LOS ANGELES–Billionaire Mark Walter’s purchase of a majority stake in the Los Angeles Lakers, in a deal that values the team at $10 billion, adds another glittering asset to his sports portfolio and could usher in another championship era for the National Basketball League franchise.

For just under $10 billion, private equity firm 3G Capital recently bought Skechers — an ascendant global footwear brand with $9 billion in annual sales and 20,000 employees spread across 5,300 stores.
