Amazon Falls 3.5% as FTC Prepares Advertising Lawsuit

Amazon.com Inc. shares fell 3.5% to a new intraday low after the Federal Trade Commission prepared to file a lawsuit accusing the e-commerce giant of deceiving its advertising clients, The Wall Street Journal reported.

The planned action, reported by The Wall Street Journal, targets Amazon's advertising operation, a business the company has expanded into a major profit driver alongside its retail and cloud units. The FTC has not yet filed the complaint, and the specific allegations were not disclosed.

The decline extended pressure on Amazon shares as investors weighed the regulatory threat to a segment that has become central to its earnings. The FTC's move follows its 2023 lawsuit against Amazon over Prime membership enrollment, which the company has contested in court.

A successful case could force Amazon to change how it sells and prices advertising, potentially reducing revenue and raising compliance costs across a business that has helped sustain profit growth. Amazon has said it will defend itself, and its response will shape how the shares trade in coming sessions.

Advertising Becomes a Regulatory Target

Amazon's advertising business has grown into one of its fastest-expanding segments, drawing scrutiny from regulators who have questioned how the company sells ad placements and measures performance for merchants. The FTC's investigation into whether Amazon deceived advertisers adds to a broader regulatory campaign against the company's marketplace practices.

The FTC has pursued Amazon on multiple fronts. In 2023, the agency sued Amazon over its Prime membership enrollment process, alleging the company used manipulative design to sign up consumers without consent. Amazon has disputed those claims, and the case remains in litigation. The agency has also examined Amazon's treatment of third-party sellers on its marketplace, including how the company uses merchant data and ranks products in search results.

What's at Stake

Advertising has become a key contributor to Amazon's operating income, and any forced changes to how the company prices or discloses ad placements could weigh on margins. Regulatory penalties, if imposed, would add to Amazon's legal costs, while compliance changes could slow the growth of a business that has helped offset thinner margins in retail.

The outcome also carries implications for the wider technology sector. Alphabet Inc.'s Google and Meta Platforms Inc., which operate the largest digital advertising platforms, face similar scrutiny from U.S. regulators, and a ruling against Amazon could set a precedent for how ad platforms disclose placement and pricing to merchants.

For Amazon, the timing is sensitive. The company has leaned on advertising and cloud computing to sustain profit growth as its core retail margins face pressure from competition and fulfillment costs. Any disruption to the advertising business would remove a key support for earnings at a moment when investors are already weighing a range of regulatory and competitive risks.

Amazon has not yet commented publicly on the reported lawsuit. The company's shares have been volatile as investors weigh the regulatory environment against its core retail, cloud, and advertising businesses. How the FTC frames its complaint, and how Amazon responds, will determine the near-term path for the stock.
