Agentic commerce is the practice of using AI agents to research, compare, negotiate, and complete purchases on behalf of consumers or businesses. Unlike traditional ecommerce where humans browse and click through product pages, agentic commerce systems autonomously evaluate options, process structured product data, and execute transactions based on predefined preferences and constraints. The term gained traction in 2025-2026 as major platforms launched commerce-specific AI agent protocols: OpenAI's Agentic Commerce Protocol (ACP), Google's Universal Checkout Protocol (UCP), Visa's Intelligent Commerce Connect, and Stripe's Agentic Toolkit. McKinsey projects agentic commerce could orchestrate up to $1 trillion in US B2C retail revenue by 2030. For brands and retailers, agentic commerce changes what matters on the product page. When an AI agent evaluates a product, it needs structured, machine-readable content, not just visually appealing images. Product data quality, schema markup, and comprehensive content coverage become direct revenue drivers.
