John Cynn

John Cynn was born on December 24, 1984, in Northbrook, Illinois. He attended Glenbrook South High School, where he began playing poker for fun with friends. After high school, he enrolled at Indiana University Bloomington, graduating with a degree in finance and supply chain management. Following college, Cynn moved to California and worked as an IT consultant, a career he pursued before transitioning to professional poker.

Cynn's first live tournament cash came in 2010, and he recorded his first World Series of Poker (WSOP) cash in 2012. He accumulated a number of smaller results over the next few years, gradually building his bankroll and experience. By 2016, he had established himself as a regular on the tournament circuit, with multiple cashes in WSOP and World Poker Tour (WPT) events.

Cynn's first major breakout came in the 2016 WSOP Main Event. He navigated a massive field and reached the final table's unofficial nine, ultimately finishing in 11th place when he was eliminated on the bubble of the televised November Nine. That finish earned him $650,000 and served as a springboard for his poker career. The deep run gave him the confidence and financial stability to pursue poker full-time.

The defining moment of Cynn's career arrived in the 2018 WSOP Main Event. The tournament attracted 7,874 entries, the second-largest field in WSOP history at that time. Cynn survived countless eliminations to reach the final table, which included former champion Joe Cada. The final table stretched over ten hours, and Cynn's heads-up battle against Tony Miles lasted 199 hands. On the 442nd hand of the final table—hand 199 of heads-up—Cynn held K♣ J♣ against Miles' Q♣ 8♥ on a board of K♥ K♦ 5♥ 8♦ 4♠. Cynn's two pair secured the pot and the championship, earning him the $8,800,000 first prize and his first WSOP bracelet. The victory propelled him to worldwide recognition and placed him firmly among poker's elite.

Beyond his Main Event win, Cynn has numerous other notable scores. In the 2017 L.A. Poker Classic, a WPT event, he finished 10th for $80,280. He also cashed in the 2017 WPT Bay 101 Shooting Star Main Event, placing 74th for $13,660. In the 2019 partypoker MILLIONS South America High Roller, he came 4th for $110,000. A year later, in the 2020 partypoker MILLIONS Sochi Short Deck Hold'em, he finished runner-up for $252,000. At the WSOP, he has recorded additional cashes, including 21st in a 2017 $1,500 Six-Handed event ($15,919) and 38th in another $1,500 No-Limit Hold'em ($8,183). He also made a deep run in the 2018 Millionaire Maker ($2,468). In 2022, he cashed in the WSOP Main Event again, placing 550th for $25,500. Most recently, in 2026, Cynn returned to the WSOP and cashed in the Main Event (617th, $27,500) and also placed third in Event #17: $10,000 No-Limit 2-7 Lowball Draw Championship for $198,302, demonstrating his adaptability to mixed games.

Cynn is known for a patient, disciplined playing style. He tends to play conservatively in the early stages of tournaments, avoiding unnecessary risks and carefully selecting his spots. As the tournament progresses and his stack accumulates, he becomes more aggressive, leveraging his chips and reading opponents' tendencies. His ability to remain calm under pressure—showcased during the long heads-up battle in 2018—has been noted by commentators and peers. Cynn emphasizes the importance of emotional control and continuous learning, values he credits for his success.

After his 2018 win, Cynn's tournament schedule became less active, but he continued to compete in select high-profile events. In 2022, he played in the WSOP Main Event, and in 2026, he recorded two cashes, including a final table in a $10,000 Lowball event. His total live tournament earnings exceed $10.2 million, placing him among the top 70 American players on the all-time money list. Cynn's victory remains one of the most memorable in WSOP history, not only for the sizable prize but also for the dramatic heads-up duel. He is often cited as an example of a player who achieved poker's biggest prize after starting the game seriously later in life, inspiring many amateur players. He is also a WSOP bracelet winner and a Global Poker Awards recipient.
