Sports Empire of Mark Walter

Walter is now one of the most influential sports owners in the world. Here’s a look at the teams he owns or has invested in:

⚾ Los Angeles Dodgers: According to a family spokesperson, Walter owns 27% of the Los Angeles Dodgers baseball team.

Back in 2012, he led a group called Guggenheim Baseball Management (GBM) in buying the team for $2.15 billion, which was a record-breaking amount at the time.

Walter personally put in $100 million of his own money. Companies connected to Guggenheim Partners added another $1.213 billion to the deal.

Some of that money may have come from insurance companies, but the exact amount is unclear.

• The Wall Street Journal estimated they gave at least $300 million,
• On the other hand, LA Weekly said it might have been just $100 million.

Before buying the Dodgers, Walter had also shown interest in purchasing the Houston Astros.

🏀 Los Angeles Lakers: Walter is set to become the new majority owner of the Los Angeles Lakers, a famous NBA basketball team.

Back in 2021, he bought a 20% share of the team from Philip Anschutz. He worked with Todd Boehly to help purchase a total 27% stake for $1.35 billion, which meant the team was valued at around $5 billion at that time.

Then, on June 18, 2025, ESPN reported that Walter had made a deal to buy majority ownership of the Lakers from the Buss family, who have controlled the team for decades. This new deal values the team at $10 billion.

“ Mark Walter’s leadership in both business and sports is unmatched. The Lakers are in powerful, patient hands.” – Anonymous NBA executive

🏀 Los Angeles Sparks: Since 2014, Walter and Magic Johnson have been the main leaders of the group that owns the Los Angeles Sparks, a women’s professional basketball team.

Walter himself owns one-sixth (about 16.7%) of the team. He shares ownership with a few of his business partners from the Los Angeles Dodgers baseball team.

Walter said that it was Magic Johnson’s idea to help save the Sparks and make sure the team stayed in Los Angeles.

Their support paid off—the Sparks won the WNBA championship in 2016 and reached the finals again in 2017.

🏎 Motorsports: Walter is part-owner of several racing teams through his company TWG Global and its branch TWG Motorsports. Here’s a simple breakdown of the teams he’s involved with:

• Andretti Global – This team competes in open-wheel racing, including IndyCar, Indy NXT, and Formula E.
• Cadillac Formula 1 Team – A new Formula One team that plans to start racing in the 2026 F1 World Championship.
• Spire Motorsports – This team races in stock car and truck events, like the NASCAR Cup Series, NASCAR Truck Series, and ARCA.
• Walkinshaw Andretti United – A team that competes in Australia’s Supercars Championship.
• Wayne Taylor Racing – Focuses on sports car racing, including the IMSA SportsCar Championship.

In short, Walter is deeply involved in various types of motorsport through these teams—ranging from Formula 1 and NASCAR to electric and endurance racing.

⚽ European football ownership (Chelsea, Strasbourg): Walter owns 12.7% of BlueCo, a company that bought two major soccer teams: Chelsea FC in England (in 2022) and RC Strasbourg Alsace in France (in 2023).

BlueCo is mostly owned by Clearlake Capital, led by Behdad Eghbali and José E. Feliciano. Eghbali is the main decision-maker in the company. However, Walter’s business partner, Todd Boehly, has the power to veto (block) any major decisions BlueCo makes.

Walter is a board member at Chelsea, meaning he helps with high-level decisions, but he is not involved in the team’s daily operations or management.

🏒 Women’s Ice Hockey: Mark Walter owns the Professional Women’s Hockey League (PWHL), which is now the top women’s pro hockey league in North America.

He worked with Billie Jean King and Ilana Kloss, who are also connected to the L.A. Dodgers, to create one united league. To do this, they combined two rival groups:

• The Professional Women’s Hockey Players Association (PWHPA)
• The remains of the Premier Hockey Federation (PHF)

This merger ended a long-standing conflict. The PWHPA had refused to play in the PHF, asking for more serious investment in women’s hockey. Walter’s group brought them together under one league.

He also brought in Stan Kasten, president of the Dodgers, to run the league’s business side. Reports say Walter invested hundreds of millions of dollars to launch the league, which officially began playing in 2024.

The Mark Walter Group owns the league’s first six teams, and there may be more teams added in the future. The league’s championship trophy is named after Mark and his wife, Kimbra Walter, in recognition of their support.

🎾 Squash: Walter and his wife gave most of the money needed to support the 2018–19 PSA World Squash Championships. Thanks to their help, the tournament was able to offer the biggest prize money in its history.

They have continued to support this squash event and also help fund another major tournament called the Windy City Open.
