Amazon stock
Amazon.com Inc. (AMZN) shares declined approximately 3% on August 31, 2026, following reports that the Federal Trade Commission (FTC) and over 20 state attorneys general are filing an antitrust lawsuit against the company. The litigation alleges that Amazon manipulated its advertising auction system over a seven--year period to "secretly raise the minimum price" businesses paid for ad placements. This regulatory challenge specifically targets Amazon's high--margin advertising segment, which has been a primary driver of the company's recent operating income growth and valuation.
