Description

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 on where the temperature falls within predefined ranges, reflecting potential weather conditions for that day.

Kalshi

The event resolves based on the maximum temperature recorded at Boston's CLIBOS station on October 12, 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 temperature falls within that range. All markets share common secondary rules regarding data verification and error handling. If The Weather Company publishes preliminary data that later proves materially erroneous, the Exchange may delay resolution until a corrected value is released or until the expiration date, whichever comes first. Should no reliable data remain available by the expiration date, all markets resolve to the last fair price determined by Kalshi. The 'Final' status on The Weather Company's platform is informational only and does not guarantee data accuracy or exempt the event from these error-resolution procedures.
