1. Top Story of the Day

FTC and 22 states sue Amazon over an undisclosed ad auction surcharge

What happened: On August 31, 2026, the Federal Trade Commission and 22 state attorneys general sued Amazon in the U.S. District Court for the Western District of Washington. The complaint alleges that beginning in 2019, Amazon inserted an undisclosed charge into its ad auctions that its own internal documents call a soft reserve price — an invented auction participant and a proxy second price Amazon calculated itself rather than derived from real bidder competition. The FTC says it ran over seven years across Sponsored Products, Sponsored Brands, and display ads, touching more than 1 million brands and sellers, roughly 500,000 of them small and medium-sized businesses. Press coverage puts the total overcharge at $20 billion or more across about 1.2 million advertisers.

Why it matters: The FTC alleges the share of Sponsored Products auctions where the advertiser paid their own winning bid — rather than the lower amount a second-price auction implies — rose from 30-40% in 2021, to 70% in 2022, to approximately 80% in 2024. If that holds up, a nominally second-price auction has behaved close to a first-price auction since 2022, which changes what your bid buys. Amazon disputes this: average cost per click stayed flat from 2019 to 2024 while sales from those clicks rose, soft reserve prices are common industry-wide, and the FTC cherry-picked outdated internal documents. Amazon shares fell about 3% on the filing.

Expert take: Treat this as a measurement problem, not a windfall. Litigation this size resolves over years and no refund mechanism exists today. What is actionable is the reporting gap it exposes — blended ACoS hides which ASINs absorbed the charge, because the alleged effect lands per auction, not per account.

Action items:

Read ad cost per unit sold at product level for Sponsored Products and Sponsored Brands rather than blended account ACoS, and archive the export.
Retain your bid and placement reports as far back as your account allows — the alleged conduct spans 2019 to 2024.
Do not restructure campaigns on an unproven complaint. Amazon's defense — flat CPC alongside rising sales per click — is testable against your own account.

2. Amazon Policy & Program Updates

International & Pan-EU FBA

From September 3, 2026 — tomorrow — every Pan-European FBA product, new and existing, must carry an active offer on Amazon.nl on top of the existing France, Germany, Italy and Spain requirements. A matching Amazon.com.be requirement follows February 26, 2027 at enrollment. Products with no existing detail page on either marketplace are exempt, and sellers need not create those pages. Reporting indicates non-compliant ASINs lose Pan-EU eligibility and revert to cross-border fulfillment, which carries a different fee structure. (ecommerceNews EU; ChannelX)

If you run Pan-EU, this is today's only genuinely urgent item. Audit your enrolled ASINs against your Amazon.nl offers before the deadline — anything that falls out converts silently, and you learn about it from the fee line, not a notification.

FBA & Fulfillment

Holiday peak fulfillment fees run October 15, 2026 through January 14, 2027 across FBA, Remote Fulfillment with FBA, MCF, and Buy with Prime. The per-unit increase averages $0.32 over non-peak rates, unchanged from last year, with the 3.5% fuel and logistics surcharge on top. No new deal eligibility requirements this year. (EcomCrew)

2A. False Alarms & Noise Filter

Monitoring — "Prime Big Deal Days 2026 will run October 7-8."

Why it matters if true: Inventory arrival and ad-budget pacing key off shopping dates, not submission deadlines.

What we actually know: Multiple trade outlets list October 7-8, but as of mid-August 2026 Amazon had not announced official U.S. dates. The figure is inferred from prior years — October 10-11 in 2023, October 8-9 in 2024, October 7-8 in 2025, each a Tuesday-Wednesday. Plan against Amazon's published inventory deadlines, which are confirmed. (TODAY)

3. Marketplace Opportunities & Threats

The BFCM deal-fee discount closes September 5

Setup: The early-submission discount on Black Friday Week and Cyber Monday deals expires September 5, 2026. Amazon takes $50 off the upfront promotion fee per deal submitted by that date; the standard fee is $100 upfront plus a variable 1.5% of promotional sales, capped at $5,000.

Math: The discount halves the upfront fee, $100 to $50 per deal. Ten deals submitted by September 5 cost $500 instead of $1,000; twenty saves $1,000. The variable 1.5% is unaffected, so the saving costs nothing in deal terms.

Who this fits: Any seller already planning BFCM submissions — the window runs to October 20, so this is only about doing the work now rather than in seven weeks.

Execute: Submit your intended BFCM deal list in Seller Central before September 5; terms can be refined later. (EcomCrew)

4. Advertising & PPC Insights

Published 2026 benchmarks put the platform-average Sponsored Products cost per click at about $1.18, ranging $0.38 to $1.45 by category. ACoS runs roughly 32-34%, most accounts between 25% and 40%, median spanning 19% in Books to 42% in Clothing. Treat these as a category sanity check only — an account above its median may simply sit in a competitive niche, and a benchmark gap is not evidence of the conduct the FTC alleges. (Autron)

5. International & Cross-Border

France's levy on ultra-fast fashion took effect September 1, 2026. Per-item fees this year are €0.50 on underwear, €2 on a T-shirt, €9 on jeans and €12 on a jacket, scaling toward €19.50 per item by 2030 and capped at 50% of pre-tax price. Qualification turns on two criteria — the volume of clothing the seller places on the market, and repair cost relative to purchase price. The measure follows June legislation and targets Shein, Temu and AliExpress. Apparel sellers on Amazon.fr should read it as a price floor moving under those competitors rather than a cost landing on them; the volume criterion determines scope. (The Local; France 24)
