Mark Cuban – $4.5 Billion
He’s not just great in business, but Mark Cuban is excellent when it comes to TV. After all, he has been one of Shark Tank’s investors since 2011. Right now, Mark’s fortune is estimated at $4.2 billion. He owns the Dallas Mavericks from the NBA, but he’s also a chairman at AXS TV and part-owner of 2929 Entertainment, LLC. Despite his busy schedule as a businessman, Mark cleared his schedule long enough to appear in both the Brooklyn Nine-Nine and the Grace and Frankie series within 2020. He has been married to Tiffany Steward since 2002, with whom he’s had two daughters and a son.
