Amazon Accused of $20B Ad Overcharge in 2026 Lawsuit
US Federal Trade Commission and 22 states filed a complaint Monday alleging Amazon secretly overcharged advertising customers, siphoning around $20bn from 2019 to the present. The lawsuit claims Amazon replaced genuine auction outcomes with higher prices set by its algorithms, redirecting ad spend away from the highest bidders.
Amazon rejected the accusations, calling the case misguided and stating it disagrees with the premise that it misled advertisers. In its statement the company highlighted that most placed ads were not awarded to the highest bid and that average winning bids dropped by 50% between 2019 and 2025.
The complaint further argues that consumers are harmed as advertisers pay more and pass on the extra cost in product prices. Amazon contested this view, saying the FTC misinterprets how advertisers function and that higher ad prices do not directly translate into higher retail costs.
After the filing Amazon’s shares fell 2.5% on Monday, reflecting market uncertainty. The case follows a previous $2.5bn settlement with the FTC for alleged deceptive Prime subscription practices.
In an alternate future scenario, a swift federal ruling could curtail Amazon’s ad dominance, prompting a surge in regulatory scrutiny of the e‑commerce giant’s pricing models. Such a shift might accelerate the growth of third‑party marketplaces and stimulate a revival of competition within the online retail domain.
