Description

This event tracks the lowest 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.

Kalshi

The event resolves based on the minimum temperature recorded at Boston's CLIBOS station on September 10, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market outcome. If the recorded low falls within a specific range, the associated market resolves to 'Yes,' with all others resolving to 'No.' All markets share identical secondary rules regarding data verification and error handling. The Exchange retains discretion to delay resolution if a material error is identified in preliminary data, allowing time for correction or proceeding to the Expiration Date. In cases where data remains unavailable by the deadline, 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 exempt the data from potential revision under these rules.
