E-commerce Platform Market Share Report 2026: 84,000 Stores Analysed

The Headline: Shopify Powers 42.6% of E-commerce

Shopify (including Shopify Plus) powers 42.6% of e-commerce stores in 2026 — up from 31.8% in 2022 (+10.8pp). WooCommerce holds 24.6% (down 7.8pp). Magento (Adobe Commerce + Open Source) has dropped to 8.4% (down from 18.6% — a 10.2pp four-year loss). Custom/headless powers 9.4% of stores but 38.4% of stores doing >$32M revenue.

Across our Q1 2026 crawl of 1,000,000 domains (cross-referenced with 180,000 Google Business Profiles), we identified ~84,000 e-commerce stores. The story is consolidation around three poles: Shopify dominates volume, custom/headless dominates value, and WooCommerce dominates the long tail.

The 10.8pp Shopify gain is the largest single-platform e-commerce share gain we have measured in any four-year period. The 10.2pp Magento loss is the largest single-platform decline. The Magento → Shopify migration alone accounts for 4,210 of the ~17,000 e-commerce platform moves we tracked between 2024 and 2026.

The custom / headless layer is small in store count (9.4%) but large in revenue. Stores doing >$32M revenue are 38.4% custom or headless — the platform mix at the high end is fundamentally different from the mid-market mix.

E-commerce Platform Share (2026 Master Table)

Across 84,000 e-commerce stores: Shopify 42.6% (Shopify Plus 6.4% within), WooCommerce 24.6%, custom/headless 9.4%, Magento 8.4%, Squarespace Commerce 4.2%, Wix Stores 3.8%, BigCommerce 2.8%, Ecwid 1.6%, others 2.6%. Among $635K+ revenue stores, the top 3 are Shopify (38.4%), Magento (24.8%), and custom (18.4%).

By store count (all e-com)

By $635K+ revenue stores

Source: Visionary 1M-Domain Crawl, e-com subset Q1 2026, with revenue estimates from cross-reference to first-party tracking dataset.

The two tables together tell the right story: Shopify wins the count, but the count is dominated by smaller stores. At $635K+ revenue scale, Magento and custom/headless still compete credibly.

Shopify (and Shopify Plus): The Standard

Shopify (standard + Plus) powers 42.6% of e-commerce in 2026. Shopify standard alone holds 36.2%; Shopify Plus 6.4%. Net Shopify gain in 24 months: +9,840 stores. The Shopify app stack averages 12.4 apps installed per store; Klaviyo is the most-installed at 42.4%.

Shopify's growth has been the structural narrative of e-commerce for four years. The platform has gained share consistently every quarter for 16+ consecutive quarters and is now the dominant e-commerce platform across all but the largest enterprise tier.

Source: Visionary 1M-Domain Crawl, longitudinal e-com share dataset.

Shopify's structural advantages: zero infrastructure burden, strong app ecosystem (8,000+ apps), best-in-class checkout, modern theme architecture (Online Store 2.0 + Hydrogen), and a mature partner ecosystem. Shopify Plus stores average 24.6% higher conversion rate than Shopify standard, mostly due to better hosting performance, custom checkout extensibility, and dedicated launch engineering support.

Most-installed Shopify apps: Klaviyo 42.4%, Judge.me 28.4%, Loox 18.6%, ReConvert 12.4%, Shogun 9.8%, Recharge 8.4%, Smile.io 6.8%, Bold Bundles 6.4%, Searchanise 5.4%, LangShop 4.2%.

WooCommerce: The Micro-Business E-commerce Layer

WooCommerce powers 24.6% of e-commerce in 2026, down from 32.4% in 2022. Strongest in micro-business: WooCommerce share is 48.4% of stores doing under $127K revenue. Average WooCommerce store has 28.6 plugins installed and a 3.8s LCP — the slowest performance of any major e-com platform except Magento.

Source: Visionary 1M-Domain Crawl, e-com subset Q1 2026.

WooCommerce's structural challenges at scale: page speed, plugin sprawl (mean 28.6 plugins creates security and update overhead), and reliance on shared/managed WordPress hosts that struggle with traffic spikes. Above $2.54M revenue, very few stores stay on stock WooCommerce; most either re-platform to Shopify or move to a heavily-customised stack.

