PubMatic’s AgenticOS Platform Propels Autonomous Campaigns and Redefines Publisher Monetization
New York, NY – May 8, 2026 – PubMatic, a leading sell-side platform (SSP), is aggressively advancing the adoption of agentic advertising technology, signaling a fundamental shift away from traditional direct ad buys. The company announced today that it has successfully executed over 30 fully autonomous, end-to-end agentic campaigns through its proprietary AgenticOS platform. This milestone, revealed by CEO Rajeev Goel during PubMatic’s first-quarter earnings call on Thursday, underscores the platform’s growing influence and PubMatic’s strategic pivot towards AI-driven advertising solutions.
The proliferation of these advanced agentic campaigns is not merely an operational achievement; it’s a significant revenue driver. PubMatic reported an 80% year-over-year growth in its emerging revenue category, directly attributed to the scaling of AI-powered deals. This burgeoning segment now constitutes 14% of the company’s total revenue, contributing substantially to its overall 13% year-over-year growth in the first quarter. PubMatic’s total revenue for Q1 reached $62.6 million, buoyed by double-digit year-over-year increases in monetized impressions. Standalone growth in Connected TV (CTV) advertising was reported at 18% year-over-year, while mobile app revenue saw a robust 25% expansion.
The "agentic advantage," as articulated by Goel, centers on enhanced efficiency and cost-effectiveness for advertisers. Early adopters of AgenticOS are reporting a 30%-40% improvement in Cost Per Mille (CPM) rates. This efficiency stems from the platform’s streamlined approach, which bypasses multiple ad tech intermediaries, thereby reducing associated fees. Buyers are also gaining access to an additional 40% of publisher inventory, as the end-to-end agentic deals processed through PubMatic’s platform eliminate the need for secondary ad tech layers.
"It’s a single layer of technology, and it looks a lot like what the walled gardens leverage to drive ad performance," Goel remarked to investors, drawing a parallel to the sophisticated internal systems used by major tech giants. This consolidation of the ad tech supply chain is further amplified by PubMatic’s Activate direct-to-buyer connection, which has tripled its business since the first quarter of the previous year. Concurrently, its Connect data platform has expanded its network to include over 300 data and commerce media partners, featuring prominent names such as Walmart Connect and PayPal Ads.
Mobile and CTV Drive Substantial Revenue Growth
PubMatic’s mobile app business has emerged as a significant revenue engine, experiencing a 25% year-over-year surge. This growth, coupled with a 5% increase in display advertising, highlights the platform’s comprehensive reach. Combined revenue from mobile and omnichannel video now accounts for a substantial 79% of PubMatic’s Q1 revenue. The company has solidified its position within the mobile ecosystem by integrating with the three leading mediation platforms: AppLovin Max, Google AdMob, and Unity LevelPlay. This strategic integration grants PubMatic access to more than 90% of global mobile SDK inventory, a crucial gateway for advertisers targeting mobile consumers.
Further bolstering its AI capabilities, Goel highlighted the AgenticOS Creative Innovation Suite. This AI-powered tool is designed to generate consistent creative assets tailored for viewers across CTV, mobile, and online display touchpoints. Agencies such as Horizon Media, Crossmedia, and Kelly Scott Madison have reportedly adopted this suite, signaling its growing utility in delivering cohesive cross-platform advertising experiences.
Goel expressed confidence that these advancements provide a solid foundation for sustained AI-driven growth. PubMatic reaffirmed its prior projection for double-digit growth in the second half of the current year. However, some investors have voiced skepticism regarding the long-term revenue sustainability of PubMatic’s agentic AI business. Concerns were raised that the volume of direct deals and autonomous campaigns, while growing, still represents an "immaterial percentage" of PubMatic’s overall business.
In response, PubMatic CFO Steve Pantelick elaborated on the broader impact of AI across the company’s operations. He explained that AI is also enhancing publishers’ campaign setup and troubleshooting processes, leading to greater efficiency. Pantelick anticipates that these incremental improvements, alongside continued momentum in mobile and CTV, will drive sustained double-digit growth.
Navigating DSP Competition and Market Dynamics
Despite the optimism surrounding AI, PubMatic continues to grapple with persistent industry challenges, particularly the competitive landscape between Demand-Side Platforms (DSPs) and Supply-Side Platforms (SSPs) vying for direct advertiser business. The company acknowledged ongoing headwinds from a major, unnamed DSP—widely understood to be The Trade Desk—which has reduced its spending on PubMatic’s SSP. This reduction is largely attributed to the increased adoption of The Trade Desk’s OpenPath solution, a direct-to-publisher offering that bypasses SSPs.
This competitive pressure contributed to a 12% year-over-year decline in PubMatic’s U.S. revenue during the first quarter. However, this domestic contraction was effectively offset by significant growth in other regions, with the Asia-Pacific market expanding by 25% and the Europe, Middle East, and Africa (EMEA) region showing a 10% increase.
The impact of the unnamed DSP’s reduced activity is projected to continue influencing PubMatic’s earnings in the second quarter, with the company forecasting a revenue decrease of between 2% and 4%. Several investors sought clarification on the extent of this impact. Pantelick reassured stakeholders that the revenue generated from this specific DSP in Q1 exceeded initial expectations, a result of PubMatic’s efforts to "optimize our platform to meet the needs of this buyer." The company anticipates fully lapping the effects of this DSP’s strategic shift by the third quarter.
To mitigate the financial impact of this DSP’s reduced engagement, PubMatic has actively diversified its partnerships. The company onboarded more than 50 additional DSPs last year and reported a 20% increase in integrations with mid-market DSPs in the first quarter. Furthermore, PubMatic secured a significant partnership with Amazon DSP this quarter, integrating Amazon’s Dynamic Traffic Engine. This integration has reportedly boosted publisher CPMs by up to 10% since its implementation.
Strategic Outlook and Future Growth Avenues
Looking ahead, PubMatic is undertaking strategic organizational changes. The company is actively seeking replacements for Kyle Dozeman, CRO of the Americas, and Paulina Klimenko, Chief Growth Officer, both of whom are departing. Goel indicated that PubMatic is exploring ways to consolidate some of their responsibilities into a newly created global Chief Revenue Officer (CRO) position, aiming for greater global synergy.
PubMatic identifies continued growth opportunities in serving mid-market, performance-focused DSPs and mid-size independent agencies. These entities have demonstrated a more agile adoption of AI solutions compared to their larger, established counterparts.
The company also expressed keen interest in collaborating with OpenAI, particularly as ChatGPT expands its advertising capabilities. PubMatic has already been engaging with smaller AI players, such as Kontext and Dappier, and is actively "innovating on the ad formats and appropriate signals to monetize that kind of inventory." Goel cited OpenAI’s ambitious goal of generating $100 billion in ad revenue by 2030 as a clear indicator of their reliance on established platforms like PubMatic. "It’s going to be an ecosystem-wide effort for them to get to that level," he stated, emphasizing the collaborative nature of future advertising endeavors.
The company’s strategic focus on agentic technology, coupled with its expanding global reach and diversification of partnerships, positions PubMatic to navigate the evolving digital advertising landscape. While challenges from competitive pressures persist, PubMatic’s proactive approach to AI integration and platform optimization suggests a resilient strategy for future growth. The sustained investment in its AgenticOS platform and its ability to adapt to market dynamics will be critical in solidifying its position as a key player in the next generation of programmatic advertising.
