Americans spent roughly $1.2 trillion shopping online last year, and on a single day, Cyber Monday, they spent more than $14 billion, the biggest e-commerce day in US history, at a peak of $16 million a minute. The best US eCommerce stats capture both that staggering scale and a quieter truth beneath it: online is still only about a sixth of total US retail, Amazon dominates it almost as it did a decade ago, and the real action is in when and how people buy, not just how much.
We track deals and shopping behaviour at Coupo9, so US e-commerce data is home turf. It shows where discounts concentrate (a few tentpole sale days that dwarf the rest of the year), how shoppers behave (nearly three-quarters abandon carts, most over shipping costs), and where the market is heading (AI-assisted shopping, social commerce, groceries moving online).
One note on sourcing, because e-commerce data is unusually prone to confusion. The authoritative figure for US online sales is the US Census Bureau, and we anchor to it. Other widely quoted stats come from Adobe Analytics (holiday spending), the National Retail Federation (returns), Baymard Institute (cart abandonment) and eMarketer (forecasts). Where a number is official we say so; where two credible sources disagree, we flag it, because the methodology behind an e-commerce number matters as much as the number.
Read on and these US eCommerce stats stop being a blur of trillion-dollar figures and become a clear map of how, and when, America shops online.
Market size: a $1.2 trillion machine
US e-commerce sales reached about $1.2 trillion in 2025 per Census-based figures, after roughly $1.19 trillion in 2024. This is a market that first crossed a trillion dollars only in 2022, so the scale is both enormous and recent, and an estimated 288 million Americans, over 81% of the population, now shop online.
The growth story has a twist. E-commerce grew explosively during the pandemic (up 30% in 2020) but has since settled into steadier single-digit growth, around 5% to 8% a year, making 2025 the fourth straight single-digit year. Yet the most recent Census reading showed a re-acceleration to nearly 10%, so the maturing market is not as sleepy as it looked, and it is forecast to climb toward $1.7 trillion by the end of the decade. You will also see bigger totals quoted, near $1.44 trillion from eMarketer, which uses a broader definition. Neither is wrong; they measure slightly different things.
The 16% question: how much of retail is really online
Here is the single most misunderstood statistic in e-commerce. You will see US online shopping described as both 16% and 23% of retail, and both are correct, because they measure different things. The US Census Bureau, the official source, puts e-commerce at about 16% of total US retail, but that denominator includes categories that barely sell online: cars, gasoline and restaurant meals. Digital Commerce 360 strips those out to measure against the retail that could plausibly move online, which pushes the figure to about 23%, and above 25% in the final quarter of 2025.
Online shopping is 16% of all retail, or 23% of the retail that could go online. Both numbers are right.
The gap tells you two true things at once: online is still a minority of American spending (about 80% of retail dollars are still spent in physical stores), yet in the categories where online competes it is already approaching a quarter of sales and climbing. Brick-and-mortar is not dying, but for the things you are most likely to buy online, electronics and apparel, the internet is fast becoming the default. The share has more than tripled since 2010.
Where the dollars go: the top categories
The two biggest online categories are computers and consumer electronics (around $219 billion, over a fifth of all e-commerce) and apparel and accessories (around $204 billion). Together those two make up more than 40% of every US e-commerce dollar.
| Category | Approx. online sales | Share of e-commerce |
|---|---|---|
| Computers and electronics | ~$219 billion | ~21% |
| Apparel and accessories | ~$204 billion | ~20% |
| Furniture and home | growing | ~15% |
| Groceries | fast-growing | ~19% by 2026 |
The most important shift is groceries, long the last holdout of in-store shopping. Online grocery is now the fastest-moving frontier, worth well over $200 billion and growing around five times faster than in-store grocery, on track to become the single largest e-commerce category by 2026 and to pass 25% of grocery spending by 2028. About 93% of grocery shoppers now buy both online and in-store. Beauty, health and personal care are the fastest-growing categories by percentage. The catch for shoppers is that grocery is where convenience fees bite hardest: delivery charges, service fees and marked-up per-item prices can quietly erase the savings, so check the per-unit price and use the digital coupons.
Who dominates: Amazon, Walmart and the share war
One company towers over US e-commerce. Amazon accounts for somewhere between 36% and 40% of all US online sales depending on the methodology, capturing close to 40 cents of every e-commerce dollar, on US online sales of around $440 billion a year, more than three times its nearest rival. Its wider business is broken down in our Amazon statistics guide.
That rival is Walmart, and the real story is momentum. Walmart's e-commerce is growing about 27% a year against Amazon's roughly 10%, and since 2022 its online sales have more than doubled while Amazon's grew about 63%. Walmart's online business now makes up about 20% of its total sales, up from 11%. Beyond the top two, Apple, eBay, Target and Costco each hold low single-digit shares. Amazon's dominance makes it the default, but a default is not the same as the cheapest, which is exactly why comparing across at least two retailers before buying still pays.
