The Men’s Open division at the 2025 Mr. Olympia promises one of the most competitive lineups in years. Now we are discussing the 2025 Mr. Olympia Predictions: Men’s Open Top 5. The event runs October 9–12, 2025, in Las Vegas, Nevada, with key events staged at Resorts World Las Vegas and the Las Vegas Convention Center. Veterans and rising stars will collide on bodybuilding’s biggest stage, each bringing their unique blend of muscle, symmetry, and conditioning. Fans have already begun debating who will take home the Sandow trophy.

Samson Dauda comes in as the defending champion, while Derek Lunsford and Hadi Choopan aim to reclaim their past dominance. At the same time, younger athletes like Andrew Jacked and Nick Walker are determined to push the established names aside. The mix of established champions and hungry challengers ensures no easy victories.

This year also carries added intrigue because of the razor-thin margins between physiques. The judges may lean toward aesthetics, conditioning, or pure mass. That unpredictability makes the 2025 Olympia harder to forecast than most.

With that in mind, here’s a breakdown of the five athletes most likely to rise above the rest and secure the top spots on bodybuilding’s most prestigious stage.

2025 Mr. Olympia – Top 5 Athletes Predictions

Samson Dauda

Samson Dauda enters 2025 with the confidence of a reigning Olympia winner. His blend of mass and aesthetics has redefined the modern Men’s Open look. Unlike some competitors who rely solely on size, Dauda presents flowing lines, balanced proportions, and commanding stage presence.

However, his conditioning has often been the point of debate. If Dauda sharpens up just a notch more than last year, his title defense becomes even stronger. He no longer carries the burden of chasing the crown, but instead, the challenge of keeping hungry rivals at bay.

For many fans, Samson represents the future of bodybuilding — a big man who doesn’t sacrifice shape for sheer mass. That evolution makes him the clear frontrunner for another Sandow.

Derek Lunsford

Derek Lunsford has proven himself as one of the most versatile athletes in the sport. After moving up from the 212 division, he quickly became a serious contender in the Open class. His combination of thickness, balanced muscle groups, and sharp conditioning makes him a perennial threat.

What sets Lunsford apart is his relentless drive. Each year, he returns with improvements, never satisfied with near-misses. Heading into 2025, he has been focused on refining his weaker points and ensuring he can match Dauda’s size while maintaining his trademark conditioning.

If Derek nails his peak, he has the tools to topple the defending champion. His rivalry with Samson could define this year’s Olympia.

Hadi Choopan

Hadi Choopan has been one of the most consistent athletes in the world. The former Olympia champion is known for his granite conditioning and dense muscle. Judges and fans alike respect his ability to bring an elite physique year after year.

Though not as tall or structurally wide as some competitors, Hadi makes up for it with detail, maturity, and intensity. He rarely shows weakness on stage and always fights for top placement.

In 2025, Choopan’s challenge will be standing out against taller and fuller physiques. Still, his veteran edge and reliable conditioning could push him back into the top three.

Andrew Jacked – The Dark Horse

Andrew Jacked has been called one of the most genetically gifted bodybuilders of his generation. With broad shoulders, a tiny waist, and towering height, his silhouette immediately commands attention. Fans see him as a future Olympia winner if he can consistently bring world-class conditioning.

In 2025, Andrew’s mission is clear: show the level of detail and hardness that can match his structure. If he nails his prep, he could leapfrog into the top three and surprise many veterans.

For now, he lands in the fourth spot, but the potential for a breakout remains strong. If he peaks perfectly, Andrew could rewrite the script in Las Vegas.

Nick Walker

Nick Walker, known as “The Mutant,” remains one of the most polarizing yet popular bodybuilders today. His insane density, thick muscle bellies, and grainy conditioning make him a dangerous competitor. Fans love his relentless work ethic and no-nonsense approach.

However, Walker has faced challenges with injuries and sometimes struggles with balance and flow compared to more aesthetic rivals. Despite that, his ability to bring freak factor muscle keeps him in the mix every year.

If Walker enters at his best, he can push into the top five comfortably. For many fans, his inclusion keeps the competition electric.

Biggest Threats Outside the Top 5

While the predicted Top 5 appear strongest on paper, the Olympia stage often brings shocks. Brandon Curry, a former Mr. Olympia, still has the tools to break back into the top tier if he shows up with his trademark shape and fullness. His experience and presence cannot be overlooked.

Martin Fitzwater has emerged as one of the fastest-rising athletes in the Open division. His recent wins prove that he can stand next to seasoned champions and hold his own. If he makes even small improvements in detail, he could shake up the top five.

Akim Williams, known for his freakish size and raw power, always remains a wildcard. If his conditioning matches his mass, he could jump into the top group and upset favorites. These names guarantee the lineup will be unpredictable.

Biggest Threats (Roster Table — Outside the Top 5)

Dark Horses Who Could Shock the Olympia

Not every Olympia story comes from the usual favorites. Sometimes a lesser-expected name peaks perfectly and rewrites the outcome. These athletes may not appear in most Top 5 predictions, but their potential, structure, or momentum makes them dangerous dark horses.

For 2025, the dark horse category looks deeper than ever. From newcomers like Marcello “Horse MD” De Angelis to the freak factor of Rubiel “Neckzilla” Mosquera, there are several physiques capable of disrupting the front-runners. Unlike veterans who are judged against their past best, these competitors carry less pressure, giving them freedom to surprise the lineup.

If even one of them nails conditioning while a favorite misses the mark, the ripple effect could shift the entire Top 5. History has shown the Olympia stage rewards perfection on the night of the show, and the door always opens for someone unexpected.

Dark Horse Roster

Marcello De Angelis – The Fan’s Wildcard

Marcello “Horse MD” De Angelis remains one of the most talked-about athletes moving into the Open. Known for his round muscle bellies and aesthetic lines, he brings a look that appeals to both judges and fans. His transition from Classic Physique has kept all eyes on how he stacks against the giants of the Open division.

What makes Marcello a threat is his ability to combine size with pleasing proportions. In a lineup where some physiques appear blocky, his flow can stand out. If he nails his conditioning, his unique structure might carry him higher than many predict.

Crowd support will also play a role. He’s a fan-favorite, and audience energy often enhances a competitor’s stage presence. That could give him the extra edge to surprise.

Rubiel “Neckzilla” Mosquera – The Mass Monster

Rubiel Mosquera has built a reputation as one of the most extreme mass monsters in the sport today. His thick frame, especially in the lower body, gives him an overwhelming presence. At first glance, he looks tailor-made for the Men’s Open division.

The question for Rubiel has always been conditioning. If he can carve out sharper detail while maintaining his insane density, he could leapfrog over athletes with weaker structures. Judges tend to reward balance, but sometimes sheer freak factor wins the crowd — and even the scorecards.

In 2025, Rubiel represents one of the highest-risk, highest-reward competitors. If he’s dialed in, he might shock the Olympia.

Nathan De Asha – The Veteran Dark Horse

Nathan De Asha returns with the hunger to prove he still belongs among the elite. His structure has always been one of his greatest weapons, with crisp lines and wide shoulders that create a commanding silhouette on stage.

Over the years, Nathan has faced ups and downs with injuries and competition schedules. Yet his resilience keeps him relevant. When he’s on, he’s capable of rivaling top names and sliding into Olympia’s upper tier.

This year, Nathan carries both experience and urgency. He knows the window to make a run is narrowing, and that drive could push him into one of the best showings of his career.
