On September 1, the Federal Trade Commission and a bipartisan coalition of 22 state attorneys general filed suit against Amazon in the U.S. District Court for the Western District of Washington, accusing the company of secretly manipulating its digital advertising auctions to overcharge roughly 1.2 million businesses by more than $20 billion since 2019. It is one of the largest advertiser-facing antitrust actions ever brought against a single platform, and it lands on a company that has spent the past two decades building its retail media business into the third-largest digital advertising platform in the world, trailing only Google and Meta.
The mechanics of the allegation matter more than the headline number. According to the FTC’s complaint, Amazon’s Sponsored Products, Sponsored Brands, and Display Ads auctions were marketed to advertisers as standard second-price auctions — the industry-normal model where the winning bidder pays just one cent more than the next-highest bid, not their own maximum bid. That structure is what encourages advertisers to bid aggressively and honestly: bid your true maximum, and you’ll only ever pay what the market actually demanded. The complaint alleges Amazon quietly broke that promise, introducing undisclosed mechanisms — including what regulators describe as a “soft reserve price” — that pushed the winning price advertisers actually paid above what a genuine second-price auction would have produced, without disclosing the change to the businesses bidding.
An Allegation, Not a Verdict
None of this has been proven in court. Amazon disputes the FTC’s characterization entirely, telling reporters that advertisers using its platform have seen improved performance and real value for their spend, and that the company’s ad tools are designed to help businesses of every size compete effectively. The FTC and the 22 state attorneys general who joined the suit are seeking civil penalties, restitution for affected advertisers, disgorgement of profits Amazon is alleged to have earned from the scheme, and a permanent injunction forcing changes to how the company runs its ad auctions going forward. Whatever the outcome, the case will likely take years to resolve, and Amazon has both the legal resources and the incentive to fight it hard — its advertising business now generates tens of billions of dollars a year, almost all of it in the high-margin territory that keeps Amazon’s overall retail operation profitable even when its low-margin logistics and fulfillment businesses aren’t.
What makes this case different from the antitrust actions Big Tech has faced over the past several years — most of which have centered on platform gatekeeping, self-preferencing, or acquisition strategy — is that it’s fundamentally about trust in a pricing mechanism. Second-price auctions are the plumbing underneath most of digital advertising, from Google Search to programmatic display networks to, now allegedly, Amazon’s own marketplace. If regulators can establish that Amazon quietly departed from the model it told advertisers it was using, the case becomes less about market power in the abstract and more about a specific, provable claim: that a company said X and did Y, and pocketed the difference at scale for years.
The Advertisers Caught in the Middle
The 1.2 million businesses named in the FTC’s estimate are not primarily other Big Tech firms — they’re the sellers, brands, and small-to-midsize merchants who rely on Sponsored Products placement just to be visible in Amazon’s search results at all. For many of them, advertising on Amazon isn’t optional marketing spend; it’s closer to rent for shelf space in the store that increasingly is the store. A pricing mechanism that quietly extracts more from that group than disclosed terms promised has a direct, compounding effect on margins for exactly the kind of small e-commerce operators who have the least leverage to push back or walk away, since Amazon’s search visibility is often the only realistic path to discovery for a product competing against thousands of similar listings.
What This Means for Philippine Founders
Filipino sellers and brands running Amazon storefronts — a real and growing group, particularly in categories like beauty, home goods, and specialty food that export well from the Philippines — are part of the advertiser pool this case is about, even if most of them are too small individually to have noticed a few extra cents per click compounding over years. The more immediate lesson is structural: any startup or brand whose customer acquisition depends on a single platform’s auction-based ad system — Amazon, Meta, Google, TikTok, Lazada, Shopee — is trusting that platform’s own disclosed pricing model, with essentially no way to independently verify it’s being honored at the scale a single seller can observe. This case is a reminder to build acquisition channels that don’t depend entirely on one platform’s auction integrity, and to watch how this suit resolves: a real financial penalty or forced auction redesign at Amazon would likely pressure every other ad-auction platform, including the ones Philippine sellers and marketplaces already use daily, to get ahead of similar scrutiny rather than wait for their own version of this lawsuit.
