📅 2026 Update: Recent Developments in Antitrust Laws

Since the original article was written, there have been important updates in US antitrust laws and enforcement. The Federal Trade Commission (FTC) and the Department of Justice (DOJ) have introduced new guidelines and continued to take action against companies for antitrust violations. The earlier article continues further down the page.

🏛️ New Merger Guidelines

In 2023, the FTC and DOJ released new Merger Guidelines. These guidelines were created after two years of feedback from the public and staff. They focus on how to review mergers and acquisitions to avoid harming competition.

📉 Criminal and Civil Penalties

The penalties for antitrust violations have remained serious. Corporations can face fines up to $100 million. Individuals could be fined up to $1 million and may serve up to 10 years in federal prison.

Civil penalties can sometimes reach into the billions, depending on the situation.

🔍 Ongoing Enforcement Actions

In late 2025, the DOJ filed a proposed settlement against RealPage Inc. This case is about rental pricing software that allegedly helped landlords coordinate rents. It highlights the ongoing scrutiny of companies that may be engaging in anticompetitive practices.

📜 Types of Agreements Reviewed

Horizontal agreements, like price-fixing and bid-rigging, are treated as per se violations. This means they are illegal regardless of their effect on competition. In contrast, vertical agreements are evaluated under the Rule of Reason, which looks at their actual impact on competition.

📌 Key Takeaways

  • The FTC and DOJ issued new Merger Guidelines in 2023.
  • Criminal penalties can reach up to $100 million for companies.

Introduction


Per se violations refer to acts or behaviors that violate antitrust laws inherently without the need to prove anti-competitive effects. These types of violations are considered to be so harmful to competition that they are deemed illegal per se, meaning they are presumed to be illegal without the need for further analysis. In this article, we will explore per se violations, their importance, and their application.

What are Per Se Violations?


Per se violations refer to certain business practices that are deemed illegal by antitrust law. These violations are illegal per se because they have been deemed to be so harmful to competition that their impact is deemed inherently illegal. Per se violations require no showing of actual anticompetitive effects or market analysis because they are considered naked restraint of trade agreements that are inherently anticompetitive and against the public good.

Examples of Per Se Violations


Some of the most notable examples of per se violations include price-fixing agreements between competitors, market allocation between competitors, horizontal agreements between competitors that lead to market sharing, bid rigging, and group boycotts. All of these agreements have been deemed per se violations and are typically illegal without exception, regardless of any potential justifications or competitive benefits.

Why are Per Se Violations Important?


Per se violations are important because they embody the most damaging forms of anti-competitive agreements and behaviors. By designating certain behaviors as per se violations, antitrust laws create a bright line rule that is easy for businesses and courts to understand and apply. This allows for quick resolution of antitrust cases in instances where businesses engage in these illegal practices.

Application of Per Se Violations


To prove a per se violation, the plaintiff will need to prove that the parties agreed to a naked restraint of trade. This implies that the agreement did not involve any pro-competitive benefits, and it is anti-competitive on its face. Once the plaintiff establishes that the agreement is a per se violation, the burden of proof shifts to the defendant, who must defend the agreement by showing there were competitive benefits that outweighed any anti-competitive impact.

Conclusion


Per se violations are essential to antitrust law as they define some of the most harmful, anti-competitive behaviors that pose a significant threat to the competitive integrity of the economy. By prescribing legal action against these agreements and behaviors, antitrust law aims to protect competition, promote consumer welfare by ensuring transparency and maintaining open markets. Ultimately, per se violations are an essential tool in antitrust law enforcement, and businesses should be mindful of their implications to avoid violating these laws.

The Sherman Antitrust Act covers a wide variety of different business practices that can be considered to constrain interstate commerce. Even though the Sherman Act was written into law in 1890, the forms of antitrust law are readily applicable today.

There are a wide variety of different forms of abuses a business can undertake to violate antitrust law. However, the judicial response to such violations come under the consideration of the per se form of logic or rule of reason method. Antitrust law that falls under the per se form of logic are infractions that are blatantly and inherently obvious to judicial officials, as well as the judiciaries investigators.

Usually per se violations that violate antitrust law, which are the most common, are price fixing or bid rigging. Both practices are inherently against the freedom of interstate commerce. Price fixing occurs when two or more companies collude to set a standard price; usually obscenely low, then moving up to a higher price. Initially rival companies within the same market can conspire or even enter into written agreements to both artificially set the price of their goods low, very low in some cases.

While it may cause a financial loss to the companies initially, it can be made up on the back end by driving up the price. Setting the price low and controlling the majority of the market share between the two rival companies will force their smaller competitors out of business. Once their competitors are out of business, they can then set the price higher while retaining a larger market share for both entities, gaining financially in the process. This seriously constrains interstate commerce, as many of the smaller competitors cannot sustain the artificially lower price.

The other form that usually violates antitrust law concerns bid rigging. Companies do not control every stage of their manufacturing process. In many cases, this is contracted out to smaller firms to, for example, make the metal that will be used to form a car door. Bid rigging occurs when the car manufacturer conspires with a metal plant prior to an open competition for the contract. In these cases, both the car manufacture and the conspiring metal works plant win.

Instead of an open, fair competition, a manufacturer already knows the contract will come to them since they made certain concessions and deals in backdoor meetings with the entity selling the contract. While this will benefit those two parties, it restrains interstate commerce since the other viable options for the contract have, in essence, already been excluded from the process. While a charade of bid selection may occur to give the illusion of legality, the outcome is already decided.

Both forms of violations fall under the per se rule since they are obvious infractions to interstate commerce, restraining the ability of competitors to operate within the framework of a fair free market. While these examples simply illustrate restraints on interstate commerce, the same logic applies to foreign trade or commerce as well. Since the Sherman Act is a Federal statue, all violators of antitrust law are charged and prosecuted with felonies.
