On August 31, 2026, the Federal Trade Commission (FTC), accompanied by a coalition of 22 state attorneys general, initiated a civil lawsuit against Amazon. The complaint alleges that Amazon engaged in practices that inflated advertising prices for its customers.

The lawsuit claims that Amazon secretly imposed undisclosed surcharges on advertisers. Additionally, it accuses Amazon of manipulating its advertising auction process, which resulted in elevated costs for advertisers using its platform.

The enforcement action was publicly announced through press releases issued by the participating state attorneys general offices. The legal filings detail the coalition's concerns regarding Amazon's advertising business practices and their impact on market pricing.
