States Plan Antitrust Suit to Block Paramount–Warner Bros. Deal

State attorneys general plan an antitrust suit to block Paramount's $111 billion takeover of Warner Bros. despite federal approval.

Several state attorneys general are preparing to file an antitrust lawsuit challenging Paramount Skydance's acquisition of Warner Bros., with International Business Times reporting, per CNN, that the suit could be filed as soon as next week. The states are moving forward even though the U.S. Justice Department approved the transaction in June, writing that it is "not likely to result in harm to competition or American consumers." California Attorney General Rob Bonta confirmed only that the Paramount acquisition "remains an active investigation," while Oregon Attorney General Dan Rayfield sought enforcement of a subpoena tied to the case, with that hearing rescheduled to Monday.

The legal threat defies the usual pattern in which a DOJ clearance effectively ends antitrust risk for a mega-merger. The deal already cleared its biggest shareholder hurdle: Warner Bros. shareholders approved Paramount's offer in April, selling the company's entire business for $31 a share in a deal valued at roughly $111 billion, according to the Associated Press as cited by International Business Times. The DOJ also expressly rejected critics' labor arguments, finding that demand for creative workers tracks studios' incentives to maintain output. Paramount, for its part, says it is "prepared to address any legitimate antitrust issues" and is "confident this transaction raises no such concerns."

A University of Wisconsin–Madison event study of the bidding war helps explain why regulators and consumers remain wary of streaming consolidation. It found Netflix's proposed $27.75-per-share bid for Warner Bros. Discovery, announced December 5, 2025 at an $82.7 billion enterprise value, triggered statistically significant negative abnormal returns for Netflix of up to -22.62%, while Paramount Skydance's $31 cash bid ultimately won in February 2026. The study argues the resulting consolidation of two legacy studios' libraries risks reducing the diversity of films and series available to consumers — a tension between market efficiency and cultural output it places beyond the paper's scope.

Opponents argue the merger would concentrate news and entertainment in ways that harm consumers — CNN, the outlet Paramount would acquire, is among the properties in play. Creative-industry voices have amplified the alarm: Jane Fonda told TheWrap at the DVF Awards in Venice that "the merger would be terrible for consumers. Prices would go up. Thousands and thousands of people would lose their jobs," and that fewer studios mean less bargaining power and weaker unions. The University of Wisconsin–Madison study adds a cautionary precedent: the 2000 AOL-Time Warner merger produced a $98.7 billion loss in a single year, widely regarded as one of the most catastrophic in corporate history.

Expect the courtroom fight to begin within days if CNN's reporting is right, with Oregon's subpoena-enforcement hearing already set for Monday and California keeping its investigation formally open. Paramount says it will continue engaging constructively with state attorneys general, but a state-level suit could freeze closing timelines the way earlier halts already have. The dispute also lands amid a broader wave of media consolidation, with Paramount's own pick of regulatory terrain shaped by ties the Wisconsin study notes between the Ellison family and the Trump administration.
