The Lakers’ new era of ownership hit its first turbulence Monday. Federal prosecutors are investigating potential financial improprieties at two insurance companies owned by Mark Walter, the controlling owner of the Lakers, as well as at Guggenheim Partners LLC, where Walter serves as chief executive, according to a Bloomberg report by Zachary Mider and Ava Benny-Morrison.
Before going further, the essential framing: an investigation is not a charge, no charges have been filed against Walter or any of his companies, and nothing in the reporting alleges any wrongdoing by the Lakers or any of Walter’s teams. What follows is what the report actually says, what it does not say and why it matters to a fan base that watched this ownership group take control of the franchise less than a year ago.
What the Bloomberg report says
According to Bloomberg’s reporting, the investigation centers on two insurance companies at the core of Walter’s business empire — Delaware Life Insurance Co., which held $69 billion in assets as of March, and Clear Spring Life and Annuity Co., which held $16 billion — along with Guggenheim Partners itself. Both insurers received grand jury subpoenas in February, a detail that surfaced through previously unreported regulatory filings the companies made on June 26.
Per those filings, prosecutors in Manhattan have asked about the companies’ failure to disclose that billions of dollars of their private credit holdings backed other parts of Walter’s business ventures — in plain terms, a question about whether investments involving related parties were properly characterized. The companies said the investigation is running in parallel with a separate inquiry by the U.S. Securities and Exchange Commission.
Bloomberg also reported that the subpoenas followed inquiries by prosecutors last year into Guggenheim’s $362 billion money-management arm, including questions about representations the company made to outside parties about its revenue, and that the current status of that portion of the probe is unclear. The report added that the FBI executed at least one search warrant in September to seize a mobile phone.
In statements carried in the report, TWG Global — Walter’s holding company — said it is “aware of and cooperating with the investigation,” and the parent company of the two insurers said its capital position, liquidity and financial strength ratings are unchanged.
What the report does not say
This section matters as much as the one above it. The Bloomberg report does not allege any wrongdoing by the Lakers, the Dodgers, the Sparks or any of Walter’s sports properties, and none of those franchises is described as a subject of the investigation. It does not report charges against Walter or any of his companies, and a grand jury subpoena is an investigative tool, not an accusation — many federal inquiries end without any charges at all.
There is also no indication in any of Monday’s reporting that the NBA has taken or is considering any action, and no reporting connects the investigation to the league’s approval of Walter’s purchase of the team. Anything beyond that is speculation, and this story has attracted plenty of it on social media within hours.
The facts, for now, are narrow: Two insurance companies and an asset manager are being investigated, the companies say they are cooperating and no outcome of any kind has been reached.
Who Mark Walter is and how he came to own the Lakers
For fans still getting acquainted with the man who now controls the franchise, Walter is the chairman and chief executive of TWG Global and the CEO of Guggenheim Partners, and he has been the controlling owner of the Dodgers since 2012.
His path to the Lakers ran through a decade of patience: He first bought a minority stake of about 26 percent in 2021, a purchase that came with a right of first refusal on the majority share, as ESPN’s Ramona Shelburne reported when the sale agreement emerged.
That agreement with the Buss Family Trust was announced in June 2025, and the NBA Board of Governors unanimously approved the sale on Oct. 30, 2025, with the transaction closing at a $10 billion valuation — the largest franchise sale in sports history, per the league’s announcement.
The Buss family retained a minority stake of more than 15 percent, and Jeanie Buss remains the team’s governor for at least five years, continuing to oversee day-to-day operations. NBA commissioner Adam Silver said at the time he had no doubt Walter would be a “committed steward of the team.”
That structure is worth restating in this context: Walter is the majority owner, but the franchise’s governor — its official voice in league matters and the executive overseeing its operations — remains Buss.
What this means for the Lakers
In the near term, on the basketball side, nothing changes. The front office spent Monday agreeing to terms with Matisse Thybulle, and there is no reporting that connects the investigation to the team’s payroll, operations or offseason plans.
The Lakers organization is not a party to anything described in the Bloomberg report. The longer-term questions are the ones worth watching honestly.
Walter’s willingness to spend has been central to the fan base’s optimism since the sale — his Dodgers have run one of the largest payrolls in baseball for years — and any development that touches the finances of his broader empire will invite fair questions about whether that posture holds.
There is no evidence in Monday’s reporting that it will not; the insurers themselves stated their financial position is unchanged. The NBA also has its own ownership standards and vetting processes, and the league has not commented on the report as of this writing.
What comes next, if anything, will arrive through the same channels this story did: regulatory filings, follow-up reporting from Bloomberg and The Athletic and any statement the league or the team chooses to make.
Until then, the responsible summary is the simple one — the owner’s companies are under federal investigation, the companies are cooperating, no one has been charged with anything and the Lakers themselves are not part of the story except by association with the man whose name is on the ownership papers.
16 guaranteed contracts, a new head of basketball operations era and now a federal investigation orbiting the owner’s business empire: The Lakers’ first year under Walter was never going to be quiet, but Monday was a reminder that the noise will not always come from the basketball side.
