Who Is Mark Cuban?
Mark Cuban is a billionaire entrepreneur, investor, media owner, and former majority owner of the Dallas Mavericks. His net worth is usually estimated in the $5 billion to $6 billion range, depending on private company valuations and sports assets.
He first became rich through software services, then became a billionaire through streaming media before most people had broadband. Since then, Cuban has built a public profile around sports ownership, Shark Tank dealmaking, and Mark Cuban Cost Plus Drugs, his attempt to make generic prescription pricing easier to understand.
Companies Mark Cuban Founded or Co-Founded
MicroSolutions
MicroSolutions was Cuban’s first major business success. Founded in the 1980s, the company sold software, networking, and systems integration services to corporate clients.
Cuban sold MicroSolutions to CompuServe in 1990. The deal reportedly made him a millionaire and gave him the capital for his next move.
Broadcast.com
Broadcast.com was the company that made Cuban a billionaire. Cuban and Todd Wagner built the business from an early internet audio platform into a streaming media company.
Yahoo bought Broadcast.com in 1999 for $5.7 billion in stock. The timing was perfect for Cuban. The sale happened near the top of the dot-com market, and Cuban protected much of his wealth before the crash.
2929 Entertainment
After Broadcast.com, Cuban and Wagner moved deeper into media. In 2003, they co-founded 2929 Entertainment, a film and entertainment company built around production, distribution, and exhibition.
The company’s current media properties include 2929 Productions, Magnolia Pictures, and Spotlight Cinema Networks. Magnolia Pictures remains the most recognizable name in the group, with a long record in independent film distribution.
AXS TV and HDNet
Cuban founded HDNet in 2001 as an all-high-definition cable network. It later became part of the AXS TV story, focused on music, entertainment, sports, and lifestyle programming.
In 2019, Cuban sold a majority stake in HDNet, the parent company of AXS TV and HDNet Movies, to Anthem Sports & Entertainment. Cuban and AEG continued to hold equity after the deal.
Mark Cuban Cost Plus Drugs
Mark Cuban Cost Plus Drugs is now Cuban’s most important operating company. It launched in 2022 as a public-benefit pharmacy company focused on generic drugs and transparent pricing.
The model is built around showing customers the cost, adding a standard markup, and reducing the hidden layers often associated with pharmacy benefit managers. The company says it uses a vertically integrated supply chain, with manufacturing, wholesale, and pharmacy operations tied into the same price-transparency model.
Does Mark Cuban Still Own the Dallas Mavericks?
Cuban no longer controls the Dallas Mavericks. He bought a majority stake in the NBA team in 2000 for $285 million, then sold the controlling interest to the families of Dr. Miriam Adelson and Sivan and Patrick Dumont in a deal approved by the NBA in December 2023.
It remains one of the clearest examples of his investment style: buy into an undervalued asset, improve the product, then benefit as the market catches up.
Mark Cuban’s Shark Tank Companies
Cuban’s Shark Tank portfolio is large, but it should not be overstated. It is reported that he invested in 85 companies as of November 2024.
His largest Shark Tank deal was Ten Thirty One Productions at $2 million. Other notable names tied to his Shark Tank run include Tower Paddle Boards, Nut’s N More, Prep Expert, and BeatBox Beverages.
Cuban has said Shark Tank deals require time after the cameras stop rolling. Which explains why his role often sits somewhere between investor, advisor, operator, and public amplifier.
Harbinger Sports Partners
Harbinger Sports Partners is Cuban’s newest major sports investment platform. Cuban serves as General Partner and President of Harbinger Sports Partners Fund I.
The fund was created to buy minority stakes in professional sports franchises. It has been reported as targeting $750 million overall, with more than $450 million secured at initial close in 2026.
This is a different kind of sports play from the Mavericks. Instead of buying and running one franchise, Harbinger gives Cuban exposure to multiple teams through smaller ownership positions.
Mark Cuban Companies and the Wider Portfolio
Mark Cuban Companies is Cuban’s main public-facing investment vehicle. Its website lists portfolio companies across AI, apparel, blockchain, consumer products, food, healthcare and biotech, media, productivity, social and civic ventures, and sports.
Some current or associated names include Mark Cuban Cost Plus Drug Company, Burwoodland, VibeRide, Alyssa’s Bakery, Texas Legends, and the Mark Cuban Foundation.
Outside the official company site, investor databases show the scale of Cuban’s angel investing. Tracxn lists 126 investments, including companies such as Polygon and OpenSea, along with 20 portfolio exits and seven unicorns. Those figures make Mark Cuban’s portfolio much broader than his best-known media and sports assets.
Other Notable Mark Cuban Investments
Cuban’s investment activity covers several lanes.
In crypto and Web3, he has been linked to Polygon and OpenSea. In consumer and retail, his portfolio includes companies such as Mad Rabbit, Gameday Couture, and Alyssa’s Bakery. In software and hardware, he has backed companies across enterprise applications, robotics, productivity, and sports data.
Not all of these are controlled companies. Many are minority investments, angel checks, Shark Tank deals, or advisory positions. What stands out is that Cuban’s business empire is not a holding company where he runs every asset. It is a mix of founder-led businesses, co-owned media assets, minority stakes, and public-facing investments where his name can add attention.
What Mark Cuban Invests In
Cuban tends to invest where he sees a broken pricing model, a strong founder, or a market that has not fully adjusted to new technology.
Broadcast.com was about internet media before streaming became normal. The Mavericks were about buying into professional sports before team valuations soared. Mark Cuban Cost Plus Drugs is about price transparency in healthcare. Harbinger Sports Partners extends that same thinking into minority sports ownership.
Cuban likes assets where attention, timing, technology, and pricing gaps meet.
