WordCamp US Reports 425 Contributor Day Participants and Large Publisher Migrations

Contributor Day at WordCamp US 2026 brought together 425 participants, including 29 first-time contributors, who formed 26 task-focused teams. An official recap published by WordPress on 20 August 2026 says contributors closed tickets, opened and shipped pull requests, reviewed themes for accessibility, and worked on documentation, testing, and contribution tools. The recap separately reports that more than 1,100 people registered for the wider event rather than presenting that figure as verified attendance.

The recap also highlights two publisher migrations presented during Showcase Day: Daily Kos from a custom CMS and The Ankler from Substack. The cases extend the event record beyond participation figures by documenting migration requirements around content, community data, memberships, and editorial control. For Drupal readers, they provide comparison points for organisations evaluating open-source publishing platforms without establishing a direct shift between Drupal and WordPress.

A WordCamp US session by XWP chief technology officer Ben Greeley and Daily Kos chief technology officer Allison McHenry described moving 1.5 million posts, 2.7 million users, and 88 million comments off a custom-built CMS, with more than 500 community members participating in a public beta. Daily Kos had already announced that its WordPress version was scheduled to launch on 15 April 2026 and said published stories, comments, recommendations, community groups, follower records, images, and actively used tags were among the material being migrated. An XWP case study says the resulting platform uses WordPress VIP with BuddyPress for community features, Viafoura for comments, and PostHog for analytics and experimentation.

XWP chief delivery officer Nicola Catton's WordCamp US session says The Ankler moved 15 newsletters from Substack to WordPress in April 2026. Catton described tens of thousands of posts and media files, thousands of rebuilt paywall boundaries, and the mapping of one Substack paid tier to six Passport audiences. Axios independently reported in April that The Ankler was leaving Substack for Passport as the publication expanded to 15 newsletters alongside podcasts, video, and live events.

For Drupal agencies and publishing teams, the cases offer practical comparison points rather than evidence of a direct Drupal-to-WordPress migration trend. The Daily Kos case highlights archive scale, user data, community features, and public beta testing, while The Ankler case highlights paywall reconstruction, audience segmentation, and subscriber-data control. Those requirements are relevant to teams assessing how an open-source CMS should support complex publishing migrations.
