Description

This event tracks the highest temperature reached in Boston on a specific date in the future, using data from a designated weather provider. The outcome depends entirely on how warm it gets that day, with different markets covering various temperature ranges.

Kalshi

All markets resolve based on the maximum temperature recorded at Boston's CLIBOS station on October 10, 2026, as reported by The Weather Company. Each market covers a specific temperature range: 60°F or below, 61-62°F, 63-64°F, 65-66°F, 67-68°F, or above 68°F. The Exchange may delay resolution if it identifies material errors in the initial data publication, holding expiration until a corrected version appears or the original expiration date passes. If data remains unavailable by expiration, markets resolve at the last fair price determined by Kalshi. While other weather sources may show different values, The Weather Company's report is the sole authority for all outcomes.
