Nobody can predict Amazon’s ad reserve prices, including Amazon. That is the defence.

The FTC and 22 states sued Amazon, alleging its ad auctions cost advertisers $20bn+ since 2019. Amazon defended itself, stating reserve prices are unpredictable, even for itself. It claims ad performance improved over time, with lower winning bids and higher conversion rates. The case hinges on whether Amazon's auction descriptions were misleading. Amazon faces potential billions in penalties and another antitrust trial in 2027.
