FTC, 22 US States Sue Amazon Over Alleged $20 Bn Ad Auction Manipulation - outlookbusiness.com
The FTC and 22 US states filed suit against Amazon in September 2026 alleging the company manipulated its ad auction system to inflate advertiser costs by approximately $20 billion. Sellers and brands running Sponsored Products, Sponsored Brands, or DSP campaigns on Amazon are the direct targets of this alleged overcharge.
This is the most significant regulatory challenge to Amazon's advertising business to date, adding to broader platform consolidation risk — if Amazon is forced to restructure ad auctions, it reshapes the entire third-party seller cost structure and competitive ad dynamics on the platform.
If the auction was rigged, your historical ACOS and TACOS benchmarks are built on inflated baselines — meaning your 'efficient' campaigns may have been systematically overpriced. Pull your Sponsored Products Search Term Report for the last 12 months and flag any campaigns where CPC spiked without corresponding conversion rate changes, as these could reflect artificial price floors.
