Paramount Skydance’s proposed acquisition of Warner Bros. Discovery has suffered a significant setback after a U.S. federal judge temporarily halted the transaction, marking the first major legal obstacle to a deal that would reshape the global entertainment industry.
U.S. District Judge Araceli Martínez-Olguín on Monday ordered a 14-day pause on the merger after hearing arguments from both sides last week, following a lawsuit filed by a coalition of 12 state attorneys general led by California Attorney General Rob Bonta.
The temporary injunction gives the states time to pursue a longer injunction that could further delay or potentially derail one of the biggest media consolidation efforts in recent years.

The proposed merger would combine two of Hollywood’s most influential studios and create an entertainment giant spanning film production, television networks and streaming services. It would bring together Paramount Pictures and Warner Bros. Pictures, while combining streaming platforms Paramount+ and HBO Max. The combined company would also control an extensive portfolio of television assets, including CBS, MTV, CNN and HBO.
The coalition of attorneys general argues that the transaction would substantially reduce competition across key segments of the entertainment industry. Their lawsuit contends that the merger would harm movie theaters, cable distributors, creative professionals and consumers by concentrating excessive market power in a single company.
According to the complaint, competition would be weakened in at least three major markets: wide-release theatrical film distribution, the distribution of top-grossing theatrical films, and licensing of programming to basic cable television providers.
“This is a critical first win in our case to ensure this megamerger never sees the light of day,” California Attorney General Rob Bonta said in a statement.
“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. With our lawsuit, we’re fighting for a free and fair market and a thriving film and television industry that serves creatives and audiences alike. We have a full tank of gas, the law on our side, and look forward to continuing to make our case.”
The case has added to the growing scrutiny of consolidation in the U.S. media and technology sectors as regulators challenge deals they believe could reduce competition, limit consumer choice and weaken bargaining power for content creators and distributors.
Paramount rejected the allegations, arguing that the merger reflects the realities of today’s highly competitive media landscape, where traditional entertainment companies face intense pressure from streaming leaders such as Netflix, Disney and Amazon.
“We are confident the evidence will demonstrate that the State AGs’ antitrust arguments are without merit as their alleged markets and claims of anticompetitive effects are without any basis in modern market realities,” a Paramount spokesperson said in a statement.
“This merger is lawful, pro-competitive, and will benefit consumers, creators, workers, and the entertainment industry. We will continue to vigorously defend the transaction and will look forward to the hearings on the substance of the State AGs’ action.”
The company says that combining their businesses would create a stronger competitor capable of investing more aggressively in premium content and competing with much larger global streaming platforms.
The legal challenge comes at a crucial time for Paramount. Chief Executive David Ellison said in May that the transaction remained on track to close by September, with the merger viewed as central to the company’s long-term strategy to strengthen its position in the increasingly competitive streaming market.
A prolonged court battle could disrupt that timeline, create uncertainty for investors and employees, and delay integration plans.
The merger has also attracted opposition from filmmakers, actors and other entertainment industry groups, who say that further consolidation would reduce the number of major buyers of creative content, potentially weakening negotiating power for producers, writers and performers while limiting opportunities for independent studios.
If ultimately approved, the combination would create one of the world’s largest entertainment companies, bringing together two of Hollywood’s oldest film studios, expanding content libraries across film and television, and strengthening the combined company’s ability to compete globally in streaming, sports broadcasting and premium television.
For now, however, the future of the transaction remains uncertain as the court considers whether the states have demonstrated sufficient antitrust concerns to justify extending the injunction beyond the initial 14-day period. A longer delay could complicate Paramount’s plans and prolong regulatory uncertainty surrounding one of the media industry’s most consequential proposed mergers.
