The Federal Trade Commission and 22 state attorneys general filed a lawsuit in Seattle alleging Amazon manipulated ad auction prices to boost profits. The complaint claims that 1.2 million advertisers were duped out of $20 billion between 2018 and 2025.
Why it matters
The suit alleges that Amazon routinely replaced organic auction results with internal bids to raise the price of pay-per-click ads. For operators, this raises concerns regarding the transparency of ad pricing and the potential for platform-controlled auctions to inflate marketing expenses.
The FTC complaint cites $20 billion in alleged advertiser losses against Amazon’s $68 billion in total digital ad revenue last year. Amazon allegedly intervened in auctions to raise prices 70% to 80% of the time, resulting in a 50% cost increase for pay-per-click ads on major shopping days.
The players
Federal Trade Commission
The federal agency charged with protecting consumers and enforcing antitrust laws through administrative and court proceedings.
Amazon
A global e-commerce and cloud computing corporation that operates as a dominant marketplace and digital advertising platform.
The details
According to the 181-page filing, Amazon allegedly overrides auction results by submitting secret bids that raise the price floor for participants. By manipulating these outcomes, the company reportedly inflated pay-per-click costs while replacing competitive market outcomes with higher, platform-set prices. This practice allegedly occurred with significant regularity, targeting millions of businesses dependent on Amazon's advertising ecosystem.
Timeline
2018 marked the beginning of the alleged $20 billion in advertiser losses.
2019 was the start of the period for the systematic overcharging of customers.
October 2, 2026, was the date the FTC filed the lawsuit in federal court.
2025 served as the endpoint for the seven-year period of alleged advertiser losses.
Market Landscape
This lawsuit signals an escalation in federal oversight of digital advertising auctions, following a pattern set by the $2.5 billion Prime subscription settlement last year. It marks a significant shift as regulators move from addressing consumer-facing billing to auditing internal platform auction mechanics.
Operators currently spending on Amazon ads should review historical campaign data for anomalies around peak shopping periods. If marketing budgets were impacted by unexplained cost spikes, consult with your legal counsel regarding potential participation in class actions or recovery processes.
The takeaway
The lawsuit suggests that platform-controlled advertising auctions may be inherently rigged against the advertiser to favor corporate profit margins. Businesses should consider diversifying their ad spend across multiple platforms to mitigate the risk of platform-side auction manipulation.
