FTC + 22 states sue Amazon over alleged secret Sponsored Ads surcharge (31 Aug 2026)
On 31 August 2026 the FTC and 22 states filed suit against Amazon.com, Inc. in the Western District of Washington (2:26-cv-03097), alleging that since about 2019 Amazon secretly inflated Sponsored Products, Sponsored Brands, and Sponsored Display auction prices with undisclosed “soft reserve” surcharges while telling advertisers it ran generalized second-price auctions—allegedly extracting tens of billions from ~1.2M advertisers. These are complaint allegations; Amazon’s About Amazon response calls the suit misguided and disputes advertiser and consumer harm.

FTC + 22 states sue Amazon over alleged secret Sponsored Ads surcharge (31 Aug 2026)
On 31 August 2026, the Federal Trade Commission and 22 state attorneys general filed a federal lawsuit against Amazon.com, Inc. alleging that Amazon secretly inflated prices in its Sponsored Ads search advertising auctions for years while representing that it ran competitive generalized second-price (GSP) auctions. ShopperCove is not a party to the case, has not subpoenaed Amazon Ads data, and has not contacted FTC or Amazon counsel for this article. The facts below come from the FTC’s 31 August 2026 press release, the complaint PDF (W.D. Wash. 2:26-cv-03097, filed 08/31/26), the CourtListener docket, and Amazon’s public response, all read on 5 October 2026.
Everything attributed to the complaint is an allegation unless a court later rules otherwise. Amazon disputes the claims. This post is not the same story as ShopperCove’s live Amazon Prime FTC refund coverage (subscription cancellation / refund program). This is an advertising-auction suit aimed at brands and sellers who buy Sponsored Ads—not a CPSC recall and not a settled redress program with a claim form. This is not legal advice.

Who sued whom, and where
From the press release and complaint:
- Plaintiffs: FTC plus attorneys general / state enforcers for Alaska, Arizona, California, Colorado, Florida, Idaho, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maryland, Nebraska, New Jersey, New York, North Carolina, Oklahoma, Pennsylvania, Rhode Island, South Carolina, Vermont, and Washington (press lists these 22 states joining the FTC).
- Defendant: Amazon.com, Inc.
- Court: U.S. District Court for the Western District of Washington, case 2:26-cv-03097 (docket shows complaint entered 31 Aug 2026).
- Commission vote authorizing staff to file: 2–0 (per press).
- Relief sought (complaint prayer / press framing): permanent injunction, monetary judgment / civil penalties and other equitable relief under the FTC Act and enumerated state consumer-protection statutes—not a completed settlement.
What the FTC and states allege
High-level theories from the press release and complaint introduction (again: allegations):
- Amazon told advertisers for years that Sponsored Ads placements (especially Sponsored Products, plus Sponsored Brands and Sponsored Display) were priced via second-price / GSP auctions—winner pays roughly one cent more than needed to beat the next-ranked bid—not a first-price “pay your own bid” auction.
- Beginning around late 2018 / 2019, Amazon allegedly began overriding GSP results with higher prices using undisclosed “soft reserve” / “proxy 2nd price” mechanisms that internal documents (as quoted in the complaint) called a surcharge hidden in auction pricing.
- The complaint alleges roughly 1.2 million advertising customers were affected, including over 500,000 small- and medium-sized businesses, and that the scheme likely extracted over $20 billion / “tens of billions” from unwitting advertisers.
- For Sponsored Products, the complaint alleges advertisers paid their own winning bid an increasing share of the time (press: rising toward roughly 80% by 2024), effectively converting many nominally second-price auctions into first-price outcomes while advertisers still bid as if GSP rules applied.
- Plaintiffs allege Amazon concealed the change—including misleading answers when advertisers asked about auction format—because disclosure would cause bid shading / lower spend (“irrevocable damage to advertiser trust” language appears in complaint quotes of internal docs).
- Press / complaint theory of consumer impact: higher ad costs passed through into higher retail prices for shoppers. That pass-through theory is contested (see Amazon’s response below).
What Amazon says in response
Amazon’s About Amazon response calls the lawsuit “misguided” and says Amazon strongly disagrees. Among Amazon’s public points (company statements, not court findings):
- Advertisers optimize from real-world performance, not auction-mechanics descriptions; Amazon estimates relevancy-weighted ranking saved advertisers over $8 billion (2021–2025) versus bid-only selection.
- For Sponsored Products search ads, Amazon says average cost-per-click remained flat inflation-adjusted 2019–2024, conversion rates rose, and average winning bids fell sharply as relevancy weighting increased.
- Amazon says advertisers never pay more than their bid; it describes hard and soft reserve concepts as industry-common valuation tools and says it updated Help / guidance on reserves.
- Amazon argues the complaint cites little evidence of consumer price increases, notes proposed redress would go to advertisers not shoppers, and says it looks forward to making its case in court.
Treat both sides as advocacy until adjudication.

Do not merge claim instructions from the Prime article into this auction case.
What sellers and advertisers can do practically (non-legal)
- Read the FTC press and skim the complaint PDF; follow the docket for answers / motions.
- Review Amazon Ads Help language on auctions / reserve pricing yourself; compare CPC / RoAS trends in your own console or Marketing Stream exports—ShopperCove is not auditing your account.
- Ignore cold DMs promising “Amazon ads FTC refund portals” unless an official FTC redress page for this case appears later. Report fraud at ReportFraud.ftc.gov.
- This article does not tell you how to bid, shade bids, or litigate.
Bottom line
As of 5 October 2026, the FTC and 22 states have an active complaint against Amazon (2:26-cv-03097, filed 31 Aug 2026) alleging years of undisclosed Sponsored Ads soft-reserve surcharges while Amazon marketed GSP auctions—allegations only. Amazon’s public response denies advertiser and consumer harm and will litigate. Distinct from the Prime refund post. No affiliate.
