This set of markets assesses the likelihood of specific temperature ranges in Boston on a particular date in the future. Participants can speculate on whether the lowest temperature recorded will fall within certain degree boundaries, based on official weather data from a designated source.
All markets resolve based on the minimum temperature recorded at Boston's CLIBOS station on October 11, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 41°F, 41-42°F, 43-44°F, 45-46°F, 47-48°F, or above 48°F. The Weather Company’s data is the sole authority for resolution. Preliminary data may be subject to rounding or conversion discrepancies, so users should exercise caution. If the Exchange identifies a material error in the initial publication, it may delay expiration until a corrected version is released or until the expiration date, whichever comes first. If data remains unavailable by the expiration date, all markets resolve to the last fair price determined by Kalshi. The "Final" status on The Weather Company’s platform is informational and does not guarantee error-free data.
