The FTC Is Coming for Amazon's Advertising Empire
In what could become one of the most consequential antitrust actions in the history of digital commerce, the Federal Trade Commission (FTC) is reportedly preparing a major legal challenge aimed squarely at Amazon's advertising business. With Amazon pulling in an eye-popping $68 billion in total ad revenue in 2025, the stakes could not be higher — not just for the tech giant itself, but for every brand, seller, and consumer who interacts with Amazon's sprawling digital marketplace.
If the FTC moves forward, this case could fundamentally reshape how advertising works inside the world's largest e-commerce ecosystem. Here's everything you need to know about what's happening, why it matters, and what could come next.
Amazon's Advertising Business: A $68 Billion Juggernaut
To understand why the FTC is paying attention, you first need to appreciate just how dominant Amazon's advertising operation has become. Amazon's ad revenue reached $68 billion in 2025, cementing its position as the third-largest digital advertising platform in the United States, trailing only Google and Meta. What began as a relatively modest "sponsored products" feature has grown into a full-fledged advertising ecosystem that now rivals the legacy digital ad giants in scale, sophistication, and influence.
Amazon's ad platform is uniquely powerful because it sits at the intersection of intent and action. When a user searches for a product on Amazon, they are not casually browsing — they are ready to buy. This purchase-ready audience is extraordinarily valuable to advertisers, which is why brands and third-party sellers alike have poured billions of dollars into Amazon's sponsored listings, display ads, video placements, and streaming ad products.
But this dominance is precisely what has drawn the attention of federal regulators.
What the FTC's Case May Focus On
While the full scope of any forthcoming complaint has not been publicly confirmed, regulatory observers and industry insiders have pointed to several areas where the FTC may argue that Amazon has used its market position in ways that stifle competition and harm both sellers and consumers.
Forced Advertising to Gain Visibility
One of the most significant concerns involves the way Amazon's algorithm treats paid versus organic listings. Third-party sellers operating on the platform have long complained that organic search visibility has declined steadily over the years, effectively forcing sellers to purchase sponsored placements just to appear in front of shoppers. Critics argue this creates a self-reinforcing pay-to-play system where Amazon profits twice — once as the marketplace facilitating a sale, and again as the advertising platform charging sellers for the visibility needed to make that sale possible.
Data Advantages and Competitive Conflicts
Amazon also operates its own private-label brands, which compete directly with third-party sellers on the same platform. Regulators have previously expressed concern that Amazon may use proprietary sales and behavioral data — data collected from those very third-party sellers — to inform the development and promotion of its own competing products. If advertising data is also being leveraged in this way, the FTC may argue that Amazon is using its dual role as both marketplace operator and advertiser to gain an unfair competitive advantage.
Auction Transparency and Pricing Practices
Amazon's ad auctions, like those of most digital platforms, operate largely as black boxes. Sellers bid for placement but have limited insight into how bids are ranked, how ad relevance scores are calculated, or whether Amazon's own products receive preferential treatment in the auction process. A lack of transparency in these systems could form another pillar of a potential FTC case.
Why This Moment Matters for the Broader Ad Industry
An FTC action against Amazon's advertising practices would not occur in isolation. It would land in the middle of a much broader regulatory reckoning with Big Tech's grip on digital advertising. The Department of Justice has already pursued antitrust action against Google's advertising technology business. Meta has faced its own regulatory scrutiny in Europe and at home. Amazon becoming the next major target would signal that federal regulators view the concentration of advertising power among a handful of tech platforms as a systemic issue, not a series of isolated concerns.
For advertisers — particularly small and mid-sized brands that rely heavily on Amazon's platform to reach customers — the outcome of any legal action could have real and immediate consequences. If the FTC succeeds in forcing structural changes to how Amazon sells or manages its ad inventory, brands may find new opportunities for fairer competition, more transparent pricing, and potentially lower costs. On the other hand, any major disruption to the platform could introduce short-term uncertainty for sellers who have built their entire go-to-market strategy around Amazon advertising.
What Brands and Sellers Should Do Now
Regardless of how any legal proceedings ultimately unfold, this regulatory moment serves as a timely reminder for brands of all sizes to avoid over-reliance on any single advertising platform. Diversifying ad spend across channels — including Google Shopping, Meta, TikTok, and emerging retail media networks — is sound strategy under any circumstances, and becomes even more important when a platform faces the prospect of significant structural change.
Brands should also stay informed about the FTC's proceedings and consider engaging with industry groups that may participate in any public comment processes. The rules governing digital advertising are evolving rapidly, and businesses that understand the regulatory landscape will be better positioned to adapt.
The Bottom Line
Amazon's $68 billion advertising business has made it an indispensable partner for millions of brands — and an increasingly attractive target for federal regulators. A major FTC legal action could reshape the rules of engagement for the entire digital advertising industry. Whether you are a brand manager, a third-party seller, or simply a consumer who has noticed more and more sponsored content cluttering your Amazon search results, the outcome of this looming legal battle will likely affect you in ways both visible and invisible. Now is the time to pay close attention.
