Forty attorneys general joined the U.S. Department of Justice in a lawsuit against Live Nation Entertainment, Inc. and its subsidiary, Ticketmaster L.L.C.  The lawsuit alleges that Live Nation has undertaken anticompetitive conduct in various markets across the live concert ecosystem to maintain its monopoly positions in the markets for primary ticketing services for major concert venues, concert promotion services, and use of large amphitheaters in violation of federal and state laws.

In March 2025, the Court denied the defendants’ motion to dismiss.
