When Market Allocation Becomes Illegal: Antitrust Law and Territorial Agreements

When competing businesses agree to divide up markets, territories, or customers among themselves rather than competing for them, they cross one of the clearest lines in antitrust law. Market allocation agreements among competitors are among the most serious antitrust violations recognized under federal and state law. They eliminate competition as effectively as price fixing, and courts treat them as per se illegal, meaning that no amount of business justification can excuse them.

This article explains what market allocation agreements are, why they are illegal, how they are detected and prosecuted, and what businesses in Houston, The Woodlands, Spring, Cypress, Sugar Land, Missouri City, and Richmond need to know to avoid running afoul of antitrust law.

What Is Market Allocation?

Market allocation occurs when competing businesses agree among themselves to divide the market for their products or services rather than competing for the same customers. These agreements can divide markets by geography, by customer type, by product line, or by some other means. The essence of the arrangement is that each party agrees not to compete in certain areas or for certain customers in exchange for the other party’s agreement to stay out of their territory or customer base.

Examples of market allocation agreements include competitors agreeing that Company A will serve customers in Houston while Company B serves customers in Dallas, or that one company will focus on large commercial accounts while another focuses on residential customers. They can also involve agreements to allocate particular product segments to particular manufacturers, preventing each company from competing in the other’s product category.

Per Se Illegality Under the Sherman Act

Market allocation agreements between horizontal competitors, meaning businesses at the same level of the distribution chain who sell competing products or services, are per se illegal under Section 1 of the Sherman Act. This means that once a court finds that competing businesses agreed to divide markets, the violation is established regardless of whether the agreement had any procompetitive rationale or whether it actually harmed consumers in a measurable way.

The per se rule reflects the Supreme Court’s judgment that some agreements are so inherently anticompetitive that they should be condemned without further analysis. Market allocation agreements fall into this category because they directly suppress the competitive process by removing the threat of competition from one sector of the market or one group of customers.

Criminal and Civil Enforcement

Market allocation agreements can result in both criminal prosecution by the Department of Justice and civil litigation brought by private plaintiffs. The Antitrust Division of the DOJ treats horizontal market allocation as a criminal cartel activity, similar to price fixing and bid rigging. Individuals convicted of participating in such agreements can face significant prison sentences and fines. Corporations face substantial criminal fines that can be based on the volume of commerce affected by the agreement.

Private plaintiffs who have been harmed by market allocation agreements can bring civil suits under the Sherman Act and Texas antitrust law. Private antitrust plaintiffs can recover treble damages, meaning three times their actual damages, plus attorney fees. This potential for treble damages creates powerful incentives for private enforcement and means that even a modestly sized market allocation conspiracy can result in enormous civil liability.

Detecting Market Allocation Agreements

Antitrust enforcers use a variety of methods to detect market allocation agreements. These include leniency programs under which one participant in a cartel receives immunity from prosecution in exchange for cooperation and disclosure of the conspiracy. Cartel detection programs have been highly effective, and many antitrust prosecutions begin when one member of an agreement decides to cooperate with investigators.

Private plaintiffs can also gather evidence of market allocation through civil discovery, which in antitrust cases is often extensive. Emails, text messages, meeting notes, and testimony from participants and witnesses can establish the existence of an unlawful agreement even when the parties were careful to avoid formal written agreements.

Vertical Versus Horizontal Agreements

An important distinction in antitrust law is between horizontal agreements, which involve competitors at the same level of the market, and vertical agreements, which involve parties at different levels of the distribution chain, such as a manufacturer and its distributors.

While horizontal market allocation among competitors is per se illegal, vertical territorial restrictions imposed by a manufacturer on its distributors are analyzed under the rule of reason. Under this more flexible standard, courts examine the pro-competitive and anticompetitive effects of the restraint to determine whether it is on balance lawful. Manufacturers have legitimate business reasons for assigning exclusive territories to distributors, and such restrictions are generally permissible if they promote interbrand competition even while limiting intrabrand competition.

The distinction matters enormously in practice. A manufacturer telling its distributors that each has an exclusive territory is generally lawful. Competing distributors getting together and agreeing to divide territories among themselves is per se illegal.

Hub and Spoke Conspiracies

Modern antitrust enforcement has grappled with so-called hub and spoke conspiracies, in which a central actor, the hub, facilitates market allocation agreements among competitors, the spokes. If a platform, trade association, or major buyer effectively organizes competitors to divide markets or customers, all participants, including the hub, can be liable under Section 1 of the Sherman Act.

Hub and spoke theories have been applied in cases involving online platforms, trade associations, and industry groups that gathered and exchanged competitively sensitive information among rivals. Businesses that participate in trade associations or industry groups should be cautious about discussions that could be interpreted as coordination on markets, territories, or customers.

Texas Antitrust Law

Texas has its own antitrust statutes, including the Texas Free Enterprise and Antitrust Act, which closely follows the federal Sherman Act framework. Market allocation agreements among competitors are illegal under Texas law as well as federal law, and the Texas Attorney General has authority to bring enforcement actions. Private plaintiffs can also bring state antitrust claims, often in conjunction with federal Sherman Act claims.

Compliance Programs and Risk Management

Businesses that operate in competitive industries should maintain robust antitrust compliance programs. These programs should include training for sales and marketing personnel on what they can and cannot discuss with competitors, policies on trade association participation, and protocols for handling competitively sensitive information. For businesses in Houston and throughout Texas, effective antitrust compliance reduces the risk of inadvertent violations that could result in criminal prosecution or costly civil litigation.
