Customer and Market


A customer or market allocation conspiracy is an agreement by competitors to divide markets or customers for a product or service. The purpose of the agreement is to eliminate competition for each competitor’s designated share of the market.

Customer or market allocation may be accomplished by allowing each competitor the exclusive right to deal with specific:

  • customers or classes of customers,
  • geographic portions of a market, or
  • portions of a market divided by percentages or numbers of customers.

A market division scheme can also involve an agreement among participants to refrain from competing for each other’s existing customers or markets.

Regardless of how the scheme is carried out, the result is a virtual monopoly by each conspirator for that conspirator’s designated market share. This eliminates competition for pricing as well as for customers or territories. Conspirators can then charge their respective customers higher prices without risk of being undercut by their competitors.

Kohn Swift’s antitrust lawyers represent businesses and consumers harmed by illegal customer and market allocation schemes.



Market allocation is a form of agreement not to compete. Agreements not to compete that unreasonably hinder competition may violate both federal and state antitrust laws.

Horizontal market division schemes (those among direct competitors) violate the Sherman Act by:

  • eliminating competition among conspiring competitors, and
  • keeping other competitors from a market.

In federal antitrust actions brought under the Sherman Act, courts award successful claimants reasonable attorneys’ fees and monetary damages equal to three times their actual losses. In appropriate cases, a court may also order the defendants to cease any further activity related to the prohibited conspiracy. Plaintiffs in private customer and market allocation antitrust actions may also receive damages and injunctive relief under certain states’ antitrust laws.
