Triton Poker has announced a landmark heads-up match set for Friday evening in South Korea, as Poker Hall of Famer Patrik Antonius takes on cash game specialist and businessman Ossi “Monarch” Ketola. The two will play for a staggering $20,000,000 on the Triton Super High Roller Series Jeju II stage.
The event is being billed as the largest televised heads-up match in poker history and will stream live via Triton Poker’s YouTube channel and the Triton Poker Plus app.
Ketola has become one of the most talked-about figures in high-stakes poker over the past year. He first drew major attention at this same festival in 2025, when he won a record-setting $10.99 million pot against Alex Foxen.
Since then, Ketola has faced off against several top names, including Kayhan Mokri and Dan “Jungleman” Cates, cementing his reputation as one of the sport’s most fearless nosebleed players. Just days before this latest match, he defeated Wiktor “Limitless” Malinowski for $6,000,000 in a high-stakes series featuring multiple seven-figure pots.
Antonius, meanwhile, remains one of the most respected cash game players in poker history. In 2023, he won what was then the largest streamed cash game pot in U.S. history, a $1,978,000 hand on “Cash of the Titans.”
Beyond Friday’s clash, the two will also team up as partners for Saturday’s $200,000 Triton Invitational in Jeju, marking the first time the event has been held in Asia, with 50 pairs already confirmed to compete.
