You’ve probably seen the guy screaming from the sidelines at a Dallas Mavericks game, or maybe you’ve watched him ruthlessly tear apart a bad pitch on Shark Tank. Mark Cuban is a lot of things. Brash? Definitely. Wealthy? Obviously. But if you're asking what is Mark Cuban known for today, the answer isn't as simple as "the basketball guy" or "the guy from TV."
Honestly, he’s one of the few billionaires who actually seems to enjoy being famous. He doesn't hide on a yacht in the Mediterranean. He's on X (formerly Twitter) arguing about drug prices or appearing on podcasts to talk about why he sold his majority stake in the Mavs. His life is basically a masterclass in how to fail forward until you hit a $5.7 billion lottery ticket.
The Dot-Com Jackpot That Changed Everything
Before he was a household name, Mark Cuban was just a guy with a computer consulting business called MicroSolutions. He sold that for a few million, which is great, but it wasn't "buy a private jet" money. The real pivot happened in the late 90s.
Ever heard of Broadcast.com?
If you haven’t, don't worry—it doesn't exist anymore. But in 1999, it was the hottest thing on the internet. Cuban and his partner Todd Wagner figured out how to stream radio over the web so they could listen to Indiana University basketball games in Texas. It sounds basic now, but back then, it was revolutionary.
They took the company public, the stock went to the moon, and then—in what is widely considered the best-timed sale in business history—they sold it to Yahoo for $5.7 billion.
- Timing is everything: Cuban sold right before the dot-com bubble burst.
- Hedged his bets: He used complex financial maneuvers to protect his Yahoo stock value.
- Instant Billionaire: He went from "doing okay" to one of the richest people on the planet almost overnight.
Yahoo eventually shut down Broadcast.com. It’s often cited as one of the worst acquisitions ever for Yahoo, but for Cuban? It was the ultimate launchpad.
The Face of the Dallas Mavericks
For over two decades, if you thought of the Dallas Mavericks, you thought of Mark Cuban. He bought the team in 2000 for $285 million. At the time, the Mavs were kind of a joke. They were losing games, the arena was empty, and nobody cared.
Cuban changed the culture by being the "fan-owner." He sat in the stands, wore team jerseys, and racked up millions of dollars in fines for yelling at referees. He treated the players like royalty, upgrading the locker rooms and the team plane long before other owners realized that happy players play better.
The peak came in 2011. Under Cuban's watch, and led by Dirk Nowitzki, the Mavericks beat the "Big Three" Miami Heat (LeBron, Wade, and Bosh) to win the NBA Championship.
Fast forward to late 2023, and Cuban shocked the sports world by selling his majority stake to the Adelson family for roughly $3.5 billion. He kept a minority share (around 27%), but he’s no longer the guy calling every single shot. He recently admitted on a podcast that he regrets how he sold it—specifically that he didn't put it up for a public bidding war—but he stands by the decision to move on.
Shark Tank and the "Shark" Persona
Since 2011, a huge part of what is Mark Cuban known for is his seat on the Emmy-winning show Shark Tank. He wasn't even in the first season, but once he joined, he became the show's gravity.
Cuban is the Shark that entrepreneurs want the most. He’s known for the "24-second clock"—forcing people to make a decision right now or he’s out. He’s invested nearly $20 million across hundreds of deals on the show.
Interestingly, he's been open about the fact that he's actually lost money on his Shark Tank portfolio as a whole. Some deals like Rugged Maniac and Ten Thirty One Productions were winners, but many others fizzled out. For him, the show was more about the "sport" of business and helping people chase the American dream. He officially left the show in 2025, marking the end of a massive era for reality TV.
Disrupting Big Pharma with Cost Plus Drugs
If you ask Mark Cuban today what he wants to be his legacy, he won't say basketball or TV. He’ll say Cost Plus Drugs.
Launched in 2022, the Mark Cuban Cost Plus Drug Company is a direct attack on the "opaque middlemen" of the pharmaceutical industry. The model is simple:
- They buy drugs directly from manufacturers.
- They charge a flat 15% markup.
- They add a $5 pharmacy fee and shipping.
That’s it. No hidden rebates. No confusing insurance tiers.
There are stories of people saving thousands of dollars a month on life-saving medications like Imatinib (a leukemia drug). In a 2026 landscape where healthcare costs are still a political nightmare, Cuban’s pharmacy is one of the few things both sides of the aisle seem to think is actually working. He’s used his fame to shine a light on Pharmacy Benefit Managers (PBMs), basically calling them parasites that drive up prices for no reason.
The "Controversial" Public Intellectual
Cuban doesn't have a filter, and that gets him into trouble. Whether it’s his recent political sparrings or his 2024 comments on The View about Donald Trump and "strong, intelligent women" (which he later tried to clarify), he’s always in the headlines.

He’s also been a massive proponent of Cryptocurrency, though he took a hit when the platform Voyager collapsed. He’s someone who isn't afraid to be wrong in public. That’s sort of his brand. He’d rather be loud and corrected than quiet and safe.

Actionable Takeaways from Cuban’s Career
Mark Cuban’s life isn't just about being lucky with the internet bubble. There are actual lessons here if you're trying to build something.
First, transparency is a competitive advantage. Cost Plus Drugs is winning because it tells you exactly why things cost what they cost. In an era of AI and "fake" everything, being real is a superpower.
Second, know when to sell. Cuban sold MicroSolutions when he felt the market was right. He sold Broadcast.com at the absolute peak. He sold the Mavericks when the NBA’s financial structure shifted toward real estate and gambling—areas he didn't want to manage.
If you're looking to follow his lead, start by looking at your own "middlemen." Where is there unnecessary complexity in your industry? That’s where the opportunity is. You don't need a billion dollars to start, but you do need to be willing to read the manuals—just like Cuban did when he was teaching himself software in the 80s.
