Ossi Ketola Wins $20M Biggest Livestreamed

On September 11, 2026, Triton Jeju hosted a $20 million winner-take-all heads-up match where Ossi Ketola defeated Patrik Antonius after over four hours, setting records for the largest livestreamed heads-up buy-in and single-session loss.

On the night of September 11, 2026, at Les A Casino on Jeju Island, South Korea, on the stage of the Triton Super High Roller Series Jeju II, two Finns sat down at the same table. On one side was Poker Hall of Famer Patrik Antonius; on the other was casino entrepreneur Ossi Ketola, known as "Monarch." Each bought in for $10 million, the prize pool was $20 million, winner takes all, with blinds at $50K/$100K. A little over four hours later, Ketola had all the chips.

Antonius lost $10 million in a single match. Multiple poker outlets framed it as: the highest-stakes heads-up match ever publicly livestreamed, and the largest single-session paper loss in livestreamed poker history.

This was not an unverifiable rumor game in a private room. Triton's official YouTube and Triton Poker Plus broadcast the entire match, with a replay running approximately 4 hours and 27 minutes. The numbers can be rewatched, and the hands can be checked one by one.

What Exactly Did This Match Break

Poker records are often overstated. This one needs to be broken down by category:

Category	Status	Source
Publicly livestreamed/televised heads-up buy-in and prize pool	$20 million, the largest in publicly broadcast poker to date	Triton official, PokerNews, SoMuchPoker, poker.pro
Largest single-session livestreamed loss	Antonius's $10 million	Same as above
Largest livestreamed single-hand pot	Still the $12.7 million pot between Ketola and Bjorn Li at the same venue in 2025	Poker.org, SoMuchPoker
"Largest heads-up match in human history"	If counting only verifiable public matches, this is the current benchmark; if including untelevised private mega-games (such as the rumored Andy Beal series), no empirical ranking is possible	Public records missing

In one sentence: what it broke was the scale of a heads-up match that can be timed and replayed on camera, not the history of unverifiable private games.

Who Are These Two

Patrik Antonius: The Orthodox High-Stakes Pro

Antonius was born on December 13, 1980, in Helsinki and grew up in Vantaa. He played tennis as a youth, turned to poker after a back injury, and also did some modeling. In 2005 he won the EPT Baden main event (€288,180), then became a regular at the highest online stakes during the Full Tilt golden era, facing off against Tom Dwan, Phil Ivey, and Viktor Blom—then known as Isildur1. In November 2009, he played what was at the time the largest online pot against Blom, approximately $1.357 million.

In 2023, he won a pot of roughly $1.978 million on PokerGO's No Gamble, No Future, which was then the largest pot in U.S. livestreamed poker history. In July 2024 he was inducted into the Poker Hall of Fame, one of the few Europeans to enter in recent years. In November of the same year, he won the $200K Triton Invitational in Monte Carlo, taking home his career-largest tournament score of $5.13 million—his entry into that invitational was directly connected to Ketola.

Live tournament earnings figures vary depending on when databases are updated. PokerNews, citing The Hendon Mob, puts it at approximately $34.68 million. He currently resides in Monte Carlo.

Before the match, he said on Instagram that this was, to his knowledge, the largest public/televised heads-up match ever: "I'll really be nervous. It's not like a normal day." Finnish outlet nettipokeri recorded the original quote, along with his addition that the terms took a long time to negotiate, that the first match might not be the last, and that a rematch was possible.

Ossi "Monarch" Ketola: Using His Own Money to Push Heads-Up to Depths Pros Rarely Accept

Ketola was born in 1997 in Vammala, Finland (now part of Sastamala), making him about 28–29 years old. Both Finnish Wikipedia and PokerListings note that he started doing business as a teenager, founding the CS:GO skin gambling site CSGOEmpire in 2016 with an approximately €11,000 loan, and later launching the crypto casino Duel.com.

