This event tracks the lowest temperature recorded in Boston on a specific future date, using data from a designated weather provider. The outcome depends on where the minimum temperature falls within predefined numerical ranges.
All markets resolve based on the minimum temperature recorded at Boston's CLIBOS station on October 24, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 30°F or below, 31-32°F, 33-34°F, 35-36°F, 37-38°F, or above 38°F. The Exchange holds expiration if it identifies a material error in the initial data publication, extending it until a corrected version is released or the original expiration date passes—whichever comes first. If data remains unavailable by the expiration deadline, all markets resolve to the last fair price determined by Kalshi. Preliminary readings may differ from final values due to rounding or conversion, and the 'Final' status on weather.com/kalshi is informational only and does not guarantee error-free data.
