Kalshi

All markets resolve based solely on the maximum temperature recorded in Seattle on August 4, 2026, as reported by the National Weather Service's Climatological Report (Daily) for Seattle-Tacoma, WA. Each market corresponds to a distinct temperature range: below 84°F, 84–85°F, 86–87°F, 88–89°F, 90–91°F, or above 91°F. The official data must be accessed via the NWS website, navigating to the 'Observed Weather' tab and selecting the Daily Climate Report for the specified date. Traders should use the latest available report, recognizing that update frequencies may vary across locations. While third-party weather services may offer preliminary or alternative data, they are not authoritative for resolution purposes. Preliminary NWS data may include rounding or conversion nuances, so caution is advised when interpreting early reports. All outcomes depend exclusively on the final, official NWS record.
