Description

This event tracks the lowest temperature recorded in Boston on a specific date in the future, using data from a designated weather provider. The outcome depends entirely on the official temperature reading reported by The Weather Company for that day.

Kalshi

All markets resolve based on the minimum temperature recorded at Boston's CLIBOS station on September 25, 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 no valid data exists at expiration, markets resolve to 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.
