Where WordPress Stands in 2026

When you look at WordPress market share trends over the past decade, one thing is clear: no CMS has come close to matching its scale. As of mid-2026, WordPress powers roughly 43% of all websites on the internet and holds approximately 60–63% of the known CMS market — meaning, of all sites running on an identifiable content management system, nearly two-thirds are on WordPress. That’s not a prediction. That’s the current state of the web.

But the story is more nuanced than a single headline number. Market share is shifting at the edges, developer sentiment is evolving, and new pressures from AI-generated sites and no-code platforms are reshaping what dominance actually means going forward.

How WordPress Reached This Level of Adoption

WordPress started in 2003 as a blogging tool. By 2010, it had pivoted into a full CMS. By 2015, it crossed the 25% market share threshold for all websites. That trajectory wasn’t accidental — it was driven by three compounding advantages:

• Open-source licensing: No vendor lock-in, no per-seat costs, no platform fees. Anyone can download, modify, and redistribute WordPress freely.
• Plugin and theme ecosystem: Over 59,000 plugins in the official repository as of 2026, covering everything from e-commerce to CRM integrations. This ecosystem depth is nearly impossible for competitors to replicate quickly.
• Developer network effects: The more developers learned WordPress, the more agencies offered it, the more clients requested it. That reinforcing loop has run for 20+ years.

According to data tracked by Wikipedia’s WordPress article and corroborated by multiple CMS trackers, WordPress crossed 40% of all websites around 2021 and has hovered between 43–44% since then — suggesting the growth curve has flattened, but not reversed.

Where the Market Share Numbers Get Complicated

Not all data sources agree, and that matters when interpreting WordPress market share trends correctly. The discrepancy comes down to what’s being measured:

All websites vs. top websites

WordPress holds ~43% of all websites globally, but its share of the top 1 million websites is slightly lower — closer to 33–36% depending on the tracking source. That gap reflects a real phenomenon: WordPress is disproportionately used by small and mid-sized sites. Enterprise deployments tend to skew toward headless setups, custom CMSs, or enterprise platforms like Adobe Experience Manager and Sitecore.

CMS market share vs. total web share

When analysts report «63% of the CMS market,» they’re only counting sites that use a detectable CMS. A significant portion of the web runs on custom-built stacks, static site generators, or frameworks like Next.js where no CMS is identifiable. WordPress’s dominance within the CMS segment is real — but it’s a smaller pond than «the entire internet.»

The shrinkage signal worth watching

Data from GravityKit and joost.blog shows WordPress peaked at roughly 35.76% of all tracked websites in July 2022 and has eased to approximately 33.2% by April 2026. That’s a 2.5 percentage point drop over four years. Slow — but directionally meaningful. The platforms gaining ground? Primarily Wix and Squarespace, which have improved significantly on ease-of-use and performance.

Key Trends Reshaping WordPress Adoption

Market share numbers are a snapshot. The more useful question is: what forces are actively pushing and pulling that number?

The headless WordPress shift

More enterprise teams are decoupling the WordPress backend (where content lives) from the frontend (where it’s displayed). This headless architecture — often paired with React or Next.js — keeps WordPress in the stack but makes it «invisible» to market share trackers scanning for WordPress themes. In other words, some of the apparent market share loss may be WordPress going headless rather than going away.

AI-generated websites

2025 and 2026 have seen a surge in AI website builders — tools that generate entire sites from a text prompt. Many of these don’t use WordPress at all. If the total number of websites on the internet grows rapidly due to AI generation, WordPress’s percentage share could decline even if its absolute number of installs keeps growing. This is a dilution effect, not a displacement effect.

WooCommerce and e-commerce growth

WooCommerce remains the most installed e-commerce platform globally, running on an estimated 3.6–4% of the top 1 million websites. As reported by WooCommerce’s Wikipedia entry, it consistently outpaces Shopify in total store count — though Shopify leads in gross merchandise value for high-volume stores. For agencies building mid-market stores, WooCommerce’s flexibility within WordPress remains a primary driver of continued adoption.

Security perception

WordPress’s popularity makes it a high-value target. Over 90% of CMS-based website hacks involve WordPress — not because it’s inherently insecure, but because of its scale and the volume of outdated, poorly maintained installs. This reputation creates drag on adoption in regulated industries (finance, healthcare) where security posture carries procurement weight.

What This Means for Agencies Building on WordPress

For digital agencies, the WordPress market share trends signal something specific: the platform isn’t dying, but the way it’s used is maturing. The era of «install a theme, add some plugins, ship the site» is giving way to more deliberate, architecture-conscious builds — especially for clients with real performance and integration requirements.

That shift creates opportunity. Agencies that can deliver custom WordPress builds with clean architecture, handle API integrations properly, and manage performance at scale will differentiate meaningfully from commodity WordPress shops. Clients are getting more sophisticated. They’ve seen enough slow, plugin-bloated sites to start asking better questions before they sign a contract.

The data from CMS adoption research consistently shows that WordPress retention is highest among organizations with dedicated technical resources managing the platform — whether in-house or through an agency partner. The platforms eating into WordPress’s share tend to win with simplicity, not capability. That’s a useful frame: WordPress doesn’t need to be simpler. It needs to be better managed.

Frequently Asked Questions

Is WordPress losing market share in 2026?

Marginally, yes — from a peak of ~35.76% of all tracked websites in 2022 to ~33.2% in April 2026. Within the known CMS market, it still holds 60–63%. The shift is real but slow, and partly explained by headless implementations that obscure WordPress presence in tracking data.

What CMS platforms are growing fastest?

Wix and Squarespace have posted the most consistent gains in recent years, primarily in the small business and personal site segment. Shopify continues to grow in e-commerce. None of these are displacing WordPress at the mid-market or enterprise level in significant volume.

Does WordPress market share matter for agencies?

It matters as a demand signal. A platform used by 43% of the internet sustains a massive talent pool, plugin ecosystem, and client familiarity. Even a gradual decline in percentage share doesn’t translate to declining demand for skilled WordPress development in the near term — the installed base is simply too large.

Will WordPress still be relevant in five years?

Almost certainly. The open-source nature, the size of the contributor community, and the depth of the plugin ecosystem create a resilience that proprietary platforms lack. The more relevant question is how WordPress is used — and the trend is clearly toward more custom, performance-focused implementations rather than out-of-the-box installs.
