Prime Big Deal Days Is October 6-7. Here Is What Brands Need to Know Before the Event Starts.

Amazon confirmed the dates on September 14: Prime Big Deal Days returns October 6-7, 2026 — two days of exclusive deals for Prime members kicking off the fall and holiday shopping season. The event runs across 22 countries, with new deal drops three times daily at midnight, 8 a.m., and 1 p.m. PDT. For brands selling on Amazon, the operational window is already closing. The Deal Submission Deadline Has Passed — But Not Everything Is Closed The extended deal sourcing deadline of September 22 has passed for Best Deals and Lightning Deals. If those are not already submitted and approved, they will not run during the event. What is still available: Prime Exclusive Discounts and Coupons can still be activated closer to the event and remain eligible throughout the window. One pricing detail worth knowing: Prime Big Deal Days promotional prices are excluded from the 30-day and 60-day lookback window used to determine Black Friday Week deal eligibility. You can price aggressively now without affecting your Black Friday Week pricing ceiling. Inventory The FBA inbound cutoff for Prime-badge eligibility was September 9 for EU markets and September 16 for the UK. For US sellers, if inventory is not already at fulfillment centers or in confirmed transit, it will not carry Prime eligibility during the event. If stock is in place, focus now on monitoring levels for your deal ASINs. Running out on day one of a two-day event eliminates day two entirely — and ranking signals from a stockout take weeks to recover. Alexa for Shopping Amazon is positioning Alexa for Shopping as the primary deal navigation tool for this event — shoppers can set deal alerts, check 365-day price history, and enable Auto-Buy at a target price. Listing quality and pricing history are now discovery inputs. A product with thin content or an unfavorable price history is less likely to be surfaced when a shopper asks Alexa for deal recommendations in your category. Advertising Campaigns supporting deal ASINs should already be live. If they are not, launch today — not October 6. Campaigns that start on event day start cold. CPCs will spike during the event — plan budgets based on your expected traffic multiple, not your average weekly spend. Campaigns that exhaust budget on October 6 miss October 7 entirely. Prime Big Deal Days is the opening of a 10-week peak season. Black Friday Week follows, with deal submission closing November 18. October 6 is three weeks away.

Amazon made several changes this week that touch on how ads are billed, who can sell without added insurance risk, and how businesses buy on the platform. The biggest story reframes something most advertisers assumed was true about how Amazon Ads pricing actually works. Below is a rundown of the eight updates worth knowing about. 📌 Contents: Amazon Ads Does Not Use a Second Price Auction Amazon Requires China-Based Sellers to Use Its Insurance Accelerator Program Amazon Ads and ChatGPT Announce Advertising Integration Amazon Business Deals Launches for B2B Sellers Across Ten Marketplaces Account Health Rating Adds Customer Service Metrics Amazon Tests New "Targeting with AI" Setting in Ads Console Amazon Germany Shortens Return Window for Sixteen Categories Amazon May Be Testing "Brand Approved" Labels on Product Pages   1. Amazon Ads Does Not Use a Second Price Auction Advertisers have long assumed Amazon Ads runs a second-price auction: bid your true maximum, and the system charges you only a small amount above the next-highest bidder. That assumption shaped how a lot of agencies and brands set their bids. Amazon's own Seller Assistant tool now describes the system differently, calling it a CPC model rather than a traditional second-price auction, with your cost per click influenced by your bid, placement performance, and automated rules. The timing lines up with the FTC's current look into Amazon's advertising practices, and older seller help documentation that described the second-price framing is no longer easy to find. The practical implication is straightforward: treat your bid as the number you might actually pay, not a safe ceiling protected by a discount mechanic. Review your top spending campaigns and check whether bids were set assuming that protection. In comparable cases, resetting bids to match true conversion rate and margin has kept spend more predictable without hurting placement. Read more here by Ritu Java 2. Amazon Requires China-Based Sellers to Use Its Insurance Accelerator Program Amazon is changing its commercial liability insurance requirements, and the most significant part of the change targets sellers based in Mainland China. Those sellers will now be required to obtain insurance through Amazon's own Insurance Accelerator program rather than arranging coverage independently. Under the new setup, a licensed insurance company vets each business and formally approves or denies the policy. This addresses a gap some sellers exploited in the past, combining foreign ownership structures with weak or fraudulent insurance paperwork to avoid liability if something went wrong with a product. The change adds a layer of real accountability inside the United States that did not consistently exist before. Sellers already operating within Amazon's rules should see little change in day-to-day operations. Competitors who relied on thin insurance coverage to keep costs down should expect closer scrutiny on ownership and documentation in the months ahead. Read more here by Jon Derkits 3. Amazon Ads and ChatGPT Announce Advertising Integration Amazon Ads and ChatGPT confirmed an integration that will let brands place Amazon ads inside ChatGPT's shopping conversations. It is a new upper funnel channel that sits outside Amazon's own properties, and platforms like Pacvue are expected to build targeting and automation rules around it as the integration matures. Several open questions will shape how useful this becomes. Measurement is the biggest one: how a ChatGPT ad impression or click gets attributed to an eventual Amazon purchase is not yet clear, and neither is how spend here interacts with organic visibility inside ChatGPT or Amazon's own AI shopping surfaces. Tools built to track share of voice and revenue impact on the organic side are already emerging. This looks like an early piece of a larger move toward advertising inside AI-assisted shopping, a trend likely to keep building over the next year or two. Brands running significant Amazon Ads budgets should watch this closely rather than act on it immediately. Read more here by Christian Rich 4. Amazon Business Deals Launches for B2B Sellers Across Ten Marketplaces Amazon Business Deals is now live across ten marketplaces, including the United States, Canada, the United Kingdom, Germany, France, Italy, Spain, Japan, Mexico, and Australia. It gives sellers a discount tool built specifically for registered business buyers, separate from any promotion running on the consumer side. Unlike a standard Lightning Deal or coupon, this one runs entirely off your Business Price rather than your public listing price, and a SKU with no Business Price set cannot be added to a deal at all. Eligibility is also checked against your pricing history rather than today's price: Amazon compares the discount to your Validated Reference Price and your 30 to 60 day non-promotional low, so a discount that looks reasonable on paper can still fail that check. Once a deal is live, committed units act as a soft cap, with Amazon starting to deactivate the deal around 90% sold, though system latency can let a few more orders through after that point. With Labor Day, Prime Big Deal Days, Black Friday, Cyber Monday, and the holiday season all landing in the next four months, this is a good window to set a Business Price and confirm your pricing history supports the discount tier you want. Sellers who move on this now get in front of Amazon's 11 million registered business accounts before the tactic becomes common in their category. Read more here by Vanessa Hung 5. Account Health Rating Adds Customer Service Metrics Amazon now factors customer service directly into Account Health Rating, worth up to 12 points, and the metrics apply only to orders fulfilled by the merchant where the seller handles support directly. The first metric is buyer contact rate, which needs to stay under 0.50%, counting buyers who reach out about quality, fulfillment, or shipping issues divided by items shipped; a change of mind does not count against the seller. The second is response time, which needs to stay under 12 hours across all buyer messages. The third is dissatisfaction rate, based on post-case satisfaction surveys rated 1 or 2 out of 5, which needs to stay under 4.5%. Amazon built this as an upside-only mechanic: weak numbers carry no penalty, but strong numbers should start showing up in the rating. All three metrics are visible in Feedback Manager. Sellers who handle their own FBM support and already respond quickly should check these numbers now, since the rating may already reflect performance they weren't getting credit for before.

