Open Championship betting odds: Scheffler opens as favorite, McIlroy has second-shortest odds

World No. 1 Scottie Scheffler (+550) continues his streak of opening as the favorite in every golf major in 2025, this time for The Open Championship being held at Royal Portrush in Northern Ireland. The course is very familiar to world No. 2 Rory McIlroy (+750), who shot 61 at the course 20 years ago as an amateur playing the North of Ireland Championship but also struggled and missed the cut in 2019 the last time the Open was held there.

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

The lowest tournament round score has been set at 63, with -180 for over, +700 for under and +210 for exactly 63. Winning margins of 1 (+210), 2 (+330), 3 (+550) or 4 or more (+300) are available, with +375 for the result to require a playoff. Odds for any golfer to make a hole-in-one are -120 for yes and -110 for no.

Below you will find the available odds for each golfer to win, place top five, top 10, top 20 or top 40, as well as to make or miss the cut, and betting odds for results not including Scheffler and McIlroy.