The Chinese disruptors and the tariff shock
The most dramatic recent story is the rise, and sudden stumble, of the ultra-cheap Chinese retailers Temu and Shein. Both exploded into the US on rock-bottom prices, with Temu's global merchandise volume hitting $35 billion in the first half of 2025, and together they had captured an estimated $15 billion of US e-commerce. Then the rules changed. For years they relied on the "de minimis" exemption, which let packages under $800 enter duty-free, and more than a billion such parcels a year were flooding in. That exemption ended on August 29, 2025, and Temu's US daily users promptly fell roughly 48% as prices rose to reflect the new tariffs. The lesson: prices too good to be true sometimes depend on a rule that can change.
How Americans shop: mobile, and Amazon-first
Americans increasingly shop with their thumbs. Mobile accounts for about 45% of US e-commerce over a full year, but that share spikes to 56% during the holiday season and 66% on Christmas Day, when people shop from couches rather than desks. US mobile retail spending now runs around $577 billion a year. One catch worth knowing: cart abandonment is far higher on mobile (about 86%) than desktop (about 70%), because small screens make comparing prices and entering payment details fiddly.
Where shopping decisions get made is more Amazon-centric than even the market-share figures suggest. About 86% of shoppers start their product research online, and roughly 61% begin on Amazon, against about half on Google and a third on Walmart. Among Gen Z, though, Google (38%) edges out Amazon (36%), and 11% start on TikTok, a sign of where discovery is heading. The most actionable behaviour stat is cart abandonment: about 70% of carts are abandoned before purchase, per Baymard Institute, and 39% of the time it is over unexpected extra costs like shipping and taxes, 21% over slow delivery, and 19% because a site forces account creation. Those abandoned carts are often the right call.
The sale-event economy: where the deals actually live
US e-commerce discounts are wildly concentrated into a handful of days, which is the single most useful thing for a deal-seeker to know. The 2025 holiday season drove a record $257.8 billion online, but the intensity clusters on specific dates: Cyber Monday hit $14.25 billion, the biggest online shopping day in US history, followed by Black Friday at $11.8 billion (broken down fully in our Black Friday statistics) and Thanksgiving at $6.4 billion.
Amazon's Prime Day, now a four-day July event, drove $24.1 billion in US online spending, more than two Black Fridays combined, and 25 separate days in 2025 each topped $4 billion online. The discount depths tell you where to focus: at the 2025 peak, electronics hit average discounts of 30.9%, toys 29.6%, apparel 25.1% and TVs 24.3%, while furniture and appliances saw shallower cuts near 19% to 20%. The deepest, most reliable discounts land on these tentpole events, especially for electronics and toys, so timing a big purchase to Cyber Week or Prime Day beats buying on impulse, a pattern we map out in our guide to the best time to buy online.
Payments and the buy-now-pay-later boom
How Americans pay is shifting fast, and one trend stands out for its risks. Digital wallets now handle about 39% of US e-commerce payments, up from 15% a decade ago, and are projected to pass half by 2030. But the fastest-growing method is buy-now-pay-later. BNPL spending hit $20 billion over the 2025 holiday season, with a record $1.03 billion on Cyber Monday alone, about 82% of it on mobile, and roughly 86.5 million Americans now use it. The honest warning is that BNPL is engineered to increase spending: splitting a $200 purchase into four $50 payments makes it feel cheaper than it is, which is precisely why retailers push it. It is fine for a planned purchase you could afford outright, and a trap when it nudges you to buy more than you would have paid for in one go. In India the equivalent lever is card and UPI offers, which we cover in using bank offers during online sales.
The returns problem nobody talks about
Behind the sales figures sits a massive, expensive reverse flow. Americans were expected to return about $850 billion of merchandise in 2025, and online purchases are returned at more than double the rate of in-store ones, roughly 19% for e-commerce versus under 9% in physical stores, according to the National Retail Federation. Returns cost retailers an estimated $20 to $30 per item to process, and about 9% are fraudulent. That expense gets baked into prices and, increasingly, into stricter policies: shorter windows, return fees and "keep it" refusals are spreading. The free, no-questions-asked return you assume you have may now come with a fee or a deadline, so check the return policy before you buy anything you might send back.
Retail media: the hidden profit engine
One of the most consequential shifts in US e-commerce is invisible to most shoppers: retail media, the advertising retailers sell on their own sites. It is now one of the biggest ad markets in the country, worth about $60 billion in 2025 and forecast to pass $100 billion by 2027.
Amazon dominates it, capturing an estimated 80% of US retail media spending, with its ad business alone bringing in more than $68 billion in 2025. Walmart Connect is a distant second at about 8%. Together they soak up nearly 90% of every new retail-media dollar. This is the honest catch behind those "sponsored" results: when you search on Amazon or Walmart, the first products you see are increasingly the ones that paid the most to be there, not the cheapest or best-rated, and that ad cost gets baked into prices. Scroll past the sponsored listings, sort by price or rating, and treat the first screen as an ad break.
Social commerce and the TikTok Shop surge
Shopping is moving into social feeds. US social commerce, buying directly through TikTok, Instagram and Facebook, reached about $87 billion in 2025, up more than 21%, and is projected to top $100 billion in 2026, with roughly 108 million Americans making a social purchase. The engine is TikTok Shop, which grew to about $15.8 billion in US sales in 2025, more than doubling year over year as its US buyer base grew from 35 million to over 65 million. It blends entertainment, influencer enthusiasm and one-tap checkout into an experience engineered for impulse, removing the pause where you would normally compare prices, so when a video makes you want to buy, screenshot the product and check its price elsewhere first.
