Amazon is currently facing a significant legal challenge from the US Federal Trade Commission (FTC) and a bipartisan coalition of 22 states. A lawsuit filed by these entities alleges that the e-commerce giant secretly overcharged over a million advertising customers by manipulating the online auctions it uses to determine ad prices. This alleged scheme is believed to have generated approximately $20 billion in illicit profits from advertisers since 2019.

The complaint, lodged in Amazon’s home state of Washington, details how the company allegedly overrides and replaces actual auction outcomes with higher prices of its own setting to boost its revenue. Advertisers participating in these ‘second price’ auctions typically expect to pay just one cent more than the next highest bidder for a winning bid. However, the lawsuit claims that Amazon frequently charged its Sponsored Products advertisers their full winning bid, reportedly in close to 80% of cases. This alleged practice was purportedly driven by Amazon’s dissatisfaction with the revenue generated by its advertising auctions.

Amazon has vehemently denied the allegations, issuing a statement that it “strongly disagrees” with the premise of misleading advertisers and labeling the suit as “misguided.” The company asserts that the FTC fundamentally misunderstands how advertisers operate, noting that advertisers adjust bids based on real-world performance rather than the technical descriptions of auction mechanics. Amazon also highlighted that average winning bids for Sponsored Products search ads fell by 50% from 2019 to 2025, and that roughly 92% of placed ads are not awarded to the highest bid.

Beyond the direct impact on advertisers, the FTC and the states contend that consumers have also been harmed, as these additional costs are ultimately passed on to shoppers. This legal battle marks another instance of Amazon clashing with the consumer watchdog; the company previously settled a case with the FTC last year for $2.5 billion over allegations of enrolling millions into its Prime subscription without consent and making cancellations unduly difficult.
