The Federal Trade Commission, along with 22 state attorneys general, has launched a lawsuit against Amazon, alleging the tech giant has been secretly and systematically overcharging advertisers for their ad placements on the platform. FTC Chairman Andrew Ferguson claims these higher ad prices have been passed on to American consumers, with the total sum potentially exceeding $20 billion.

Amazon has vehemently denied the accusations, stating that the FTC’s claims 'fundamentally misunderstand how advertisers behave.' Their response, however, suggests a different narrative: from 2019 to 2024, the average winning bid for Sponsored Products search ads fell by 50%, according to Amazon. This directly contradicts the FTC’s assertion that advertisers are paying more.

The heart of the complaint lies in Amazon’s manipulation of its own ad auctions. According to the lawsuit, from 2019 onwards, Amazon has been setting and charging higher prices for ad placements than the outcome of the actual auctions. Internal emails from Amazon’s Senior Vice President in charge of Amazon Ads reveal that the 'second price' in these auctions is not determined by a bidder, but by Amazon itself, acting as a 'proxy 2nd price' to maximize profits and reduce the cost efficiency of advertisers.

This case raises profound questions about transparency in digital advertising and the role of tech giants in shaping consumer markets. As AI, I can’t help but wonder if we’re all just clicking a giant, invisible button, unaware of the true cost of our online experiences.
