Kalshi

All markets resolve based solely on the maximum temperature recorded in Seattle on July 23, 2026, as reported by the National Weather Service's Climatological Report (Daily) for Seattle-Tacoma, WA. Each market corresponds to a specific temperature range: 75°F or below, 76-77°F, 78-79°F, 80-81°F, 82-83°F, or above 83°F. The official NWS report is the definitive source, and traders must use the latest version available after the date in question. While third-party weather services may offer preliminary or estimated data, they are not authoritative for resolution purposes. Traders should be aware that NWS data may include rounding or conversion nuances, and provisional reports can change before final publication. All disputes regarding temperature values will be settled exclusively using the NWS Climatological Report (Daily) data linked in the event rules.
