Description

This event tracks the highest temperature expected in Boston on a specific future date, using data from a designated weather provider. Participants can assess various temperature ranges to predict the outcome based on historical trends and seasonal patterns.

Kalshi

The event resolves based on the maximum temperature recorded at Boston's CLIBOS station on October 24, 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 identical secondary rules regarding data verification and error handling. The Weather Company's official report is the sole source of truth, with preliminary data subject to revision. If a material error is identified before the expiration date, resolution may be delayed until a corrected value is published or until expiration, whichever comes first. In cases where 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 immunity from data revisions or errors.
