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 21, 2026, as reported by The Weather Company. Six separate temperature ranges are defined, each corresponding to a different market outcome. If the recorded minimum temperature falls within any of these specified ranges, the associated market resolves to 'Yes.' All markets are evaluated using the same official data source, with provisions for handling preliminary data, potential errors, and unresolved data scenarios. In cases of material errors or unavailable data by the expiration date, the markets may resolve based on the last fair price determined by the exchange. The 'Final' status on The Weather Company's platform does not guarantee immunity from data revisions or errors.
