US states may sue to block Paramount’s $110B acquisition of Warner Bros. Discovery

The biggest media deal in years just hit a wall, and it’s not the one anyone expected. Several US states, led by California and New York, are preparing to file an antitrust lawsuit to block Paramount Skydance’s roughly $110.9 billion acquisition of Warner Bros. Discovery, even after the Department of Justice gave the merger a clean bill of health.

The deal so far

Paramount Skydance announced the acquisition of Warner Bros. Discovery on February 27, 2026. The combined entity would merge some of the most recognizable studios and streaming platforms in entertainment under a single corporate umbrella.

The DOJ’s Antitrust Division completed an eight-month review and approved the deal without conditions around June 12, 2026.

WBD shareholders overwhelmingly approved the transaction on April 23, 2026.

California, New York, and several other states began preparing an antitrust challenge in early June 2026, with a filing expected imminently. Their concern centers on potential reductions in market competition across the media and entertainment sectors.

Oregon has already initiated its own investigation, which has pushed the deal’s potential closing date past July 22, 2026.

Federal versus state: the antitrust tug of war

State attorneys general have independent authority to bring competition cases. This kind of federal-state divergence isn’t unprecedented, but it’s unusual for a deal of this magnitude.

What this means for investors

Paramount has already built a financial cushion into the deal structure for exactly this kind of scenario. The company has committed to a “ticking fee” of $0.25 per share if the transaction experiences delays beyond December 31, 2026.

The deal’s targeted Q3 2026 close looks optimistic at best. Oregon’s probe has already pushed things past July 22, 2026. A multi-state lawsuit would likely extend the timeline well beyond that, potentially testing Paramount’s patience and its wallet via those ticking fees.
