This reference document compiles the announcements and analyses from NRF 2026 (National Retail Federation's Big Show), held January 11-13, 2026 in New York, gathering 40,000 visitors and 1,025 exhibitors from 100 countries.
The major announcement on January 11 was the launch by Sundar Pichai (CEO of Google) of the Universal Commerce Protocol (UCP), an open-source standard under the Apache 2.0 license enabling AI agents to discover, negotiate, and finalize purchases directly with retailer systems. Co-developed with Shopify, Walmart, Target, Etsy, and Wayfair, and backed by more than 60 organizations (Visa, Mastercard, PayPal, Sephora, Zalando), UCP adopts a layered architecture inspired by TCP/IP with four transports: REST API, Anthropic's MCP, Agent2Agent, and an embedded JSON-RPC protocol.
Carrefour positioned itself as the first major European food retailer to adopt UCP. Emmanuel Grenier confirmed the commitment to offer integrated purchase journeys within Google Search and Gemini. The Walmart-Google partnership illustrates the potential: real-time inventory, delivery within 30 minutes, automatic application of Walmart+ benefits.
The very next day, Stripe and commercetools announced the Agentic Commerce Suite (ACS), a competing protocol, with JD Sports as the first European retailer to adopt it. This early fragmentation between UCP and ACS recalls the early days of the web and raises a strategic question about the emergence of a dominant standard.
The document details the shift from SEO to AIO (Artificial Intelligence Optimization). JSON-LD schemas (Product, Offer, AggregateRating) become mandatory, and the concept of Answer Eligibility Engineering replaces traditional ranking.
Metrics confirm the acceleration: +693% in traffic via generative AI (Adobe), a 7x increase in traffic and 11x increase in AI orders (Shopify), 20% of retail sales generated by AI agents (Salesforce). However, only 24% of consumers trust AI to make purchases.
In-store retail media emerges as a major opportunity ($65-78 billion in 2025), while the supply chain shifts from "Just-in-Time" to "Just-in-Case" with Digital Product Passports anticipating EU regulations.
The document concludes that the challenge is no longer digitalization but the "agentification" of commerce. Retailers without agentic transformation risk structural disintermediation, as AI agents steer consumers toward technically integrated retailers.
