Mark Cuban to Sell Majority Stake in Dallas Mavericks to Miriam Adelson

Mark Cuban, owner of the Dallas Mavericks, is selling a majority stake of the team to billionaire Miriam Adelson and her son-in-law Patrick Dumont. Cuban will retain control of the franchise despite selling the majority share. Adelson, the largest shareholder of Las Vegas Sands, is purchasing into the Mavericks at a valuation of $3.5 billion. The goal is to build a new arena for the team in partnership with Las Vegas Sands, although sports betting and casinos are currently illegal in Texas. Cuban, who bought the Mavericks in 2000, plans to leave the show "Shark Tank" after its 16th season next year.
