The face of Nike's Air Jordan sneakers, a brand relationship from which he earned an estimated $90 million in 2013 alone, Jordan also invests money in other sports ventures. In 2010, Jordan purchased an 80 percent stake in the Charlotte Bobcats, for close to $200 million. Did we forget to mention Jordan also owns seven restaurants and a car dealership? He does.
