A coalition of 12 states has filed an antitrust lawsuit to stop the Paramount Global-Warner Bros. Discovery deal. Warner Bros. and Paramount’s proposed $111 billion merger was always going to draw scrutiny, given the size of the companies involved and the pressure such a deal would put on studios, theaters, and streaming competition, and it did just that.

On paper, the combination would create a powerhouse with major reach across film, cable, and digital entertainment. But that scale is exactly what critics say makes the transaction risky.

Now the merger has run into a serious legal roadblock.

A coalition of 12 states has filed an antitrust lawsuit to stop the deal, arguing that the merger would reduce competition in several important markets. The states, led by California Attorney General Rob Bonta, say the combined company would become too dominant in wide-release theatrical distribution, blockbuster film distribution, and basic cable licensing.

Their central claim is that fewer competitors would mean higher prices, less variety, and fewer opportunities for independent voices in the entertainment industry. The lawsuit also lands despite the fact that the U.S. Department of Justice approved the merger last month, making the states’ challenge a direct defiance of the federal position. State officials insist the deal would not simply reshape Hollywood, but could also harm local movie theaters, cable providers, and audiences who rely on a competitive marketplace.

Bonta said the merger would create “higher prices, lower quality, and less content,” while also warning that no company should be above the law. The case now adds real uncertainty to a deal already facing political and industry resistance. With the states expected to seek an injunction, the merger has hit a major hurdle.

Paramount, however, is signaling that it has no intention of backing down from the fight.

Paramount has pushed back hard against the lawsuit aimed at stopping its Warner Bros. takeover, calling the challenge misguided and economically backward. The company argues that the deal would strengthen, not weaken, competition by creating a better-funded studio that can spend more on films, prestige TV, and creative talent.

In its statement, Paramount said the lawsuit was “fundamentally flawed” and claimed it was effectively protecting Netflix and other large tech-backed streamers from tougher competition. The company says the merger would give it more scale to challenge the biggest players in entertainment while still keeping a healthy flow of movie releases and third-party licensing. Paramount has also promised at least 30 films a year and says it would maintain a 45-day theatrical window.

Earlier, Paramount had even warned that it might leave California if regulators blocked or severely challenged the takeover, framing the legal fight as a threat to business investment in the state. That warning now hangs over the dispute as California and 11 other states argue the merger would concentrate too much power in one company.
