The Attorney General’s Antitrust Division

The Antitrust Division protects our economy by investigating and challenging anticompetitive practices and agreements that harm consumers, workers, and businesses.

Free market competition is the basis of a strong and vibrant economy.  The Antitrust Division is responsible for investigating and challenging anticompetitive conduct that undermines that free market competition. Through its work, the Antitrust Division helps preserve competitive markets and a level playing field to protect consumers, workers, and businesses from anticompetitive conduct and agreements.

The Antitrust Division enforces state and federal competition laws to oppose a variety of anticompetitive practices.  For example, the Division seeks to block mergers and acquisitions that would substantially lessen competition, harming consumers and workers through higher prices, decreased wages, decreased choice, and decreased quality and innovation. The Division challenges companies that unlawfully monopolize industries through anticompetitive tactics.  The Division brings lawsuits to root out agreements in restraint of trade among competitors to unlawfully fix prices, allocate markets, rig bids, or share competitively sensitive information.  And the Division advocates for fair competition policy at the state and national level by filing legal briefs in antitrust cases, engaging in policy initiatives, and promoting procompetitive legislation.

To report anti-competitive mergers, price-fixing agreements, and other illegal practices, or otherwise contact the Division, please email [e-mail] or call [phone].
