Karl Chappe-Gatien

Karl Chappe-Gatien is a French day trader and professional poker player who resides in France. His recorded live tournament earnings exceed $4.16 million, placing him 538th on the all-time money list and 15th among French players. His best live cash is $2,600,000, his best all-time money list position was 463rd, and his current Global Poker Index ranking is 14,286th. Known for an aggressive yet calculated approach, Chappe-Gatien has made his name in the highest-stakes tournaments on the Triton Poker circuit.

Chappe-Gatien's career-best cash came in September 2022 during the Triton Mediterranean Poker Party. He finished third in the $200,000 buy-in Coin Rivet Invitational, taking home $2,600,000. Days later, he entered the first short deck no-limit hold'em tournament of his life, a $40,000 buy-in event at the same series, and won it for $565,000. The victory came against a strong field that included Jason Koon, Webster Lim, and Kiat Lee. In the final hand, Chappe-Gatien's pocket jacks held against Lee's top two pair when a ten on the river gave Chappe-Gatien a straight to clinch the title. Earlier in the event, he made a bold hero call to eliminate Jason Koon, a hand that became part of his reputation.

Chappe-Gatien returned to short deck action at the Triton Poker Super High Roller Series London, held at the JW Marriott Grosvenor House on August 8-9, 2023. He finished third in Event #15, a $30,000 + $1,800 No Limit Short Deck Hold'em Ante Only tournament. The event attracted 24 entries and 13 re-entries for a total prize pool of $1,110,000. Wai Yong of Malaysia won the event, Christopher Brewer placed second, and Chappe-Gatien took the final podium spot. The result reinforced his ability to perform in specialised variants against some of the world's top short deck specialists.

Outside poker, Chappe-Gatien works as a day trader. This background gives him a separate income stream and a natural affinity for probability and risk. When the FTX exchange collapsed in late 2022, he reportedly lost 35% of his net worth. Despite that blow, he has continued playing at the highest levels and remains active as both a trader and an investor.

In April 2023, Chappe-Gatien made headlines for an extraordinary act of generosity. After fellow French player Moundir Zoughari won the Marrakech Poker Open High Roller for roughly €55,000 and broke down emotional, Chappe-Gatien contacted him and offered a $100,000 freeroll to the next Triton Poker Series in Cyprus. The offer used a sliding scale: if Zoughari won up to $100,000, he would keep all of it; between $200,000 and $500,000 he would return $100,000; between $600,000 and $1,000,000 he would return $200,000; and above $1,000,000 he would return $300,000. The gesture highlighted Chappe-Gatien's generosity and his commitment to helping other French players break into high-stakes events.

Chappe-Gatien is often described as fearless and willing to take calculated risks. His decision to jump into a short deck event with zero prior experience and win it is a perfect example of that mentality. He is also recognised for his ability to read opponents and commit to bold decisions, such as the hero call that sent Jason Koon to the rail in his short deck triumph. His day-trading discipline likely supports his bankroll management and helps him stay calm in pressure-packed situations. Around the tournament circuit, he has built a reputation as a dangerous opponent who is willing to put chips at risk when his reads tell him it is correct.

Chappe-Gatien has crossed the $4,000,000 milestone in live tournament earnings. His current all-time money list position is 538th, with a best rank of 463rd. Among French players he sits 15th on the all-time list. His Global Poker Index ranking is 14,286th. These numbers, combined with his Triton trophies and deep high-roller cashes, place him among the most successful French players of his era, particularly in short deck and super high roller formats.
