PokerStars

History & Corporate Evolution

PokerStars was founded in 2001 by Isai Scheinberg and his son Mark Scheinberg under the company Rational Group. Initially operating from Costa Rica, the platform quickly gained traction by offering reliable software, frequent tournaments, and a wide variety of poker variants. In 2006, following the U.S. Unlawful Internet Gambling Enforcement Act (UIGEA), PokerStars continued to serve the U.S. market until the “Black Friday” crackdown in April 2011, when the U.S. Department of Justice seized its .com domain. The company later reached a settlement, returned funds to American players, and re‑entered the U.S. regulated market through partnerships (e.g., in New Jersey). In 2014, Rational Group was acquired by Canada‑based Amaya Gaming for US$4.9 billion, which subsequently renamed itself The Stars Group. The Scheinbergs exited the business at that time. In 2020, Flutter Entertainment (owner of Paddy Power, Betfair, FanDuel, and others) merged with The Stars Group in a £6 billion deal, creating the world’s largest publicly listed online gambling operator. PokerStars now operates as a key brand within Flutter’s International division.
