WASHINGTON, D.C. - The US Department of Justice (DoJ) filed a major antitrust lawsuit on Thursday seeking to break up an alleged monopoly in the live music industry between concert promoter Live Nation Entertainment and its subsidiary, bookings website Ticketmaster.

The lawsuit, filed in a federal court in New York, claims that Live Nation has abused its dominant market position to raise ticket fees, squeeze out competitors and limit choices for fans, venues and artists.

"Live Nation relies on unlawful, anticompetitive conduct to exercise its monopolistic control over the live events industry in the United States at the cost of fans, artists, smaller promoters and venue operators," said US Attorney General Merrick Garland in a statement.

"It is time to break up Live Nation."

Ticketmaster's pricing practices for concerts and other events, with high fees and lack of alternatives, have long been a political issue in the United States, with little done historically to open up the market to more competition.

The latest controversy over Ticketmaster's dominance came when tickets for Taylor Swift's Eras tour went on pre-sale in 2022.

Widespread outages and exorbitant fees caused an uproar, with lawmakers in Washington holding hearings to question Live Nation executives over the debacle.

The move against Live Nation also comes as the Biden administration, according to polls, is seen by voters as failing to do enough to curb inflation.

High prices have become a key issue in battleground states ahead of the 2024 election that pits Biden against former president Donald Trump.

"While we do not comment on specific enforcement matters, President Biden strongly supports fair and robust enforcement of the antitrust laws," White House Press Secretary Karine Jean-Pierre said.

"As the President has said, the American people are tired of being played for suckers."

Live Nation, which merged with Ticketmaster in 2010, has grown into a $22 billion global giant that produces more than 30,000 concerts annually for nearly 500 touring artists across its network of over 265 North American venues.

In a statement, Live Nation said the lawsuit "won't solve the issues fans care about relating to ticket prices, service fees and access to in-demand shows."

"Calling Ticketmaster a monopoly may be a PR win for the DoJ in the short term, but it will lose in court because it ignores the basic economics of live entertainment," it added.
