US Judge Temporarily Halts Paramount-Warner Bros. Merger

A US federal judge has temporarily halted Paramount Skydance’s proposed US$110 billion acquisition of Warner Bros. Discovery, granting a 14-day restraining order sought by a coalition of 12 states while the court evaluates antitrust claims that the merger could reduce competition, raise prices, and limit film and television content.

A US federal judge has temporarily paused Paramount Skydance’s proposed acquisition of Warner Bros. Discovery, marking the most significant legal setback yet for the US$110 billion transaction and increasing uncertainty around one of the largest media deals in recent years.

The temporary restraining order, issued by US District Judge Araceli Martínez-Olguín on Monday, prevents Paramount from completing the merger for at least 14 days while the court considers a request for a preliminary injunction filed by a coalition of 12 states led by California. If granted, the injunction would block the transaction until the underlying antitrust lawsuit is resolved.

“Plaintiff States’ showing at least demonstrates that serious questions going to the merits remain, weighing in favor of preliminary injunctive relief,” says Martínez-Olguín in the court order. The judge adds that Paramount would not be significantly harmed by the temporary delay because both companies would continue operating independently while the litigation proceeds.

Court Order Raises Stakes for Landmark Media Deal

The ruling follows a lawsuit filed on July 13 by California and 11 other states, which argue that combining Paramount and Warner Bros. Discovery would substantially reduce competition across theatrical film distribution, blockbuster releases, and basic cable programming.

State attorneys general contend the merger would create a dominant entertainment company with greater leverage over movie theaters, cable and satellite distributors, and consumers. They also argue that allowing the transaction to close before the legal challenge is resolved could trigger job reductions and the exchange of competitively sensitive information between the companies, actions they say would be difficult to reverse if the merger were ultimately found to violate antitrust law.

Rob Bonta, Attorney General of California, describes the ruling as an important early victory for the states' challenge. “History tells the tale of what happens when a few people have great power over markets that are central to Americans’ lives: fewer opportunities for more people, worse products and services for all people,” says Bonta. “With our lawsuit, we are fighting for a free and fair market and a thriving film and television industry that serves creatives and audiences alike.”

Martínez-Olguín has scheduled a hearing for Aug. 3 to determine whether a preliminary injunction should remain in place while the court evaluates the merits of the states’ claims. The current restraining order could also be extended to 28 days if necessary.

The timing is particularly significant because Paramount faces growing financial pressure to complete the acquisition before Sept. 30. Under the merger agreement, the company would begin paying quarterly compensation to Warner Bros. Discovery shareholders if the transaction remains incomplete beyond that deadline. Those payments have been estimated at more than US$600 million per quarter.

Paramount Defends Competitive Impact

Paramount has rejected the lawsuit, arguing that state regulators are mischaracterizing both the media industry and established antitrust law. The company maintains that today's entertainment market is substantially more competitive than the lawsuit suggests, citing the expansion of streaming platforms and the emergence of new film distributors alongside established studios. Paramount has also argued that the traditional cable television market continues to contract, making historical market concentration metrics less relevant.

In a statement, the company says it will continue defending the transaction and argues that the legal challenge does not reflect the competitive realities of the modern media industry.

The merger has already received clearance from the US Department of Justice, while regulators in several international markets, including Australia and China, have also approved the transaction. However, additional reviews remain underway internationally, including in the European Union, adding further complexity to the closing process.

Antitrust Battle Extends Beyond Regulatory Review

The court order reinforces how state-level antitrust enforcement can reshape major transactions even after federal regulatory approval has been secured. The coalition's lawsuit argues that the combined company would gain excessive influence across theatrical film distribution and cable television programming, potentially reducing negotiating leverage for exhibitors and television distributors while limiting consumer choice.

The states also contend that the merger would diminish competition between two of Hollywood's largest studios at a time when the entertainment industry is already undergoing significant consolidation. The transaction has also attracted opposition from labor organizations and consumer groups. The Writers Guild of America has separately challenged the merger on antitrust grounds, arguing that further consolidation could reduce employment opportunities and weaken bargaining power across the entertainment industry.

Consumer plaintiffs have also raised concerns about combining the companies' streaming businesses, although a separate request to block the merger was previously denied.
