Prime Big Deal Days 2026 drew $9.86 billion in US online sales, Adobe says

Amazon's Prime Big Deal Days ran on Tuesday 6 and Wednesday 7 October 2026, and Adobe measured $9.86 billion in US online spending across the two days, up 8.5% year over year^1,2. Adobe says the event is leading US retailers to invest in earlier pre-holiday promotions¹, so sellers should test any calendar change before moving their full inventory and budget.

Adobe measured $9.86 billion in US online spending across the 6–7 October event

US online shoppers spent $9.86 billion during Amazon's 6–7 October Prime Big Deal Days, according to Adobe, which saw sales grow 8.5% year over year¹. Digital Commerce 360 reported the figure on 8 October 2026¹. Retail Dive reported on 9 October 2026 that the two-day event helped drive the $9.86 billion for US retailers, citing Adobe data².

Adobe's data covers direct online transactions across more than 1 trillion visits to US retail sites, 100 million SKUs and 18 product categories¹. In 2025, the equivalent event generated $9.09 billion, up 7.3%¹.

The peak discount was 20% off listed price^1,2. Retail Dive reported that the deepest promotional pricing was in computers, televisions, electronics, toys and apparel, and that many shoppers traded up to higher-priced items².

Toys, video games, electronics and personal care all rose sharply against September

Measured against average September 2026 sales, toy sales rose 158% during the event, according to Adobe¹. Video game sales rose 90%, electronics 85% and personal care products 73% over the same baseline¹.

Retail Dive also reported that household cleaning and paper products rose 55%, personal hygiene products 45% and pet food 45%, as shoppers bought essentials².

The four Adobe figures above share one baseline, average September 2026 levels, so they can be compared with each other. They are not a year-over-year comparison¹.

Mobile sales passed half of online sales, and BNPL drove 6% of orders

Mobile sales grew 12.8% year over year to $5.1 billion and made up 52% of all online sales during the event, according to Adobe data reported by Retail Dive². Digital Commerce 360 gave the mobile share as 52.0%¹.

Buy now, pay later (BNPL) accounted for 6% of total online orders over the two days, or $692.3 million, up 4% year over year². Adobe credited BNPL with enabling 6.0% of online orders¹.

Adobe's pre-event forecast was higher than the result

Adobe's forecast, published on 28 September 2026, projected $9.9 billion in online spending for the 6–7 October event, up 9.2% year over year, with discounts set to peak at 19% off listed price³. MediaPost reported the same $9.9 billion forecast in an article dated 5 October 2026³. It said electronics, toys, TVs, apparel and appliance discounts were expected to range from 15% to 19%⁴.

Set against that forecast, the reported result of $9.86 billion was slightly lower, growth of 8.5% was below the forecast 9.2%, and the 20% peak discount was one point above the 19% forecast^1,2,3.

Adobe says the event should lead retailers to start pre-holiday promotions earlier

Adobe said the event had “changed the shape of the holiday shopping season, pushing U.S. retailers to manage promotions and inventory effectively to capture an additional pre-season spike in shopping interest”². Digital Commerce 360 reported that Adobe sees the event leading retailers to invest in earlier pre-holiday promotions than they would otherwise hold¹.

This is Adobe's view of retailer behaviour. The sources reviewed do not show that earlier promotions produced higher sales.

Numerator's data points to pressure on November events

Numerator, a shopper research firm, said that “Earlier holiday shopping could put pressure on November sales events”². More than a third of shoppers completed at least half of their holiday shopping during Prime Big Deal Days². Intent to shop Black Friday fell 4 points and intent to shop Cyber Monday fell 5 points, compared with last year's event².

Taken together, these findings suggest that some spending may be moving earlier. They do not show that total November demand is lower.

Adobe's separate holiday forecast, published on 28 September 2026, expects US online sales of $275.1 billion from 1 November to 31 December 2026, up 6.7% year over year³. Adobe expects Black Friday to grow faster than Cyber Monday, at 9.2% against 6.2%, driven partly by the largest discounts for TVs, apparel and appliances³.

What sellers should do now

Adobe's suggestion is not a reason on its own to move your calendar. The evidence shows where spending went in one event, not what your products will do. We recommend the following steps.

• Compare your own October sales with your September sales by product category. Check whether your products behaved more like the toy and video game gains or the electronics and personal care gains.
• Confirm that early promotion stock is funded and in place before you commit to a new calendar date.
• Test an earlier promotion on a limited set of products, and compare results with products you did not promote early. Do not move the whole range at once.
• Track November conversion rates and advertising costs against your own figures from last year. Numerator's intent data points to possible pressure on Black Friday and Cyber Monday².
• If you ship during the season, check carrier surcharge dates before you increase inventory in transit. Our peak season 2026 surcharge comparison covers them.

What is not yet known

Adobe has not been shown to link its earlier-promotion recommendation to a measured change in sales timing, and the sources do not show whether sellers who moved promotions earlier gained sales. It is also not yet known whether Numerator's lower intent figures for Black Friday and Cyber Monday will show up in November results, or whether the 6–7 October event moved some spending forward from November². The reported figures come from secondary coverage, and Adobe's own post-event report was not among the sources reviewed^1,2.
