Early Life: Garbage Bags and Determination
Mark Cuban grew up in Pittsburgh, Pennsylvania in a working-class family. His entrepreneurial instinct showed early: at age 12, he sold garbage bags door-to-door to pay for a pair of basketball shoes his parents wouldn’t buy. By high school, he was selling stamp collections and running a small business. He enrolled at Indiana University and famously opened a bar — Motley’s Pub — while still a student, before graduating with a degree in business administration in 1981.
After college, he moved to Dallas and was fired from his first job at a software company on the same day he planned to close a major account. Rather than return to employment, he started MicroSolutions, a computer consulting firm, which he sold to CompuServe in 1990 for $6 million, netting around $2 million after taxes — his first big win.
The Broadcast.com Deal — $5.7 Billion from the Internet Bubble
Cuban’s wealth-defining moment came in the mid-1990s when he co-founded AudioNet with Todd Wagner. The company, which streamed live radio and other audio content over the internet, rebranded as Broadcast.com and went public in 1998 in one of the most spectacular IPOs of the dot-com era — the stock rose 250% on its first day. In April 1999, at the absolute peak of the internet bubble, Yahoo acquired Broadcast.com for $5.7 billion in Yahoo stock. Cuban immediately began hedging his Yahoo position through a complicated collar strategy. When the dot-com bubble burst in 2000-2001, Cuban had already locked in billions.
The Dallas Mavericks Era
In January 2000, Cuban purchased a 73% stake in the Dallas Mavericks for $285 million. What followed was a 23-year transformation of one of the NBA’s most dysfunctional franchises. Cuban invested heavily in player acquisition, facilities, and the fan experience. The Mavericks won the NBA Championship in 2011, defeating the Miami Heat in six games. In 2023, Cuban agreed to sell a majority stake to Miriam Adelson for approximately $3.5 billion, while retaining a minority share — representing one of the most profitable sports franchise investments in history.
Cost Plus Drugs and Current Ventures
Since selling the Mavericks majority stake, Cuban has thrown himself into his pharmaceutical disruption venture, Cost Plus Drugs (also known as Mark Cuban Cost Plus Drug Company). Launched in 2022, the company offers generic drugs at dramatically reduced prices by cutting out pharmaceutical middlemen. By 2025, the company was filling over 1 million prescriptions monthly and was valued by analysts at between $500 million and $1 billion.
