Amazon wanted more people to join Prime, and one big sale day was the cleanest way to do it. This is when Prime Day first began in July 2015 as a one-day birthday promotion.
Eleven events later, it has become something much bigger. The 2025 edition stretched across four days, ran in more than 25 countries, and drove an estimated $24.1 billion in U.S. online spend across every retailer, not just Amazon.
This guide pulls together the most recent Prime Day statistics in one place, with sources you can verify. SmartScout tracks Prime Day closely because the patterns that surface during the event tend to shape seller strategy for the rest of the year.
Key Prime Day Statistics at a Glance
- Shoppers in the US spent $24.1 billion online in 2025 across all retailers, up 30.3% year over year
- 53.2% of transactions happened on mobile devices, with smartphones contributing $12.8 billion in Prime Day Sales 2025
- The average order value was $53.34, and the average household spent around $156.37
- 67% of items sold were priced under $20
- Traffic from generative AI tools to U.S. retail sites jumped 3,300% year over year during the Prime Day event
- Buy Now, Pay Later orders accounted for a total of 8.1% of all online orders, totaling $2 billion across four days
Amazon Prime Day Sales Statistics
Amazon does not publish Prime Day-specific revenue figures. The numbers below come from third-party analysts, mainly Adobe Analytics for U.S. spend and Statista's compiled series.
Methodologies and geographic coverage differ between sources, so these are estimated numbers rather than exact figures.
Sources: Statista global series, Statista U.S. series, and Adobe Analytics for 2025. The 2025 figure measures total U.S. retailer online spend during the window, not Amazon-only revenue.
The format change is the single biggest reason 2025's headline number was up 30% year over year. Longer event, more transaction time, more reported revenue. For context, the 2025 four-day total roughly matched the combined 2024 Black Friday and Cyber Monday online sales.
Per-day intensity actually dropped. NielsenIQ's panel data shows the average daily order total in 2025 was 136% above Amazon's year-to-date daily average, versus 247% above the year-to-date daily average in the 2024 two-day event.
So the event is bigger overall, but each individual day is less concentrated than before.
Prime Day Shopper Statistics
About 89% of 2025 Prime Day shoppers said they had shopped a previous Prime Day, and 87% identified as Prime members of more than a year.
A further 96% of shoppers knew it was Prime Day before they shopped, and 52% said Prime Day was their primary reason for visiting Amazon during that period.

Walmart Deals, Target Circle Week, and Best Buy's Black Friday in July all pulled real Prime Day attention. 49% of Prime Day shoppers also shopped Walmart, 38% shopped Target Circle Week, and 11% shopped Best Buy. And 57% of Prime Day shoppers compared Amazon's prices to other retailers before placing orders.
Prime Day Consumer Spending Statistics
The average Prime Day order in 2025 was $53.34, down roughly 8% from $57.97 in 2024. But shoppers placed more separate orders. Roughly 63% of households placed two or more, which pushed average household spend up to $156.37, a 2.6% bump from $152.33 the prior year.
Here is how that broke down by order size and order count:

The pattern is clear once you see the per-item average. Spend per item dropped to $24.59 in 2025 from $28.47 at the same point in 2024. More orders, cheaper items. This was a stock-up event, not a splurge event.
BNPL hit a new high in 2025. It accounted for 8.1% of online orders, up from 7.4% the year before, and totaled $2 billion in spend across the four days, growing 33.3% year over year. Adobe's survey respondents reached for BNPL most often in apparel, electronics, home goods, and health and beauty.

Biggest category lifts on Prime Day
Adobe measures category lift differently. It compares Prime Day sales against the daily average from June 2025, which surfaces where Prime Day pulled in disproportionate demand:

Mobile Shopping & Ecommerce Trends
For the first time in any Prime Day, mobile revenue beat desktop revenue. Smartphones generated 53.2% of online sales, roughly $12.8 billion in spending. The 2024 share was 49.2%, so this is not a small jump. It is a structural shift.
Mobile is now the primary driver of e-commerce sales overall, which has real consequences for how sellers should design listings and ads. Mobile-first product imagery, A+ content that renders on small screens, and ads optimized for thumb scrolling all matter more than they did a year ago.
Prime Day Seller Statistics
Most coverage of Prime Day focuses on what consumers did. The seller side often matters more for strategy. Ad costs, conversion rates, and inventory positioning shape outcomes that the GMV number cannot show.
Ad spend and CPC trends
Skai called Prime Day 2025 the biggest Prime Day in Amazon Ads history, though year-over-year ad spend growth was slower than in prior years. Across Skai's client base, daily averages outperformed the 30-day baseline.
Clicks were up 108%, impressions up 114%, click-through rate climbed, and cost-per-click actually fell. That pattern says advertisers paced their budget across all four days instead of front-loading day one.
Halo effects beyond direct deals
Even brands that did not run formal Prime Day deals saw a sales lift. Acadia's data shows roughly a 46% lift versus their normal weekly baseline during the event. That changes the question for many sellers from "should we run a deal" to "are our listings, inventory, and ads ready for the surge either way?"
Prime Day 2026 timing has compressed seller prep
Prime Day 2026 is expected in late June rather than mid-July, with industry sources pointing to roughly June 23 to 25. Deal submissions are expected to open in late March and close on May 26. For sellers who used to treat July as a soft prep target, the calendar has shifted by about a month. Inventory and ad planning should start in March, not June.
Prime Day Pricing & Discount Statistics
This is the section that gets the least attention in most Prime Day roundups, which is exactly why it matters. Omnia Retail's proprietary analysis found that the overall average discount depth across discounted Amazon US products in 2025 was around 21.7%.
Amazon's own tech brands like Fire TV, Echo, Kindle, and Ring averaged about 30% off, and Amazon Private Brands ran up to 40% off. For third-party products, the picture was more complicated.
Omnia's most striking finding: 45.5% of products were priced higher during Prime Day 2025 than the week before the event. Only 0.6% of products saw price reductions of more than 20% from the pre-event baseline. For most listings, the "Prime Day discount" reverted prices to where they had been a month earlier, instead of offering a genuinely new low.
Adobe's view shows higher peak discounts
Both views can be accurate at the same time. Adobe measures peak discount depth against listed prices, not pre-event street prices. By that view, here is how the major categories landed:

