How many sellers are on Walmart Marketplace? 2026 statistics

How many sellers are on Walmart Marketplace? Walmart doesn't publish an official count. The most-cited independent estimate is from Marketplace Pulse, which estimated about 200,000 active sellers in June 2026, up from about 100,000 in September 2023. Walmart's own reports show the marketplace growing fast: in the quarter ended July 31, 2026, Walmart said its U.S. marketplace net sales grew more than 50%. Below are the numbers we could source, each with who said it and when.

Margenos makes this page. Margenos is a Walmart reseller tool (Chrome extension and Android app) that shows whether a product is worth selling on Walmart Marketplace: fees, profit, ROI, sales estimates, every competing seller with stock, the Buy Box winner and the product's price and Buy Box history. We don't have our own marketplace-wide seller count, so we only report numbers from Walmart or from named third parties.

How to read this page: "Walmart" means the number comes from Walmart's own corporate, investor or Marketplace pages. "Estimate" means a third party worked it out; treat those as estimates, not facts.

How many sellers on Walmart Marketplace: the count over time

Marketplace Pulse counts a seller as active based on what it sees on Walmart.com, so the figures depend on its method. In its September 2024 report it also found that international sellers, "nearly all from China," made up 35% of active sellers.

So, how many people sell on Walmart? Roughly 200,000 businesses by the best public estimate. A marketplace-wide count doesn't tell you how crowded any given product is. That varies listing by listing, which is why Margenos shows every competing seller and their stock on the product page. Our Walmart third-party sellers guide explains who these sellers are.

How big is Walmart Marketplace? Revenue and growth

Walmart doesn't report marketplace revenue or GMV as a dollar figure. It reports growth rates in its quarterly earnings releases. These are Walmart's own numbers:

For a dollar size, you need an estimate. Marketplace Pulse estimated Walmart's marketplace GMV at roughly $15 billion, around 10% of what it put at Walmart's $150 billion U.S. e-commerce business (Jun 4, 2026). That is an outside estimate, not a Walmart figure.

For context on the whole company, Walmart says approximately 280 million customers and members visit its more than 10,900 stores and eCommerce sites in 19 countries each week (Walmart corporate; the Marketplace site cites first-party data from Jan 2026). Most of those shoppers are store customers, not marketplace buyers.

Walmart advertising (Walmart Connect)

The ad numbers matter to sellers because more advertisers usually means paying more for visibility. Walmart's 5:1 figure is its own average; your results will depend on the product and the price.

What share of sellers use WFS?

Walmart doesn't publish the share of sellers using Walmart Fulfillment Services, but it does publish related numbers:

• Nearly 50% of the marketplace business flowed through fulfillment services, Walmart said in its Q2 FY27 release (Aug 20, 2026).
• 50% GMV growth, on average, for sellers using WFS, per Walmart first-party data from Feb 1, 2025 to Mar 27, 2026, on the Marketplace site.
• Two-thirds of top Walmart marketplace sellers use WFS, estimated Marketplace Pulse (Aug 29, 2024). The same article dates WFS's launch to February 2020.

How long has Walmart Marketplace been around?

Walmart launched its marketplace in August 2009. Walmart's own press release said the launch added "nearly one million new items" from three retailers: CSN Stores, eBags and Pro Team. Marketplace Pulse describes the marketplace as mostly dormant for its first seven years, with growth starting in 2016, the year Walmart acquired Jet.com. Walmart's marketplace has been around for more than 17 years, but most of its sellers joined in the last few.

Who are the top Walmart Marketplace sellers?

There's no official ranking. Walmart doesn't publish a list of its largest third-party sellers or their sales, and we haven't found a public, sourced "Walmart Marketplace third party sellers list" we'd trust. Lists you see online are usually estimates from tools that track storefronts.

For a reseller, the more useful question is who you'd compete with on a specific product. You can click "More seller options" on any Walmart.com listing, or use Margenos, which lists every seller on the listing with their price, stock and whether they use WFS, plus who's won the Buy Box over time. See our Walmart seller lookup guide.

What these statistics mean if you're thinking of selling

Growth cuts both ways. Marketplace sales growing more than 50% in a quarter means more buyers. Seller counts roughly doubling in under three years means more competition, and a big share of new sellers are international. Whether Walmart is worth it for you depends on the products, not the headline numbers. Read is selling on Walmart worth it, how much you can make selling on Walmart and what Walmart Marketplace is, and compare it in Walmart vs Amazon.
