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 on where the temperature falls within predefined ranges, offering various possibilities for how cold the day might be.

Kalshi

The event resolves based on the minimum temperature recorded in Boston (CLIBOS) on October 19, 2026, as reported by The Weather Company. Five markets cover specific temperature ranges: 35°F or below, 36-37°F, 38-39°F, 40-41°F, 42-43°F, and above 43°F. Each market resolves to Yes if the recorded low falls within its respective range. All markets share identical secondary rules regarding data verification and error handling. Preliminary data may be subject to rounding or conversion differences, and the Exchange reserves the right to delay expiration if a material error is identified in the initial publication. If data remains unavailable by the expiration date, markets will resolve to the last fair price determined by Kalshi. The "Final" status on The Weather Company’s platform is informational only and does not guarantee error-free data.
