The Guggenheim insurers frequently deal in
annuities, which provide large amounts of upfront capital but commit the insurers to long-term payment calendars.
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.
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. ''

Andrew Ross Sorkin wrote a critical column opining that insurance companies ordinarily do not invest in comparatively risky assets like sports franchises.
After insurers reportedly contributed at least $300 million to the Dodgers bid, government regulators investigated the arrangement but declined to take further action.
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

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

than other entertainment fare such as TV series and films." 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. 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.
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."

Walter appointed
Stan Kasten to run the team.
Under Walter, Kasten, and president of baseball operations
Andrew Friedman, the team became baseball's "most perennially competitive team,"
and won the World Series in
2020 and
2024. Less than a year after GBM bought the team, the Dodgers signed the most lucrative television deal in baseball. Aided by the TV deal, the Dodgers significantly increased their payroll, which had previously been constricted by McCourt's cash flow issues.
Although the Dodgers have not always been the year's biggest spender, Walter greenlighted spending sprees in 2012 (when the Dodgers "easily" set the MLB single-season payroll record for the next season), 2023 (when the team signed $1.145 billion in contracts), and 2024 (when the team added four nine-figure contracts in fewer than 12 months).
Other members of the Guggenheim consortium include
Peter Guber,
Earvin “Magic” Johnson,
Stan Kasten,
Todd Boehly,
Bobby Patton,
Billie Jean King,
Ilana Kloss,
Alan Smolinisky, and Robert L. Plummer.
Basketball
Walter owns one-sixth of the
Los Angeles Sparks women's basketball team,
which a group of Dodgers partners bought in 2014. The
WNBA's press release described Walter and Magic Johnson as the leaders of the ownership group. After buying the team, Walter commented that Johnson "came to me and said we need to help save the Sparks and keep them in Los Angeles." The Sparks won the
2016 WNBA championship and made the
2017 WNBA Finals. Beyond the Sparks, a Group 1001 subsidiary signed
Caitlin Clark as a brand ambassador in March 2024, shortly before the
2024 WNBA draft.
Walter owns 20% of the
Los Angeles Lakers men's basketball team.
In 2021, he teamed up with Boehly to buy out
Philip Anschutz's 27% stake for an estimated $1.35 billion. Walter and Boehly reportedly have a right of first refusal if the
Buss family ever sells the team. Walter had previously joined
David Geffen,
Oprah Winfrey, and
Larry Ellison's unsuccessful 2014 bid for the
Los Angeles Clippers, which eventually went to
Steve Ballmer.
Hockey
Walter once led a consortium that bid for
Anschutz Entertainment Group, which owns the
Los Angeles Kings and is the
Lakers' landlord, but Philip Anschutz decided to keep the company.

The purchase ended the PWHPA's boycott of the PHF, which the PWHPA was pressuring to invest more in the sport.
Walter appointed the Dodgers' Stan Kasten to oversee the league's business operations, and reportedly "committed hundreds of millions of dollars to launch the league,"
which began play in 2024.
The Mark Walter Group owns the inaugural six teams,
although the PWHL has not ruled out adding expansion teams. The league's
championship trophy is named after Mark and Kimbra Walter.
Squash
Walter and his wife were the primary financial backers of the 2018-19
PSA World 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.
