[{"source":"Federal Trade Commission - Protecting America's Consumers","url":"https://www.ftc.gov/news-events/news/press-releases/2026/08/ftc-states-sue-amazon-over-secret-ad-surcharge-scheme","description":"Today, 22 states joined the Federal Trade Commission in filing suit against Amazon, alleging that the company engaged in deceptive and unfair practices that secretly inflated prices in its online search advertising auctions. The complaint   alleges that, for over seven years, Amazon has covertly and substantially increased the prices that more than one million brands and sellers were required to pay to advertise on its platform. As a result, the complaint alleges that Amazon’s scheme has likely extracted tens of billions of dollars from its unwitting advertising customers. “When one of the world’s largest online retailers engages in unfair and deceptive conduct, the impact can be staggering,” said Chairman Andrew N. Ferguson. “Amazon has millions of advertising customers who were misled into paying significantly higher prices. These higher costs were largely passed on to American consumers. The FTC under President Trump won’t allow this deception to continue.” The FTC, along with the attorneys general of Alaska, Arizona, California, Colorado, Florida, Idaho, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maryland, Nebraska, New Jersey, New York, North Carolina, Oklahoma, Pennsylvania, Rhode Island, South Carolina, Vermont and Washington, allege Amazon has imposed undisclosed surcharges on its advertising customers, which include over 500,000 small- and medium-sized businesses that participated in auctions for advertising placements on Amazon.com and its mobile app. In these auctions, prospective advertisers bid to place Sponsored Product ads, Sponsored Brands ads and Display Ads alongside the results that appear when a consumer searches for a product using a keyword on Amazon’s store. Placements are auctioned to the highest-ranked bidder for each keyword. As described in the complaint, Amazon has represented to prospective advertisers for years that Amazon runs “second price” auctions where the winner of the auction would only pay “one cent more than the next highest bidder” for each successful bid for an advertising keyword. However, in practice, the complaint alleges that Amazon has charged its Sponsored Products advertisers their own winning bid close to 80% of the time and has effectively converted its nominally “second price” auction into a first price auction. According to the complaint, Amazon’s “second price” auctions have been described by Amazon, and understood by advertisers, to be run as generalized second-price, or GSP auctions, which have been the accepted industry standard for digital advertising placements. The complaint states that Amazon has made these or similar representations on its website, in training videos and in other public-facing materials, as well as in presentations made to advertisers by its hundreds of sales personnel.  The type of auction matters to advertisers because it impacts how they bid. In a sealed first-price auction—the type of auction where winners pay the amount of their winning bid—bidders run the risk that they might overbid. So, in repetitive auctions for the same goods, they will often reduce their bid to determine what the minimum amount needed to win future auctions might be. This is called bid shading. In second-price auctions, bidders are more likely to bid higher, closer to their true value for the product, because they will only be liable to pay the least bid amount needed to win under the auction’s rules.  As alleged in the complaint, Amazon told advertisers it ran a GSP, but for years its auction pricing had “a surcharge hidden in it,” in the words of one internal Amazon document. The complaint alleges that, beginning in 2019, Amazon changed its auction rules without notice by adding an undisclosed surcharge that Amazon referred to internally as a “soft reserve price.” This resulted in advertisers paying substantially more than the price determined by the GSP auction.  According to the complaint, Amazon","titre":"FTC, States Sue Amazon Over Secret Ad Surcharge Scheme","id":3127461,"pubDate":"Tue, 01 Sep 2026 08:10:10 +0200"}]
