Open Championship 2025 betting odds: Scheffler opens as favorite ahead of McIlroy

Scottie Scheffler (+550) is the opening favorite to win The Open Championship at Royal Portrush, continuing his streak as the favorite in every 2025 major. World No. 2 Rory McIlroy (+750) has significant history at the course, having shot a 61 there as an amateur 20 years ago but also missing the cut during the last Open held there in 2019.

Jon Rahm (12-1) and Bryson DeChambeau (18-1) are positioned as the next tier of contenders. Tommy Fleetwood, Xander Schauffele, Shane Lowry, Ludvig Åberg, and Tyrrell Hatton are all listed at 25-1, while U.S. Open champion J.J. Spaun opens at 90-1.

Betting markets include the lowest tournament round score (Over 63: -180, Under 63: +700, Exactly 63: +210), winning margin (1 stroke: +210, 2 strokes: +330, 3 strokes: +550, 4 or more: +300, Playoff: +375), and whether any golfer will make a hole-in-one (Yes: -120, No: -110).

Odds are also available for each golfer to win, place in the top five, top 10, top 20, or top 40, and to make or miss the cut. Additional markets offer odds for results excluding Scheffler and McIlroy. These odds are current as of publishing time, with ESPN BET referenced for updates.
