David Geffen | $9.7 Billion

Although he began his career in the entertainment industry working at an agency’s mailroom, David Geffen has since become a successful businessman. Along the way, he’s had the chance to be the manager for artists like Laura Nyro and Crosby, Stills, and Nash. With that said, Geffen has also become known for spending his investment money on establishing Asylum Records, Geffen Records, and, alongside Steven Spielberg and Jeffrey Katzenberg, the DreamWorks studio.

Besides his many philanthropic efforts, Geffen has also spent a portion of his fortune on his prized collections. With a net worth of $9.7 billion, it comes as no surprise that he has his own yacht and art gallery, comprised of works by Jackson Pollock, Mark Rothko, and Jasper Johns. One piece he put up for sale in 2006, Pollock’s No. 5, 1948, was purchased for the incredible price of $140 million, making it the most expensive painting ever sold.