He is not a traditional touring pro. He only made a large-scale appearance at Triton Monte Carlo in late 2024, with his best result being runner-up in a $150K event for about $2.97 million. What truly brought him into poker's mainstream consciousness was that in 2025 he almost single-handedly pushed livestreamed cash games into eight figures:

An approximately $10.99 million pot against Alex Foxen (then a livestream record)
Days later, an approximately $12.7 million pot against Bjorn Li, still the benchmark for the largest livestreamed single-hand pot
In a series of heads-up matches against Dan "Jungleman" Cates in Cyprus the same year, multiple outlets reported he net-lost approximately $15 million / €15 million (buy-ins denominated in euros, pots often displayed in dollars, so conversion figures are not entirely consistent)

Just days before the Jeju stop began, he won approximately $6 million from Wiktor "Limitless" Malinowski. Duel is the official sponsor of this Triton Jeju stop, and "Duel Heads-Up" is itself part of the sponsorship package.

They Are Not Strangers

Ketola had previously invited Antonius to play the Triton Invitational. Antonius won that event in Monte Carlo in 2024, taking the $5.13 million. Some reports also mention that Antonius had some collaboration with or publicly endorsed the launch of Duel. This $20 million match was both a high-stakes battle and an intersection of business and personal relationships.

The next day, the two appeared as partners in the $200K Triton Invitational—the first time that event was held at an Asian stop. Ketola was the inviter, Antonius the professional partner. The $10 million did not, in the moment, break their personal relationship.

How the Match Played Out

For most of the match, it was not as crazy as the numbers sound. Over four-plus hours, the lead changed hands multiple times. SoMuchPoker's chip-trajectory reconstruction based on the livestream timing was roughly:

Antonius dropped to a low of about $6.1 million
At about the 2-hour-40-minute mark, he briefly led at $10.1 million
At 3 hours 39 minutes, the two were separated by only about $500K (Ketola $10.5M / Antonius $9.5M)
What truly decided it was concentrated in the final ~45 minutes, when about $9.5 million changed sides in two hands

The headline of Finnish outlet nettipokeri's recap was blunt: Ketola played more aggressively, Antonius avoided risk. Throughout the match, there were very few collisions where both players held monster hands. A freezeout heads-up match starting at 100 big blinds stretches time out considerably.

The Massive Bluff Near the Start

Multiple outlets noted Ketola's willingness to size bets to a level that made his opponent "uncomfortable." Details vary slightly across reports, but two types of situations reliably occurred:

Five-high overbet. SoMuchPoker, cross-referencing the livestream, wrote: less than an hour in, Ketola with 5♠2♠ on a T♣ A♣ 6♠ / 4♠ turn fired $1.8 million into a $1.2 million pot (about a 150% overbet), and Antonius folded an already-made pair of tens.
Six-high ~$3 million pressure. poker.pro, Poker.org, and nettipokeri all wrote about another hand: Ketola with an extremely weak hand (described in reports as six-high or similar) fired about $3 million on the river, forcing Antonius to fold top pair.

The two hands need not contradict each other. They point to the same thing: Ketola was willing to use million-dollar sizings to buy folds, and Antonius repeatedly chose not to call.

Straight Flush vs. Straight: The Night's Most Beautiful Hero Fold

This is the most retold hand. Livestream time approximately 4:15. At that point Ketola had about $13.1 million, Antonius about $6.5 million.

Ketola: Q♥9♥
Antonius: K♦9♠
Flop: Q♠ 8♥ J♥ (Ketola top pair + straight flush draw; Antonius open-ended straight draw)
Turn: T♥. Ketola made a heart straight flush; Antonius made a king-high straight, already drawing dead.
Antonius bet $625K on the turn, Ketola raised to $1.6 million, Antonius called.
After the river 3♣, Ketola shoved. Antonius had about $4.1 million behind. A call would end the match.

After a long tank, Antonius folded the straight. Triton's official account posted at the time: "STRAIGHT FLUSH FOR $15.925 MILLION." That number corresponds to Ketola's chip count after the fold / the shove display size, not the pot Antonius actually lost—after he folded, the pot itself was about $4.95 million, and the score became roughly $15.95M to $4.1M.

