Venetian Macao, China
Net worth: $35.8 billion
CEO and chairman of Las Vegas Sands company, Adelson opened the luxury Venetian Macao mega-resort in August 2007. Inspired by a visit to Venice in 1996 on his honeymoon, the hotel experience is today complete with canals and gondolas. Continuing to extend the firm's presence in Asia, Adelson saw the opportunity to fill the bay between the Coloane and Taipa islands in Macau, creating the Cotai strip in China, which now also hosts The St. Regis Macao and the Parisian Macao.
