This set of markets focuses on predicting Boston's lowest temperature on a specific date in the future. Outcomes depend entirely on official weather data from a designated source, reflecting interest in climate patterns and seasonal variations.
All markets resolve based on the minimum temperature recorded at Boston's CLIBOS station on October 4, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 46°F, 46–47°F, 48–49°F, 50–51°F, 52–53°F, or above 53°F. The Weather Company’s data is the sole authority, even if other services show different values. Preliminary readings may vary due to rounding or conversion issues, so users should exercise caution. If the Exchange identifies a material error in the initially published data, it may delay resolution until a corrected version is released or until the market’s expiration date. Should no data remain available by then, markets will settle at the last fair price determined by the Exchange. The “Final” status on The Weather Company’s platform is informational only and does not shield the data from potential revisions under these rules.
