Report: FBI seized Lakers owner Mark Walter’s phone, laptop in federal probe

The federal investigation involving Lakers majority owner Mark Walter has reportedly taken another significant turn.

According to Bloomberg, FBI agents seized Walter’s mobile phone and laptop while executing a court-authorized search warrant aboard his private plane at Chicago Midway International Airport on Sept. 18, 2025.

Bloomberg reported the search was part of a broader federal investigation into the financial dealings of Walter’s business empire, including Guggenheim Partners and two insurance companies he controls through TWG Global.

The FBI confirmed to Bloomberg that agents carried out the search warrant but declined to comment further. Bloomberg noted it remains unclear what investigators were seeking from the devices or whether they are still in government possession.

No criminal charges have been filed against Walter, and investigations of this nature can conclude without charges being brought.

TWG Global issued a statement to Bloomberg saying Walter and the company “have always acted in good faith” and are cooperating with authorities while expressing confidence the matter will ultimately be resolved favorably.

Bloomberg previously reported that federal prosecutors have been examining whether certain private credit investments tied to Walter’s insurance companies and Guggenheim Partners were properly disclosed. The latest report added that investigators have also examined a 2025 investment agreement between TWG Global and Mubadala Capital, though it remains unclear whether that aspect of the inquiry is still active.

Walter became the Lakers’ majority owner last year, with Jeanie Buss remaining the franchise’s governor and continuing to oversee day-to-day basketball operations.

He also owns the Dodgers and Sparks and holds ownership interests in Chelsea FC and several other sports organizations.
