Mark Walter is entering an agreement to buy the NBA's Los Angeles Lakers from the Buss family at a valuation of $10 billion dollars. Walter already owns a 20% stake in the Lakers from a previous transaction in 2021, which included the right of first refusal if the Buss family ever chose to sell the team.

The $10 billion valuation is the largest ever for a United States sports team. The figure tops the just over $6 billion valuation for the Boston Celtics when they were recently sold.

Dr. Jerry Buss purchased the Lakers in 1979 for $67.5 million. Jeanie Buss will reportedly continue as the team's governor after the sale goes through.

Walter also owns MLB's Los Angeles Dodgers. He owns interests in other sports franchises, as well. That includes the WNBA's LA Sparks, Chelsea of the English Premier League and North America's primary women's hockey league, the PWHL. In addition, Walter owns several auto racing groups, including the new Cadillac Formula 1 Team that will begin racing in F1 in 2026.
