PubMatic Inc. (NASDAQ:PUBM) is one of the best AI stocks with huge upside potential. On March 12, PubMatic and Optable partnered to integrate privacy-safe, first-party audience data into automated media buying workflows via PubMatic’s AgenticOS. This collaboration allows Optable’s ‘Audience Agent’ to work within PubMatic’s AI-driven infrastructure, enabling advertisers to discover and activate high-value audience signals from premium publishers autonomously.

By using agent-to-agent communication, the partnership facilitates complex audience planning and real-time bidding without the need to transfer or expose sensitive underlying data. The integration focuses on enhancing addressability and yield for publishers while simplifying the procurement process for buyers. Publishers can surface custom audience segments to advertisers through Optable’s platform, which then connects directly to PubMatic Activate for immediate execution.

This streamlined approach allows participants to tap into agentic demand without requiring significant changes to their existing technical infrastructure. This partnership serves as a real-world application of the Advertising Context Protocol/AdCP, highlighting a shift toward decentralized, interoperable AI collaboration in advertising. By moving away from centralized data systems, Optable and PubMatic Inc. (NASDAQ:PUBM) are establishing a framework where privacy-governed intelligence powers programmatic execution on the open web.

PubMatic Inc. (NASDAQ:PUBM) is a technology company that provides a cloud infrastructure platform that enables real-time programmatic advertising transactions for digital content creators, advertisers, agencies, agency trading desks, and demand side platforms worldwide.
