Amazon on September 14, 2026, set its autumn Prime Big Deal Days for October 6 and 7, a 48-hour members-only sale covering more than 35 product categories in 22 countries, with new limited-time deals released three times a day and its merged AI assistant, Alexa for Shopping, positioned as the main tool for tracking prices during the event.

In Short

Amazon picked October 6 and 7 for its second big Prime-only sale of the year, and it will run in 22 countries. Brands and sellers who sell on Amazon had to send in their discounts and ship their stock before Amazon even said which days the sale would be. This year shoppers can also ask Amazon's AI assistant to watch prices and buy automatically once a product gets cheap enough, which changes how and when people end up buying.

What Amazon published

The announcement appeared on Amazon's corporate news site under the byline of Jacquelyn Smith. According to Amazon, the event opens at 12:01 a.m. PDT on October 6 and runs for 48 hours, giving Prime members access to what the company describes as millions of deals on top brands, seasonal products and everyday essentials. The company frames the sale around Halloween, autumn hosting, home decoration, beauty and early holiday gifting, and states that the discounts sit on top of its everyday low prices.

Carmen Nestares, vice president of North America Marketing and Prime Tech, supplied the only named statement in the release. "Once fall arrives, there's so much to get ready for - the hosting, the decorating, the holiday gifting - and Prime Big Deal Days makes it easy to check it all off while saving," Nestares said.

Prime Big Deal Days is the younger of Amazon's two Prime-exclusive tentpoles. The company introduced it as a second annual members-only sales event in October 2022, and the 2025 edition ran on October 7 and 8. The format has not grown the way its summer sibling has. Prime Day was stretched to four days for the first time in 2025, while the October event remains a two-day affair in 2026.

The deal-drop schedule

The structural change this year sits in the release cadence. According to Amazon, new offers under the Today's Big Deals banner will appear three times a day - at midnight, 8 a.m. and 1 p.m. PDT - throughout the 48 hours. That produces six scheduled drops across the event. Brands named in the announcement include Shark, Princess Polly and Soundcore by ANKER, alongside what Amazon calls first-time deals from brands new to the store. The company says these deals last only while supplies last.

When Amazon first used the Today's Big Deals label for Prime Day 2025, the themed drops went live once a day at midnight PDT. Three daily windows compress more releases into fewer hours. For a brand with a lightning-style offer, the practical question is which of the six slots its deal lands in, since an 8 a.m. Pacific release reaches European shoppers in the late afternoon and East Coast shoppers before lunch.

The release itemises a set of price points that show where Amazon wants attention to go:

  • Halloween: a Top 100+ Deals list, costumes and accessories from $5 and candy under $10.
  • Hosting and home: charcuterie boards, slow cookers, blankets, candles and pillows from brands including UGG, NEST New York and Barefoot Dreams.
  • Groceries: Dietz and Watson salami at $3, Sabra Hummus, Amazon Kitchen Pico de Gallo and cherry tomatoes at $1 each, and avocados at $0.33, with savings of up to 75% on select grocery items delivered same day.
  • Amazon Haul: seasonal decor and fashion from $1, with up to 50% off game-day essentials.

Grocery sits unusually high in the announcement for an event historically dominated by electronics and devices. It fits a pattern. Amazon's own reporting showed fresh groceries holding six of the top 20 bestseller positions on Amazon.com in late August. The release adds that Prime members receive free grocery delivery on orders over $25 in most areas.

Two further items target the gifting calendar. Amazon says its Holiday Shop carries more Amazon-exclusive items than in any previous year, though it gives no count. And for the first time, FAO Schwarz, the toy brand, has a dedicated storefront on Amazon, placed alongside the company's annual Top 100+ Toys List.

Alexa for Shopping as the event's price engine

The largest block of the announcement is given to Alexa for Shopping, and it is where the implications for advertisers concentrate. Amazon merged Rufus and Alexa+ into a single assistant on May 13, 2026, making it available to all US customers on the Shopping app, the website and Echo Show devices. Prime Big Deal Days is the first October event in which that combined assistant is live.

