FTC sues Amazon, alleging it overcharged advertisers
FTC and 22 States Take Amazon to Court Over Alleged $20 Billion Ad-Pricing Scheme
Qwenews.com – The Federal Trade Commission, joined by 22 state attorneys general, filed suit on Monday accusing Amazon of systematically inflating what advertisers pay to place promotions across its retail marketplace. At the heart of the complaint is the claim that roughly 1.2 million businesses were charged more than they understood they were paying, because Amazon quietly raised the floor price for ad placements without notifying those advertisers. The agency estimates the scheme extracted more than $20 billion over several years, with nearly half of affected accounts belonging to small or medium-sized enterprises.
How the Auction Was Supposed to Work — and Where Amazon Allegedly Broke It
Digital advertising on major platforms typically runs through a real-time auction: advertisers submit bids for specific ad slots, and the highest bidder wins the placement. Under standard auction mechanics, the winner pays only one cent above the second-highest bid, keeping costs competitive and transparent. The FTC's complaint alleges that beginning in 2018, Amazon departed from that framework by secretly manipulating auction outcomes to drive prices upward. Specific tactics cited include embedding a hidden surcharge into final invoices and injecting artificial competing bids that had no genuine advertiser behind them.
The agency further contends that the inflated advertising costs did not stay contained within marketing budgets. Instead, Amazon folded the extra expense into product pricing, meaning everyday shoppers effectively subsidized the overcharge through slightly higher retail prices on goods they purchased.
Amazon's Rebuttal
In a lengthy statement issued to media outlets, Amazon pushed back forcefully, calling the suit "misguided" and saying it "strongly disagrees" with the FTC's core premise.
"The FTC's claim fundamentally misunderstands how advertisers operate. Advertisers adjust bids based on real-world performance, not descriptions of auction mechanics. Even accepting the FTC's flawed premise that advertisers do not adjust bids, we estimate they saved over $8 billion from 2021 to 2025 as a result of Amazon prioritizing ad relevancy over selecting ads on bid price alone."
The company also asserted that it had shared relevant data with the FTC "on multiple occasions," yet characterized the agency as showing "little interest in engaging with the facts" and appearing "more focused on trying to secure some sort of monetary victory." Amazon added that its digital-advertising costs, when adjusted for inflation, had remained essentially flat even as conversion rates improved during the same period.
Why Auction Integrity Matters in Digital Advertising
Auction-based ad buying is a foundational practice across the digital advertising ecosystem. Its legitimacy depends on platforms adhering strictly to well-established rules that keep bidding competitive and outcomes predictable. Vamsi Kanuri, a marketing professor and strategist at the University of Notre Dame, noted in commentary that any deviation from those rules undermines trust not just in one platform but in the broader auction model that underpins programmatic advertising worldwide.
Even setting aside transparency questions, Amazon's sheer scale makes departure difficult for advertisers. Emarketer principal analyst Zak Stambor observed that the company generates approximately $927.82 billion in worldwide retail e-commerce sales this year, giving it a gravitational pull that few rivals can match.
"Advertisers face a tough challenge because Amazon is incredibly hard to walk away from," Stambor said.
That lock-in dynamic is precisely what regulators worry about: when a single platform controls both the storefront and the advertising inventory, advertisers may lack realistic alternatives to test whether pricing is fair.
A Pattern of Federal Enforcement
This is the third major lawsuit the FTC has brought against Amazon since the company rose to become the third-largest advertising platform in the United States in 2018. The prior two cases illustrate the breadth of the agency's scrutiny:
In 2024, Amazon settled a case first filed in 2023 under the Biden administration for a record $2.5 billion. The complaint alleged the company tricked consumers into enrolling in Prime subscriptions and then made cancellation deliberately difficult. Amazon agreed to pay a $1 billion civil penalty — the largest ever imposed for an FTC rule violation — plus $1.5 billion in refunds to an estimated 35 million customers "harmed by their deceptive Prime enrollment practices."
Separately, in 2023, Amazon resolved FTC claims over user-privacy violations for more than $30 million. Alexa voice assistants and Ring doorbell cameras were accused of retaining users' video clips, voice recordings, and geolocation data for years beyond what consumers expected. Amazon denied wrongdoing in both matters.
What Comes Next
The new suit, if it proceeds through litigation, will test whether auction-manipulation claims can be sustained under existing consumer-protection statutes and whether the FTC can recover billions in alleged overcharges from advertisers. For the small and medium businesses that made up nearly half of the affected advertiser base, the outcome could determine whether they receive restitution or remain locked into a pricing structure they never fully understood. The FTC has not yet indicated a timeline for trial, and Amazon has signaled it will contest the case vigorously.
