The Buss family’s decision to sell a controlling stake in the Los Angeles Lakers at a franchise valuation of $10 billion marks the end of nearly a half-century when one of the most valuable properties in the entire sports world was run by an eccentric father and his sometimes squabbling children.

Lakers minority owner Mark Walter is set to take majority ownership in a deal valuing the Lakers at about $10 billion, making it the most expensive U.S. sports team valuation in history. The deal will end family control of the Lakers.

The Los Angeles Lakers will have new majority ownership, selling to Mark Walter, the CEO of TWG Global and controlling owner of the Dodgers.
