The Boston Celtics were the last NBA team to be sold when they struck a deal with a group led by Bill Chisholm earlier this year. The group purchased the Celtics for $6.05 billion, which set an NBA record. Controlling ownership of both the Phoenix Suns and Dallas Mavericks were sold in recent years, too.

Walter owns the WNBA’s Los Angeles Sparks, the newly formed Cadillac Formula One team, and the Professional Women’s Hockey League.

The Buss family has agreed to sell the controlling stake of the Los Angeles Lakers to TWG Global CEO Mark Walter, doing so with a franchise valuation of $10 billion — the most ever for a professional sports franchise, a person with knowledge of the agreement said Wednesday.
