Court documents were submitted to the U.S. District Court located in Washington’s Western District.
The Core Allegations
The legal filing focuses on three advertising categories: sponsored product listings, branded advertisements, and display advertising units. These advertisements populate search result pages when customers browse products on Amazon.
Federal regulators assert that Amazon modified its auction mechanisms in 2019 before discreetly implementing measures that raised the floor prices required to secure advertising positions.
The complaint details how Amazon allegedly submitted its own competitive bids within these auctions, artificially inflating expenses for competing advertisers who remained unaware of this practice.
Regulators contend that Amazon manipulated up to 80% of auctions for sponsored product advertisements.
As advertising expenditures climbed, businesses compensated by increasing product prices, ultimately transferring these elevated costs to shoppers, according to the FTC’s argument.
Federal authorities calculate that advertisers faced overcharges totaling no less than $20 billion and are pursuing total compensation reaching “tens of billions.”
Amazon’s Response
Amazon refuted these claims through an official blog statement released Monday.
The corporation maintained that its advertising framework prioritizes displaying the most pertinent ads to customers rather than artificially increasing expenses.
Amazon stated that average per-click costs remained unchanged between 2019 and 2024, while revenue generated from those clicks actually increased.
The company further claimed it delivered approximately $8 billion in savings to advertisers from 2021 through 2025, noting that average successful bids for sponsored product search advertisements declined 50% from 2019 to 2025.
“Amazon’s approach to pricing contradicts any suggestion of consumer harm,” the company said.
Amazon currently defends itself in another FTC lawsuit concerning alleged monopolistic pricing strategies and practices involving third-party marketplace sellers, with trial proceedings scheduled for next year.
In the previous year, Amazon reached a $2.5 billion settlement with the FTC regarding allegations that it misled consumers into Prime membership subscriptions.
Amazon currently ranks as the third-largest digital advertising platform globally, trailing only Google and Meta. The company’s advertising revenue surged 26% during this year’s second quarter, reaching $19.8 billion.
Amazon stock declined approximately 2.5% Monday after the lawsuit announcement became public.
