from that article: (very good read!)
The ownership rolls of offshore casinos read like a Who's Who of America's top investment firms. For example, public filings show that tens of millions of shares of SportingBet, a company listed on the London Stock Exchange that allows people to place bets on sporting events, are owned by Fidelity, Merrill Lynch and Goldman Sachs.
Fidelity Management holds shares worth about $363 million, or 14.1 percent of the outstanding shares. Those shares are largely held in mutual funds. Merrill Lynch Asset Management has $164 million in holdings, and Goldman Sachs Group Inc. has $137 million.
Similarly, Goldman Sachs and Morgan Stanley Securities hold big positions in BetOnSports, another publicly traded firm in London that facilitates sports betting, according to public filings. Morgan Stanley has one of the biggest stakes - worth around $25.6 million - but the company said that the position is held on behalf of one large investor, whose identity it withheld.