Amazon Tests New "Targeting with AI" Setting in Ads Console A new beta setting called Targeting with AI has appeared under account-level Settings in the ads console. Its description says seasonal keywords and product targets get added to eligible campaigns ahead of upcoming seasons, then paused automatically once the season ends, and the only control currently visible is a single checkbox labeled Apply to active campaigns. The idea has real value in theory: Amazon has more seasonal search data than any individual seller or agency, and surfacing relevant terms ahead of Q4 or Prime Day could save research time. The current version is missing the controls that would make it safe to turn on, though. There is no way to choose which campaigns receive new targets, no visibility into what bids or match types get applied, and no indication that campaign budgets increase to cover the added spend. Turning this on for a tightly built campaign risks diluting its structure and pulling budget away from keywords that are already converting. Until Amazon adds campaign-level controls, it is worth watching rather than enabling. Read more here by Mansour Norouzi 7. Amazon Germany Shortens Return Window for Sixteen Categories Amazon Germany reduced the return window from 30 days to 14 days for 16 product categories, effective September 1. Sellers listing in any of those categories need to check their product listings, A+ Content, and customer service scripts for return policy language that still references the old 30-day window. Leaving outdated promises in place is likely to generate customer complaints once shoppers discover the shorter window at the point of return. This is a straightforward compliance task rather than a strategic shift, but it is an easy one to miss if it is not on someone's checklist this month. Sellers active on Amazon Germany should audit affected listings this week. Read more here by Sebastian Joseph 8. Amazon May Be Testing "Brand Approved" Labels on Product Pages A screenshot circulating on LinkedIn shows a product detail page listing a Wilson item, sold by third-party seller RacquetGalaxy, with the words Wilson approved displayed directly beneath the brand name. If Amazon is beginning to publicly label sellers it considers authorized for a brand, that would address a problem that has existed on the platform for years: shoppers have had no reliable way to tell an authorized seller from an unauthorized one just by looking at a listing. Brand owners running authorized reseller programs could see this reduce the advantage unauthorized sellers get from looking identical to legitimate ones. Resellers outside an authorization agreement could see lower conversion on listings that lack the label. This has not been confirmed as a wider rollout, and it may still be an isolated test. Brand owners should check their own listings for a similar label and flag it to their account team if they see one. Read more here by Ephraim Rosenberg That covers the eight Amazon updates worth tracking this week, from a shift in how Amazon Ads actually bills you to new tools for B2B sellers and account health. Some of these need action in the next few days, others are worth watching before they fully roll out. Subscribe to the ANavigator blog to get next week's digest as soon as it is published.
