Timely question, now that we're in the middle of the 2007 Series.
Going into the 2006 World Series of Poker, Jamie Gold and bodog.com entered into an agreement for Gold, a Hollywood talent agent, to arrange for celebrities to play in the WSOP's main $10,000-buy-in event; in exchange for a paid entry, the stars would publicize the online casino.
Gold made a side deal with Crispin Leyser, a TV producer and poker consultant, to help corral the celebrities. Leyser claimed that his payment was half of Gold's winnings in the tournament. After Gold won the grand prize of $12 million, Leyser, claiming that Gold reneged on the deal, sued Gold.
In late August 2006, several weeks after Gold won, a District Court judge froze the payment of the prize to Gold, to await settlement of the suit. In another hearing in December, it appeared -- from certain evidence, such as a phone-machine recording about the deal and a radio interview Gold did in which he mentioned it -- that Leyser's claim would prevail.
Finally, on Feb. 7, 2007, reports circulated that Gold and Leyser had settled. So yes, he had to share his winnings, though no details of the financial arrangement were revealed.
