PubMatic's AgenticOS Gains Traction in Digital Advertising Landscape

In a recent press release dated April 27, 2026, PubMatic (NASDAQ: PUBM) announced a significant milestone in its AgenticOS platform, indicating a marked shift in the digital advertising landscape. Originally unveiled at CES in January 2026, AgenticOS has transitioned from experimental phases to a fully operational system, now supporting end-to-end autonomous agentic campaigns across various markets, including the United States, France, the Netherlands, Australia, and India.

The latest data shows that buyers are increasingly returning to scale additional campaigns using AgenticOS, validating improvements in operational efficiency and economic returns. The platform has seen notable engagement from independent agencies and global brands, with partners like Brkthru, Butler/Till, MiQ, and Untapped Growth leading the charge in adopting agentic workflows.

At the core of AgenticOS is artificial intelligence, which PubMatic claims is revolutionizing the digital advertising sector by bridging the gap between publisher supply and buyer demand. This integration allows for unprecedented efficiencies and performance enhancements in campaign management.

PubMatic has embedded AI throughout its platform, boasting over 1,000 AI-enabled deals and millions of dollars in transactions. Buyers have the flexibility to control their level of AI integration, from utilizing PubMatic Assistant’s chat-based interface to launching fully autonomous agentic campaigns tailored to their specific objectives.

Rajeev Goel, Co-Founder and CEO of PubMatic, emphasized the importance of agility in this evolving landscape. "The companies moving fastest are the ones with the agility and vision to make bold new moves,” he stated. He noted that independent agencies and mid-market brands are at the forefront of this agentic shift, driven by the potential for rapid, verifiable results.

Brkthru has emerged as a key strategic partner in the rollout of AgenticOS, managing media for over 1,000 brands and supporting 235 agencies across 25+ buying platforms. Tom Leone, Vice President of Media Services at Brkthru, highlighted early improvements in workflows, allowing their traders to focus more on strategy and client relationships rather than manual coordination.

The effectiveness of AgenticOS is underscored by successful outcomes from various independent agencies and advertisers. Currently, 30 live end-to-end agentic campaigns are operational globally, showcasing impressive returns. For instance, Butler/Till's campaign for Geloso Beverage Group achieved a reduction in buy-side fees by over 500%, delivered 40% more impressions than planned, and resulted in a 30% lower effective CPM.

In another example, a national advertiser's fully autonomous campaign across more than 800 publishers successfully optimized delivery, surpassing impression and view-through rate targets.

PubMatic's global reach continues to expand, with successful campaigns now active in the EMEA and APAC regions. Noteworthy achievements include France's first agentic campaign for Interbev and one of Europe's first fully autonomous agent-to-agent CTV campaigns executed by Abovo Maxlead in the Netherlands. Australia and India are also witnessing the onboarding of additional buyers eager to leverage AgenticOS.

AgenticOS comprises over 20 agents designed for various functions, including audience discovery, inventory curation, media activation, and deal management. The platform leverages PubMatic's extensive inventory, consisting of over 2,000 publishers and 100,000+ sites/apps, along with a robust data ecosystem of 200+ partners for enhanced targeting and analytics.

Additionally, the recent integration of PubMatic's Creative Innovation Suite into AgenticOS promises to enhance custom CTV and mobile formats, providing seamless cross-screen deployment within agentic workflows.

As PubMatic continues to innovate and expand its capabilities, the AgenticOS platform is poised to redefine the digital advertising landscape. Agencies and advertisers interested in activating AgenticOS are encouraged to contact their PubMatic account representatives or visit the company’s website for more information.

PubMatic’s commitment to building a more intelligent, profitable, and sustainable open internet underscores its role as a leader in the ad tech space, constantly adapting to meet the evolving needs of the market.
