A coalition of twelve U.S. states, the Writers Guild of America, and a group of Paramount shareholders have filed a series of lawsuits aimed at stopping Paramount Skydance’s $111 billion acquisition of Warner Bros. Discovery. The suits allege that the merger would violate federal antitrust law, hurt consumers, and damage the film and television industries.

The state attorneys general lawsuit, filed last week, lists California and New York among the 12 states. According to the complaint, the merger would shrink competition in the entertainment market, leading to higher prices and fewer choices for customers. The suit also argues that the consolidation would undermine independent studios and limit opportunities for new content.

The Writers Guild of America joined the legal challenge with its own suit. The guild contends that the combined company would heighten concentration in the writing market, reduce the quantity and variety of theatrical films and television series, and apply downward pressure on writers’ compensation. The guild’s complaint states that the merger would make it easier for the remaining firms to coordinate and suppress competition.

In a separate action, Paramount shareholders filed a lawsuit in Delaware Chancery Court. The investors allege that CEO David Ellison and his father Larry made illegal deals with the Trump administration to secure approval of the merger. The complaint cites Ellison’s promise to overhaul CNN if Warner Bros. Discovery is acquired, a $16 million settlement to President Trump in 2025, and a $20 million payment for free, pro‑conservative advertising. The investors claim these actions harm the reputation of Paramount’s news outlets and create latent liabilities.

A fifth lawsuit, originally brought by five Paramount+ subscribers, argued that the merger could lead to price hikes and reduced viewing options. That suit was merged into the federal antitrust case filed by the state attorneys general.

Paramount has responded to the litigation by calling the antitrust challenge “one of the weakest merger challenges in modern antitrust history.” The company’s lawyers point to competitors such as Disney and Universal as evidence that competition will remain vigorous. They also argue that the acquisition will increase, not decrease, theatrical motion‑picture output and will not adversely affect theater pricing.

An 80‑minute hearing took place in Oakland on Friday between Paramount and the state attorneys general. U.S. District Judge Araceli Martínez‑Olguín heard arguments from both sides and said she would issue a ruling on the emergency motion for a temporary restraining order (TRO) by Wednesday, July 22. The state attorneys general seek a 28‑day TRO that would bar Paramount and Warner Bros. Discovery from closing the deal. If Paramount fails to complete the merger by September 30, the parties say the company will be required to pay investors $7 million per day.

Paramount had previously promised not to close the deal until the judge’s decision on the TRO. Depending on the outcome, the company may have to wait longer than the September 30 deadline.

At this stage, the merger remains pending. The federal antitrust case, the state attorneys general lawsuit, the Writers Guild suit, and the investor complaint are all moving through the courts. The outcome of Judge Martínez‑Olguín’s ruling on the TRO will determine whether the merger can proceed or whether it will be halted until the court’s final decision.

The litigation highlights growing concerns about media consolidation, political influence in corporate deals, and the impact of large mergers on competition and consumer choice. The next few weeks will see the court’s decision on the TRO and the continuation of the lawsuits, which could shape the future of the U.S. entertainment industry.
