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, reflecting possible weather conditions for that day.

Kalshi

All markets resolve based on the minimum temperature recorded at Boston's CLIBOS station on September 3, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 59° or below, 60-61°, 62-63°, 64-65°, 66-67°, or above 67°. The Weather Company’s data is the sole authority, even if other sources report differently. Preliminary data may be subject to rounding or conversion discrepancies, so users should exercise caution. If the Exchange identifies a material error in the initially published data, it may delay resolution until a corrected version is released or until the expiration date, whichever comes first. If data remains unavailable by the expiration date, all markets will resolve to the last fair price determined by Kalshi. The "Final" status on weather.com/kalshi is informational only and does not guarantee data accuracy or exempt markets from potential adjustments.
