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 solely 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 8, 2026, as reported by The Weather Company. Five 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.' The Weather Company’s data is the sole authority, and preliminary readings may differ from final values due to rounding or conversion. In cases of material errors in the initial publication, the exchange retains discretion to delay resolution until a corrected value is released or until the expiration date. If data remains unavailable 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 and does not guarantee data accuracy or exempt markets from potential adjustments.