Most outlets called it the night's most beautiful hero fold: three hearts on board, no heart in hand, and the straight wasn't even the nuts (A-K would be Broadway), while his opponent had been applying maximum pressure all night. Difficult, but correct in direction.

The Deciding Hand: AK vs. KJ, a Jack on the Turn

The next hand. Antonius held A♦K♦, Ketola K♣J♣. Preflop, Ketola four-bet shoved, and Antonius snap-called. At that point equity was about 71% to 28%, with a pot of about $8.15 million.

Board: 5♣ 9♠ Q♠ / J♠ / 7♣. The flop still had ace-high in the lead; the turn jack gave Ketola a pair of jacks, and the river changed nothing. The match was over.

At the table, Antonius's immediate reaction was brief. Poker.org recorded him saying: "Not my day."

Afterward, What He Said Himself

On September 13, nettipokeri, citing Antonius's Instagram Story, wrote that he was unhappy with his own performance. The gist of the original quote was—

I was waiting for him to make a mistake, trying to play position. I played too conservatively.

He praised Ketola for playing well and noted that in poker you try different strategies, sometimes they work, sometimes they don't. This time, he was dissatisfied with both the result and his own play.

In the same set of Stories, he also said he woke up the next morning with a headache and stomach pain, still grinded through Day 1 of the Invitational, running his 300K starting stack up to 229K without rebuying. nettipokeri, citing PokerNews's live coverage, reported that he was eliminated on the second day by Punnat Punsri: both made a pair of kings, and Punsri's AKo kicker dominated Antonius's KQo. PokerNews's rolling live page updates quickly, and this article was unable to independently open that specific hand report; this detail is based on the Finnish outlet's retelling.

The personal relationship did not sour on the spot. The two still appeared as partners in the Invitational the same day.

The Undercurrent of Public Opinion Off-Camera

Triton's official account pushed the whole thing as a "historic night": the start, million-dollar bets, cooled pots, the straight flush, the deciding hand. This is sponsored content, and it is also the event product.

Controversy arose simultaneously. YouTuber BobbyJamesPoker pointed out the structural issue: two Finns, the Duel owner against Antonius, Duel sponsoring Triton, the Duel heads-up match itself being part of the sponsorship package, and then sitting down to play $20 million winner-take-all. This is not evidence, but the poker community's instinctive suspicion of "a sponsor playing in its own brand's biggest heads-up match." Poker.org, meanwhile, stated plainly: they believe the money is real, but insisted on including Ketola's sponsor status, as well as his previously documented racist remarks on social media and livestreams, in their reporting. Ketola's personal X account and those associated with Duel and CSGOEmpire had previously been banned. These are public records, not factors in the match's outcome, yet they form the undercurrent of public opinion that this "historic night" cannot shed.

Technical discussion was more specific. Some praised Antonius's straight fold; some said he overfolded throughout the match; others emphasized bankroll and mindset—how important bankroll management is if you want to play your A-game, and this match was a lesson. Poker.org also recorded a table-side exchange: Antonius asked him if he was nervous, and Ketola admitted "a little, at a low intensity," but said it was different from playing a million.

What It Proved, and What It Didn't

A four-hour freezeout heads-up match starting at 100 big blinds has enormous variance. One turn card can rewrite the headline. Antonius played tighter in the face of the money, Ketola dragged the match into the aggressive zone where he was more comfortable, and it ended on a bad turn card in an AK vs. KJ hand. This cannot prove who the better player is. Over a longer series, the skill gap would typically become clearer.

What it truly leaves behind is a number that can be rewatched, timed, and analyzed hand by hand: two Finns, on camera, putting $20 million into the same pot, and then one of them walking away with it.

The full replay is on Triton Poker's YouTube channel. SoMuchPoker's hand-by-hand recap is currently one of the most complete public written records.
