Mark Walter's holding company TWG Global has firmly denied launching a "fire sale" of its assets, stating there had been "no fraud" at its companies. This comes as regulatory pressure mounts across Walter's billionaire financier empire. US prosecutors and the Securities and Exchange Commission have probed TWG and entities linked to Walter this year.

In June, two insurers he controls disclosed receiving subpoenas from the Manhattan district attorney's office and admitted misclassifying over $20 billion in investments. TWG affirmed its commitment to working with the Department of Justice and SEC to resolve the inquiries, insisting no one has been harmed. The group is racing to offload billions in affiliated investments, though several investors rejected deals or demanded steep discounts.

Walter, also CEO of Guggenheim Partners, recently reached a deal to sell his majority stake in the Los Angeles Lakers, valuing the team at $12.5 billion—a 25 percent premium less than a year ago. He also held talks to sell his stake in Chelsea Football Club. TWG clarified the Los Angeles Dodgers and its Cadillac Formula 1 team are not for sale.
