A coalition of 12 U.S. states led by California is suing to block Paramount Skydance’s proposed $110 billion acquisition of Warner Bros. Discovery, setting up a court challenge to federal antitrust clearance. The lawsuit, filed in federal court in the Northern District of California, argues the deal would reduce competition in key areas of film distribution and cable channels, potentially leading to higher prices, less content, and fewer choices for consumers. The states also allege the merged company would gain excessive market power, including in wide-release theatrical film distribution and basic cable channel licensing.

Paramount and its supporters dispute the claims and say the litigation is “fundamentally flawed,” arguing the merger would strengthen competition against major streaming and technology companies such as Netflix, Amazon, and Apple. Paramount also points to prior approvals or clearance in other jurisdictions and says it plans to release at least 30 theatrical films annually with minimum theatrical windows.

The U.S. Department of Justice previously declined to challenge the deal, but the states’ action moves the question to federal court. Sources also note concerns from industry participants, including actors, writers, and theater owners, about potential impacts on jobs and movie output, while Paramount says cost cuts and expanded releases would increase production rather than reduce it.
