This event tracks whether Boston will experience specific temperature ranges on September 18, 2026. Outcomes depend on the exact peak temperature recorded at a designated weather station, with different markets covering various temperature brackets.
All markets resolve based on the maximum temperature recorded at Boston's official weather station (CLIBOS) on September 18, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: 73°F or below, 74-75°F, 76-77°F, 78-79°F, 80-81°F, or above 81°F. The Weather Company serves as the sole source for official data, though users may reference other services for guidance. Preliminary data may contain rounding or conversion discrepancies, requiring caution in interpretation. If the Exchange identifies a material error in the initial data publication, it may delay resolution until a corrected version is released or until the expiration date, whichever comes first. Should no valid data remain available by the expiration date, all markets resolve at the last fair price determined by the Exchange. The 'Final' status on The Weather Company's platform is informational and does not guarantee error-free data.
