What Are U.S. Open 2026 Prediction Markets?
DuelDuck opens U.S. Open golf community duels at 50/50 for every round and player outcome, from outright winner to cut-line drama, regardless of Kalshi or sportsbook consensus.
The 2026 U.S. Open runs June 18-21 at Shinnecock Hills Golf Club, Southampton, New York. On NBC and Peacock. Sixth U.S. Open at Shinnecock since 2018.
Scottie Scheffler leads at +490 FanDuel and 15% on Kalshi. Rory McIlroy is +950 after winning the 2026 Masters. A Rory win completes the career grand slam. J.J. Spaun is the defending champion from 2025 Oakmont.

Shinnecock Hills: What Makes This Course Different
Wind: Shinnecock Hills sits on Long Island Sound and produces extreme wind exposure. A 20mph swing between Thursday and Sunday can create 10-stroke scoring differentials.
Greens speed: USGA setup can make the course unplayable if greens run above 14 on the Stimpmeter in afternoon winds. A setup controversy is a live prediction market event in its own right.
Morning/afternoon draw split: Historically worth 3-5 strokes at Shinnecock. Participants who identify which top contenders have morning tee times on Thursday and Friday have a first-round positioning edge.
