Antitrust enforcement in live music refers to regulatory efforts to prevent monopolistic practices and promote competition in the concert industry. The most prominent case is the 2024 DOJ lawsuit against Live Nation-Ticketmaster¹, alleging the company maintains illegal monopolies in concert promotion and ticketing. Live Nation controls over 80% of major venue ticketing² and uses exclusionary practices to stifle competition. This enforcement theme encompasses broader efforts to break up concentrated market power that drives up ticket prices and limits consumer choice in live entertainment.
