What is a CMS in 2026? Mark Demeny on AI, Content Supply Chains, and the Future of Content Management

2025 saw a lot of change across the CMS landscape, and AI was at the center of it. As the year wraps, we’re left asking: What is a CMS in 2026? How is its role transforming? And most importantly, how will it continue to deliver value? To answer these questions, we sit down with the ever-brilliant Mark Demeny, one of the leading minds in the content management space. Drawing on his deep resume of experience – from Sitecore to Optimizely to Uniform – Mark gives us a real-world perspective on what’s ahead in 2026 and beyond. Against a backdrop of AI disruption, new DX buzzwords, and shifting buyer expectations, Mark unpacks how the CMS is being reshaped by market forces. He examines it all through a composable lens, sharing some of his experience with the MACH Alliance and his work on the Open Data Model and its implications for composability, interoperability, and AI orchestration. Mark also explores recent challenges to the perception of CMS as AI offers an alternative to SaaS software. While this shift in choice is gaining traction, Mark reminds us of the importance of governance and trust when powering complex workloads – and why a proven CMS is still essential to the stack. In the second half, Mark explains how the future of CMS lies with the “content supply chain,” and how this will require new thinking for editors and operators in the age of AI. We also get a preview of a new book he’s co-writing with fellow CMS luminary Deane Barker, aimed at helping practitioners navigate this shift from traditional content management to AI-powered, system-level thinking. There are no crystal balls to tell us what’s ahead, but Mark is as close to prescient as we can get. If you’re buying, building, or rethinking your CMS and DX strategies next year, this is a must-listen episode. ------------------------------- Episode Runtime: 55:10 Highlights: • 00:00 – Intro • 04:59 – Mark Demeny • 06:07 – Legos as "stress therapy" and composable analogy • 09:58 – Redefining CMS • 18:06 – AI's impacy and the role of governance • 20:47 – Managing the "content supply chain" • 27:30 – The chaos of versions and variants • 33:47 – Friction and AI failure • 37:28 – The role of agents • 39:53 – The future of content roles and jobs • 49:05 – A new book with Deane Barker • 54:05 – Wrap up (Big thanks to Brian Kelly for composing and performing our amazing musical track)
