Agentic Commerce: 1 Million Shops Promised, 30 Delivered

A year ago, OpenAI announced the Agentic Commerce Protocol and Instant Checkout, with over one million Shopify shops directly in ChatGPT. In the end, fewer than 30 merchants went live, and in March 2026 the whole thing was switched off. Time to take stock: is the online shop dead, is there only GEO instead of SEO now, and who is actually supposed to use this?

I go through the complete timeline, from the Model Context Protocol via ACP and Google's Universal Commerce Protocol to Meta's Muse and cart transfer, and look at what is left of the big bet on agentic commerce. Spoiler: in-chat checkout is practically dead, but AI as a discovery channel keeps growing. What that means for assortment data, feeds, architecture and your KPIs is the real topic.

The numbers in the video
Instant Checkout: over 1 million Shopify merchants announced, fewer than 30 live, switched off on 20 March 2026

92% of respondents reject fully automated purchasing (bevh, 40,000 respondents)
30% use AI chatbots for product research (CELUM, 1,000 respondents, Germany)