According to Amazon, the assistant can do four things during the sale:

  1. Create Deal Alerts for product types described in natural language, with daily updates when matching deals appear, and set a target price on a specific item that triggers a notification when it is reached.
  2. Run Auto-Buy, which purchases an item automatically once it hits the shopper's target price.
  3. Show Price History covering up to 365 days on what Amazon calls hundreds of millions of products, either through a link on product pages or by asking the assistant.
  4. Check saved lists for items currently on deal, and track new product releases from named brands "across Amazon and the web".

None of these capabilities is new to the September announcement. The 365-day price history was extended to over 50 million customers in the US, UK, Canada and India on May 1, 2026, before the merger. The release describes them as "new ways to discover savings," a framing that applies to the event rather than the features.

What changes is the setting. A price history visible for a full year makes an inflated reference price easier for a shopper to spot, which shifts the burden onto the depth of the actual discount. Auto-Buy is more consequential still. A purchase triggered by a price threshold does not require the shopper to scroll through a search results page at the moment of conversion, which means the sponsored placements on that page do no work for that transaction.

That sits on top of a compression already measured in the assistant's conversational mode. Research by Workflow Labs found that Rufus narrowed effective product discovery from roughly 50 search results to about five named products per response. Amazon has monetised part of that surface: its AI shopping prompts moved from free beta to billable status on March 25, 2026. Across a two-day event where deal badges already carry much of the visibility, an increasing share of the decision is taking place in places where the traditional keyword auction has less reach.

What the calendar asked of sellers

For third-party merchants, the date arrived late in the planning cycle. Amazon's Holiday 2026 seller calendar, posted to the Seller Central forums in early July, set binding deadlines for an October event it had not yet dated, stating only that the sale would return at the same time as last year. Sellers on that thread worked out from the 2025 pattern that the event would most likely fall on October 6 and 7. Amazon did not confirm the reading at the time. It has now proved correct.

The sequence is worth setting out in full. Deal submission for Prime Big Deal Days opened on July 8, with fees held flat from Prime Day. The early-submission reduction on the upfront promotion fee expired on August 5, and the submission window itself closed on September 8. Amazon published the dates on September 14 - six days after that window shut. The controlling inbound inventory deadline for Fulfillment by Amazon shipments using the Amazon-optimised shipment splits option fell on September 16, two days after the announcement.

In other words, every commitment a seller could make for this event - deal type, discount depth, promotion fee, stock volume - had to be made before Amazon stated when it would run. A year earlier, Amazon confirmed the 2025 dates on September 16, the same calendar day as this year's inventory cutoff. The 2026 announcement came two days earlier than that.

The confirmed dates also set the length of the replenishment gap before the November trading block. Black Friday falls on November 27, 2026. An October 6 start leaves roughly seven weeks to Black Friday, against six if the event had started a week later.

A separate change added a second audience to the same event. On August 31, Amazon opened a business-only deal type to third-party sellers, with minimum discounts of 15% during what it calls High Velocity Events, a category it defines by example as Prime Big Deal Days, Black Friday and Cyber Monday. Amazon says those deals can reach over 11 million registered business organisations.

Geography: 22 markets, four fewer than June

According to Amazon, Prime members in 22 countries can shop the event: Australia, Austria, Belgium, Brazil, Canada, Colombia, France, Germany, Ireland, Italy, Japan, Luxembourg, Mexico, the Netherlands, Poland, Portugal, Singapore, Spain, Sweden, Turkey, the United States and the United Kingdom. The company adds that dates may vary by country, without specifying which markets differ.

That list is longer than the 19 countries covered when Amazon confirmed the 2024 event. It is shorter than Prime Day. The June 2026 event spanned 26 countries, including Egypt, Saudi Arabia, the United Arab Emirates and India, none of which appears on the October list. Colombia, which was part of the Prime Day market set, is included.

