Mark Cuban's Companies & Ventures
A deep dive into Mark Cuban's story — Broadcast.com, Dallas Mavericks, Cost Plus Drugs, Shark Tank, United States.
Mark Cuban's entrepreneurial career spans four decades and includes some of the most consequential business moves in modern history.
It started with MicroSolutions in 1983, a computer consulting firm he founded after being fired from his retail job. He built it to $30 million in revenue before selling to CompuServe for $6 million — his first taste of a liquidity event.
Broadcast.com, co-founded with Todd Wagner in 1995, was the company that changed everything. Originally called AudioNet, it was one of the first platforms to stream live audio and video over the internet. When Yahoo acquired it in 1999 for $5.7 billion, Cuban became one of the wealthiest people in America overnight. His decision to hedge the Yahoo stock he received — rather than riding the dot-com wave — preserved his fortune when the bubble burst.
The Dallas Mavericks, purchased for $285 million in 2000, became Cuban's most visible venture. He transformed a perennial loser into a championship franchise, earning an NBA title in 2011. His passionate, courtside presence and willingness to get fined by the NBA for speaking his mind made him the most famous owner in professional sports. The franchise appreciated to over $4 billion in value.
Shark Tank gave Cuban a platform to invest in hundreds of startups across every imaginable industry, from tech to food to fitness. His investments on the show generated returns and, more importantly, inspired a generation of entrepreneurs.
Cost Plus Drugs, launched in 2022, may be his most important venture. By selling generic medications at cost plus a transparent 15% markup, Cuban challenged the opacity of pharmaceutical pricing and made essential drugs affordable for millions of Americans.
