Cadillac F1 controlling majority stakeholder Mark Walter is now facing a class-action lawsuit, which was filed against his business empire, TWG Global, in the United States. The aforementioned company owns the newest team on the F1 grid through its motorsport wing, TWG Motorsport.
TWG, led by Walter, acquired Andretti following their unsuccessful bid to enter F1, and then partnered up with General Motors through its motorsport arm to launch the Cadillac F1 team, which made its debut in the sport in 2026. The company is hence the primary financial backer of the project.
The complaint against Walter alleges that the businessman’s companies concealed federal investigations and used billions of dollars from insurance policyholders to finance businesses linked to his wider corporate network. This is only the latest development in an ongoing investigation into Walter’s insurance businesses and their financial dealings.
Delaware Life and Clear Spring Life, both subsidiaries of TWG, have faced scrutiny over investments that were initially classified as being made with independent entities but were later identified as related-party investments. Delaware Life subsequently restated its financial statements, with affiliated investments accounting for around 42% of its assets at the end of 2025.
The class-action lawsuit was filed in the U.S. District Court for the Southern District of Florida by Ira Rosner, represented by law firm Robbins Geller Rudman & Dowd.
Walter’s portfolio has included investments in multiple sporting entities, including not only Cadillac F1, but also MLB side Los Angeles Dodgers, NBA team Los Angeles Lakers and Premier League club Chelsea. But more recently, TWG has sold its stakes in the LA Lakers and Chelsea.
This, on top of the ongoing investigation and lawsuit, naturally brings into question the company’s future relating to Cadillac F1. But TWG had recently stated firmly that it has no intentions of selling any of its stakes in either the F1 outfit or the LA Dodgers.
Cadillac F1 boss tells Sergio Perez to “control the expectations”
On the sporting side of things, Cadillac F1 team principal Marcin Budkowski has responded to driver Sergio Perez recently claiming that the American team has faced a few “disappointments” with development in 2026. The new team boss, who replaced Graeme Lowdon in August, told the Mexican driver to “control” his expectations for 2026.
“I think you have to put that in perspective with the drivers’ expectations and the reality of the seasonality of F1,” Budkowski told the media at the Spanish GP.
“Before I even started, after my appointment was announced, I had a quick chat with both drivers. And Sergio asked me, ‘What are you going to do for Zandvoort?’, which is a week after I started. And I said, ‘Well, Checo, I think I need to control the expectations a little bit.'”
Budkowski has also revealed that Cadillac has shifted focus to 2027, which is naturally affecting the resources the team can put into bringing upgrades to the 2026 car. He also added that a significant amount of resources in 2026 have gone into fixing reliability issues rather than focusing on performance as well.
