The Mark Walter SEC investigation has drawn federal scrutiny to a financial structure that routed billions of dollars in insurance money through companies the billionaire sports owner controlled, regulators say.
Walter, the controlling owner of the Los Angeles Dodgers, sold his majority stake in the Lakers basketball franchise for $12.5 billion amid the federal probe into his insurance businesses, according to the Los Angeles Times.
The Securities and Exchange Commission (SEC) probe, first reported by Bloomberg in July from regulatory filings, examines whether companies tied to Walter’s empire improperly handled billions of dollars in loans from insurance companies he separately controls. No criminal charges have been filed. The investigation does not allege wrongdoing by the Dodgers or the Lakers.
Walter did not respond to a request for comment. Guggenheim Partners declined to comment.
Mark Walter SEC investigation: the insurance figures restated
At the centre of the inquiry are two insurers, Delaware Life Insurance Co. and Clear Spring Life and Annuity Co. Both conducted internal reviews after receiving federal grand-jury subpoenas and significantly restated prior financial reporting.
Transactions between related parties were not $1.4 billion, or 3% of investments, as previously disclosed. The restated figure stood at over $17 billion, representing at least 39% of total invested assets.
Related-party transactions are not inherently illegal, but they are subject to disclosure and regulatory scrutiny, particularly for insurers that hold money intended to pay policyholders’ future claims.
Delaware Life subsequently agreed to reduce its exposure to Walter-connected businesses by swapping as much as $6.5 billion of related-party investments for assets classified as independent.
More than $1.2 billion of the financing for Walter’s purchase of the Dodgers came from insurance companies he controlled through Guggenheim, according to a breakdown of the transaction by the Los Angeles Times.
A mainstream playbook now under stress
The Mark Walter SEC investigation sits inside a broader pattern in private markets. The private credit market, covering loans and debt financing extended by non-bank lenders, grew to more than $1 trillion in the US in 2023, according to the Federal Reserve Bank of Boston.
The risk flagged by regulators and the International Monetary Fund (IMF) is not private credit itself, but structures where the same firm sits on multiple sides of a deal: a private-credit firm takes in premium money via an insurer it controls, then directs that money into loans it originates or that flow back to its own portfolio companies.
Walter’s case illustrates that model. His insurers held private-credit investments connected to other Walter-controlled businesses, meaning the same owner sat on multiple sides of the same transaction.
Apollo has built a similar structure through Athene, its retirement-services and insurance business. Jim Belardi, chief executive of Athene, said in a January 2022 press release when the firms merged: ‘Athene and Apollo have seen tremendous mutual benefit from our longstanding strategic relationship, and now with full alignment our value will be significantly stronger than the sum of our parts.’
Yankee Global Enterprises, meanwhile, announced a $2.6 billion financing arrangement with affiliates of Apollo Sports Capital. The deal combines credit and equity and will be used to support the growth of the New York Yankees and refinance existing debt.
KKR acquired a majority stake in Global Atlantic in 2021 and the remaining stake in 2024. KKR separately agreed in February to acquire Arctos Partners for about $1.4 billion, a specialist sports investment firm with minority interests in franchises including the NFL’s Buffalo Bills, describing the deal as a way to establish a sports platform while expanding its insurance capital network.
A 2025 Federal Reserve Bank of Chicago working paper estimated private credit accounted for about $849 billion, or 14%, of life insurers’ balance sheets in 2024. Life insurers favour private credit because their liabilities can stretch decades into the future, making long-duration loans attractive. The Federal Reserve Bank of Boston notes insurers are typically less exposed to traditional liquidity risk than banks, though certain annuities and institutional funding products can still be vulnerable.
The Wall Street Journal has reported Walter has been trying to unwind portions of his empire amid the investigation, potentially including the Dodgers and Cadillac’s Formula One operation. Whether Delaware Life’s $6.5 billion asset swap satisfies regulators will be the investigation’s next concrete test.
