Matthew Stout is an American professional poker player, five-time World Series of Poker Circuit (WSOPC) ring winner, and the visionary founder of the Charity Series of Poker (CSOP). Originally from Bayonne, New Jersey, and now a prominent figure in the Las Vegas poker scene, Stout has built a reputation as one of the game’s most consistent and community-focused professionals. With a career spanning over two decades, he has transitioned from a high-volume online grinder to a respected live tournament veteran. In 2026, Stout continues to balance a heavy tournament schedule with his philanthropic work, leading the CSOP through its most successful season to date with over $8 million raised for global charities.
Career Earnings & Tournament Success
As of March 2026, Matthew Stout’s total live tournament earnings exceed $4,601,300 (according to The Hendon Mob). A specialist in No-Limit Hold’em and Pot-Limit Omaha, Stout has reached the final table of nearly every major tour, including the World Poker Tour (WPT) and the WSOP . His resume is highlighted by five WSOP Circuit rings, including a dominant 2020 performance where he secured two rings in a single month. His deep run in the 2024 WSOP Main Event (190th for $60,000) and consistent cashes in the 2025 series prove his enduring edge in the modern era. His combined live and online success, where he is known by the legendary handle “All In At 420”, contributes to an estimated poker net worth of over $5.5 million.

Philanthropy: The Charity Series of Poker (CSOP)
While his skills at the table are undeniable, Stout’s greatest legacy may be his impact off the felt. In 2014, he founded the Charity Series of Poker (CSOP), a non-profit organization that hosts world-class poker events to benefit causes such as St. Jude Children’s Research Hospital, Habitat for Humanity, and Three Square Food Bank. In 2026, the CSOP remains a cornerstone of the poker social calendar, frequently featuring stars like Daniel Negreanu , Phil Hellmuth , and celebrities like punk legend Fat Mike. Under Stout’s leadership, the series has evolved into a full-scale production company, providing tables, dealers, and professional tournament staff to help various charities maximize their fundraising efforts.
Play Style & Tactical Approach
Stout is widely regarded as a “highly adaptable and resilient” tournament specialist. Having cut his teeth in the aggressive online era of the mid-2000s, he maintains a sharp mathematical foundation while incorporating a “feel-based” live approach. His strategy often centers on exploitative adjustments against less experienced fields, but he is equally capable of battling the world’s best in GTO-heavy environments. Stout is particularly vocal about mental health and balance in poker, often sharing insights into how fatherhood and his charity work have provided him with the perspective necessary to handle the high-variance nature of the professional circuit.
