  • Nicknamed the Queen of QVC, Lori Greiner has created more than 500 products and has over 120 patents to her name
  • From IT whizz Robert Herjavec to real estate expert Barbara Corcoran, which host of ABC’s reality TV show has the most in the bank?

The cast of reality show Shark Tank might have pumped millions into helping budding entrepreneurs launch their dream businesses, but how did they earn their own fortunes, and just how much are the each worth? Let’s take a closer look at the figures (all sourced from Celebrity Net Worth and correct at the time of publication).

Cuban has been a wealthy businessman for a long time – he started selling garbage bags at the age of 12, and after investments in multimedia platforms he became a billionaire in 1999, the same year his broadcast.com streaming service sold to Yahoo.

Perhaps best known for being the owner of the NBA’s Dallas Mavericks team, which he bought in 2000, this basketball boss also co-owns Landmark Theaters and Magnolia Pictures – making this shark the biggest name in the entertainment industry.

Selling his SoftKey International company (now The Learning Company) to Mattel for US$4.2 billion in 1999, after founding it in 1986, isn’t the only thing that has made O’Leary the second-wealthiest shark. The Canadian entrepreneur co-founded Storage Now in 2003, which provides temperature controlled storage to companies including Pfizer. Under his diverse roster of companies there’s also O’Shares ETFs, O’Leary Publishing and O’Leary Fine Wines.

Daymond John – US$350 million
