Description

This event tracks whether Boston will experience specific temperature ranges on October 28, 2026. Outcomes depend on the exact peak temperature recorded at a designated weather station, with different markets covering various temperature bands.

Kalshi

All markets resolve based on the maximum temperature recorded at Boston's official weather station (CLIBOS) on October 28, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 54°F, 54-55°F, 56-57°F, 58-59°F, 60-61°F, or above 61°F. The Exchange may delay resolution if it identifies material errors in preliminary data, extending until a corrected value is published or the expiration date arrives. If 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 and does not override these resolution procedures.
