Amazon Accused of Rigging Ad Auctions Through Secret Surcharge Scheme

The Federal Trade Commission dropped a bombshell this week, and the shrapnel is going to land on every advertiser who thought Amazon's marketplace was a level playing field. Reading the complaint feels less like reviewing a regulatory filing and more like watching a magician explain the trick after you've already paid for the show — the agency accuses Amazon of quietly pocketing billions by rewriting the rules of its own ad auctions.

The "Soft Reserve" That Ate Billions

According to the FTC, Amazon has run so-called "generalized second-price" auctions since 2012 — the same standard model the rest of digital advertising uses, where the top bidder pays just one cent more than the runner-up. Clean story, great marketing copy. The reality, the agency alleges, is uglier. In 2019, Amazon reportedly layered in a hidden adjustment it internally calls a "soft reserve price," overriding whatever the auction actually produced and replacing it with a number Amazon picked itself. The complaint, filed alongside 22 state attorneys general in the Western District of Washington, claims the company has executed "billions of rigged auctions" this way, tacking on what its own internal documents describe as "hidden" "surcharges" almost every time a shopper clicked a sponsored listing. The FTC's estimate of the haul: over $20 billion extracted from roughly 1.2 million advertisers since 2019.

A Coalition, and a Counterpunch

The bipartisan coalition behind the suit is unusually broad — 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 all signed on. The FTC is asking for a permanent injunction, civil penalties, restitution, and disgorgement of profits. Amazon, for its part, called the suit "misguided" and pointed to the FTC's six-year, 1.5-million-page review, arguing the agency leaned on "a handful of simplified communications" — including a few training videos — to spin a company-wide deception story. Amazon didn't deny the underlying mechanics of how its auctions run; it insisted the practice didn't harm advertisers or shoppers.

What to Watch Next

For anyone running a brand through Sponsored Products, Sponsored Brands, or Sponsored Display campaigns, this isn't just courtroom theater. If the FTC's theory holds, the cost calculus behind every keyword bid has been quietly inflated for seven years — meaning those tidy ROAS dashboards advertisers have been trusting may need a hard second look. Broader coverage of how regulators across other markets are now eyeing ad-tech accountability is unfolding over at Daily Business & Live News. Meanwhile, Amazon posted $200.6 billion in net sales last quarter on $62.6 billion in net income — exactly the kind of war chest that turns a "misguided" lawsuit into a multi-year chess match, and keeps the soft reserve very much in play.
