Description

This event tracks the lowest temperature recorded in Boston on a specific date in the future, using data from a designated weather service. 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 28, 2026, as reported by The Weather Company. Six distinct temperature ranges are defined, each corresponding to a separate market outcome. If the recorded minimum temperature falls within a specific range, the associated market resolves to 'Yes,' with all others resolving to 'No.' The Weather Company's data is the sole authority for determining resolution, even if other sources report different values. Preliminary data may be subject to revision, and the exchange retains discretion to delay resolution if a material error is identified in the initial publication. If no valid data is available by the expiration date, markets 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 data accuracy or exempt the data from potential revisions.