The caveat about varying dates matters most for European advertisers. Germany, France, Italy, Spain and the United Kingdom each run their own Amazon marketplace, auction and deal calendar. An event that the US release dates to October 6 and 7 may not align exactly in every one of them, and the announcement offers no per-market schedule.

Delivery claims and membership pricing

The release restates Amazon's delivery tiers as part of the pitch for the event. Prime Air drones can deliver in as little as 30 minutes in select suburban areas, according to Amazon. The company recently said it would bring Prime Air to nearly 500 US cities and towns by the end of 2026, from 11 current sites. Amazon Now, the 30-minute service for groceries and essentials, operates across dozens of US cities; it started in May at $3.99 per order for Prime members. More than 90,000 items are available with one-hour and three-hour delivery through the Same-Day network, and free Same-Day or Next-Day Delivery reaches more than 10,000 US cities and towns, according to the company.

Membership prices are unchanged from those Amazon has quoted in previous event announcements. Prime costs $14.99 per month or $139 per year, with a 30-day free trial for eligible customers. Prime for Young Adults, open to people aged 18 to 24 and to college students, offers a six-month $0 trial followed by $7.49 per month or $69 per year. Prime Access, for qualifying recipients of government assistance and income-verified customers, costs $6.99 per month after a 30-day trial.

Amazon describes both discounted options as providing the same benefits "at only 50% of the cost." The arithmetic holds closely for Prime for Young Adults: $7.49 is 49.97% of $14.99, and $69 is 49.6% of $139. Prime Access, at $6.99, is closer to 47% of the standard monthly fee. The difference is small, but the statement is not precise for both tiers.

During the event, Prime for Young Adults members and higher education students can also stack 5% cash back on eligible deals in beauty, apparel, PCs, electronics and personal care. Amazon ran a similar 5% cash back offer on dorm purchasesover the summer.

Members can already shop early deals on Amazon devices, Kindle, Amazon Haul and Amazon Music, according to the company.

Why the October event matters to advertisers

For brands and agencies, Prime Big Deal Days is primarily an advertising event. Amazon operates one of the largest retail media network businesses, and its second-quarter 2026 results put advertising services revenue at $19.8 billion, up 26% year over year, with Sponsored Products named as the largest contributor. Tentpole events concentrate that demand into short windows of onsite inventory.

The June Prime Day offered a warning about how such events are changing. CommerceIQ measured US ad spend down 8.8% and unit conversion up 17.1% during the four-day event, with product page traffic falling 10.3% year over year. Fewer visits, more purchases per visit. CommerceIQ attributed part of the conversion gain to Alexa for Shopping. If the October event repeats that pattern - with Auto-Buy and price alerts now promoted directly in the event announcement - brands could find that less of the event's revenue flows through the pages on which they bid.

The pricing of those bids is now contested in court. The Federal Trade Commission and 22 states sued Amazon on August 31 over alleged hidden advertising surcharges. According to the complaint, Amazon raised its surcharge ceilings around what it internally calls high velocity events, a list that explicitly includes Prime Big Deal Days. Those are allegations, and Amazon has not been found liable. But the October event will be the first of its kind run while the claim is live, and cost-per-click movements during those 48 hours are likely to be watched more closely than usual by advertisers and their agencies.

The event also closes a crowded late-summer calendar. After moving Prime Day into June, Amazon filled the gap with Labor Day Deals in the US and Second Chance Deal Days across European markets from September 1, where used and returned items were discounted by up to 50%. Each of these events draws on the same reference prices and the same shopper attention. Prime Big Deal Days arrives as the fourth discount window since late August, with Black Friday about seven weeks behind it.

The release contains no targets and no forecasts. Amazon does not state how many deals will run, how many sellers are participating, or how the 2025 event performed. Results, if Amazon publishes any, would normally follow shortly after October 7.

Timeline
