Mark Cuban is the Shark Tank investor who is a co-owner of the NBA team Dallas Mavericks.
Cuban purchased a majority stake in the Mavericks in January 2000, buying the team from Ross Perot Jr. His ownership made him one of the most visible team owners in American professional sports, particularly because of his outspoken courtside presence and media interviews.
Cuban joined Shark Tank as a guest investor during the show's second season and became a regular Shark afterward. His technology background and willingness to make large offers quickly made him one of the program's most recognizable investors.
The Mavericks fact is sometimes confused with Cuban's ownership of other sports ventures. He has also been involved in sports media and entertainment, but the Dallas Mavericks are his best-known major-league team holding.
