Highest temperature in Boston on Sep 10, 2026?

Kalshi

The event determines the outcome based on the maximum temperature recorded in Boston (CLIBOS) on September 10, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market that resolves to 'Yes' if the recorded temperature falls within that specific range. All markets rely exclusively on The Weather Company's data for resolution, with preliminary readings subject to potential revisions. If a material error is identified in the initial data publication, the expiration may be delayed until a corrected version is released or until the expiration date, whichever comes first. If no data remains available by the end of this period, all markets resolve to the last fair price determined by Kalshi. The 'Final' status on weather.com/kalshi is informational and does not guarantee data accuracy or exempt the markets from potential revisions under the stated conditions.
