Twelve States Challenge Paramount and Warner Bros. Discovery Merger

The legal challenge invokes the Clayton Act, alleging the deal would grant the combined entity an outsized grip on the media landscape. Specifically, the states contend the merger would consolidate 27% of the U.S. film distribution market, 30% of blockbuster distribution, and 27% of the basic cable channel market. Bonta frames the move as a defense of fair markets, warning that such extreme consolidation limits the diversity of stories reaching audiences and inevitably drives up consumer prices.

This litigation arrives despite the U.S. Department of Justice previously clearing the transaction, finding no significant harm to competition. While Paramount CEO David Ellison had targeted a September closing date for the deal—which unites platforms like Paramount+ and HBO Max with networks including CBS, MTV, and CNN—the state-level intervention introduces a major hurdle. Joining California in the suit are Arizona, Colorado, Connecticut, Massachusetts, Minnesota, Nevada, New Jersey, New Mexico, New York, Oregon, and Washington.
