Shark Tank has become a big hit for ABC since debuting in 2009, garnering consistently high ratings and three Primetime Emmys over the course of its run. So what makes it so popular? The show undoubtedly owes part of its success to its stellar cast of business moguls, who dole out sage (and sometimes harsh) advice to the aspiring entrepreneurs that enter the tank.
The six cast members have earned their expertise — and massive fortunes — after years of launching successful business ventures in their respective fields. But though they each rake in big bucks from their various investments, some of their careers have been more profitable than others. So which Shark is the richest of them all? Keep reading to find out who boasts the highest net worth.
6. Lori Greiner
Net Worth: $70 million
Lori Greiner, often dubbed the “queen of QVC,” has served as a celebrity personality and host on the shopping network for nearly 20 years. She is also the president and founder of the Chicago-based product development and marketing company, For Your Ease Only.
She’s launched more than 400 products and holds over 100 U.S. and international patents. One of her most successful Shark Tank investments? Scrub Daddy, the uniquely designed sponge that has garnered over $70 million in sales from a variety of stores, including Bed Bath & Beyond, Walmart, Target, and Staples, and is one of the show’s biggest success stories to date.
5. Barbara Corcoran
Net Worth: $80 million
Barbara Corcoran earned her millions in real estate, founding The Corcoran Group in 1973. She boosted the brand’s profile by publishing The Corcoran Report, an analysis of real estate data trends in New York City, in the mid-1970s, and eventually sold the successful business to NRT Incorporated for $66 million in 2001.
In addition to her Shark Tank duties, Corocoran is also a real estate contributor to various media outlets and a business consultant via her consulting and television production company, Barbara Corcoran Inc. — all of which contributes to her $80 million net worth.
4. Robert Herjavec
Net Worth: $200 million
The technology mogul sold his first two internet companies, BRAK Systems and RAMP Networks, for $335 million to AT&T and Nokia, respectively. In 2003, he founded his own company, the Harjavec Group, which is now one of the world’s leading global information and cyber security firms.
He earns additional money through his ventures on Shark Tank, which he has appeared on for all eight seasons. All of this puts his total net worth at around $200 million, although there have been reports that this figure may have taken a hit as a result of his 2016 divorce to ex-wife Diana Plese.
3. Daymond John
Net Worth: $250 million
Unlike some of his fellow Sharks, Daymond John still serves as the CEO and founder of the original company that made him wealthy, FUBU. The fashion company became hugely popular in the mid-1990s after John’s friend, LL Cool J, wore the clothing. The brand is now worth about $6 billion.
That, combined with his stakes in various Shark Tank products and his side gig as a popular consultant and public speaker, puts his net worth at approximately $250 million.
2. Kevin O’Leary
Net Worth: $400 million+
Kevin O’Leary is known for his abrasive, no-holds-barred approach on Shark Tank, earning him the nickname “Mr. Wonderful.” But many would argue that he’s earned his right to be blunt.
The businessman started his first company, SoftKey Software Products, in his basement, shortly after graduating from college. Within a few years, SoftKey had taken off. O’Leary went on to buy out almost all of its competitors, including The Learning Company, before selling the company to Mattel for $3.7 billion in 1999.
He now serves as the founder and chairman of mutual fund company, O’Leary Funds Inc., which — along with his Shark Tank investments — boosts his net worth to over $400 million.
1. Mark Cuban
Net Worth: $3.4 billion
Forbes estimates that Mark Cuban has a net worth of a whopping $3.4 billion. The remarkably successful businessman has earned his wealth through a variety of savvy projects, including co-founding video portal Broadcast.com and later selling it to Yahoo for $5.7 billion in 1999.
Cuban has also invested in Landmark Theaters, Magnolia Pictures, and AXS TV and owns the NBA team, the Dallas Mavericks. He’s served as a Shark for six of the show’s eight seasons.
