Description

This event tracks the highest temperature that Boston will experience on a specific date in the future, using data from a designated weather provider. The outcome depends entirely on the official temperature recording for that day, reflecting climate conditions and forecasting challenges.

Kalshi

All markets resolve based on the maximum temperature recorded at Boston’s CLIBOS station on October 23, 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 data is the sole authority, though preliminary readings may differ from final values due to rounding or conversion. If a material error is identified in the initial publication before the market’s expiration, the exchange may delay resolution until a corrected value is released or until the expiration date. If data remains unavailable by the expiration date, all 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 guarantee error-free data.
