PubMatic announced the launch of AgenticOS, an AI‑driven operating system that orchestrates autonomous, agent‑to‑agent advertising execution across premium digital inventory. The platform builds on the company’s existing AI infrastructure and is designed to let advertisers, agencies, and publishers plan, transact, and optimize campaigns in real time without manual intervention.

AgenticOS leverages NVIDIA‑accelerated computing and is embedded in PubMatic’s global infrastructure, enabling millions of ad transactions per second to be coordinated by intelligent agents. The system supports a full workflow—from natural‑language brief entry to continuous optimization—while maintaining brand‑safety guardrails and performance transparency for partners such as WPP Media, Butler/Till, and MiQ.

The launch follows a December 2025 pilot that saw Butler/Till and Geloso Beverage Group’s Clubtails run an agentic campaign on the platform, demonstrating the system’s ability to scale and deliver real‑time optimization. PubMatic’s Q3 2025 earnings showed a 5% year‑over‑year revenue decline, but the company maintained adjusted EBITDA profitability for the 38th consecutive quarter, driven by strong growth in connected‑TV, mobile‑app, and emerging inventory segments.

Management highlighted that the NVIDIA partnership has accelerated AI processing speeds by up to five times and reduced latency, positioning PubMatic to capture a larger share of high‑margin, AI‑driven streams. CFO comments emphasized that the company’s focus on high‑growth segments offsets headwinds in legacy display, and that the new platform will further strengthen its competitive advantage in the agentic advertising space.

The launch signals PubMatic’s commitment to leading the next generation of programmatic advertising and could reshape the industry’s approach to autonomous campaign management, positioning the company to capture higher‑margin revenue streams in connected‑TV, mobile‑app, and emerging inventory.
