4. David Choe
Estimated Worth: £130 Million
In 2007 Facebook CEO Mark Zuckerberg commissioned the artist to paint murals for their next office. Although he thought the Facebook business model was “ridiculous and pointless,” Choe, who happens to be an habitual gambler, chose to receive company stock in lieu of a cash payment for the original Facebook murals. His shares were valued at approximately $200 million on the eve of Facebook’s 2012 IPO.
