50. Shawn Carter (Jay-Z)
bpoy jay-z

Co-owner, Brooklyn Nets

The man known as Jay-z owns less than 1% of the Brooklyn Nets (Russian billionaire Mikhail Prokhorov owns 80% of the basketball team), but Carter is the face of the team, and by extension, of his home borough. The rapper put in a mere $1 million into the initial partnership, but by all accounts was deeply involved in every aspect of the Nets' Brooklyn launch, including elements of its home stadium, the Barclays Center. The Nets are the latest addition to a business empire that includes New York's storied 40/40 Club and Roc-A-Fella Records. (He sold his clothing line, Rocawear, to Iconix in 2007 for $204 million.) Jay-Z the rapper may be winding down his career, but Shawn Carter the businessman is truly heating up after a fiery 2012. --DR
