Top 10 Largest E-commerce Companies Worldwide 2026

Hook Introduction

Alibaba alone moves more merchandise value each year than Amazon and Walmart’s e-commerce businesses combined, and it does it from a base that’s 88% concentrated in a single country. As the biggest e-commerce companies in the world continue to expand, Alibaba remains a dominant force among the largest online retailers worldwide.

We pulled the latest verified 2026 GMV rankings to show exactly which companies actually dominate global online retail, and why “biggest” and “most global” turn out to be two completely different titles. This guide ranks the top e-commerce companies 2026 and compares the top 10 e-commerce companies based on their global transaction scale.

Key Highlights (Quick Facts)

• Alibaba is the world’s largest e-commerce company by gross merchandise value (GMV), reaching US$1.26 trillion in 2025 — more than Amazon and Walmart’s e-commerce operations combined ($1.12 trillion together).
• PDD Holdings, parent company of Temu and Pinduoduo, ranks second globally at US$873.0 billion in GMV, ahead of Amazon.
• Amazon ranks third by GMV at US$851.9 billion, despite being the most-recognized global e-commerce brand and generating the highest reported revenue of any pure e-commerce company at roughly $574.8–638 billion.
• ByteDance’s TikTok Shop reached US$672.1 billion in GMV, a striking figure for a business built primarily around social/live-stream commerce rather than a traditional storefront.
• Alibaba’s GMV grew just 7.4% in 2025 — one of the slower growth rates in the top 10 — yet that percentage alone added roughly $87 billion in new sales, more than eBay’s entire annual total.
• China accounts for 88.28% of Alibaba’s total GMV, while Amazon’s base is far more distributed: the US contributes 50.89%, with the UK, Germany, Japan, Canada, and India each contributing meaningfully to the remainder.
• The fastest-growing companies in the top 10 are Sea Ltd (Shopee) at 26.77% and MercadoLibre at 26.37% — and remarkably, both are growing largely by colliding in the same market: Brazil.
• The global e-commerce market surpassed $6 trillion in 2026, with the top 50 platforms capturing the overwhelming majority of worldwide traffic and transactions.

A Note on How This Ranking Is Measured

This article ranks companies primarily by gross merchandise value (GMV) — the total value of everything sold through a company’s online platforms in a year — which is the standard, most comparable metric across companies with very different business models.

GMV is different from reported revenue. A marketplace like Alibaba or eBay collects fees on third-party sales, so its actual revenue is much smaller than its GMV. A first-party retailer like Amazon or JD.com books a much larger share of its GMV directly as revenue, since it often owns and sells the inventory itself. Neither number is “more correct” — they simply measure different things, and this article notes both where relevant to avoid an apples-to-oranges comparison.

The Top 10 Largest E-commerce Companies Worldwide

1. Alibaba Group

Alibaba is the world’s largest e-commerce company by GMV, reaching US$1.26 trillion in 2025 — a figure larger than Amazon and Walmart’s combined online businesses. Its ecosystem spans Taobao and Tmall domestically, AliExpress and Lazada internationally, and the Ant Group financial infrastructure that supports transactions across the network.

Alibaba’s size is a story of scale, not speed: its GMV grew just 7.4% in 2025, one of the slowest growth rates in the entire top 10, yet that modest percentage still added roughly $87 billion in new sales — more than eBay’s entire annual GMV. The company’s concentration is its defining vulnerability, though: China accounts for 88.28% of its total GMV, with no other single market reaching even 1%, leaving Alibaba’s fortunes tied tightly to one economy and one regulatory environment.

2025 GMV: US$1.26 trillion. Headquarters: Hangzhou, China. Primary markets: China (88%), South Korea (under 1%).

2. PDD Holdings (Temu / Pinduoduo)

PDD Holdings, the parent company behind both domestic Chinese platform Pinduoduo and international discount marketplace Temu, ranks second globally at US$873.0 billion in GMV — ahead of Amazon. Its model is built on social commerce, group buying, and aggressively low prices, a structural approach that differs sharply from Alibaba’s marketplace-plus-brand model.

Temu specifically has become one of the fastest-reach international expansions in e-commerce history, ranking among the top free shopping apps by unique US installations, according to industry app-tracking data — a genuinely disruptive presence in Western markets just a few years after launch.

2025 GMV: US$873.0 billion. Headquarters: Dublin/Shanghai (dual structure). Primary markets: China (Pinduoduo), global expansion via Temu.

3. Amazon

Amazon remains the most globally recognized e-commerce brand and the most geographically diversified company on this list, even though it trails Alibaba and PDD Holdings by GMV. Its GMV reached US$851.9 billion in the most recent tracking, while its reported annual revenue across all segments — including AWS cloud services and advertising — reaches roughly $574.8–638 billion, among the highest of any company in the ranking.

