New York joins $20 billion Amazon advertising lawsuit - fingerlakes1.com
New York has joined a multistate $20 billion lawsuit against Amazon's advertising practices, escalating regulatory pressure on the platform's ad business. This adds significant legal weight to antitrust claims that Amazon inflates ad costs and manipulates auction dynamics.
This is part of a broader regulatory wave targeting platform advertising monopolies, similar to EU DSA enforcement and FTC actions — long-term, it could force Amazon to open ad data or restructure auction transparency, reshaping how brands compete on-platform.
If courts force Amazon to restructure ad auctions or cap certain fees, CPCs across Sponsored Products and Sponsored Brands could shift dramatically — brands with heavy ad dependency face the most volatility. Pull your Advertising Cost of Sale (ACoS) trends monthly and model scenarios where ad costs drop 10-20% or auction rules change.
