Antitrust Law Explainer
Antitrust law seeks to protect competition, not individual competitors. In the United States, the Sherman Act addresses agreements that unreasonably restrain trade and monopolization, the Clayton Act reaches mergers and practices that may substantially lessen competition, and the FTC Act prohibits unfair methods of competition.
Certain agreements among rivals, such as price fixing, bid rigging, and market allocation, can create severe civil and criminal exposure. Other conduct is evaluated in context, including market power, competitive effects, business justification, and available alternatives. Legitimate collaboration still requires careful design.
Merger review asks whether a transaction may reduce competition through higher prices, lower output, weaker innovation, worse quality, reduced labor competition, or exclusion of rivals. Agencies examine market structure, entry barriers, direct evidence, bargaining, vertical relationships, and platform effects rather than relying on one metric.
Remedies can include injunctions, divestitures, conduct requirements, damages, and criminal penalties. Compliance should cover communications, pricing, information exchange, trade associations, hiring, distribution, and deal planning. Because facts and jurisdiction matter, businesses should obtain qualified legal advice before sensitive coordination.
The law protects the competitive process and customers, workers, and trading partners.

Price fixing, bid rigging, and market allocation can trigger criminal enforcement.
Informal conversations and signals can create evidence of agreement.
