THE BUSINESS CASE / SOURCES & CONTEXT
The opportunity deserves attention. The investment still needs a business case grounded in your store, your customers and your platform.
McKinsey’s October 2025 scenario uses projected adoption and merchant-readiness assumptions. It excludes services and B2B.
A directional estimate of commerce volume. It is not a market capitalization, a current market measurement or a forecast of your store’s sales.
Adobe measures people clicking through from AI tools. Its October 2026 report draws on U.S. retail web activity.
A change in acquisition behavior, not a count of autonomous orders. The report does not establish that protocol adoption causes sales growth, or state AI referrals’ share of total traffic.
WHAT THIS MEANS FOR YOUR BUSINESS
Look at how your products are discovered, which customers use AI-assisted journeys and what your platform already supports.
Agree whether the first objective is discovery, catalogue access or a supported commerce action. Select evidence that would make the work useful.
Track implementation quality and technical compatibility separately from traffic, conversion and revenue. Review both before expanding the scope.
THE PROTOCOL LANDSCAPE
These examples explain the landscape.
Your architecture determines which are relevant.
They are not a checklist every merchant must implement.
Catalogues, carts, checkout and order interactions through a common interface.
Interfaces for commerce between agents and merchants, with versioned requirements.
Signed mandates help establish the user’s intent and authority for a payment.
Communication and task coordination across agents. It is not itself a checkout standard.
UCP’s 2026 release history includes new capability versioning and payment-related changes. Updates can affect an existing integration’s behavior and compatibility.
