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 the official temperature recording for that day, reflecting climate conditions and forecasting challenges.

Kalshi

The event resolves based on the maximum temperature recorded in Boston (CLIBOS) on September 13, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market that will resolve to 'Yes' if the recorded high falls within its specified range. All markets share identical secondary rules regarding data verification and error handling. Preliminary data may be subject to rounding or conversion discrepancies, and the Exchange reserves the right to delay resolution if a material error is identified in the initial publication. If final data remains unavailable by the expiration date, markets will resolve to the last fair price determined by the Exchange. The 'Final' status on The Weather Company’s platform is informational only and does not guarantee error-free data.
