This event tracks the highest temperature recorded in Boston on a specific date in the future, using data from a designated weather provider. The outcome depends entirely on the official temperature reading reported by The Weather Company for that day.
The event resolves based on the maximum temperature recorded at Boston's official weather station (CLIBOS) on October 3, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market outcome. If the temperature falls within a specific range, the associated 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 resolve based on the last fair price determined by the Exchange. The status of 'Final' on The Weather Company's platform is informational only and does not guarantee immunity from revisions or errors.
