GoKawiilFTC and 22 states sue Amazon over alleged ad auction price rigging
The FTC and a bipartisan coalition of 22 states have sued Amazon, claiming it secretly manipulated its advertising auctions to charge advertisers more than they should have paid under the stated 'second price' bidding rules. The complaint alleges Amazon pocketed roughly $20 billion since 2019 by making Sponsored Products advertisers pay their full winning bid nearly 80% of the time instead of one cent above the next-highest bid. Amazon has called the lawsuit 'misguided' and denies misleading advertisers or consumers.
GoKawiil's interpretation of the reporting above, not reported fact.
If proven, the case suggests one of the world's largest ad platforms quietly rewrote its own pricing rules to boost profit while advertisers believed they were competing under a transparent auction system. Regulators argue the hidden markup ultimately flows through to consumer prices, tying the case to broader antitrust scrutiny of Amazon's market power. A loss could force changes to how Amazon runs its multi-billion-dollar ad business and invite similar claims from advertisers seeking damages.
