Journal reported that Diller, David Geffen and his stepson, Alex Von Furstenberg were being investigated by the Securities and Exchange Commission and the United States Department of Justice for insider trading of options on Activision Blizzard just three days before Microsoft's announced acquisition. Diller denied the allegations and claimed it was "It was simply a lucky bet." Personal life In 2001, Diller married fashion designer Diane von Fürstenberg, mother of Prince Alexander von Fürstenberg and Princess Tatiana von Fürstenberg. He is a member of the Democratic Party and supporter of related political causes. As of June 2020, Diller's estimated net worth was $4.2 billion. He owns a superyacht. Diller's sexual orientation has been discussed in the media. In James B. Stewart's 2005 book DisneyWar, erstwhile Paramount colleague Michael Eisner characterized Diller as "a homosexual." In 2001, New York Magazine'''s Maer Roshan wrote:The recent wedding of Barry Diller and Diane Von Fürstenberg epitomizes the media’s convoluted approach to covering gay celebrities. I would not presume to speculate on their relationship, which is said to be a warm and genuine one. But it’s also true that Diller did not live as a monk before his marriage at the age of 59 – in fact, while Diller is often referred to as bisexual, he has lived most of his adult life as a more or less openly gay man. He has had both short-term boyfriends and long-term relationships (including one with a former editor-in-chief of The Advocate); he appears frequently at gay parties and gay benefits. His sexual orientation has even been referred to in print with regularity. Still, because Diller had never actually sent out a press release acknowledging he was gay, journalists faced with the news of his wedding were in a quandary: All across Manhattan, reporters offered various explanations – financial and otherwise – for his apparent midlife transformation. But none, of course, made it into print. Philanthropy In 2011, the Diller-von Fürstenberg Family Foundation announced a donation of $20 million to support the completion of the High Line park in Manhattan. In 2012, Diller donated $30 million to the Hollywood Fund, which provides health and social care to retired individuals from the show-business world. In 2015, Diller and his wife committed to donate $260 million toward Little Island, a public park and performance space on a reconstructed pier in the Hudson River in New York City. It is stated
