If Scottie Scheffler, Rory McIlroy, and Bryson DeChambeau combine to win more major tournaments than Jannik Sinner in 2026, then the market resolves to Yes. A major tournament is defined by the sport’s governing bodies. Tennis majors: Australian Open, French Open, Wimbledon, and U.S. Open. Golf majors: The Masters, U.S. Open, The Open Championship (British Open), and PGA Championship. For this market, only victories in the tournaments listed above will count as major tournament wins. For tennis, only Singles titles are counted — Doubles titles will not count toward the total. This market will close and expire after a winner is declared.
