Antitrust Laws
Critically important but commonly misunderstood, antitrust laws are meant to promote competition and protect consumers. Here’s everything you need to know.

America's antitrust laws protect competition and benefit consumers.
Antitrust laws ensure competition in a free and open market economy, which is the foundation of any vibrant economy. And healthy competition among sellers in an open marketplace gives consumers the benefits of lower prices, higher quality products and services, more choices, and greater innovation.
The core of U.S. antitrust law was created by three pieces of legislation: the Sherman Antitrust Act, the Federal Trade Commission Act, and the Clayton Antitrust Act. These laws have evolved along with the market, vigilantly guarding against anti-competitive harm that arises from abuse of dominance, bid rigging, price fixing, and customer allocation.
