A coalition of 12 state attorneys general filed an antitrust lawsuit on Monday to block Paramount Global’s proposed acquisition of Warner Bros. Discovery [1].

The legal challenge threatens to derail one of the largest media consolidations in history. If successful, the suit could prevent the formation of a massive entertainment entity, altering the competitive landscape of streaming and traditional broadcast media.

Jeffrey Kessler, lead trial counsel for Paramount-Skydance and partner at Winston Taylor, defended the deal during an appearance on CNBC’s “Squawk on the Street” this Tuesday. He said the merger is pro-competitive [1].

The acquisition is valued at $111 billion [3]. While the U.S. Department of Justice has already provided approval for the deal, the state-led coalition argues that the merger would reduce competition within the media, and entertainment market [1, 2].

Kessler said that the consolidation would increase competition and provide greater benefits to consumers [1, 2]. The lawsuit was filed in federal court earlier this week, creating a legal hurdle as the companies move toward their deadline [2].

Despite the ongoing litigation, Paramount continues to pursue the transaction. The company has set a target closing date for the merger by the end of September 2026 [4].

The legal battle centers on whether the combined entity would hold too much power over content distribution and pricing. The state attorneys general seek to prevent a market imbalance that they believe would harm the industry's overall health [2].

This merger is pro-competitive.

The lawsuit represents a strategic effort by state-level regulators to exert influence over media consolidation, even after federal approval from the Department of Justice. By challenging the $111 billion deal in federal court, these states are testing the legal boundaries of market competition in the streaming era, where scale is often viewed as a necessity for survival against tech giants.
