12 states sue to block Paramount acquisition of Warner Bros. Discovery

A coalition of 12 state attorneys general filed an antitrust lawsuit on Monday, July 13, 2026, seeking to block the $111 billion acquisition of Warner Bros. Discovery by Paramount. The legal action, filed in the U.S. District Court for the Northern District of California, arrives one month after the Department of Justice granted federal approval for the merger following an eight-month review.

The lawsuit is led by California Attorney General Rob Bonta and includes the attorneys general of Arizona, Colorado, Connecticut, Massachusetts, Minnesota, Nevada, New Jersey, New Mexico, New York, Oregon, and Washington. The states allege that the consolidation violates Section 7 of the Clayton Act, arguing the transaction would result in higher prices, reduced quality, and a decrease in content variety for consumers across film, television, and cable distribution.

Legal claims regarding market competition

The plaintiffs contend that the combined entity would control 27 percent of the market for wide-release theatrical film distribution. Furthermore, they assert that the merger would grant the company control over three-tenths of films categorized as "anticipated top-grossing theatrical film distribution." In the sector of licensing basic cable channels to satellite and cable providers, the combined entity would also command a 27 percent market share, as Warner Bros. Discovery is currently the second-largest player in the space and Paramount is the third-largest.

California Attorney General Rob Bonta stated, "The unlawful merger of these two entertainment behemoths would lead to higher prices, lower quality and less content for film and television, harming movie theaters, basic cable distributors and ultimately, audiences on every sofa and movie theater seat in the US." Bonta further added, "With this lawsuit, California and our sister states are fighting for free and fair markets, not rigged markets. America has no kings in government or our economy."

Financial stakes and corporate pressure

The acquisition, spearheaded by Paramount CEO David Ellison and backed by his father, Oracle co-founder Larry Ellison, carries significant financial penalties for delays. Under the terms of the deal, Paramount is obligated to pay Warner shareholders a "ticking consideration" of approximately $650 million for every 90-day interval the closing is delayed, beginning October 1. Should the transaction fail to conclude by June 4, 2027, Paramount faces a $7 billion payment to Warner.

Amid the litigation, reports indicate that advisers have pressured David Ellison to consider relocating Paramount’s corporate headquarters and reallocating planned expenditures out of California. While no formal decision has been reached, the move is viewed by some as potential brinkmanship. Paramount has previously maintained that the deal will enhance competition and benefit consumers, with David Ellison committing to an annual release slate of at least 30 films.

Regulatory and political context

The lawsuit highlights a divide between state authorities and federal regulators. The Department of Justice closed its investigation into the merger in June, concluding that the transaction is not likely to harm competition or American consumers. Conversely, the states are seeking an injunction to prevent the closing of the deal. If Paramount does not voluntarily agree to delay the transaction, the attorneys general plan to pursue a temporary restraining order.

The merger also faces international scrutiny. The United Kingdom’s Competition and Markets Authority opened an investigation in June, and the European Union is currently reviewing the deal, with a provisional decision deadline set for July 22. Paramount has pledged certain concessions to the European Union to earn approval.

Paramount’s acquisition strategy involves financing through debt and significant non-voting investment stakes from sovereign wealth funds based in Saudi Arabia, Qatar, and the United Arab Emirates. The potential merger of news operations, specifically CNN and CBS News, has been a point of public discussion. President Trump has publicly urged the sale of CNN to new owners and has expressed support for the Ellison family's bid.
