The Top 10 World's Richest Entrepreneurs
5. Sheldon Adelson - $38 billion
Sheldon Adelson may have sunk millions into the failed presidential campaigns of Republican hopefuls in 2012, but with a net worth of $38 billion, he's still the eighth richest person in the world. Today, he is the chairman and CEO of the Las Vegas Sands Corporation, but he got his start in the computer trade show circuit. He and his business partners held their first COMDEX--a massive computer expo in Las Vegas--in 1979.
