Highest temperature in Boston on Sep 15, 2026?

Kalshi

The event resolves based on the maximum temperature recorded at Boston's official weather station (CLIBOS) on September 15, 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. If The Weather Company reports a material error in its initial data before the expiration date, the resolution may be delayed until a corrected value is published or until the expiration date arrives, whichever comes first. If no valid data remains available by the expiration date, all markets 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 data accuracy or exempt the data from potential revision under these rules.
