Agentic CommerceWhy this site, why now
In fifteen months, online commerce acquired an entirely new infrastructure: a connection protocol that became a de facto standard (MCP, late 2024), a conversational checkout deployed at ChatGPT's scale (ACP, September 2025), a mandate-based payment layer (AP2, September 2025), and an open standard backed by an unprecedented coalition of retailers and payment players (UCP, January 2026). Each of these milestones has its detailed explanation on this site.
What was missing, in our view: a reference that holds these threads together — the concepts, the protocols, and above all their translation into concrete work for merchants. That's this site's ambition, summarised in its reference page and its 20-point audit.
Where agentic commerce stands in summer 2026
- The surfaces are open. People have been buying in ChatGPT since autumn 2025, and in Google's AI Mode and Gemini since January 2026 — the United States first, with geographic expansion starting in spring (Canada, Australia, the UK).
- Standards are converging. Capability negotiation, product feeds, delegated payment: UCP and ACP adopted the same concepts across their versions, and both can build on MCP. The “protocol war” increasingly looks like a stack of compatible layers.
- Continental Europe is waiting its turn — with no official date, but clear signals, including Carrefour's adoption of UCP at launch. Technical preparation, however, doesn't wait: it's identical whatever the market.
- B2B remains the ground to take. Current deployments are overwhelmingly B2C; B2B mechanics — per-account pricing, replenishment, mandates — are exactly what the protocols are starting to handle. Our B2B guide explains why we see the real growth lever there.
What this watch will cover
Every week: changes across the four protocols (their specifications move every quarter), platform and buying-surface announcements, geographic rollouts — with particular attention to anything touching Europe and B2B. See you next week.
