Liberty Media, owner of Formula 1, is under investigation by the U.S. Department of Justice (DOJ) following their rejection of Andretti Global's bid to join the F1 grid. The DOJ probe, initiated after a bipartisan group of U.S. senators and congressmen raised antitrust concerns, questions whether F1's denial was aimed at protecting existing teams from competition. Andretti Global, partnered with General Motors' Cadillac, had its application approved by the FIA but was ultimately rejected by F1, citing doubts about competitiveness and commercial value. Liberty Media's CEO Greg Maffei expressed confidence that their decision complied with U.S. antitrust laws and affirmed the company's willingness to cooperate fully with the investigation. The outcome of this investigation could potentially mandate Andretti's entry into F1, marking a significant development in the sport's expansion and governance dynamics.
