Antitrust enforcement remained one of the most important U.S. legal developments in the last 24 to 72 hours, with fresh activity in the government’s ongoing campaign against major technology platforms. Recent filings and hearing activity in several headline matters show enforcers moving beyond liability theories and deeper into the remedies phase—where structural relief, business-practice restrictions, and long-term compliance obligations become concrete risks rather than abstract possibilities.

That shift matters.

A federal judge in the Eastern District of California has blocked Nexstar Media Group’s proposed acquisition of Tegna while antitrust litigation proceeds, handing opponents of the deal an important early win and underscoring how merger challenges can survive even after federal regulators decline to stop a transaction.

Judge Troy Nunley found that the challengers were likely to succeed, a significant conclusion at the preliminary injunction stage.

The Justice Department’s Antitrust Division has proposed a settlement with Agri Stats to resolve allegations that the company facilitated unlawful information-sharing among competing meat processors. The case, pending in the District of Minnesota, centers on claims that Agri Stats collected and distributed detailed price, output, and cost data in ways that allowed poultry, pork, and turkey producers to coordinate behavior rather than compete independently.

According to the government, the proposed settlement is designed to restore competitive conditions in protein markets that affect both upstream producers and downstream purchasers.

Federal antitrust enforcers are stepping into a debate that goes to the heart of how lawyers enter the profession. In comments to the Tennessee Supreme Court, staff at the Federal Trade Commission and the DOJ’s Antitrust Division urged the court to reduce or eliminate its reliance on American Bar Association accreditation as a prerequisite for bar eligibility.

The agencies’ core argument is straightforward: when a single private accreditor effectively controls access to the profession, it can drive up educational costs and restrict competition.

The U.S. Supreme Court has declined to pause a lower-court order holding Apple in contempt in its long-running fight with Epic Games, a procedural move that keeps immediate pressure on Apple while the broader dispute over App Store payment rules continues.

The order stems from the remedy phase of the Epic litigation, where Apple was previously directed to loosen restrictions affecting how app developers communicate alternative payment options to users.

A federal judge in California has put the proposed Nexstar Media Group acquisition of Tegna on hold, preventing the deal from moving forward until antitrust claims are resolved. The ruling by Judge Troy Nunley of the U.S. District Court for the Eastern District of California marks a significant development in a closely watched fight over consolidation in local television and broadcast markets.

The challenge comes from DirecTV and a coalition of eight state attorneys general, who argue the merger would lessen competition and ultimately raise costs or reduce choices for consumers and distributors.

The Federal Trade Commission has announced settlements with three of the world’s largest advertising agencies—WPP, Publicis, and Dentsu—over allegations that they coordinated brand-safety standards in a way that excluded or disadvantaged media outlets based on political content. The case, filed in federal court in Fort Worth, Texas, is a significant signal that the FTC is willing to treat certain forms of industrywide content-related coordination as a competition problem, not merely a speech or platform-governance dispute.

According to the FTC, the agencies’ alleged conduct effectively created a boycott by steering advertising dollars away from publishers or platforms deemed politically objectionable under shared standards.

Defendants Compass, Inc. and United Real Estate Group have moved to stay proceedings in the Northern District of Illinois, asking the court to pause the case while related issues are resolved elsewhere. In practical terms, a stay motion is a request to put the litigation on hold—often to avoid duplicative work, inconsistent rulings, or expensive discovery that may prove unnecessary depending on developments in parallel proceedings.

Although the docket text is truncated, the context strongly suggests this filing arises out of the wave of real estate commission and broker compensation litigation that has followed the industry’s high-profile antitrust battles.

The Federal Trade Commission, joined by a coalition of states, has launched a significant enforcement action aimed at alleged collusion among major advertising agencies in the digital advertising market. The April 15 announcement is notable not just for the parties involved, but for where regulators are focusing next: beyond dominant technology platforms and into the intermediary ad ecosystem that influences pricing, placement, and competition across online media.

That matters because advertising agencies sit at a critical junction between brands, publishers, platforms, and consumers.

The Department of Justice’s Antitrust Division, alongside the U.S. Attorney’s Office for the Southern District of New York, has filed a civil antitrust suit against New York-Presbyterian, alleging the hospital system used contractual restrictions that limited access to lower-cost healthcare options. The case, United States Of America v. New York Presbyterian Hospital, is an important marker of where federal healthcare enforcement appears to be headed: closer scrutiny of contract terms that may steer patients away from cheaper alternatives and preserve market power for dominant providers.

According to the government, the challenged restrictions allegedly prevented health plans from offering or promoting more affordable options that would exclude or limit New York-Presbyterian’s participation.

One of the most closely watched healthcare merger disputes is still the Justice Department’s challenge to UnitedHealth Group’s proposed acquisition of Amedisys — and, just as importantly, the government’s willingness to resolve that challenge through a divestiture package rather than insisting on an all-or-nothing court fight.

The proposed settlement, reached with the U.S. Department of Justice and a coalition of state attorneys general from Maryland, Illinois, New Jersey, and New York, would require substantial asset sales to address competitive concerns tied to home health and hospice markets.

A federal judge in California has issued a preliminary injunction blocking the proposed $6.2 billion merger between Nexstar Media Group and TEGNA, handing enforcers and private challengers a significant early win in one of the most closely watched media antitrust fights in recent years.

The court found that the plaintiffs — including multiple state attorneys general and DirecTV — were likely to succeed on claims that the transaction would lessen competition, giving the combined company greater leverage over distributors and potentially leading to higher prices or worse terms that could ultimately affect consumers.

The U.S. Department of Justice Antitrust Division, joined by the U.S. Attorney’s Office for the Southern District of New York, has filed a civil antitrust case against The New York and Presbyterian Hospital, alleging the hospital used contractual restrictions that limited insurers’ ability to steer patients to lower-cost providers.

The case, United States Of America v. New York Presbyterian Hospital, is one to watch for healthcare providers, payors, and counsel advising on managed care contracting.

A federal judge in Connecticut has declined to pause the multistate antitrust litigation accusing generic-drug manufacturers of price-fixing, even as settlement discussions continue. The decision keeps one of the most closely watched coordinated state enforcement actions on an active track, preserving litigation pressure while negotiations unfold in parallel.

The case is part of the long-running generic-drug pricing litigation brought by a coalition of state attorneys general against multiple manufacturers.

The U.S. Department of Justice’s Antitrust Division, joined by the Ohio Attorney General, has filed a civil antitrust suit against OhioHealth, alleging the health system used contracting practices that unlawfully restricted competition and increased healthcare costs. The case, United States of America et al v. OhioHealth Corporation, puts a spotlight on how enforcers are continuing to scrutinize not just mergers, but also the day-to-day terms health systems negotiate with commercial payers.

That distinction matters.
