A group of 12 states, led by California Attorney General Rob Bonta, has filed a lawsuit to prevent Paramount's $110 billion acquisition of Warner Bros. Discovery. This action comes after the U.S. Justice Department closed its investigation into the deal without imposing conditions in June, a decision that drew criticism from some, including Senator Elizabeth Warren, who called it a "reaks of corruption" due to Paramount's ties to the Trump administration.

The states involved in the lawsuit are Arizona, California, Colorado, Connecticut, Massachusetts, Minnesota, Nevada, New Jersey, New Mexico, New York, Oregon, and Washington. All of these states have Democratic attorneys general. The lawsuit, filed in the Northern District of California, argues that the merger would stifle competition, increase prices for consumers, reduce the quality of content, and lead to fewer films and shows being produced annually. Paramount has stated it will vigorously fight the lawsuit, asserting that the states' claims are inaccurate and that the merger would actually enhance competition.

The lawsuit specifically targets three areas of competition: wide-release film distribution, distribution of anticipated blockbuster films, and cable channel licensing. Projections indicate that the combined entity would control approximately 27% of the market for widely released films and over 30% of blockbuster films. Additionally, the merger would create a media giant holding over 27% of the cable and satellite TV market by viewership, combining the second and third-largest players in that sector. The coalition has requested that Paramount and Warner Bros. refrain from closing the merger until the judicial process concludes, threatening to file a temporary restraining order if they do not comply.

The timing of the lawsuit presents a significant challenge for Paramount, which aimed to complete the merger by the end of September. The merger agreement includes a "ticking fee," meaning Paramount would incur a cost of $650 million per quarter if the deal is not finalized by September 30. Analysts have suggested that state prosecutors might face a more difficult task in proving antitrust harm compared to federal regulators, yet California Attorney General Bonta expressed confidence at a press conference. The outcome of this state-led legal battle remains uncertain, but it highlights the growing trend of state-level officials intervening in major corporate mergers previously cleared by federal agencies.

The proposed merger would unite Paramount's assets, including Paramount Studios, CBS News, and networks like Comedy Central and Nickelodeon, with Warner Bros. Discovery's holdings, such as the "Harry Potter" franchise, CNN, HBO Max, TBS, and TNT. David Ellison, son of Oracle Corp. co-founder Larry Ellison, would reportedly lead the combined entity, which would oversee both CBS and CNN, as well as the streaming services Paramount+ and HBO Max. Critics, including more than 5,000 industry professionals and celebrities, have voiced concerns that the merger would lead to fewer opportunities for creators, job losses, higher costs, and reduced audience choice.
