Scottie Scheffler holds the top spot in Open Championship betting odds as the 2026 field takes shape, with bookmakers favoring the reigning PGA Champion to defend his title at Royal Troon. The American’s dominance in recent majors keeps him ahead of rivals like Rory McIlroy and Jon Rahm, though a few surprises lurk in the lower ranks of the top 10.**

**Why Is Scheffler the Favorite?** Scheffler’s **2025 PGA Championship win** and consistent form in 2026 have cemented his status as the man to beat. His ability to close out tournaments under pressure—including a wire-to-wire victory at Kiawah Island—has bookmakers pricing him at **lower odds than any other player** entering the Open. But can he replicate that success on the links of Royal Troon, where the wind and undulating greens favor a different style?

**Who’s in the Top 10—and Why?** Behind Scheffler, **Rory McIlroy (2/5) and Jon Rahm (3/1)** sit as the next best bets, with both having recent Open experience. McIlroy, the 2022 champion, is targeting a third Claret Jug, while Rahm’s **2023 Masters win** suggests he’s a major threat. Further down, **Collin Morikawa (5/1), Viktor Hovland (6/1), and Xander Schauffele (7/1)** round out the top five, each with recent major success or strong 2026 form.

**The Dark Horses: Who Could Upset the Odds?** The lower half of the top 10 includes **Scottie’s fellow Americans like Jordan Spieth (10/1)**, who’s been in resurgent form, and **Ludvig Åberg (12/1)**, the young Swede who’s climbed the rankings rapidly. Even **Tom Kim (15/1)**—a 2025 Masters runner-up—could make noise if he continues his recent momentum. But with Scheffler’s **consistency and recent wins**, the underdogs face an uphill battle.

**What’s Next for Scheffler Before the Open?** Scheffler has **one more tournament before the Open Championship**, the **2026 Irish Open at Royal Portrush**, where he’ll test his form against Europe’s best. A strong showing there could further solidify his betting advantage. Meanwhile, rivals like McIlroy and Rahm will use the **British Open series** to fine-tune their games ahead of the major. With **Royal Troon hosting the event from July 18–21**, the stage is set for a clash of styles—and Scheffler’s title defense begins now.
