Add up the live store counts BuiltWith’s technology crawl tracks across the six leading ecommerce platforms and the total comes to more than 18.18 million active online stores as of mid-2026, led by Shopify’s 6.99 million and WooCommerce’s 6.38 million. That figure only covers six major platforms; broader estimates that fold in every custom-built, self-hosted, and niche storefront run as high as 30.7 million. Neither number is wrong. They are measuring different things, and the gap between them is the real story behind “how many online stores are there.”
How many online stores are there worldwide in 2026?
There is no single official register of online stores, so every published count depends on which sites the researcher’s crawler can actually detect. BuiltWith, which scans the live web for the technology fingerprints that platforms like Shopify and WooCommerce leave behind, currently detects 18,180,479 live stores across the six platforms it reports individually: Shopify, WooCommerce, Wix Stores, Magento, Squarespace Commerce, and BigCommerce.
That is a floor, not a ceiling. It excludes custom-built storefronts with no detectable platform signature, stores on smaller regional platforms, and marketplace-only sellers with no independent website at all. Broader estimates that try to capture that long tail land between 24 million and 30.7 million sites, depending on methodology and crawl date.

The takeaway: any single “X million online stores” headline is a snapshot of one crawler’s coverage, not a census, so the platform behind the number matters as much as the number itself.
How many Shopify stores are there?
6,990,890 stores currently run on Shopify, according to BuiltWith’s live crawl, making it the single largest platform by live count. Shopify itself stopped publishing an exact merchant count in its investor materials after reporting 2.063 million merchants in 2021, shifting its public disclosures to gross merchandise volume and revenue instead. That change is why every current-year Shopify count, including this one, now comes from third-party crawlers rather than the company’s own filings.

Growth since 2021 has clearly continued, just under a different reporting regime. BuiltWith’s 6.99 million live figure, plus 6,553,178 expired Shopify sites out of 13,544,068 ever tracked, suggests the platform has more than tripled in cumulative reach since that last disclosed number, even after accounting for churn.
Shopify’s own count stopped at 2021; every figure since has to be reconstructed from the outside.
Which ecommerce platform hosts the most stores?
By raw live count, Shopify and WooCommerce are close, at 6.99 million and 6.38 million respectively. By market share among higher-traffic sites, the picture sharpens: Shopify holds 28.6% of the top 1 million websites running any ecommerce platform, according to The Retail Exec’s Q1 2025 analysis, more than double WooCommerce’s 13.8% share of that same top-traffic slice.

The two rankings measure different things: BuiltWith’s live count is every detectable storefront regardless of traffic, while The Retail Exec’s share is limited to the top 1 million sites by rank. A platform can lead on raw count and lead again on high-traffic share, as Shopify does here, or lead on one and lag on the other.
Store count and market share are related but not the same metric, and headlines that swap one for the other without saying which is being cited are a common source of the conflicting numbers in this space.
How many online stores fail or shut down?
Every platform BuiltWith tracks shows meaningful churn between stores ever created and stores still live today. Shopify has the best retention of the six at 51.6% of all Shopify sites ever detected still live, while Squarespace Commerce retains just 15.1% and Magento retains 16.9%.

Some of this gap reflects platform mechanics rather than store failure alone. WooCommerce is a WordPress plugin, so its “ever tracked” figure includes sites that installed it briefly, migrated away from WordPress entirely, or let a domain lapse without ever processing a sale, not only stores that formally closed. Treat platform retention as a proxy for durability, not a precise business failure rate.
Geography concentrates the count as much as platform choice does. The United States hosts 49% of all e-commerce domains, more than 13.98 million stores, according to BuiltWith data cited by ElectroIQ’s July 2025 analysis. The United Kingdom is a distant second at roughly 1.24 million, followed by Brazil, Germany, and Australia in the low hundreds of thousands to low millions. That concentration tracks a broader pattern in US web adoption: see our analysis of how many small businesses have a website in 2026 for the wider context beyond stores with checkout functionality specifically.

A new store owner picking a platform for the long term is choosing a retention profile as much as a feature set, and the data shows those profiles differ by a factor of three or more.
Why do published store counts vary so much?
Three different methodologies produce three different families of numbers, and none of them is measuring quite the same population.

A raw platform crawl like BuiltWith’s counts every detectable live storefront, a traffic-ranked share report like The Retail Exec’s only counts sites popular enough to register in the top 1 million, and a broad market estimate tries to extrapolate beyond both to custom and niche platforms neither crawler tags. Each is internally consistent; none is the single true number, so the honest answer to “how many online stores are there” is a range with a stated method attached, not one figure.

The Bottom Line
There is no single correct answer to how many online stores exist. Summing BuiltWith’s live crawl across the six leading platforms gives 18.18 million active storefronts today, and that number is a floor, since broader estimates that include every custom and niche platform reach as high as 30.7 million. What is consistent across every source is that Shopify and WooCommerce dominate by raw count, retention rates differ by a factor of three across platforms, and the United States hosts roughly half of all detectable e-commerce domains. Whatever platform a store runs on, the legal groundwork does not change with the count: a plain-language terms and conditions agreement that sets out payment, shipping, and dispute terms is worth having in place before the first sale, not after the first dispute.