What genuinely sets Amazon apart is distribution of risk: the US contributes just 50.89% of its GMV, with eleven other countries — including the UK (9.52%), Germany (7.73%), Japan (6.99%), Canada (4.37%), and India (2.8%) — together accounting for nearly 95% of its total volume. That makes Amazon, despite trailing Alibaba by roughly $400 billion in total GMV, the most genuinely global company on this entire list.

2025 GMV: US$851.9 billion. Headquarters: Seattle, USA. Primary markets: US (51%), UK, Germany, Japan, Canada, India, and others.

4. ByteDance (TikTok Shop / Douyin)

ByteDance’s e-commerce operations, primarily TikTok Shop internationally and Douyin domestically in China, reached a striking US$672.1 billion in GMV — a figure achieved largely through live-stream and social commerce rather than a traditional browse-and-buy storefront model. Douyin alone generated an estimated $554 billion in GMV through live-stream commerce, a figure larger than Amazon’s entire US marketplace.

This represents one of the clearest signals in global e-commerce: social and live-stream commerce, pioneered at massive scale in China, has become a genuine top-tier revenue category rather than a niche trend, and TikTok Shop’s international expansion is actively exporting that model to Western markets.

2025 GMV: US$672.1 billion. Headquarters: Beijing, China. Primary markets: China (Douyin), global (TikTok Shop).

5. JD.com

JD.com differentiates itself structurally from marketplace-model competitors through its first-party retail model — JD owns its inventory and operates its own logistics network, rather than primarily hosting third-party sellers. This gives it a structural advantage in delivery reliability and customer satisfaction, particularly in electronics and premium categories where JD frequently outperforms Alibaba’s Taobao.

JD.com’s GMV reached US$555.7 billion, with the company holding roughly 24% of China’s domestic e-commerce market, and continues gaining share through aggressive expansion into commodities, electronics, and grocery categories where its controlled supply chain provides a genuine reliability edge over pure marketplace competitors.

2025 GMV: US$555.7 billion. Headquarters: Beijing, China. Primary markets: China-dominant.

6. Walmart

Walmart is the largest non-Asian e-commerce company outside of Amazon on this list, with online GMV reaching US$270.2 billion. Its e-commerce growth has been built substantially on integrating online ordering with its massive existing physical store and logistics network — a hybrid advantage that pure-play online retailers can’t easily replicate.

Combined with Amazon, Walmart’s online business brings total US-anchored e-commerce GMV to roughly $1.12 trillion when the two are added together — a figure ECDB specifically highlights as still smaller than Alibaba alone, illustrating just how concentrated Chinese e-commerce volume has become relative to the rest of the world.

2025 GMV: US$270.2 billion. Headquarters: Bentonville, Arkansas, USA. Primary markets: US-dominant, with growing international e-commerce.

7. Chengdu Kuaigou Technology (Kuaishou)

Kuaishou’s e-commerce arm, Chengdu Kuaigou Technology, reached US$220.0 billion in GMV — another Chinese live-stream and short-video commerce platform demonstrating how deeply social commerce has penetrated the world’s largest e-commerce market. Alongside Douyin, it represents China’s broader “super-app commerce” phenomenon, where shopping, social media, and live entertainment increasingly converge into a single platform experience.

Its presence in the global top 10 — a company far less recognized internationally than Amazon or Alibaba — underscores how much of the truly massive scale in global e-commerce remains concentrated in Chinese domestic platforms that most Western consumers have never directly used.

2025 GMV: US$220.0 billion. Headquarters: Beijing, China. Primary markets: China-dominant.

8. Sea Ltd (Shopee)

Sea Ltd, parent company of Southeast Asian marketplace giant Shopee, posted GMV of US$127.4 billion — but the more striking number is its growth rate: 26.77%, the fastest of any company in the global top 10. Shopee built its foundation in Southeast Asia through integrated payments and live commerce, but its most notable recent growth has come from an unexpected direction.

Sea Ltd now pulls 23.71% of its total GMV from Brazil — worth roughly $30.2 billion — a figure that has crept up to nearly match MercadoLibre’s home-market total in the same country. This represents a direct, escalating competitive collision between two of the fastest-growing companies on this entire list, both fighting for share in the same Latin American market.

2025 GMV: US$127.4 billion. Headquarters: Singapore. Primary markets: Southeast Asia, increasingly Brazil.

9. eBay

eBay remains a genuinely global marketplace despite its more modest scale relative to the giants above it, reaching US$80.7 billion in GMV. Unlike most companies on this list, eBay operates almost entirely as a customer-to-customer and small-business marketplace rather than competing on first-party retail or live-stream commerce.

Its comparatively modest growth in recent years stands in contrast to the double-digit growth rates posted by companies like Sea Ltd and MercadoLibre — Alibaba’s single year of GMV growth alone ($87 billion) exceeded eBay’s entire annual GMV, illustrating just how much the scale gap between the top and bottom of this ranking has widened.

2025 GMV: US$80.7 billion. Headquarters: San Jose, California, USA. Primary markets: Global, with strength in the US and Europe.

