The U.S. Federal Trade Commission is preparing to file a lawsuit against Amazon, alleging the company deceived advertisers regarding its ad auction mechanics and pricing. Multiple state attorneys general are reportedly involved in the coordinated effort.
The lawsuit could result in significant civil fines for Amazon and potentially force changes to its advertising system, impacting its substantial advertising revenue and affecting advertisers' costs and strategies on the platform.
The U.S. Federal Trade Commission intends to file a lawsuit against Amazon, alleging the company misled advertisers about the workings of its ad auctions and pricing, according to a report by The Wall Street Journal citing agency officials. The complaint, which could be filed in the coming weeks, scrutinizes how Amazon communicates terms, pricing, and reserve pricing in its search advertising and sponsored listings businesses.
This investigation, which originated as a consumer protection probe in 2025, specifically targets transparency issues within Amazon's advertising operations. Regulators are examining the company's disclosures regarding reserve pricing, the minimum price required for an ad to be displayed. Multiple state attorneys general are reportedly involved in this coordinated effort.
Amazon has a history of regulatory scrutiny from the FTC. In September 2025, the company agreed to a $2.5 billion settlement related to a separate complaint about its Prime subscription practices, which alleged difficulties for consumers in canceling their memberships. Amazon's advertising business has seen significant growth, becoming a major revenue source and positioning it as the third-largest digital advertising platform in the U.S., behind Google and Meta. The FTC is also conducting a parallel investigation into Google's advertising practices, indicating a broader concern about systemic issues in the digital advertising ecosystem.
For Amazon investors, a substantial civil fine could impact earnings. Furthermore, any restructuring of Amazon's ad system that leads to lower ad prices or a less favorable auction system could have a lasting effect on revenue. The FTC commissioners are expected to vote on the matter, with a resolution anticipated by summer 2026.
