Karl Chappe-Gatien

Karl Chappe-Gatien is a French professional poker player and day trader, currently residing in France. his total live tournament earnings exceed $4.16 million, placing him 538th on the all-time money list and 15th among French players. He is known for his aggressive yet calculated style and has made a name for himself in high-stakes events.

Chappe-Gatien's career-best cash came in September 2022 at the Triton Mediterranean Poker Party. In the $200,000 buy-in Coin Rivet Invitational, he finished third, earning $2,600,000. Just days later, he entered his first-ever short deck no-limit hold’em tournament—a $40,000 buy-in event at the same series—and won, taking home $565,000. This victory was particularly notable as he overcame a tough field including Jason Koon, Webster Lim, and Kiat Lee. In the final hand, his pocket jacks held against Lee's top two pair when a ten on the river gave Chappe-Gatien a straight to secure the title.

Outside of poker, Chappe-Gatien works as a day trader. In the wake of the FTX collapse in late 2022, he reportedly lost 35% of his net worth. Despite this setback, he remains an active high-stakes player and 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 ~€55,000 and broke down in tears, Chappe-Gatien reached out and offered him a $100,000 freeroll to the next Triton Poker Series in Cyprus. The agreement had a sliding scale: if Zoughari won up to $100,000 he kept it all; between $200K–$500K he would return $100K; $600K–$1M return $200K; over $1M return $300K. This story highlighted Chappe-Gatien's philanthropic side and his connection to the poker community.

Chappe-Gatien is described as a fearless competitor who is willing to take calculated risks, as evidenced by his plunge into short deck without prior experience. He is also known for his ability to read opponents and make bold moves, such as the hero call that eliminated Jason Koon in the short deck event. His background in day trading likely contributes to his disciplined bankroll management and psychological resilience.
