Get your hands on a DraftKings promo code for the British Open now!

The best players from around the world will gather at Hoylake for what is expected to be one of the most challenging events of the 2026 season. The last major tournament of the year always captivates audiences, and this year’s British Open is shaping up to be no exception, especially considering the latest odds.

Newcomers, make smart choices with your $5 bet: Golf outrights are known for being difficult to win in North America and can have a long waiting period before results are known. Even though waiting four days can feel like forever, we have some players to keep an eye on to help you through the suspense.

With victories at the Masters and U.S. Open already under his belt, Jon Rahm (+1200) is now looking to capture an Open Championship title. His impressive performance of T3 in 2021 shows that he is a strong contender. Rahm’s well-rounded game makes him one of the most formidable players in the field.

Brooks Koepka is a major force in golf, with five major championships and four runner-up finishes to his name at just 33 years old. He has a strong track record at the British Open, finishing inside the top-10 four times. He is consistently among the pre-event favorites and could be considered the safest outright play of the week.

Dustin Johnson has had ups and downs since winning the 2020 Masters, but he has historically performed well at the Open Championships. With a T4 and a T6 in his previous two British Open appearances and three top-10 results in his last four starts, including a win, this is a favorable price for the former world No. 1 golfer.
