The Department of Justice is preparing to file an antitrust lawsuit against Ticketmaster parent company Live Nation, according to a report from The Wall Street Journal. The lawsuit could reportedly come as early as next month and will target the company’s alleged monopoly in the live ticketing industry.

“Ticketmaster has more competition today than it has ever had, and the deal terms with venues show it has nothing close to monopoly power,” a Ticketmaster spokesperson told the Journal. In 2019, the Justice Department blocked Live Nation from coercing venues into using Ticketmaster and also extended its 2010 consent decree to ensure the companies comply. Ticketmaster didn’t immediately respond to The Verge’s request for comment.