Magento (Adobe Commerce): The Enterprise Holdout

Magento powers 8.4% of e-commerce in 2026, down from 18.6% in 2022 — a 10.2 percentage-point loss. Magento retains share only at the high end: 22.4% of stores with $6.35M+ revenue and 28.2% of stores in the $318-$635 AOV bracket. Magento store count fell -5,070 in the trailing 24 months.

Drivers: end-of-life pressure on Magento 1, aggressive Shopify Plus migration incentives, and rising TCO of Adobe Commerce Cloud relative to Shopify Plus.

Source: Visionary 1M-Domain Crawl, e-com subset Q1 2022 vs Q1 2026.

The Magento performance picture is the worst of any major e-com platform: median LCP 4.2s, INP 312ms, only 22.6% of pages with all CWV "Good." Mean conversion rate 1.84%. The performance gap vs Shopify Hydrogen is large enough that the platform-move-alone conversion uplift is typically 35-50%.

BigCommerce, Squarespace Commerce, Wix Stores: Niche Players

BigCommerce holds 2.8% of e-commerce (stable since 2022), Squarespace Commerce 4.2% (+0.8pp), Wix Stores 3.8% (+0.8pp). BigCommerce concentrates in B2B-flavoured e-commerce; Squarespace and Wix are micro-business creative-brand platforms. None of the three competes credibly above $1.27M revenue.

Source: Visionary 1M-Domain Crawl + 2.4M-Session Tracking Dataset.

BigCommerce's position is structurally stuck — positioned as a Shopify alternative but lacking Shopify's app ecosystem advantage. Squarespace Commerce wins on design quality and works credibly for low-product-count brands (under 50 SKUs). Wix Stores wins on price for very small operators; above 100 SKUs or $13K monthly revenue, the platform hits its ceiling.

Custom & Headless E-commerce: 9.4% but 38% of $32M+ Stores

Custom-built and headless e-commerce powers 9.4% of stores but 38.4% of stores doing >$32M revenue. Top headless front-ends: Next.js 56.4%, Astro 14.2%, Nuxt 8.4%. Top headless commerce backends: Shopify Hydrogen, BigCommerce headless, custom + Stripe, commercetools.

Source: Visionary 1M-Domain Crawl, e-com subset Q1 2026.

The build cost (typical headless e-com build $73K-$305K) only justifies itself above ~$2.54M revenue. Performance is genuinely best-in-class: median custom/headless LCP 1.6s, INP 124ms, 84.6% of pages all-CWV-Good. Conversion rate median 3.84% — partly selection bias, but partly a real performance compounding effect.

Share by AOV Bracket (Where Each Platform Wins)

By AOV bracket, the dominant platforms are: <$25 Shopify (54.2%), $25-64 Shopify (48.4%), $64-127 Shopify (44.6%), $127-318 Shopify (38.4%) with Magento close at 24.6%, $318-635 Magento (28.2%) edges Shopify Plus (28.4%), $635+ custom/headless (44.6%) dominates.

Source: Visionary 1M-Domain Crawl, e-com AOV bracket analysis Q1 2026.

Low AOV is dominated by Shopify (mass-market commerce, high transaction volume, low complexity per order). High AOV is dominated by custom/headless and Magento (low transaction volume, high per-order complexity, often B2B-flavoured or considered-purchase journeys). The $127-$318 AOV bracket is where most replatforming decisions are made.

E-commerce Migration Patterns

Top e-commerce migration paths in the trailing 24 months: Magento → Shopify (4,210 stores), WooCommerce → Shopify (2,610), WordPress → Shopify (1,840), BigCommerce → Shopify (620). Net Shopify gain: +9,840 stores. Net Magento loss: -5,070. The 24-month migration volume represents ~20% of the e-com market churning platforms.

Source: Visionary 1M-Domain Crawl, platform-detection delta Q1 2024 vs Q1 2026.

Three macro patterns: (1) Magento exodus — 5,070 net stores lost since 2024, mostly to Shopify; (2) WooCommerce thinning — net 2,790 lost, almost entirely to Shopify; (3) Custom/headless scaling — small absolute numbers but high-value migrations off Shopify Plus or Magento toward control + performance.

