowest temperature recorded in Boston on a specific future date, using data from a designated weather provider. The outcome depends entirely on the exact temperature reading at that location and time, making it a straightforward test of weather forecasting accuracy.

Kalshi

All markets resolve based solely on the minimum temperature recorded at Boston's CLIBOS station on September 24, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 50°F, 50-51°F, 52-53°F, 54-55°F, 56-57°F, or above 57°F. The Weather Company's official reporting serves as the definitive source, even if other services show different values. Preliminary data may be subject to revision, and the Exchange retains discretion to delay resolution if material errors are identified in initial reports. If final data remains unavailable by expiration, markets resolve at the last fair price determined by the Exchange. The "Final" status on The Weather Company's platform is informational only and does not override these resolution procedures.
