Optable and PubMatic Unite for Privacy-Safe Audience Activation
Optable and PubMatic announced a partnership integrating Optable’s Audience Agent into PubMatic AgenticOS. The integration lets buyers discover, build, analyze and activate privacy-safe, publisher-controlled first‑party audience signals across premium publishers without transferring underlying data. Activation runs through PubMatic Activate (a direct-to-supply media bidder) to enable real-time programmatic (RTB) execution. Both companies position the work as enabling interoperable agent-to-agent workflows and cite the Advertising Context Protocol (AdCP) as an early example of secure, privacy-focused collaboration. PubMatic and Optable say the integration aims to increase publisher addressability and yield while giving advertisers more direct access to high-value audience signals and faster campaign activation.
Integration connects agentic AI audience planning with real-time programmatic activation and demonstrates AdCP-based agent-to-agent workflows; relevant to publisher addressability and privacy-safe first-party data activation but is a vendor partnership rather than a major platform policy shift.

AI Agents Unlock Publisher First‑Party Data Monetization
Publisher-focused AI agents are being used in-market to automate audience curation and monetize first-party data. PubMatic and Optable are collaborating to integrate Optable’s sell-side audience agent with PubMatic’s buy-side agent via PubMatic’s AgenticOS framework, enabling end-to-end agentic programmatic workflows. Agentic solutions have moved beyond direct-sold deals into curated programmatic private marketplace (PMP) campaigns; PubMatic has completed more than 1,000 agentic direct deals and has run roughly 30 agentic programmatic campaigns, with the Optable integration powering about half of those. Publishers and ad networks (e.g., Mediavine, Livewire) say agentic curation can surface previously untapped first-party audiences at scale, improve discoverability without large sales teams, and attract incremental demand from buyers and agencies testing agentic AI activation paths.
PubMatic and Untapped Growth Partner for Agentic Media Buying
PubMatic and Untapped Growth announced a partnership that gives independent agencies direct integration into PubMatic’s AgenticOS. Member agencies in the Untapped Growth collective can deploy proprietary buyer agents inside AgenticOS to create and launch campaigns with access to PubMatic’s data partners, premium inventory (including 28 of the top 30 CTV streamers), and GPU-backed infrastructure. PubMatic says early AgenticOS campaigns have cut supply chain costs by 40–50%, delivered 40% more impressions at 30% lower eCPMs, sped campaign setup by 87% and reduced troubleshooting time by 70%. The workflow uses an LLM-powered natural-language interface for briefs, runs through PubMatic’s Activate direct bidder with MCP/AdCP protocol support, and provides real-time delivery signals inside agencies’ environments without additional intermediary integrations.
PubMatic Unveils Fast-Track OS for Agent-Based Advertising
PubMatic has launched an "Agentic OS," a Nvidia-accelerated operating system for agent-based programmatic advertising that aims to enable "Agent-to-Agent" workflows where specialised AI agents plan, execute, optimise and monitor campaigns autonomously. Early partners including WPP Media and MIQ will test agentic campaigns under real market conditions. The three-layer architecture (infrastructure, application/agentic functions, transaction layer) claims up to fivefold faster decisioning, sub-millisecond reaction times and fewer auction timeouts. Agentic functions operate via protocols such as the Ad Context Protocol (AdCP) and the Model Context Protocol (MCP) and automate planning, pacing, optimization, troubleshooting and measurement. PubMatic integrates Agentic OS with existing programmatic buying models (Programmatic Guaranteed, Private Marketplaces) and routes media via its Activate buying platform. PubMatic positions the approach as particularly relevant for complex environments like CTV, while noting adoption will depend on control, transparency and scalable governance in practice.