Performance by Platform: Speed, CWV, Conversion

Median e-commerce LCP by platform: custom/headless 1.6s, Shopify Hydrogen 1.8s, Shopify Dawn 2.4s, BigCommerce 2.8s, Squarespace 2.8s, Wix 3.4s, WooCommerce 3.8s, Magento 4.2s. Median conversion rate follows the same hierarchy: 3.84% custom, 3.42% Shopify Hydrogen, 1.84% Magento.

Source: Visionary 50K Ranking-Page Analysis 2026 + 2.4M-Session Tracking Dataset 2026.

The 2x conversion-rate gap between the fastest and slowest e-com platforms is the single largest non-pricing-related ROI lever in the platform decision. Median AOV by platform reveals the inverse: Magento has the highest AOV ($181.10) because its remaining install base is high-value enterprise stores; Wix and WooCommerce have the lowest AOV because they skew small.

Revenue per Platform (GMV Estimates)

Estimated 2025 GMV by platform: Shopify $31.2bn, custom/headless $23.4bn, Magento $18bn, WooCommerce $10.9bn, BigCommerce $3bn, others $5.3bn. Magento and custom/headless punch well above their store-count share because they dominate large-AOV stores.

Source: Visionary 2026 e-com GMV estimate, extrapolated from 84,000-store sample × mean platform revenue cross-validated against first-party tracking dataset.

Custom/headless is 9.4% of stores but ~25% of e-com GMV. Magento is 8.4% of stores but ~20% of GMV. Shopify is 42.6% of stores and ~34% of GMV — the platform's mass appeal at the SMB level dilutes its GMV share relative to its store-count share.

Plugin / App Ecosystem Sizes

The largest e-commerce app ecosystems by mean installs per store: Magento 38.4 modules, WooCommerce 28.6 plugins, Shopify 12.4 apps, BigCommerce 8.2 apps. Top apps: Klaviyo (42.4% of Shopify), Yoast SEO (62.4% of WooCommerce), Mageplaza One Step Checkout (Magento).

Source: Visionary 1M-Domain Crawl plugin/app detection.

Higher app/plugin counts are not better — they correlate negatively with performance. The Shopify ecosystem is smaller per-store but more curated; each app tends to be more business-critical. The Klaviyo dominance on Shopify (42.4%) is the largest single-app concentration in any e-commerce ecosystem.

Total Cost of Ownership by Platform (2026)

Mean annual TCO for a $635K-revenue store: Shopify $6,147, Squarespace Commerce $1,219, WooCommerce $8,153, BigCommerce $10,668, Magento Open Source $23,622, Shopify Plus $36,068, Adobe Commerce Cloud $79,248, custom/headless $106,934.

Source: Visionary 2026 e-com TCO model, derived from ~64 TCO benchmarking exercises 2024-26.

TCO components included: platform fees, hosting, mandatory plugins/apps, theme/template costs, and dev maintenance retainer. Excluded: marketing spend, payment processing fees (Stripe / PayPal / Klarna), CRM, ERP integration, custom feature builds.

The TCO progression is non-linear. Shopify standard is the price-leader for self-serve mid-market; Shopify Plus becomes the right answer above ~$2.54M revenue. Adobe Commerce Cloud is enterprise-only justified. Custom/headless TCO is the highest by some margin but unlocks unique performance and design capability.

Deep Analysis: How To Read The 2026 Ecommerce Platform Market Share Numbers

Platform market-share data is one of those datasets that looks straightforward until you try to use it to make a decision. The headline league table — Shopify, WooCommerce, Magento/Adobe Commerce, BigCommerce, Wix, Squarespace, headless — is drawn from the population of live stores, but the population that matters to a founder or CMO is a much narrower one: stores in their revenue band, their vertical and their operating market. Shopify's dominant share of new store starts in 2025–2026 is real, but it is heavily weighted by DTC brands under £2m revenue. Adobe Commerce still runs a disproportionate share of £20m+ retailers because migration cost, catalogue complexity and ERP integration make platform switches expensive. The right question is never "which platform has the largest market share?" — it is "which platform is winning in the segment I am actually in?"

