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 on where the temperature falls within predefined ranges, offering various possibilities for how cold the city will be on that day.
The event determines whether the minimum temperature in Boston on September 6, 2026, as recorded by The Weather Company at the CLIBOS station, falls within one of several specified Fahrenheit ranges. Each range corresponds to a distinct market outcome, from temperatures of 54°F or below up to 63°F or above. The Weather Company serves as the sole source for official temperature data, with all markets resolving based solely on their reported values. Preliminary data may be subject to rounding or conversion discrepancies, and users should exercise caution when interpreting early readings. If the Exchange identifies a material error in the initially published data before the market's expiration, it may delay resolution until a corrected version is released or until the expiration date arrives, whichever occurs first. Should no reliable data remain available by the expiration date, all markets will resolve to their last fair price as determined by Kalshi. The "Final" status indicated on weather.com or kalshi is strictly informational and does not shield the data from potential revisions under these rules.
