A coalition of 12 state attorneys general led by California Attorney General Rob Bonta filed an antitrust lawsuit on Monday seeking to block Paramount Skydance’s acquisition of Warner Bros. Discovery in a deal valued at about $110–$111 billion. The states argue that the merger, which would combine major movie studio and television assets, would violate antitrust law by reducing competition across areas including wide-release filmmaking, basic cable distribution, and related markets.

The lawsuit is filed in federal court in Sacramento. The filing comes despite approval from the Department of Justice, which cleared the transaction last month. The states contend that DOJ’s clearance does not address the competitive harms they allege, including potential damage to movie theaters and broader effects they say could lead to higher prices for consumers.

Multiple outlets report the states seek to prevent the merger from closing or to stop it through other court remedies. The legal action sets up a challenge to a Hollywood “mega-merger” that was announced after a bidding process involving Paramount Skydance and Netflix.
