Mark Richard Walter (born January 1, 1960) is an American businessman, philanthropist and the chief executive officer of Guggenheim Partners, a privately held global financial services firm with more than $325 billion in assets under management. He is also the CEO and Co-chairman of TWG Global, an American multinational holding company.
Walter and his wife invest together in numerous philanthropic causes, including the White Oak Conservation,[13] an animal refuge in Florida. Walter bought the facility in 2013 which has cared for many endangered species, including the Florida grasshopper sparrow.[14][15]
Walter leads the Los Angeles Dodgers Foundation, which is committed to promoting education and health in the greater Los Angeles community.[16] He donated $50 million at the start of the 2024 season and an additional $50 million when the Dodgers made it to the World Series.[17]
In 2025 he became a leader of LA Rises, a fundraising group assigned by California Governor Gavin Newsom to support rebuilding after the area's wildfires early in the year. Walter organized the first $100 million donation.[20]
Business history
Walter is notoriously private,[3] and estimates of his wealth vary wildly. In May 2024, Bloomberg Businessweek estimated that Walter's net worth was $6 billion.[21] However, in October 2024, Bloomberg raised the estimate to $12 billion,[22] on the assumption that Walter owned 20% of Guggenheim Partners.[23] As of February 2025, Forbes valued Walter's net worth at $6.1 billion.[4]
In 1996, Walter, Tom Irvin and Steven E. Johnson co-founded the Liberty Hampshire Company.[24] In 2000, he helped found Guggenheim Partners with assistance from Guggenheim family heir Peter Lawson-Johnson II;[3] he now serves as its CEO.[25] Through his work at Guggenheim, he got to know future investment partner Todd Boehly, who spent 14 years with the firm.[26]
As of 2025, Walter is the CEO, Co-chairman and 21% owner of TWG Global,[23][27] which has significant holdings in the insurance and financial services industries including 19% of Group 1001, a company that owns various insurance companies.[28][23] He is the controlling shareholder of Delaware Life Holdings, LLC, and serves on the board of EquiTrust Life.[29] TWG Global also invests in energy, sports and entertainment, artificial intelligence and other technology and merchant banking services, including a stake in Carvana.[23]
Walter has a personal stake in Beyond Meat.[4] In addition, in 2021, it was reported that Walter had purchased numerous commercial and historic buildings in Crested Butte, Colorado, where his family frequently vacations,[3] for an unknown purpose.[30][31]
In April 2025, TWG Global announced a strategic alliance with Mubadala Capital, a subsidiary of Abu Dhabi sovereign wealth fund Mubadala Investment Company. Mubadala coordinated a $10 billion investment in TWG, and TWG concurrently acquired a 5% stake in Mubadala Capital for $2.5 billion.[32] TWG concurrently asserted that its current enterprise value was "over $40 billion".[33]
Sports investments
Business model
According to the Los Angeles Times, Walter utilized financial firepower from various Guggenheim-related insurance funds to buy the Los Angeles Dodgers in 2012.[34] The Guggenheim insurers frequently deal in annuities, which provide large amounts of upfront capital but commit the insurers to long-term payment calendars.[35] Walter frequently co-invests with Todd Boehly, a former Guggenheim employee who helped Walter's Guggenheim Partners acquire annuity specialist Security Benefit and bought the company from Guggenheim in 2015.[36] According to Boehly, his investment business creates or buys cash-needy companies, which Security Benefit's cash flow helps grow. Provided that the companies actually turn a profit, these profits can then be used to fund Security Benefit's annuities. Boehly earns money, in part, by buying stakes in the companies, which appreciate in value due to the investment from Security Benefit.[37]Forbes noted that other investors, like Warren Buffett (whose Berkshire Hathaway company owns insurer GEICO), have used similar tactics to make investments and acquisitions, although it added that Buffett "prefers mundane businesses like truck stops and ketchup."[36]
Because of their long-term payment horizon, insurers that sell annuities are expected to prioritize long-term financial stability.[35] As such, Guggenheim's investments in sports have sometimes been questioned by industry commentators. When Walter bought the Dodgers in 2012, The New York Times' Andrew Ross Sorkin wrote a critical column opining that insurance companies ordinarily do not invest in comparatively risky assets like sports franchises.[38] After insurers reportedly contributed at least $300 million to the Dodgers bid, government regulators investigated the arrangement but declined to take further action.[39] In addition, in 2015, a representative from the Consumer Federation of America said that he would prefer to see a more conservative strategy from the Guggenheim insurers. By controlling multiple insurance companies, Guggenheim freshens up the balance sheets of each insurer by arranging for one insurer to provide reinsurance for the others, a practice that Guggenheim has defended as regulator-approved. Guggenheim has also struck a reinsurance deal with a company owned by a Dodgers investor.[35]