Shopify's advantage in 2026 is no longer about ease of setup — every serious platform is now good enough on that dimension. The moat is the ecosystem: Hydrogen and Oxygen for headless, Shop Pay's conversion uplift, Shopify Audiences feeding lookalikes back into Meta and Google, Markets for cross-border, and a Shopify App Store that has become the single largest distribution channel for ecommerce tooling. For a growing brand, the compounding cost of leaving that ecosystem is now higher than the compounding cost of paying Shopify Plus fees. That is why churn out of Shopify Plus above £5m revenue has fallen sharply since 2023, even as competitors have made noise about winning enterprise deals. The migrations that do happen are usually to headless architectures where Shopify remains the commerce engine — a shift the market-share tables often mis-classify as "leaving Shopify".

WooCommerce's market share is a genuine outlier that deserves careful interpretation. It looks huge because it powers a very large tail of small, low-revenue and often abandoned stores — the flip side of being a free WordPress plugin. Within active, revenue-generating UK ecommerce, WooCommerce's share is meaningfully smaller than the raw numbers suggest, and its share of new merchant starts has been declining for four consecutive years. The stores where WooCommerce remains a strong choice in 2026 are content-first businesses (publishers, membership sites, course businesses) where WordPress's editorial capability is the primary asset and commerce is bolted on. For a pure retail play, choosing WooCommerce today typically means underestimating the total cost of ownership: hosting, plugin licensing, developer time, security patching, and the compound tax of maintaining a stack that no single vendor owns end-to-end.

Adobe Commerce (Magento) has stabilised at the top of the mid-market and lower enterprise, but the story is one of consolidation rather than growth. Adobe's pricing has pushed a segment of former Magento merchants toward Shopify Plus, and a segment toward composable commerce architectures using Commercetools, BigCommerce or Shopify as the backend. What remains on Adobe Commerce tends to be complex B2B and B2B2C catalogues where multi-store, tiered pricing, complex tax handling and deep ERP integration justify the licence. For a UK retailer deciding between Adobe Commerce and Shopify Plus in 2026, the honest answer is that the total cost of ownership is now roughly comparable at similar revenue bands, so the decision should be made on team capability, integration surface area and vertical fit rather than headline platform fees.

Headless commerce has moved from experimental to mainstream in a specific segment: brands doing more than £3m revenue with an in-house engineering team, or agencies that can operate a Next.js / Remix / Astro storefront on their behalf. The market-share data understates headless adoption because most trackers classify the visible commerce backend (Shopify, BigCommerce, Commercetools) rather than the storefront layer. In practice, roughly one in three brands over £10m in UK ecommerce now runs a headless or hybrid storefront, and that proportion is climbing. The rational case for headless is not performance — modern themes on Shopify and BigCommerce are fast enough — it is the ability to ship product content, SEO changes and A/B tests without waiting for a theme deployment. For teams that treat the storefront as a product, headless pays back. For teams that treat it as a website, it usually does not.

Wix and Squarespace occupy a real segment: sole traders, service businesses with light ecommerce, and content-led brands where commerce is a secondary revenue line. Neither is a serious platform for retail businesses expecting to scale past £500k revenue, and both suffer from limitations on catalogue depth, feed export quality (which hurts Google Shopping performance), and headless flexibility. Their market-share growth is a signal of ecommerce broadening across the population, not a signal that serious operators are choosing them over Shopify. If you are on Wix or Squarespace and revenue is growing, the migration to Shopify or a competitor should be planned before you hit the ceiling — migrations under duress are always more expensive than migrations by choice.

The 2026 platform decision framework is narrower than the market-share tables suggest. For a new UK brand under £2m revenue with standard retail requirements, Shopify is the default and the burden of proof sits on any alternative. For a growing brand between £2m and £10m, the choice is Shopify Plus versus a headless architecture on Shopify's backend versus BigCommerce Enterprise — with team capability being the deciding variable. For a complex B2B or multi-region enterprise above £20m, Adobe Commerce and composable stacks (Commercetools, Elastic Path, Shopify + third-party) become viable candidates, and the choice is driven by integration surface area rather than platform fees. Everyone else is optimising the wrong variable. The teams pulling ahead in the data on this page are not the ones on the "best" platform; they are the ones whose platform choice matches the revenue stage, catalogue complexity and team capability they actually have.
