Mark Shainberg's fortune prospered significantly, reaching an impressive $4.1 billion.
Mark Scheinberg, the Canadian businessman, co-founded PokerStars in 2001 with his father. Initially showing little interest in computers, Scheinberg was encouraged by his father to venture into the world of technology. This led to the conception of Rational Entertainment Enterprises, an online poker room that would revolutionise the industry.
PokerStars, under Rational, began operations on September 11, 2001, offering play money games initially. The company grew rapidly, but it wasn't until 2006 that the Unlawful Internet Gambling Enforcement Act (UIGEA) came into effect in the US, prohibiting online casinos, including poker operators, from processing "real money transactions". This marked a significant challenge for PokerStars.
Despite these obstacles, PokerStars continued to thrive. However, in 2011, the company and associated entities were indicted by U.S. authorities for alleged violations of laws prohibiting unlawful internet gambling, forcing the owners into settlements and restructuring. These legal battles made it difficult for them to continue business in key markets, particularly the U.S.
Although specific details about the precise end of Scheinberg's active partnership were not fully detailed in the search results, it is clear from a July 2025 report that Amaya Gaming, a Canadian poker operator, signed a new financial agreement with Isai and Mark Scheinberg as former owners of PokerStars, indicating Scheinberg no longer holds operational control over the brand.
The sale of PokerStars marked a significant shift in online poker ownership from founders to corporate entities, impacting how the brand and industry evolved. The sale also allowed PokerStars to further legalize operations in states like New Jersey from 2016 onward.
While no longer an owner/operator, Scheinberg remains a financial stakeholder or partner in agreements related to the business. His legacy as a pioneer in online poker remains significant, having amassed a billion-dollar fortune from the sale.
The legal cases against PokerStars influenced U.S. internet gambling law enforcement and how companies structure their compliance strategies. Despite the indictments, Isai Scheinberg and his son have not had the criminal charges against them dropped, preventing them from visiting the US.
Mark Scheinberg, at the age of 41, is currently single. His net worth is estimated to be $4.1 billion, making him the 10th richest person in Canada this year. Before founding PokerStars, Scheinberg dropped out of technological college to travel through Asia and South America. Isai Scheinberg, Mark's father, was born in the Lithuanian SSR and emigrated to Israel before moving the family to Canada in 1986.
PokerStars was blocked in the US in April 2011, but was later unblocked to allow for the payment of players. Mark Scheinberg received $3.7 billion + dividends for his share in the company following the acquisition. In August 2014, Amaya Gaming fully acquired Rational for $4.9 billion. Isai Scheinberg, Mark's father, won a high-stakes tournament at the UKIPT Isle of Man series.
In summary, Mark Scheinberg’s partnership ended because of pressures from legal indictments and changing market conditions, leading to the sale and transfer of PokerStars ownership, with lasting impacts on the online poker ecosystem and regulatory landscape.
