Amazon Marketplace Antitrust Price Inflation Litigation

This high-profile antitrust class action alleges that Amazon.com uses its dominant position as the largest U.S. online marketplace to illegally suppress price competition across the entire e-commerce ecosystem. Specifically, plaintiffs allege that Amazon's policies — including its "price parity" and "fair pricing" rules — effectively prohibit third-party sellers from listing products at lower prices on competing platforms such as Walmart.com, Target.com, or their own direct-to-consumer websites. Because sellers risk losing access to Amazon's coveted "Buy Box" and Prime eligibility if they undercut Amazon's prices elsewhere, they are compelled to raise prices on all competing platforms to match Amazon, artificially inflating the price floor for goods across the internet and harming hundreds of millions of American consumers.

The lawsuit, which mirrors a parallel Federal Trade Commission (FTC) antitrust suit filed against Amazon in September 2023, seeks to hold the company liable under the Sherman Antitrust Act for unlawfully maintaining its monopoly power to the detriment of consumers and market competition. Economists supporting the plaintiffs estimate that Amazon's anti-competitive pricing policies cost American consumers billions of dollars per year in artificially elevated prices. The case represents one of the most significant antitrust challenges to a technology company's core business practices in a generation and could, if successful, force Amazon to fundamentally restructure the rules governing its third-party marketplace.
