Description

This set of markets focuses on predicting Boston's weather conditions for a specific date in the future. Participants assess the likelihood of different temperature ranges being reached during that day, based on official meteorological data.

Kalshi

All markets resolve based on the maximum temperature recorded at Boston's official weather station (CLIBOS) on October 29, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 63°F, 63-64°F, 65-66°F, 67-68°F, 69-70°F, or above 70°F. The Weather Company's data is the sole authority for resolution, though participants are advised that preliminary readings may differ from final values due to rounding or conversion issues. If the Exchange identifies a material error in the initial data release, it may delay resolution until corrected data is published or until the market's expiration date. In cases where data remains unavailable by the expiration deadline, markets will 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 guarantee error-free data.
