Royal Portrush is a beast. Everyone knows it. But as we look at the open odds 2025, the betting markets are reacting to more than just a difficult golf course in Northern Ireland. They’re reacting to a shift in how the modern game is played.
If you watched Shane Lowry romp to victory there in 2019, you remember the rain. You remember the grey skies. You remember the absolute chaos of the final round. Oddsmakers haven't forgotten either. The early prices for the 153rd Open Championship reflect a deep respect for "weather-proof" golfers, guys who can manufacture a flighted 4-iron into a crosswind without blinking.
It’s early. Seriously early. Yet, the money is already moving.
The Big Three and the Portrush Factor
Scottie Scheffler is the favorite. Obviously. He’s the favorite for everything these days, usually sitting somewhere around +500 to +700 depending on which book you're looking at. But the open odds 2025 tell a more nuanced story than just "Scottie is good."
Links golf is the great equalizer. You can be the best ball-striker in the world—which Scottie is—and still get absolutely wrecked by a bad bounce into a pot bunker that hasn't been raked since 1994. The markets are currently hedging. They’re balancing Scheffler's sheer dominance against the specific demands of the Dunluce Links.

Then there’s Rory.
Rory McIlroy and Portrush have a... complicated relationship. He holds the course record (a 61 he shot as a teenager), but he also missed the cut there in 2019 after a disastrous opening 79. The 2025 odds have him tucked right behind Scheffler, usually around +900. It’s a "home game" narrative that drives the price down, even if the statistical reality is a bit more volatile. Is he a value play? Honestly, probably not at that price, but try telling that to the thousands of fans who will be screaming his name across the dunes.
Jon Rahm is the third pillar here. His odds have stabilized after the initial LIV Golf shockwaves cooled down. He’s a monster in the wind. He has the short game to survive the tight lies around the Portrush greens. If you see him anywhere north of +1200, that’s where the professional gamblers start licking their chops.
Why the Numbers Shift So Fast
Betting on golf isn't like betting on the NFL. A quarterback doesn't suddenly forget how to throw a spiral because it’s Tuesday. But a golfer’s "form" can vanish in a week.

The current the open odds 2025 are built on three things:
- Long-term baseline strokes gained data.
- Historical performance on links courses (think St. Andrews, Troon, Hoylake).
- The "Major Championship" pedigree.
But here is what the casual fan misses: the agronomy. Portrush is unique. It’s not as "crispy" as a Muirfield. It’s lusher, greener, and often plays longer than the yardage suggests. The oddsmakers are looking for high-launch, low-spin players who can still control the descent angle.
Keep an eye on Ludvig Åberg. He’s the wildcard. By the time we hit July 2025, his odds might be half of what they are right now. He’s a generational talent who seems completely unfazed by pressure, and the early market is starting to realize that his game translates to any continent, any weather, and any grass type.

In the current landscape of the open odds 2025, you have to look at the Europeans who grew up in this stuff. Tyrrell Hatton. Robert MacIntyre. These guys aren't just "good in the wind"—they thrive in the misery. MacIntyre especially has shown a grit that matches the Portrush ethos perfectly.
Then you have the "Old Guard." Shane Lowry is the king of Portrush. His odds are usually suppressed because of the 2019 win, but he’s still a top-tier links player. If the weather turns foul—and in Northern Ireland, it usually does—Lowry’s value skyrockets. The markets struggle to price in "grit," but you can see it in the way the odds refuse to drop too low for the grinders.
Managing Your Bankroll for July
Don't go all in now. That’s the mistake.
Golf betting is a marathon. The best way to approach the open odds 2025 is to build a "portfolio." You want a heavy hitter (Scheffler/Rahm), a mid-tier specialist (Lowry/Fleetwood), and a couple of "lottery tickets" in the +8000 range.
The wind maps for Portrush are notorious. If the draw is uneven—where the morning wave gets a calm breeze and the afternoon wave gets a 30mph gale—half the field is effectively dead by Friday afternoon. The odds don't reflect that yet because we don't know the tee times.
Actionable Strategy for 2025
- Track the "Links Swing": Watch the results of the Scottish Open the week prior. It’s the best predictor of who has their "links legs" underneath them.
- Ignore the Hype: Rory will be overvalued. He just will. If you’re betting for profit rather than emotion, wait for a drift or look elsewhere.
- Focus on Scrambling: Portrush has massive greens, but if you miss them, you’re dead. Look for players in the top 20 of "Strokes Gained: Around the Green" over the last six months.
- Check the Weather Early: If the forecast looks brutal, start looking at the guys who play on the DP World Tour regularly. They are used to the sideways rain that makes PGA Tour stars fold.
The 153rd Open is going to be a spectacle. The odds will fluctuate wildly as we get through the Masters and the U.S. Open, but the foundation is being laid right now. Keep your eyes on the ball-striking metrics and don't get distracted by the big names if their form is shaky. Portrush doesn't care about your resume; it only cares about your ball flight.
