Since debuting in 2009, Shark Tank has had viewers glued to their television screens watching millionaire and billionaire investors like Mark Cuban, Kevin O’Leary, Robert Herjavec, Lori Grenier, Barbara Corcoran, and Daymond John analyze business proposals from hopeful entrepreneurs.

There’s no doubt that all of the main “sharks” are incredibly wealthy and successful (collectively, they have invested over $200 million into products and businesses from the award-winning show), but who is the richest? That answer may surprise you. Read on for the estimated net worth of the central cast of Shark Tank.

Barbara Corcoran: $100 Million Net Worth

After college, Barbara founded a real estate company with her boyfriend — but years later, she said goodbye to the boyfriend and as well as the company, which was sold for $66 million. From there, she launched real estate company The Corcoran Group which she still works on today. Corcoran credits her success with investing in a nice wool coat, shelling out $320 from her first commission check to pay for it.

Lori Grenier: $150 Million Net Worth

Known for promoting successful products on QVC and The Home Shopping Network, Lori started out with a $300,000 loan to help her create a prototype of an earring organizer which was later purchased by J.C Penney. Since joining Shark Tank in the first season, she invested in one of the most successful products to ever be on the show — Scrub Daddy, which has over $100 million in sales.

The Croatian-born investor is the founder of the internet security software, BRAK System, which was sold to AT&T for more than $30 million. His estimated net worth now is 10 times that amount, of course.

Daymond John: $350 Million Net Worth

The fashion mogul is best known for being the CEO of FUBU, which has generated over $6 billion in global sales. On Shark Tank, he’s invested over $8 million of his own money into various companies. His net worth is one of the highest for the sharks, at an estimated $350 million.

Kevin O'Leary: $400 Million Net Worth

There’s a reason why Mr. Wonderful enjoys the finer things in life. During the earlier years of his career, the businessman got a $10,000 loan from his mother, which helped him co-found SoftKey Software Products which was later acquired by Mattel for more than $3 billion. Still, O’Leary knows how difficult it is to amass $1 million, let alone the $400 million he’s estimated to be worth now. He’s admitted, “It’s almost impossible.”

Mark Cuban: $6.86 Billion Net Worth

Not only is the Dallas Mavericks owner the richest shark on Shark Tank, but he’s also one of the wealthiest men in America. Growing up, Mark believed in hustling to earn every penny — and would sell stamps door-to-door as a kid. He sold Yahoo! for $4.8 billion in 1999, according to Bloomberg, which is what catapulted him to extreme riches. Today, he also has stakes in Landmark Theaters, Magnolia Pictures, and AXS TV. His net worth has only continued to grow in recent years.
