Mark Cuban’s time as the majority owner of the Mavericks is coming to a shocking conclusion.

Cuban has agreed to sell a majority stake in the NBA franchise to Miriam Adelson, the wife of late casino magnate Sheldon Adelson, at a valuation of approximately $3.5 billion, according to The Athletic’s Shams Charania.

Cuban will retain a minority stake in the team and also still preside over basketball operations, the report said.

Cuban, who made his fortune selling the website broadcast.com to Yahoo in the late 1990’s, bought the team for $285 million in 2000.

The Mavericks won the 2011 NBA championship.
