Bombshell suit claims Amazon cheated advertisers out of billions by secretly manipulating ad prices

A lawsuit alleges Amazon has secretly and systematically overcharged roughly 1.2 million advertising customers since 2019 by manipulating its ad “auctions” pricing. If proven, the claim implies significant damages exposure and potential regulatory/antitrust scrutiny over Amazon’s ad auction mechanics. The headline risk is high for ad-market economics and could pressure sentiment and valuation multiples.
