This market will resolve according to the listed nationality of the 2026 US Open champion. In the event of a tie, this market will resolve in favor of the nationality of the player whose listed last name comes first alphabetically. If the 2026 US Open at Shinnecock Hills Golf Club is cancelled, postponed after July 5, 2026, 11:59 PM ET, or if a champion has not been declared within that timeframe, this market will resolve to "Other". The primary resolution source will be the official results published by the US Open website.
