Kalshi

The event resolves based on the maximum temperature recorded at Boston's official weather station (CLIBOS) on October 18, 2026, as reported by The Weather Company. Six separate temperature ranges are defined, each corresponding to a different market outcome. If the temperature falls within a specific range, that market resolves to Yes; all others resolve to No. All markets share common secondary rules regarding data verification and error handling. Preliminary data may be subject to revision, and the exchange reserves the right to delay resolution if material errors are identified in initial reports. If final data remains unavailable by the expiration date, markets will resolve at the last fair price determined by the exchange. The 'Final' status on The Weather Company's platform is informational only and does not guarantee immunity from data revisions or errors.
