FTC and 22 State AGs, Including Colorado, Sue Amazon for Manipulating Ad Auctions and Overcharging Advertising Customers

1,200,000

Summary

Colorado Attorney General Phil Weiser joined the FTC and 22 state attorneys general in filing a lawsuit against Amazon for manipulating the auctions used to set advertising prices, replacing actual auction results with higher prices since 2019 and overcharging nearly 1.2 million U.S. advertising customers. The FTC estimates total improper surcharges from 2018 to 2026 exceed $20 billion, with costs ultimately passed to shoppers through higher prices. The states seek a permanent injunction and monetary relief; no penalty has been imposed yet as this is a newly filed complaint.

Remedy

The states are asking the court to grant a permanent injunction to prevent future violations of their consumer protection laws, award monetary relief within the court's authority for the overcharged advertising customers, and any additional relief the court determines to be just and proper. No fine or settlement has been entered yet because the complaint was just filed.

InjunctionMonetary Penalty

Contract Impact

In-house teams should review advertising services agreements, media buying contracts, and marketplace/seller agreements with Amazon and comparable ad platforms (e.g., Google, Meta, Walmart Connect) for pricing transparency and fee integrity protections. Key clauses to examine include: representations or warranties that ad prices are determined by genuine competitive auctions; disclosure obligations covering all fees, surcharges, and post-auction price adjustments; audit rights over ad spend and underlying auction data; cost pass-through provisions that shift advertising costs into customer or consumer prices; indemnification and remedy clauses for overcharges or deceptive pricing practices; and compliance-with-law provisions that expressly cover state consumer protection acts such as the Colorado Consumer Protection Act. Companies that resell advertising services or allocate platform ad costs to clients should also check customer contracts for pricing adjustment and fee disclosure terms that may need updating in light of alleged auction manipulation.

A federal court approved a revised order in the FTC's Amazon Prime case under which Amazon will accelerate and expand redress payments under the September 2025 $2.5 billion settlement, which resolved allegations that Amazon enrolled millions of consumers in Prime subscriptions without their consent and knowingly made cancellation difficult. More consumers now qualify for refunds, the maximum payment cap rises from $51 to $200, and all future payments will be distributed automatically starting October 1, 2026, with potential supplemental $149 payments by April 2027. Amazon has already issued more than $845 million in redress payments as of September 2026.

TX

Amazon.com, Inc.

Texas Attorney General Ken Paxton sued Amazon.com, Inc. on August 31, 2026, alleging Amazon deceived advertisers by claiming to run second-price auctions while secretly applying hidden surcharges and undisclosed 'soft reserve' prices that pushed winners' costs up by roughly 17% on ordinary days and more than 25% during peak events like Prime Day. The hidden surcharges generated roughly $4.5 billion in additional nationwide revenue in 2024, and more than 18,000 Texas sellers and vendors advertise on the platform. The State brings claims under the Texas Deceptive Trade Practices Act, seeking civil penalties of up to $10,000 per violation, an injunction against inaccurate auction descriptions, and per-auction pricing records for every Texas advertiser; the FTC and a coalition of other states filed a parallel federal action the same day.
