The United States Federal Trade Commission (the FTC) enforces federal antitrust laws through its Bureau of Competition. The two most significant sources of the the FTC’s antitrust authority are the FTC Act and the Clayton Act. (The FTC also has statutory powers to enforce consumer protection laws, an area outside the scope of this overview.) The FTC Act prohibits unfair methods of competition, which includes, but is not limited to, any conduct that violates the Sherman Antitrust Act. The Clayton Act prohibits corporate acquisitions that may tend substantially to lessen competition.
