12 States Sue to Block Paramount’s $110 Billion Warner Bros. Discovery Takeover

A New Legal Front Opens Against the Paramount-Warner Bros. Discovery Merger

For months, the proposed marriage of Paramount Skydance and Warner Bros. Discovery looked like it was headed toward a relatively smooth close. The Justice Department reviewed the $110 billion transaction and, in June 2026, cleared it without imposing a single condition. European regulators signaled they were open to approval as well, provided Paramount agreed to sell off some children’s television assets. Then, on July 13, 2026, twelve state attorneys general filed a federal antitrust lawsuit in California seeking to stop the deal entirely.

The Paramount Warner Bros. Discovery lawsuit is now the most serious obstacle standing between Paramount Skydance and full ownership of one of Hollywood’s oldest studios, its cable news operation, and its streaming platform. It also marks a broader shift in how antitrust enforcement is happening in the United States: increasingly, it is state attorneys general, not just federal regulators, deciding which mergers get challenged in court.

Who Is Suing, and Why

The coalition is led by California Attorney General Rob Bonta and includes Arizona, Colorado, Connecticut, Massachusetts, Minnesota, Nevada, New Jersey, New Mexico, New York, Oregon, and Washington. Every state in the group is represented by a Democratic attorney general, and the lawsuit was filed in the U.S. District Court covering California, where Paramount is headquartered.

At a press conference announcing the filing, Bonta framed the case as a defense of basic market competition. His argument, in short: antitrust law exists precisely so that no single company can grow so large it no longer has to compete on price, quality, or innovation. The states contend that combining Paramount and Warner Bros. Discovery would do exactly that inside the market for licensing cable television channels and distributing feature films to theaters.

The Core Antitrust Argument

According to the lawsuit, Warner Bros. Discovery currently ranks as the second-largest company in the cable channel licensing market, while Paramount ranks third. Combined, the states argue, the merged company would control approximately 27% of that market enough concentration, they say, to let the new company push up prices for cable and streaming bundles while offering fewer independent programming choices.

The complaint also raises concerns specific to the entertainment workforce. State attorneys general argue that a combined Paramount-Warner Bros. Discovery would become one of the largest single buyers of scripted film and television content in the country, giving it outsized leverage over how much writers, directors, and other creative professionals get paid and how many projects get greenlit in the first place.

A Broader Pattern: State AGs Filling the Antitrust Gap

This is not an isolated move. State attorneys general across the country have become markedly more willing to pursue merger challenges even after federal agencies decline to act. A coalition of states continued pressing an antitrust case against Live Nation and Ticketmaster after the DOJ reached its own settlement with the company and a jury ultimately ruled in the states’ favor. Separately, states sued to block Nexstar’s acquisition of Tegna on antitrust grounds even though both the DOJ and the FCC had approved that broadcast merger.

Taken together, these cases suggest state attorneys general increasingly view themselves as a backstop when they believe federal regulators have been too permissive. For companies pursuing large mergers, that means DOJ or FTC clearance is no longer the final word state-level antitrust risk has become a real, and sometimes decisive, variable in deal planning.

What Paramount and Warner Bros. Discovery Are Saying

Paramount Skydance has pushed back on the states’ claims, arguing that the combined company would be better positioned to compete against streaming giants like Netflix, Amazon, and Disney rather than harm competition. The company has framed the merger as a defensive consolidation move in an entertainment landscape where traditional media companies are losing ground to tech-backed streaming platforms with far larger budgets and global reach. Warner Bros. Discovery has largely echoed that position, emphasizing the cost synergies and content investment the merger is expected to unlock.

Neither company has agreed to pause the transaction voluntarily. The state coalition has said it asked both companies to hold off on closing until the litigation concludes and indicated it intends to seek a temporary restraining order to force that outcome if necessary.

What Happens Next

The case now moves into the standard rhythm of federal antitrust litigation: motions, discovery, and eventually a hearing on whether a preliminary injunction or restraining order is warranted. Courts weighing these requests typically look at whether the states are likely to succeed on the merits and whether allowing the deal to close before a full trial would cause irreversible competitive harm.

A decision on the states’ request for a restraining order could come within weeks, but the underlying antitrust case is likely to take considerably longer to resolve. In the meantime, the Writers Guild lawsuit adds another layer of legal exposure, and European regulators’ ongoing review reportedly contingent on asset sales remains an open variable. For now, the merger that once looked cleared for takeoff is grounded in a legal holding pattern, with its outcome resting in the hands of a California federal judge.

Frequently Asked Questions

What is the Paramount Warner Bros. Discovery lawsuit about?
The Paramount lawsuit is an antitrust case filed on July 13, 2026, by 12 state attorneys general in federal court in California. The states argue that Paramount Skydance’s $110 billion acquisition of Warner Bros. Discovery would combine the second- and third-largest players in cable channel licensing and film distribution, giving the merged company roughly 27% of that market and reducing competition for consumers, advertisers, and entertainment workers.

Which states are suing to block the Paramount merger?
The coalition is led by California and includes Arizona, Colorado, Connecticut, Massachusetts, Minnesota, Nevada, New Jersey, New Mexico, New York, Oregon, and Washington. All 12 states are represented by Democratic attorneys general, with California Attorney General Rob Bonta serving as the lead plaintiff.

Did the Department of Justice already approve the Paramount-Warner Bros. Discovery deal?
Yes. The DOJ’s Antitrust Division closed its investigation and cleared the transaction without conditions in mid-June 2026, concluding the deal was not likely to harm competition or consumers. The state lawsuit is a separate legal track and does not depend on federal approval state attorneys general can sue under both state and federal antitrust law even after DOJ clearance.

Is this the only lawsuit challenging the merger?
No. A day after the states filed suit, the Writers Guild of America filed its own separate lawsuit, arguing the combined company would become the largest buyer of original film and television programming in the country and would suppress pay and job opportunities for writers.

What are the states asking the court to do?
The coalition is seeking a court order blocking the merger outright, and has said it will pursue a temporary restraining order to stop Paramount and Warner Bros. Discovery from closing the transaction while the case is litigated.

How does this compare to other recent state antitrust actions?
State attorneys general have grown more active in challenging deals that federal regulators clear or decline to block. A bipartisan coalition of states pressed on with an antitrust case against Live Nation and Ticketmaster after the DOJ reached a separate settlement, and a jury ultimately sided with the states. States also sued to block the Nexstar-Tegna broadcast merger even after the DOJ and FCC signed off on it.
