Mark Cuban Says Sale of the Dallas Mavericks Could Make the City a 'Tourism Destination' (Exclusive)

The "Shark Tank" star, whose new MasterClass debuts on Thursday, tells PEOPLE that his decision to sell the NBA franchise after nearly 24 years is a nod towards the "future" of sports

Mark Cuban is ready to share the keys to his success!

The billionaire businessman is offering insight into his entrepreneurial mind in a new MasterClass called “Win Big in Business,” which debuted on the platform Thursday.

In an exclusive interview with PEOPLE, the Shark Tank star shares that he took his own advice — “know what you’re good at and focus on those things” — when it came to his landmark decision to sell the Dallas Mavericks last fall.

“I'm good at technology, I'm good at media, I'm good at sales,” Cuban, 65, tells PEOPLE. “Sometimes I'm good at basketball, but what I'm not good at is building arenas or building resort entertainment destinations. That's kind of the future, big revenue streams for professional sports.”

Cuban says he took a cue from another notable figure in North Texas sports — Dallas Cowboys owner Jerry Jones — and realized that he could align himself with new partners (Las Vegas Sands Corp. owners Patrick Dumont and Miriam Adelson) to help make Dallas a tourist destination.

“Just imagine a Venetian next to the convention center in Dallas, that would change everything,” Cuban says, about the possibility of bringing gambling to Texas. “And imagine how, if you think about your friends from outside of Texas, there's not really that one thing that they say, ‘You know what? I'm saving up my money to come to Dallas for A, B or C.’”

He adds, “We're not really a tourism destination at this point. And so I think casino resort gaming would turn Dallas and whatever locations replicated in Texas into probably one of the top three tourist destinations in the country. And so I think it makes sense to happen.”

Cuban believes weighing the challenges and risks of any venture — just like the sale of the Mavs — is a key principle offered in his MasterClass, along with tools to help people who want to carve out their own niche.

It’s a determination which has helped fuel another project, his online discount prescription drug company Cost Plus, which offers “transparency” in pricing and has made inroads as a pharmaceutical wholesaler.

As far as the father of three is concerned, age is nothing but a number when it comes to achieving success.

While his and wife Tiffany’s 14-year-old son Jake has taken an interest in business, their 17-year-old and 20-year-old daughters Alyssa and Alexis are still considering their options.

“They're finding things that they like to do,” Cuban says. “And that's the cool part about being an entrepreneur. You don't have to be young when you start. You don't have to be 17 or 20. You could be 20, 25, 30, 50, 60, 75, it doesn't matter."

He adds, "It just really comes down to when you find that you have a base of knowledge about something that can give you an edge, and you really love that so much that you want to be great at it. Being great at something or really, really good at something is what puts you in a position to start a business.”

After the sale of the Mavs, a team which he owned for nearly 24 years, Cuban has retained a 27% stake.

The numbers may have changed but Cuban’s devotion — he says he’ll continue to travel with the team on road trips — is unwavering.

“I'm still actively involved in the basketball side,” he says. “So yeah, I'm all in on the Mavs still. You'll see me at games yelling and screaming at the refs, yelling and screaming for the Mavs. So that hasn't changed at all.”
