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 4, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 62°F or below, 63-64°F, 65-66°F, 67-68°F, 69-70°F, or above 70°F. The Weather Company's data is the sole authority, and preliminary readings may differ from final values due to rounding or conversion. If a material error is identified in the initial publication, the exchange may delay resolution until a corrected value is released or until the expiration date. If no data remains 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 and does not guarantee data accuracy or exempt markets from potential revisions.
