Amazon Advertising Practices Under Fire as FTC Prepares Lawsuit

The Federal Trade Commission (FTC) is set to file a lawsuit against Amazon's advertising practices, according to a report from the Wall Street Journal. This move extends the FTC's enforcement efforts, which have so far focused on Amazon's marketplace and Prime services rather than its ad business.

Amazon's ad business is its fastest-growing and highest-margin revenue stream, making it a significant target for the FTC. Historically, antitrust and deceptive-practices complaints of this kind follow a multi-year process, including complaint, motion practice, discovery, before any durable repricing occurs.

The distinction between deception claims and monopoly-maintenance theories is worth noting. Deception claims tend to resolve in settlements, fines, or behavioral commitments, while monopoly-maintenance theories carry structural tail risk. The FTC's leadership has a history of pursuing expansive theories against large platforms, with a mixed litigation record.
