The US Federal Trade Commission (FTC) and 22 states have filed a lawsuit claiming Amazon manipulated ad auctions to overcharge millions of customers by $20 billion since 2019.
- FTC and 22 US states allege Amazon manipulated online ad auctions.
- The alleged scheme resulted in $20 billion in excess revenue since 2019.
- Amazon is accused of charging winning bids instead of the 'second price' standard.
- Amazon denies the claims, calling the FTC's understanding of the market 'misguided'.
In a sweeping legal action, the US Federal Trade Commission (FTC) and a bipartisan coalition of 22 states have accused e-commerce giant Amazon of secretly overcharging more than a million advertising customers. The lawsuit, filed on Monday in Washington state, alleges that Amazon manipulated the online auctions used to set ad prices to artificially inflate its own profits.
According to the complaint, this systemic manipulation has likely netted the company approximately $20 billion since 2019. The FTC asserts that Amazon frequently overrode actual auction results, replacing them with higher prices set by the company itself. This action directly contradicts the expectations of advertisers who operate under the belief that they are participating in a fair, transparent bidding process.
Why This Matters
BozokMedia analysis shows that this case strikes at the heart of the 'black box' nature of ad-tech. By allegedly manipulating the 'second price' auction model—where winners typically pay just one cent more than the next highest bidder—Amazon is accused of eroding trust in digital marketplaces. If the FTC prevails, it could force a fundamental restructuring of how automated bidding works across the entire internet economy.
"The shift from transparent auction mechanics to opaque, company-controlled pricing represents a significant risk to competitive fairness in the digital age."
Amazon has responded aggressively to the allegations, stating that the FTC "fundamentally misunderstands" how the advertising market operates. The company argues that advertisers adjust their bids based on real-world performance metrics rather than the theoretical mechanics of the auction. Furthermore, Amazon claims that average winning bids for Sponsored Products search ads actually fell by 50% between 2019 and 2025.
Historical Background
This legal battle is the latest in a series of clashes between Amazon and the consumer watchdog. Just last year, Amazon settled a separate FTC case for $2.5 billion regarding allegations that it tricked millions of consumers into enrolling in Prime subscriptions and intentionally complicated the cancellation process. This pattern of litigation suggests a growing regulatory appetite to curb the dominance of the e-commerce behemoth.

Frequently Asked Questions
1. What is the 'second price' auction mentioned in the lawsuit?
It is a system where the winner pays one cent more than the second-highest bidder. The FTC alleges Amazon ignored this and charged the winner's own high bid nearly 80% of the time.
2. How does this affect the average Amazon shopper?
The FTC argues that when advertisers are overcharged, those costs are passed down to consumers through higher product prices, effectively acting as a hidden tax on shoppers.
