FTC Plans to File Advertising Lawsuit Against Amazon, Potentially Facing Billions in Fines
Claire Weston
The FTC has drafted a complaint alleging Amazon misled advertisers on ad pricing, with multiple states joining to impose per-day penalties that could total billions of dollars — the agency's most direct strike yet at Amazon's fastest-growing revenue engine.
What exactly is the FTC investigating?
The FTC's consumer-protection division is leading the probe. The core allegation: Amazon misled advertisers on how its search-ad pricing works.
The focus is "reserve pricing" — a minimum bid advertisers must meet before they can compete for an ad slot. The FTC says Amazon failed to adequately disclose this mechanism.
This means → advertisers may have paid more than they realized, generating non-transparent profit for Amazon's ad platform.
How can fines reach "billions"?
The FTC itself faces statutory caps on monetary penalties, but multiple state attorneys general have joined the case, bypassing that limit.
State consumer-protection laws allow per-day fines of tens of thousands of dollars.
In plain terms = Amazon's platform serves a massive volume of ads daily. Multiply per-day fines by that volume, and the cumulative total scales into billions.
How important is advertising to Amazon?
Full-year 2025 ad revenue reached $68.6 billion, making it one of Amazon's fastest-growing businesses.
The segment spans on-site search ads, video ads, and off-site display ads.
This reflects a structural shift: advertising is no longer a side business — it stands alongside e-commerce and cloud as a core profit engine. A regulatory hit here strikes at the company's highest-growth segment.
How might this end?
The FTC could resolve the probe as early as this summer, either by filing suit or reaching a settlement.
Any final decision requires a vote by the FTC's two Republican commissioners — Chair Andrew Ferguson and Commissioner Mark Meador — so the outcome remains uncertain.
Precedent: last autumn Amazon paid $2.5 billion to settle a Prime-subscription consumer-protection case; a separate antitrust suit alleging Amazon forced brands to raise prices on rival platforms goes to trial early next year. This means → Amazon is fighting on multiple regulatory fronts simultaneously, and the ad case is simply the newest one.
