Colorado Attorney General Phil Weiser and 11 other states filed a federal antitrust lawsuit Monday to block Paramount Global’s planned merger with Warner Bros. Discovery [1], [2].
The legal challenge represents a significant effort by state governments to prevent further consolidation in the media landscape. Officials said the merger would stifle competition and reduce the diversity of content available to consumers.
The coalition of 12 states filed the action in federal court on July 13, 2026 [4], [5]. The lawsuit targets a deal with a reported value between $110 billion [1] and $111 billion [3]. State officials said the merger would further concentrate the entertainment market, harm movie theaters, and damage the broader entertainment industry in the U.S. [1], [3].
"The deal would harm movie theaters and damage America's entertainment industry," Rob Bonta said [1].
Phil Weiser said, "Colorado will not stand by while a merger threatens competition in the entertainment market" [2].
The lawsuit creates a direct conflict with the federal government's current stance on the deal. On July 12, the U.S. Department of Justice Antitrust Division said that it had determined the merger does not substantially lessen competition [3].
Despite the federal government's approval, the 12 states maintain that the scale of the combined entity would create an imbalance of power. The merger would bring together two of the largest content libraries in the world, potentially limiting the leverage of independent cinema owners and creators in negotiating distribution terms [1], [3].
“"The deal would harm movie theaters and damage America's entertainment industry,"”
This legal action signals a growing trend of state attorneys general challenging massive corporate mergers even when the U.S. Department of Justice declines to intervene. By focusing on the specific impact on movie theaters and market concentration, the states are attempting to use antitrust law to protect the traditional cinema ecosystem from the dominance of a few integrated streaming and production giants.