Practical takeaway: price-tracking tools like CamelCamelCamel and Keepa saw a spike in usage during the 2025 event. Consumer skepticism about promotional pricing is rising, not falling, and sellers who set genuine discounts off durable baselines will earn more trust than those who inflate prices first.
AI & Prime Day Shopping Trends
This is the fastest-growing storyline in e-commerce, and Prime Day 2025 is the cleanest evidence point so far. Traffic to U.S. retail sites from generative AI sources like ChatGPT, Perplexity, AI-powered browsers, and shopping assistants jumped 3,300% year over year during the four-day event. For context, the same traffic was up 1,300% during the 2024 November to December holiday window. The curve is accelerating, not flattening.
Inside Amazon, Rufus, the AI-powered shopping assistant, handled an estimated 274 million queries per day by October 2024, about 13.7% of all Amazon searches, with that share projected to reach 25 to 35% by the end of 2025. To handle Prime Day volume, Amazon deployed roughly 80,000 AWS AI chips to process about 3 million tokens per minute for Rufus queries.
AI is still small compared to traditional channels in absolute terms. During Prime Day 2025, paid search drove 28.5% of online retail revenue (up 5.6% YoY), and affiliates and partners drove 19.9% (up 15%). But AI-referred visitors convert 31% better than non-AI traffic, and revenue per visit is up 254% year to date. The channel does not have to overtake paid search to start mattering.
For sellers, the practical implication is direct. Product listings need to be AI-ready. That means clear, structured answers to common customer questions inside the listing, reviews that surface key features, and titles and bullets written in a way that an LLM can summarize cleanly.
Amazon Prime Day vs Black Friday Statistics
Prime Day has steadily narrowed the gap to Black Friday on most metrics, and in some cases, passed it. The 2025 four-day Prime Day generated more total online retail spend than the 2024 Black Friday and Cyber Monday combined.
Sources: Adobe Analytics, Queue-it Black Friday compilation, Numerator.
Comparing a four-day event to a one-day Black Friday flatters Prime Day. The fairer reading is that Prime Day is now Amazon's mid-year demand peak, comparable to but not yet a replacement for the November to December window. Black Friday still has a broader cultural reach, since 36% of consumers planned to shop it in 2024, versus 32% who planned to shop Prime Day.
Prime Day Statistics for Small Businesses
Amazon frames Prime Day as a small-business event, and the data partially supports the narrative. Capital One Shopping estimates small businesses made roughly $3.63 billion in sales during Prime Day 2024). Independent sellers, described by Amazon as mostly small and medium-sized businesses, sold more than 200 million items during the two-day 2024 event.
The official recap says independent sellers achieved record sales and a record number of items sold, but Amazon withheld the specific unit count for the first time since 2020. That is a notable break from past disclosures. Amazon previously shared 375 million units for 2023, over 300 million for 2022, and over 250 million for 2021.
Third-party seller share has been trending up for years. Marketplace items now account for roughly 60% of total Amazon retail sales. For independent sellers, that means Prime Day is increasingly about competition among thousands of marketplace listings rather than Amazon's first-party deals. That is exactly where SmartScout's marketplace intelligence shows up.
Methodology
We compiled this report from multiple publicly available sources, drawing on a mix of primary disclosures (Amazon's official Prime Day recaps, press coverage, and SEC-tracked retail reporting) and third-party analytics platforms (Adobe Analytics, Numerator, NielsenIQ, Statista, and others).
Because Amazon does not disclose Prime Day-specific revenue or unit figures for most metrics, several of the numbers in this article are estimates produced by independent analysts and agencies. Methodologies and geographic coverage differ between sources, so we have flagged those distinctions throughout the article rather than treating every figure as an exact measurement. All data reflects what was available as of November 2025.
