Description

This event tracks whether specific temperature thresholds will be reached in Boston on a particular day in the future. The outcome depends entirely on official weather data from a designated source, reflecting climate conditions rather than market predictions.

Kalshi

All markets resolve based on the maximum temperature recorded at Boston's official weather station (CLIBOS) on October 22, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 57°F, 57-58°F, 59-60°F, 61-62°F, 63-64°F, or above 64°F. The Exchange reserves the right to delay resolution if it identifies material errors in preliminary data, extending the evaluation period until a corrected version is published or the expiration date arrives. If data remains unavailable by the expiration date, markets resolve at the last fair price determined by the Exchange. While other weather services may show different values, only The Weather Company's official report determines the outcome.
