Mark Cuban

Mark Cuban (born July 31, 1958) is an American billionaire entrepreneur, investor, and former majority owner of the NBA's Dallas Mavericks, recognized for his success in technology startups, sports management, and direct-to-consumer pharmaceuticals.

Cuban co-founded the streaming media company Broadcast.com in 1995 with Todd Wagner and sold it to Yahoo for $5.7 billion in stock in 1999, a transaction that propelled him to billionaire status amid the dot-com boom.

In 2000, he acquired the Dallas Mavericks for $285 million, guiding the team to its inaugural NBA championship in 2011, before divesting a 73% controlling interest to the Adelson family for $3.5 billion in 2023 while retaining a 27% stake and authority over basketball operations.

From 2011 to 2025, Cuban appeared as a lead investor on ABC's Shark Tank, deploying approximately $33 million into pitches that yielded mixed returns, with some deals underperforming relative to his overall portfolio.

He launched the Mark Cuban Cost Plus Drug Company in 2022 to undercut traditional pharmacy pricing on generic medications by eliminating middlemen markups, expanding into partnerships like TrumpRx by 2025.

As of October 2025, Forbes estimates Cuban's net worth at $6 billion, derived largely from early tech exits, Mavericks appreciation, and diversified investments, though he has acknowledged hundreds of millions in losses from sports ownership due to operational costs.

Cuban frequently comments on business and policy, supporting Kamala Harris in 2024 while critiquing Democratic messaging as insufficiently focused on economic growth and indicating he would pursue a Republican candidacy if entering politics, emphasizing pragmatic incentives over ideology.
