US Federal Trade Commission drafts complaint against Amazon over deceptive advertising practices
The FTC alleges Amazon misled advertisers on pricing mechanisms in its $68.6 billion ad business, escalating Washington's long-running battle with the e-commerce giant.
The Federal Trade Commission has been investigating Amazon, accusing the company of deceptive pricing practices that misled advertisers using its sprawling ad platform. The action targets how Amazon handled ad auctions and the transparency, or lack thereof, around what advertisers were actually paying for.
Amazon’s advertising arm generated $68.6 billion in revenue over the past year, making it one of the largest digital ad businesses on the planet, trailing only Google.
What the FTC is alleging
At the heart of the complaint are claims that Amazon used undisclosed “reserve pricing” in its ad auctions. Advertisers thought they were competing in a straightforward bidding process, but Amazon was allegedly setting hidden price floors that inflated what sellers had to pay without telling them the rules had changed.
The FTC’s consumer protection division had been building toward this action for months. A potential complaint was drafted as early as June 2026, with investigators zeroing in on how Amazon described the terms and pricing mechanisms of its sponsored listings program to the businesses buying ads.
The investigation also drew in several state attorneys general. State involvement can unlock penalties that exceed what federal regulators alone can impose, with state law penalties imposing daily fines for each violation, potentially pushing any fines or settlements into the billions.
As of August 2026, no formal complaint regarding deceptive advertising practices has been publicly recorded, despite the ongoing investigation.

A pattern, not an isolated incident
The FTC has already pursued significant action against Amazon. A $2.5 billion settlement tied to deceptive practices involving Amazon’s Prime subscription service — comprising a $1 billion civil penalty and $1.5 billion earmarked for consumer redress — demonstrated the commission’s willingness to pursue substantial penalties against the company. That Prime case centered on allegations that Amazon made it unreasonably difficult for consumers to cancel their subscriptions, employing manipulative design patterns.
Why advertisers should care
If the FTC’s allegations hold up, the hidden reserve pricing mechanism would mean that advertisers were paying more than they needed to in auctions where they believed they were competing on a level playing field.
The case could also force Amazon to overhaul how it structures and discloses its ad auction mechanics, which could change the economics of selling on Amazon for millions of merchants worldwide.
What this means for Amazon’s stock and the broader market
Amazon’s advertising segment has been one of the company’s most compelling growth stories, consistently outpacing the growth of the company’s retail and cloud computing divisions in percentage terms. A regulatory action that threatens to restructure how that segment operates, or levies billions in penalties, introduces uncertainty for investors. The $2.5 billion Prime settlement demonstrated that financial consequences from FTC actions are large and concrete.
The involvement of state attorneys general, with their capacity to impose daily per-violation fines, means the financial overhang from this investigation could be substantial.
