The Agentic Commerce Report

Microsoft launched Copilot Checkout ¹ in the first full trading week of 2026, integrating payment processing directly into the Copilot assistant interface. The feature supports cards, digital wallets, and bank transfer, and uses Microsoft’s existing identity infrastructure for authentication. Google simultaneously announced the Universal Commerce Protocol (UCP) ² at the National Retail Federation annual conference, a specification for agent-to-retailer communication covering product queries, cart operations, and checkout initiation.

Copilot Checkout draws on a pre-authorisation model where users configure spending parameters before agent sessions begin. UCP uses a JSON-LD message schema and launched with endorsement from several retail technology vendors; Google framed it as complementary to its existing merchant feed infrastructure rather than a replacement.

Both events occurred in the same week for the first time since Stripe’s Commerce Suite launch and the Linux Foundation AAIF formation in December ³⁴. Microsoft’s Copilot Checkout brings a fourth major technology platform — alongside ChatGPT, Amazon Rufus ⁵, and Perplexity ⁶ — into the live consumer deployment category.

UCP’s JSON-LD approach differs from the API-first designs of Visa TAP ⁷ and Google AP2 ⁸; it targets the retail integration layer rather than the payment network layer. The first two weeks of 2026 produced two tracked events spanning both Payments and Standards lanes simultaneously.
