Microsoft Unveils AI Agent Commerce Infrastructure: Publisher Marketplace, Merchant Protocols, and Ad Tools

Gate News message, April 22 — Microsoft’s AI monetization vice president Tim Frank announced a suite of commercial infrastructure updates designed for the “agentic web” era, enabling publishers, merchants, and advertisers to remain discoverable and tradable as AI agents make purchasing decisions on behalf of users.

The initiative spans three core components. First, the Publisher Content Marketplace (PCM) expands Microsoft’s existing program, compensating publishers when their paid content is cited by AI platforms. PCM covers maps, product catalogs, news, and health information, moving from one-time licensing agreements to continuous marketplace-based transactions. Copilot serves as the initial demand partner, with negotiations ongoing with other AI platforms for integration.

Second, Microsoft launched the Universal Commerce Protocol (UCP) data source in Merchant Center—an open standard developed by Google, Shopify, and others—enabling AI agents to read structured product information directly. Shopify’s Global Catalog now integrates with Copilot, making products from over 500,000 merchants discoverable and transactable. Microsoft reported that top Shopify merchants saw approximately 90% growth in exposure share within Copilot. Copilot Checkout expanded to mobile and now supports loyalty programs from retailers including Target.

Third, Microsoft introduced expanded AI visibility tools and new advertising capabilities. Microsoft Clarity’s AI Visibility feature now shows brands how frequently their web pages are cited in AI responses, competitive benchmarking, and content gap recommendations. New offerings include AI Max search ads (beta launching in May), Offer Highlights (displaying product benefits in Copilot conversations), and Audience generation (using natural language to auto-generate audience targeting). Microsoft emphasized it will not take transaction fees, charging only for technical services at competitive rates. Frank noted Microsoft’s 51-year history as an enterprise service provider, with no conflicting incentive to compete with platform customers.
