The 2025 Open Championship tees off in the wee hours of Thursday morning at Royal Portrush in County Antrim, Northern Ireland.

The final major of the 2025 season, the Open Championship, features an elite field made up of the best players from the PGA, LIV, and DP World Tours.

Scottie Scheffler is the favorite to win the Claret Jug, one of the two major trophies he doesn’t have on his mantle yet, but the gap between him and Rory McIlroy is razor tight.

Scheffler is +550, which carries a 15.4 percent implied win probability, and McIlroy is +650, which converts to 13.3 percent.

The only other player inside 20/1 at bet365 Sportsbook is Jon Rahm, who is being offered at 12/1.

Bryson DeChambeau (24/1), Shane Lowry (24/1), and defending champion Xander Schauffele (24/1) round out the top of the board.

The British Open is renowned for being one of the most challenging tournaments to predict due to its unique setup and unfamiliar conditions. Played on a links-style course on the windswept isles of the United Kingdom, it takes a specific skillset and temperament to succeed at this event.

In a lot of ways, the conditions level the playing field, as you can’t just show up and overpower a course like Royal Portrush.

That’s why the Open has regularly seen some serious long shots come out on top. Brian Harman (125/1), Shane Lowry (80/1), Zach Johnson (80/1), and Darren Clarke (150/1) have all cashed massive tickets at this event since 2011.

Don’t be surprised to see long shots like Sam Burns (85/1), Keegan Bradley (110/1), Aaron Rai (120/1), and Daniel Berger (140/1) get some considerable betting support at their huge prices.

Bettors also tend to flock to European — especially those from the UK and Ireland — players in this tournament, so don’t be shocked to see a lot of tickets written backing Tommy Fleetwood (27/1), Robert MacIntyre (30/1), Tyrrell Hatton (30/1), and Matt Fitzpatrick (45/1).