AI is reshaping how people shop
The newest and fastest-moving trend is AI guiding purchases. Traffic to US retail sites from generative-AI tools like ChatGPT, Gemini and Perplexity surged nearly 700% year over year during the 2025 holiday season. AI-referred shoppers also behave better from a retailer's view: they convert about 31% more often, spend 45% more time on site, and are a third less likely to bounce, because they arrive with specific, AI-guided intent. AI assistants are a genuinely useful research tool, but an AI recommendation is only as neutral as its sources, and as brands learn to influence what it surfaces, these answers will face the same commercial pressures as search results. Use AI to research and shortlist, then verify the actual price and seller yourself.
The deal-seeker's America
Deal-seeking is mainstream, not niche, which is the encouraging part of this whole picture. About 172 million US consumers redeemed a digital coupon in 2025, roughly 90% of Americans have used a coupon, and 62% actively look for a promo code when shopping online, nearly all of it (about 94%) on mobile. The behaviour behind those numbers is dissected in our coupon statistics roundup.
Free shipping is the other decisive lever: 92% of shoppers say a free-shipping offer directly influences their purchase, up from 83% a year earlier, and 66% now expect it on every order. Deal-seeking works, and the shoppers who do it keep real money, but the data also shows the trap: 66% admit to an impulse buy prompted by a coupon. A deal is only a deal if you needed the item.
The business side: who sells online
Behind the trillion-dollar market is a vast seller ecosystem. Direct-to-consumer brands generated about $240 billion in 2025, nearly a fifth of US retail e-commerce, many powered by Shopify, whose merchants processed $378 billion in sales globally, up 29%, making Shopify and Amazon together roughly half of all US e-commerce. On Amazon itself there are more than 547,000 active US-based sellers, over 100,000 of them past $1 million in annual sales in 2025 (up from around 60,000 in 2021), and third-party sellers now account for 61% to 62% of everything sold there. So the majority of what looks like "buying from Amazon" is really buying from an independent business through Amazon, which is exactly why the "sold by" name, with its different pricing, warranty and returns, is worth a glance on any real purchase.
Methodology and how reliable these numbers are
Match your confidence to the source. The most reliable figures, total US online sales and retail share, come from the US Census Bureau; holiday and sale-day spending from Adobe Analytics; returns from the National Retail Federation; and cart abandonment from Baymard Institute's meta-analysis. These are authoritative and we lead with them. The next tier, forecasts and market-share splits from eMarketer, Digital Commerce 360, Statista and Capital One Shopping, is informed but disagrees by methodology (total US e-commerce is put at $1.23 trillion to $1.44 trillion, and online's share of retail at 16% or 23%, both defensible). Market-share splits (Amazon's US share ranges 36% to 40%) and category breakdowns are the least certain, so we have given ranges. For hard market-size numbers, check the Census Bureau's retail e-commerce reports.
US versus the world: China's lead, and where India fits
The United States is the world's second-largest e-commerce market, not the biggest. China dwarfs it, with online sales around $3.45 trillion, roughly half of all global e-commerce and nearly triple the US total, which itself is about a fifth of the worldwide market of roughly $7 trillion. On penetration the US ranks lower than you would expect: China's online share of retail is around 47% against the US at about 16%, so several countries shop online more intensively than Americans do.
For our Indian readers, the comparison is instructive. India's e-commerce market is far smaller in dollar terms (roughly $120 billion) but growing much faster, around 20% a year, and it is already the world's second-largest by number of online shoppers. Many trends that are mature in the US, mobile-first shopping, sale-event concentration, social commerce, are playing out faster and more mobile-heavily in India, where festival sales like the Great Indian Festival mirror America's Cyber Week. The US shows where a market goes at scale; India shows how fast it can get there.
The trillion-dollar machine, mapped
The real value in these US eCommerce stats is that they turn a trillion-dollar abstraction into a usable map: online shopping is a sixth of American retail and rising, Amazon owns nearly 40% of it, the deepest discounts hide in a handful of sale days, and how you pay and what you return increasingly shape what the whole thing costs you. The market is huge, maturing, and more concentrated than its size suggests, which is exactly why knowing its patterns pays.
So use the map. Time big buys to Cyber Week and Prime Day, where the real discounts live. Compare beyond Amazon, since its dominance is about default, not price. Watch the final total, use buy-now-pay-later with discipline, and read the return policy before the era of free returns fully closes. Whether you shop in Dallas or Delhi, the lesson these US eCommerce stats teach is the one we always return to: the market is enormous and engineered to make spending easy, so the shopper who understands its patterns keeps the most money.
FAQs
US e-commerce reached about $1.2 trillion in 2025 per Census-based figures, roughly 16% of total US retail sales, and is forecast to keep growing at mid-to-high single digits toward $1.7 trillion by the end of the decade.
