Mark Cuban didn’t just bring personality to Shark Tank – he also brought serious business chops. Since joining the show as a full-time member in Season 3, the billionaire investor has poured millions into startups, with the sole aim of turning smart ideas into massive paydays. And now, several years later, the numbers are in.
Let’s just say Cuban’s time in the tank paid off in a big way, and his track record further proves why he’s one of the sharpest sharks on the panel. Here’s a closer look at just how much money Cuban has made on Shark Tank – and why fans are calling him a legend.
Why Mark Cuban’s time on Shark Tank was the best business move of all?
Mark Cuban may be saying goodbye to Shark Tank after Season 16, but he’s leaving with one of the most impressive financial wins in the show’s history. That’s right – after 15 seasons and hundreds of pitches, the billionaire investor has revealed just how much he made from his time in the tank – and the numbers are staggering.

Cuban joined the show in Season 3 and went on to invest around $33 million in businesses featured on the show. While not every deal turned profitable, many of them did deliver big results. In fact, he told CNBC that he has received $35 million in cash returns, and his remaining equity in those businesses is now worth at least $250 million.
That’s a massive return on investment by any standard – and proof that Cuban’s instincts are as sharp as ever. But not every venture of his was a success. One of the biggest failures was Breathometer, a smartphone breathalyzer pitched in 2013. All five sharks joined in on a $1 million deal, but the product later ran into trouble.
And because of this, and the founder not being serious enough about the product, Cuban said that it was one of his worst investments. Still, his list of wins far outweighs the losses. Investments in brands like Tower Paddle Boards, Simple Sugars, and Prep Expert have brought him long-term gains.
So, as he steps away from the tank, Cuban leaves behind a legacy of smart decisions – and one of the most successful investment runs in Shark Tank history.
Mark Cuban bids farewell to Shark Tank with a heartfelt toast

Mark Cuban has officially ended his Shark Tank journey, and his final episode aired on May 16 and is now available to stream on Hulu. The billionaire entrepreneur first joined the show in Season 2 as a guest judge, but fans loved him so much that he was ultimately brought in as a full-time cast member in Season 3. He then quickly stood out for his bold decisions and honest feedback.
And with the same honesty, in his final episode, he gave a heartfelt toast to the panel and, of course, the fans. He addressed his fellow Sharks and said:
I’ve learned so much from all of you. And to Shark Tank, the people who supported us, the people who love us – I love you guys like family.
After this, each Shark shared some warm words for Cuban, but as always, Kevin O’Leary stood out from the lot. The duo has clashed multiple times on the show, but here, O’Leary raised a toast and said:
I’m so proud of what we’ve all built together. We have become ambassadors of the American Dream around the world. So much of it is because of you.
While fans are definitely heartbroken that Cuban left the show, but he needed to spend more time with his family as his kids are growing up fast. But even though he’s leaving the show, his legacy remains.
You can watch all the seasons of Shark Tank in the USA on Peacock.
