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 on that day, with different markets covering various temperature ranges.

Kalshi

All markets resolve based on the maximum temperature recorded at Boston's official weather station (CLIBOS) on September 7, 2026, as reported by The Weather Company. Each market covers a specific temperature range: one for temperatures below 75°F, others for incremental ranges up to 82°F, and a final market for anything above 82°F. The Exchange may delay resolution if it identifies material errors in the initial data publication, extending the evaluation period until either a corrected value is released or the expiration date passes. If data remains unavailable by the expiration date, all markets resolve at the last fair price determined by the Exchange. While other weather sources may show different values, only The Weather Company's official report is used for resolution, and preliminary readings may differ from the final reported value due to rounding or conversion adjustments.
