“Amazon rigged billions in ad pricing, lawsuit from states and US watchdog alleges”
What actually happened
The Federal Trade Commission and a bipartisan group of 22 state attorneys general sued Amazon on Monday, alleging it secretly overcharged advertisers by manipulating the "second-price" auctions used to set Sponsored Products ad rates. The FTC's own case page confirms the filing: "FTC and 22 state attorneys general allege Amazon concealed unfair charges in its digital advertising auction pricing." Amazon disputes the characterization and says the suit misunderstands how advertising bidding actually works.
Key facts
- Scale alleged: the FTC and states say in their lawsuit filed Monday that the alleged scheme has likely netted the company $20bn from advertising customers since 2019
- Auction mechanic disputed: in a true second-price auction advertisers expect to pay one cent more than the next highest bidder, but the complaint alleges Amazon has charged its Sponsored Products advertisers their own winning bid close to 80% of the time
- Filing details: the suit was filed in the U.S. District Court for the Western District of Washington, with the FTC commissioner vote authorizing it going 2-0
- Advertisers affected: other outlets covering the same complaint put the figure at 1.2 million advertising customers, close to the BBC's "more than a million"
- Amazon's rebuttal, cited in the article: the company says "Average winning bids fell 50% from 2019 to 2025 on Sponsored Products search ads, and roughly 92% of placed ads are not given to the highest bid"
- Market reaction: shares closed 2.5% lower on Monday following the announcement
- Prior FTC history: Amazon settled a related consumer-protection case with the FTC last year for $2.5bn over Prime enrollment and cancellation practices
What to watch for
Watch whether internal Amazon documents cited by other outlets, alleging staff discussed raising prices while "hoping advertisers wouldn't notice," surface more prominently as the case proceeds; that detail would sharpen the "rigged" framing considerably if borne out in discovery. Also watch how Amazon's "92% not given to highest bid" defense holds up against the FTC's "80% charged own winning bid" claim, since these are not strictly contradictory but muddy the picture for casual readers.
