CMS market share in 2026: the latest comparable figures
The figures below come from W3Techs’ historical CMS market-share series, ending September 13, 2026. The denominator is websites with a detectable CMS in W3Techs’ surveyed relevant-web sample.

What percentage of websites use WordPress?
The answer depends on the denominator. In W3Techs’ historical series, WordPress represented 58.8% of websites with a detectable CMS on September 13, 2026. A separate W3Techs home-page snapshot, observed with an August 1, 2026 comparison baseline, put WordPress at 40.2% of all websites measured and 58.7% of websites using a CMS.
The all-websites figure includes sites for which no CMS was detected; the CMS-share figure considers only sites using a detected CMS. They answer different questions and should not be treated as competing estimates. The home-page snapshot is not the same date or series endpoint as the September 13 historical trend figure.
Is WordPress losing market share?
In W3Techs’ yearly series, yes: WordPress’ share among CMS-using websites declined from 62.0% at the start of 2025 to 58.8% on September 13, 2026. This is a change in market share, not evidence that the total number of WordPress sites fell by the same percentage or that sites necessarily migrated away.
The trend differs by platform. Shopify rose from 6.7% to 7.8%, and Wix from 4.6% to 6.2%, over the same start-of-2025-to-September-13-2026 comparison. Joomla declined from 2.2% to 1.6%, while Drupal moved from 1.3% to 0.9%.

All entries are shares among CMS-using websites in W3Techs’ yearly trend series; the endpoints are the start of 2025 and September 13, 2026. These are percentage-point changes in share, not percentage changes in the total number of sites.
How to interpret W3Techs’ CMS statistics
W3Techs describes its sample as well over 20 million relevant websites. Its methodology excludes sites without useful content and sites that are essentially duplicates, examines technologies at the website level rather than counting individual pages, and does not count subdomains as separate websites. W3Techs says, “Our reports are updated daily.”
That cadence makes the date important: a live snapshot and a historical-series endpoint can differ even when they are close together. The August 1, 2026 baseline shown on the W3Techs home snapshot and the September 13, 2026 historical trend endpoint should remain distinct. The figures describe detected technology in W3Techs’ defined sample; they are not a complete count of every site and should not be combined with another source’s percentages unless its sample and method are compatible.

Market share is useful for understanding how commonly a CMS appears in a particular measured sample. It does not establish which platform is best for a specific site, nor does it directly measure ease of use, cost, security, customization, or suitability for a business.
- For an online store, compare ecommerce features and operating needs rather than relying on popularity alone.
- For a highly customized site, consider the control and development work each platform permits.
- Compare hosted and self-managed operation, including who handles infrastructure and ongoing maintenance.
- For a migration, account for content transfer, integrations, redesign work, and long-term maintenance burden.
Those are selection factors for an individual project, not outcomes measured by the W3Techs market-share data.
