FTC and 22 States Sue Amazon Over Alleged $20 Billion Ad Auction Scheme

How Did Amazon Allegedly Manipulate Its Ad Auctions?

The Federal Trade Commission, joined by attorneys general from 22 states, filed a lawsuit against Amazon on Tuesday, accusing the company of manipulating its advertising auction system to overcharge advertisers by more than $20 billion. The legal action alleges that Amazon made unilateral changes to how ads are ranked and priced on its platform, favoring its own products and increasing costs for third-party sellers without transparency. The suit claims these adjustments, implemented over several years, violated antitrust laws by harming competition and inflating advertising expenses across the marketplace.

Amazon’s advertising business has grown rapidly, becoming a major revenue driver as the company expanded beyond retail into digital ads. According to the FTC, the alleged scheme involved altering auction mechanics in ways that were not disclosed to advertisers, effectively raising the price they paid for ad placements. The agency argues that these changes allowed Amazon to extract additional revenue while undermining fair competition, particularly affecting small and medium-sized businesses that rely on the platform to reach customers. Internal documents cited in the complaint suggest Amazon executives were aware of the financial impact of these adjustments.

What Are the Potential Consequences for Amazon and Advertisers?

The FTC claims Amazon modified its ad ranking algorithm to prioritize its own first-party products and favored advertisers, even when their bids were lower than competitors’. This practice, known as „bid shading” or „auction manipulation,” allegedly caused advertisers to pay more than necessary to maintain visibility. The agency says these changes were made without informing users of the platform, violating principles of fair and open competition. By controlling both the marketplace and the advertising system, Amazon allegedly created a conflict of interest that allowed it to favor its own interests over those of independent sellers.

If the court finds Amazon liable, the company could face significant financial penalties and be required to change how its advertising auctions operate. The FTC is seeking injunctive relief to stop the alleged practices and restitution for affected advertisers. A ruling against Amazon could also prompt increased scrutiny of other tech giants that operate both marketplaces and ad platforms. For advertisers, especially small businesses, a favorable outcome might mean lower ad costs and greater transparency in how placements are determined moving forward.

What specific changes did Amazon make to its ad auctions? The FTC alleges Amazon altered its auction algorithm to favor its own products and certain advertisers, increasing costs for others without disclosure, which led to overcharging by more than $20 billion.