Following early qualms, Guggenheim's financial position was strengthened by high television rights fees, as "live sports programming has proven far more resistant to disruption from the likes of Netflix and Amazon than other entertainment fare such as TV series and films."[40] In buying the Dodgers, Walter intentionally broke with the conventional wisdom that National Football League franchises were more valuable than baseball teams, pointing out that the NFL does not allow teams to own their own television broadcasting rights.[41] In addition, Walter and his business associates have provided collateral to the insurers, including Dodgers shares, Walter's stake in Carvana, and various Wendy's hamburger franchises.[39] Sorkin has acknowledged that Guggenheim's investment principles are not unique, as "many insurance companies use their premiums to make investments ... a slice of which can sometimes even be speculative," and that insurance companies ordinarily comply with the law if they "meet minimum capital requirements as determined by various regulators."[38][42]
Walter also uses sports to advertise his insurance companies, particularly TWG Global subsidiary Gainbridge. Gainbridge is headquartered in Zionsville, Indiana,[43] and advertises extensively in the state. It is heavily associated with IndyCar, where it has sponsored racing team Andretti Global since 2018; Walter now owns the Andretti outfit.[44][45] In 2019, Gainbridge became the presenting sponsor of the Indianapolis 500.[44] In 2021, it bought the naming rights to the Indiana Pacers and Indiana Fever's home arena, now known as Gainbridge Fieldhouse.[46] It also signed Fever basketball player Caitlin Clark as a brand ambassador in 2024.[47] Gainbridge also devotes sponsorship dollars to women's sports, often in conjunction with Walter's franchises and business partners like Billie Jean King.[48]
Los Angeles sports teams
Los Angeles Dodgers
According to a family representative, Walter owns 27% of the Los Angeles Dodgers baseball team.[23] In 2012, he led Guggenheim Baseball Management (GBM)'s $2.15 billion purchase of the team.[49] His personal contribution was reportedly $100 million,[50] with Guggenheim Partners-related businesses contributing another $1.213 billion.[51] (The precise contribution from insurance companies has been disputed, with The Wall Street Journal estimating a contribution of "at least $300 million"[39] and LA Weekly putting the figure at $100 million.[35]) He had previously looked into buying the Houston Astros.[52]

The price paid for the Dodgers was initially described as "stunning,"[49] as Forbes had valued the team at $1.4 billion and rivals were considering opening bids in the $1.6 billion range.[53] However, journalist Molly Knight later revealed that Steven A. Cohen (who later bought the New York Mets) had already offered Dodgers owner Frank McCourt $2 billion.[54] Walter explained that he opened with his best bid so that McCourt would call off his auction for the Dodgers,[49] which was scheduled for the following day.[55] In March 2024, Forbes valued the Dodgers at $5.45 billion.[56]
Walter appointed Stan Kasten to run the team.[34] Under Walter, Kasten, and president of baseball operations Andrew Friedman,[57] the team became baseball's "most perennially competitive team,"[22] and won the World Series in 2020 and 2024.[58] Less than a year after GBM bought the team, the Dodgers signed the most lucrative television deal in baseball.[59] Aided by the TV deal, the Dodgers significantly increased their payroll, which had previously been constricted by McCourt's cash flow issues.[34] Although the Dodgers have not always been the year's biggest spender,[60] Walter greenlighted spending sprees in 2012 (when the Dodgers "easily" set the MLB single-season payroll record for the next season),[61] 2023 (when the team signed $1.145 billion in contracts),[62] and 2024 (when the team added four nine-figure contracts in fewer than 12 months).[63]
Walter is the incoming majority owner of the Los Angeles Lakers basketball team.[67] In 2021, he purchased 20% of the team from Philip Anschutz, teaming up with Todd Boehly to buy out Anschutz's 27% stake for $1.35 billion, or a $5 billion valuation.[23][68] On June 18, 2025, ESPN reported that Walter had agreed to buy majority control of the team from the Buss family at a $10 billion valuation.[67] The Los Angeles Times reported that TWG Global would also be involved in the purchase.[69] The deal was well received, including positive commentary from Magic Johnson praising Walter as "the right person" to lead the team.[70] ESPN analyst Ramona Shelburne also called Walter "one of the savviest investors in the world'" in an interview about the sale.[71]
Los Angeles Sparks
Since 2014, Walter and Magic Johnson have led the ownership group for the Los Angeles Sparks women's basketball team.[72] Walter personally owns one-sixth of the franchise,[23] which he co-owns with several other Dodgers partners.[73] He credited Johnson with giving him the idea to "save the Sparks and keep them in Los Angeles."[72] The Sparks won the 2016 WNBA championship and made the 2017 WNBA Finals.[74]
Walter owns 12.7% of BlueCo,[23] a holding company that bought English Premier League football club Chelsea in 2022 and Ligue 1 club RC Strasbourg Alsace in 2023.[26] BlueCo is primarily owned by Clearlake Capital (represented by Behdad Eghbali and José E. Feliciano), and Eghbali is the primary figure at BlueCo, but Walter's investment partner Todd Boehly has a veto over major decisions.[26] Walter serves on Chelsea's board,[78] but does not play an active role in day-to-day operations.[26]
Walter appointed the Dodgers' Stan Kasten to oversee the league's business operations,[84] and reportedly "committed hundreds of millions of dollars to launch the league,"[81] which began play in 2024.[79] The Mark Walter Group owns the inaugural six teams,[85][86] although the PWHL has not ruled out adding expansion teams.[87] The league's championship trophy is named after Mark and Kimbra Walter.[81]
Squash
Walter and his wife were the primary financial backers of the 2018–19 PSAWorld Squash Championships; with their help, the event presented its largest winners' purses in history. They continue to back the event, as well as the Windy City Open.[88]
