WordPress Powers 41% of All Websites
Not 41% of CMS sites. 41.5% of all websites on the entire internet. WordPress alone — a single PHP application — runs something close to half the web.
The trajectory is worth being honest about. In January 2013, WordPress powered 17.4% of all websites. It roughly doubled over the following decade, peaked north of 43%, and has since eased back to 41.5% as site builders and headless stacks took a slice. It is no longer climbing. It is also, still, four out of every ten websites that exist.
The top three CMS platforms by market share — WordPress, Joomla, and Drupal — are all written in PHP. Combined, they represent the overwhelming majority of managed web content on the planet.
But this isn't just about WordPress the software. It's the WordPress economy: thousands of commercial plugins, thousands of premium themes, hosting companies optimized specifically for it, and agencies built entirely around the platform. PHP doesn't just power websites — it powers livelihoods.
