A coalition of 12 state attorneys general, led by California’s Rob Bonta, has filed a lawsuit to block the proposed $110 billion acquisition of Warner Bros. Discovery by Paramount Skydance. The lawsuit, filed Monday in the U.S. District Court for the Northern District of California, raises antitrust concerns, warning that the merger would significantly limit competition in the entertainment industry and harm consumers by leading to higher prices and reduced content quality. The states involved include Arizona, Colorado, Connecticut, Massachusetts, Minnesota, Nevada, New Jersey, New Mexico, New York, Oregon, and Washington.

The merger would unite two major Hollywood studios and their streaming platforms—Paramount+ and HBO Max—and create the largest collection of U.S. TV networks, combining CBS, MTV, BET, CNN, and TNT under one umbrella. Paramount CEO David Ellison has indicated the streaming services would consolidate following the deal, which has faced pushback not only from state officials but also industry groups like the Writers Guild of America and Cinema United, both of which voiced concerns over job losses and fewer film releases. Despite this opposition, the U.S. Department of Justice and multiple global regulators have already approved the transaction.

Paramount has criticized the lawsuit as a misunderstanding of the competitive realities of today's media market, emphasizing the potential benefits of combining forces against industry giants like Netflix. The company insists that the merger will foster more creativity, competition, and consumer choice, warning that delays could harm entertainment workers who have already faced significant disruptions. If the deal does not close by September 30, Paramount is contractually obligated to pay Warner Bros. Discovery shareholders a ticking fee amounting to roughly $650 million quarterly, adding pressure to finalize the merger promptly.

The bid for Warner Bros. Discovery began in September 2025 when Paramount’s Skydance initiated a hostile takeover after a failed deal with Netflix. After months of negotiations and regulatory scrutiny—including ongoing review by the European Union—the merger aims to finalize by September 2026. The current lawsuit adds a new legal hurdle that could delay or block closing the transaction, which shareholders had previously approved. As legal and regulatory challenges mount, the outcome remains uncertain, with significant implications for the future structure of the media and entertainment landscape.
