Hafthor Júlíus Björnsson (born 26 November 1988, Reykjavík, Iceland) is an actor, producer, and legendary strongman whose colossal 6′9″ (2.06 m) frame and calm charisma have made him a pop‑culture icon. After a knee injury ended his pro‑basketball career at eighteen, he redirected his competitive fire to strength sports, winning Europe’s Strongest Man three times and capturing the coveted 2018 World’s Strongest Man crown. Björnsson cemented his power‑lifting legacy in May 2020 by dead‑lifting a record‑breaking 501 kg (1,104 lb) on live TV, then pivoted to heavyweight boxing, defeating rival Eddie Hall in “The Heaviest Boxing Match in History” (2022).
On‑screen, audiences know him as Ser Gregor “The Mountain” Clegane in HBO’s Emmy‑winning epic Game of Thrones (seasons 4–8), where his silent menace became instantly meme‑worthy. Additional credits include actioner Kickboxer: Retaliation (2018) and voice work in The Northman (2022). Off camera, Björnsson co‑owns Iceland’s Thor’s Power Gym, endorses nutrition brands, and, with wife Kelsey Henson, champions mental‑health and fitness causes across social media.

School / College / University
He began his academic path at Grundaskóli and continued to Hjallaskóli, where his towering frame and boundless energy already made him stand out.
Later, he enrolled in the polytechnic school in Breiðholt, Iceland, balancing classroom learning with a love for sports. Whether it was soccer, gymnastics, or basketball, young Hafþór was always moving, always competing. These school years weren’t just about academics—they were the training ground for a mindset built on discipline, competition, and growth.

Food Habits
He fuels like a Norse god in training. During his strongman peak, he consumed an eye-watering 8,000 to 10,000 calories a day, stacking his plate with eggs, bacon, steak, salmon, rice, and sweet potatoes like it was a full-time job. Think six eggs, piles of French toast, and a mountain of meat—all followed by a digestion walk. His signature shake? A high-powered blend of skyr, berries, oats, and peanut butter.
But when he stepped into the boxing ring, the Mountain slimmed down. Hafthor traded mass-gain madness for lean, focused fuel—think beef tenderloin, oatmeal, berries, and greens. Dairy took a backseat, inflammation went down, and performance went up. Whether it’s lifting boulders or throwing punches, Hafthor’s plate always mirrors his goal—big, bold, and built for impact.
Hobbies
Hafthor Bjornsson finds joy in the simple and strategic—like video games and chess, where he once held a Blitz rating of 800. Sports have always been in his DNA, from soccer and gymnastics to Brazilian jiu-jitsu and boxing. He also enjoys hunting natural stones with his family, a nod to Icelandic strength traditions. And at Thor’s Power Gym, he channels his passion into helping others grow stronger.

Net worth 2025
$2.5 million
As of December 2025, it’s estimated that Hafthor Bjornsson has a net worth of about $2.5 million. He’s a savvy businessman, a YouTube content machine, a record-breaking athlete, and now, a boxer. Over the years, he’s built a surprisingly diverse income portfolio—from Viking-strength powerlifting to brand deals, screen time, and even yogurt. Yep, skyr yogurt.
So, where exactly does The Mountain make his money? Let’s break it down.
1. Strongman Career — Where the Journey (and Paychecks) Began
Before all the cameras and endorsements, Hafthor made his name in the strongman circuit—dominating the global stage with titles like:
-
World’s Strongest Man – 2018
-
Europe’s Strongest Man – five-time winner
-
Arnold Strongman Classic – three-time champion
Each win came with sizable prize money. For example, winning World’s Strongest Man earned him around $75,000, and the Arnold Classic handed out $80,000+ to the champ. With multiple wins and appearances, his total prize earnings easily add up to $400,000–$500,000 over the years.
But the real value wasn’t just the checks—it was the global attention that turned him into a household name.
2. Acting – The Mountain That Changed Everything
Let’s be honest. The world met Hafthor as Ser Gregor “The Mountain” Clegane on Game of Thrones. He appeared in 17 episodes between Seasons 4 and 8, playing a character so terrifyingly silent and strong, fans couldn’t look away.
So how much did he earn? While he wasn’t among the top-billed actors, recurring characters on HBO hits can earn anywhere from $20,000 to $30,000 per episode. Multiply that over five seasons and you’re looking at around $350,000–$500,000, possibly more with residuals and royalties.
And the screen work didn’t stop there. He’s had roles in Kickboxer: Retaliation, a brief part in The Northman, and even did some voice work. Nothing blockbuster-sized, but enough to pad the income—and the IMDb page.
3. Boxing – The Big Pivot (and Bigger Payouts)
After retiring from strongman competitions, Hafthor took his power into the ring. His biggest match? The long-awaited bout against rival strongman Eddie Hall in 2022—billed as “The Heaviest Boxing Match in History.”
-
Estimated payout: $500,000–$1 million
-
Pay-per-view, sponsors, bonuses: Easily added six figures more
Since then, he’s taken part in other exhibition fights, with conservative estimates putting his boxing income between $600,000–$1.2 million depending on the year. For someone who was never meant to be a boxer, that’s a solid right hook to the bank account.
4. YouTube & Social Media – The Content Goldmine
This is where things get interesting. Hafthor’s YouTube channel isn’t just some side project. With nearly a million subscribers and videos that rack up millions of views, it’s a full-on business.
-
Estimated YouTube earnings:
Around $100,000–$120,000 per month, which adds up to $1.2–$1.4 million per year just in ad revenue.
And that doesn’t even include Instagram, where he has over 3.7 million followers. Sponsored posts, affiliate links, and brand collaborations likely bring in another $300,000–$600,000 annually.
He’s not just posting flexes and food—he’s building a digital empire, one rep at a time.