10. MercadoLibre

MercadoLibre rounds out the top 10 at US$65.0 billion in GMV, but like Sea Ltd, its headline number is growth: 26.37%, nearly matching Shopee’s pace and making it one of the fastest-growing e-commerce companies in the world. It has dominated Latin American e-commerce for over two decades, drawing 49.66% of its total GMV from Brazil — worth approximately $32.3 billion — its long-held home-market stronghold.

That Brazilian dominance is now under direct pressure: Sea Ltd’s Shopee has grown its own Brazilian GMV to nearly match MercadoLibre’s home-turf total, setting up what’s likely to be one of the most closely watched regional e-commerce battles of the next several years.

2025 GMV: US$65.0 billion. Headquarters: Buenos Aires, Argentina (Montevideo, Uruguay incorporation). Primary markets: Brazil (50%), broader Latin America.

Source: ECDB.com 2026 GMV rankings (published July 2026, based on 2025 fiscal-year data). GMV figures are not directly comparable to reported company revenue, since marketplace models (Alibaba, eBay) collect fees on GMV rather than booking it as direct revenue, while first-party retailers (Amazon, JD, Walmart) book a larger share of GMV as revenue.

Step-by-Step: How GMV Rankings Are Calculated

1. Total transaction value is aggregated across all platforms a company owns. For Alibaba, this means combining Taobao, Tmall, AliExpress, and Lazada into one consolidated ecosystem figure.
2. GMV counts the value of goods sold, not company earnings. A high-GMV company isn’t necessarily more profitable — this number reflects transaction volume, not the bottom line.
3. Currency conversion and reporting periods are standardized. Since companies report in different currencies and fiscal calendars, figures are converted to US dollars and aligned to comparable annual periods.
4. Growth rates are calculated year-over-year in absolute dollar terms, not just percentage. This matters because a slow percentage grower like Alibaba can still add more absolute revenue than a faster percentage grower with a smaller base.
5. Regional concentration is calculated separately from total GMV. This reveals which companies are genuinely globally diversified (like Amazon) versus concentrated in one dominant market (like Alibaba in China).

Pros and Cons Table: GMV vs. Revenue Rankings

Ranking Method	Pros	Cons
GMV (this article’s primary metric)	Fairest comparison across different business models; reflects true transaction scale	Doesn’t reflect profitability or actual company earnings
Reported revenue	Reflects a company’s actual booked income and financial health	Unfairly disadvantages marketplace models (Alibaba, eBay) that only collect fees, not full sale value
Market capitalization	Reflects investor confidence and growth expectations	Highly volatile; doesn’t measure operational scale at all

Comparison Table: Largest E-commerce Company by Region

Social/live-stream commerce	ByteDance (Douyin/TikTok Shop)	US$672.1 billion	Douyin alone exceeds Amazon’s entire US marketplace
US big-box retail e-commerce	Walmart	US$270.2 billion	Built on hybrid online-plus-physical-store advantage
Global C2C marketplace	eBay	US$80.7 billion	Modest scale but genuinely global reach

2026 News and Trends

The clearest 2026 storyline is that social and live-stream commerce has become a legitimate top-tier category, not a niche trend. ByteDance’s combined Douyin and TikTok Shop operations reached $672.1 billion in GMV — with Douyin’s live-stream commerce alone generating more than Amazon’s entire US marketplace — while Kuaishou’s e-commerce arm added another $220 billion through the same social-commerce model.

The most closely watched regional battle in 2026 is unfolding in Brazil, where Sea Ltd’s Shopee and MercadoLibre are posting the two fastest growth rates in the entire top 10 (26.77% and 26.37% respectively) by directly competing for the same market. Shopee’s Brazilian GMV has grown to nearly match MercadoLibre’s two-decade home-market stronghold, setting up sustained competitive pressure that’s likely to reshape Latin American e-commerce through the rest of the decade.

Scale concentration at the very top continues to intensify: Alibaba’s modest 7.4% growth rate in 2025 still added roughly $87 billion in new sales — more than eBay’s entire annual GMV — illustrating how a small percentage gain at massive scale now outweighs large percentage gains almost everywhere else in the ranking. Meanwhile, geopolitical friction and domestic competitive pressure from PDD and JD continue constraining Alibaba’s ability to meaningfully expand its international footprint beyond China.

Conclusion

Alibaba remains the world’s largest e-commerce company by GMV in 2026, but its dominance is a story of scale within one country, not global reach,  a distinction Amazon, despite ranking third, holds instead. The fastest-moving story in the ranking belongs to Sea Ltd and MercadoLibre, whose head-to-head battle for Brazil is reshaping Latin American e-commerce in real time.

Whichever company tops next year’s list, the underlying trend is consistent: social commerce, regional battles, and the widening gap between GMV giants and everyone else will keep defining global e-commerce through the rest of the decade.
