Liberty Media, the owner of Formula 1, is under investigation by the U.S. Department of Justice regarding its decision to reject Andretti Global's bid to join the racing series as its 11th team. This decision has raised concerns about potential violations of U.S. antitrust laws, influenced by doubts about Andretti's competitiveness and existing teams' reluctance to share prize money. Despite receiving initial support from the FIA, Andretti's application was ultimately denied, prompting scrutiny from U.S. senators and calls for accountability. Liberty Media President Greg Maffei has stated that the company will fully cooperate with the investigation and believes their decision was compliant with antitrust laws. Andretti Global remains committed to pursuing entry into Formula 1, having established new operations in Silverstone and hired notable industry figures. The situation continues to evolve as both sides prepare for a potential legal and competitive battle over the future of the racing series.
