Taobao ranked first among the five marketplaces in a widely cited 2024 comparison by estimated third-party sales, followed by Tmall, Amazon, JD.com, and Shopee. That is a dated estimate, not a current 2026 leaderboard. “Biggest” can also mean buyers, visits, revenue, or another measure, and those rankings will not necessarily match.
What does “biggest online marketplace” mean?
The answer depends on the yardstick. Marketplace sales or gross merchandise value (GMV) measure transaction activity; active-buyer counts measure audience; revenue measures what a company earns under its accounting rules. Website visits, listings, and geographic reach describe other aspects of scale.
The comparison below uses estimated 2024 third-party sales: sales by independent sellers through a marketplace. Oberlo attributes the estimates to Digital Commerce 360. They are not a standardized set of audited disclosures, and they should not be read as total company revenue or as a 2026 ranking.
Largest marketplaces by estimated 2024 third-party sales
| Marketplace | Geography and model | Estimated 2024 third-party sales | Source and caveat |
|---|---|---|---|
| Taobao | China-focused consumer marketplace | $723.8 billion | Oberlo’s 2024 estimate, attributed to Digital Commerce 360; not an audited, harmonized company filing. |
| Tmall | China-focused consumer marketplace | $682.7 billion | Oberlo’s 2024 estimate, attributed to Digital Commerce 360; not an audited, harmonized company filing. |
| Amazon | International consumer marketplace | $435.7 billion | Oberlo’s 2024 estimate, attributed to Digital Commerce 360; distinguish it from Amazon’s reported revenue and other marketplace metrics. |
| JD.com | China-focused commerce platform | $249.9 billion | Oberlo’s 2024 estimate, attributed to Digital Commerce 360; not an audited, harmonized company filing. |
| Shopee | Consumer marketplace serving Asian and other markets | $77.2 billion | Oberlo’s 2024 estimate, attributed to Digital Commerce 360; not an audited, harmonized company filing. |
These figures and ordering come from Oberlo’s 2024 marketplace comparison. The source labels the figures as estimates or projections. Its third-party-sales framing is useful for a like-for-like snapshot, but the available information does not establish that every platform’s estimate uses identical treatment of refunds, shipping, taxes, or transaction scope.

Why company-reported marketplace figures do not make a clean global ranking
Companies publish metrics that can sound similar while covering different activity. eBay’s GMV is based on paid transactions on its marketplace platforms. Etsy’s GMS is the value of items sold, excluding shipping and net of refunds; its consolidated figure also covers marketplaces beyond Etsy. Neither measure should be inserted into the third-party-sales table as if it were calculated on the same basis.
- eBay: Reported $75 billion in 2024 GMV, 134 million active buyers at year-end, and 2.3 billion live listings. It said 49% of GMV came from outside the United States and that it operated in more than 190 markets. These describe eBay’s own reported scale, not a directly comparable estimate in the table. See its 2024 Form 10-K.
- Etsy: Reported $12.6 billion in consolidated 2024 GMS: $10.9 billion for Etsy marketplace, about $917.9 million for Reverb, and about $788.9 million for Depop. GMS is not revenue. Etsy marketplace had 89.6 million active buyers and 5.6 million active sellers at December 31, 2024. See the company’s 2024 Form 10-K.
- Amazon: The $435.7 billion figure above is the 2024 third-party-sales estimate in Oberlo’s comparison, not a claim about Amazon’s total sales or revenue. Amazon’s 2024 Form 10-K reports company results using its own accounting categories.
Even when two companies publish a transaction-value metric, comparisons require checking the period, geographic scope, inclusion of first-party sales, and treatment of refunds and shipping. A buyer count or revenue figure answers a different question from marketplace sales.
Which marketplace is largest for a particular purpose?
Absolute scale is only one way to choose a marketplace. A platform’s audience and product focus may matter more to a buyer, seller, or business sourcing inventory.
For broad consumer shopping
Amazon is the largest non-China platform in the cited five-marketplace list by estimated third-party sales. The ranking alone does not establish which marketplace offers the best selection, price, delivery, or seller terms for an individual shopper.
Rank #3
For resale and global choice
eBay’s reported buyer base, large live-listing count, and international activity illustrate its role as a broad marketplace with a strong recommerce dimension. Its figures use eBay’s own definitions and are not directly comparable to the table’s estimates.
For handmade and creative goods
Etsy describes its core marketplace as a global destination for unique creative goods from independent sellers. Reverb focuses on music gear, while Depop centers on apparel resale. Etsy’s consolidated GMS combines activity across those marketplaces, so it should not be mistaken for Etsy marketplace sales alone.
For wholesale sourcing
Alibaba.com serves businesses sourcing from suppliers, rather than functioning only as a consumer shopping destination. Alibaba Group reported more than 48 million buyers from over 190 countries for Alibaba.com sourcing or transaction activity in fiscal 2024, which ended March 31, 2024. That B2B figure is not a consumer-marketplace sales comparison. See the Alibaba Group FY2024 Annual Report.

The top-five figures are a 2024 estimate snapshot, not a verified 2025 or 2026 all-market ranking. A consistent, harmonized current ranking is not established by the cited sources: company reports use differing metrics and reporting periods. Use the table to understand the scale and ordering reported for that comparison, and check the latest company disclosures when a current company-specific figure matters.
