The advertising technology landscape is undergoing a seismic shift, with PubMatic, a leading sell-side platform (SSP), reporting significant advancements in its agentic ad tech capabilities. The company announced during its first-quarter earnings call on Thursday that the era of agentic advertising solutions being exclusively confined to direct ad buys is rapidly drawing to a close. PubMatic CEO Rajeev Goel revealed that the company has successfully executed over 30 fully autonomous, end-to-end agentic campaigns utilizing its proprietary AgenticOS platform. This milestone builds upon more than 1,000 direct publisher deals that have already been processed through AgenticOS as of the first quarter of 2026.
The strategic integration and scaling of these AI-driven deals have been a primary catalyst for an impressive 80% year-over-year growth rate within PubMatic’s emerging revenue category. This burgeoning segment now accounts for a substantial 14% of the company’s total revenue, underscoring the growing market appetite for sophisticated, automated advertising solutions. This AI-driven expansion contributed significantly to PubMatic’s overall 13% year-over-year revenue growth in Q1, with total revenue reaching $62.6 million. Furthermore, the company experienced double-digit year-over-year growth in monetized impressions, a key performance indicator for ad inventory utilization. Within this growth, Connected TV (CTV) emerged as a standalone category, showing an 18% year-over-year increase, while mobile app revenue demonstrated robust expansion, growing by 25%.
The Agentic Advantage: Efficiency and Cost Savings
PubMatic’s AgenticOS platform is not merely a financial boon for the company; it is demonstrably enhancing campaign efficiency for its clients. According to CEO Rajeev Goel, buyers leveraging the solution are reporting a significant improvement in Cost Per Mille (CPM) rates, with gains ranging from 30% to 40%. This enhanced efficiency is attributed to the platform’s streamlined approach, which eliminates multiple ad tech intermediaries and their associated fees. Consequently, buyers are able to acquire approximately 40% more publisher inventory compared to traditional methods.
"It’s a single layer of technology, and it looks a lot like what the walled gardens leverage to drive ad performance," Goel stated, drawing a parallel to the sophisticated systems employed by major technology platforms. This consolidation of the ad tech supply chain is further bolstered by PubMatic’s Activate direct-to-buyer connection, which has experienced a threefold increase in business since the first quarter of the previous year. Complementing this is the Connect data platform, which now boasts an expansive network of over 300 data and commerce media partners, including prominent players like Walmart Connect and PayPal Ads.
The mobile app business, a significant revenue driver for PubMatic, recorded a 25% year-over-year growth, contributing to the SSP’s 5% expansion in display advertising revenue. Collectively, mobile and omnichannel video generated 79% of PubMatic’s Q1 revenue. The company’s strategic integrations with the mobile market’s three leading mediation platforms – AppLovin Max, Google AdMob, and Unity LevelPlay – provide PubMatic with access to over 90% of global mobile SDK inventory.
Adding another layer of innovation, Goel highlighted the AgenticOS Creative Innovation Suite. This AI-powered tool is designed to generate consistent creative assets across various advertising touchpoints, including CTV, mobile, and online display. Agencies such as Horizon Media, Crossmedia, and Kelly Scott Madison have already adopted this creative suite, signaling a growing industry recognition of its capabilities. These advancements collectively provide PubMatic with a solid foundation for sustained AI-driven growth. The company has reaffirmed its previous Q4 projection of achieving a double-digit growth rate in the second half of 2026.
Despite these positive indicators, some investors have expressed skepticism regarding the long-term revenue growth sustainability of PubMatic’s agentic AI business. One investor pointed out that while AgenticOS is powering over 1,000 direct deals and more than 30 end-to-end autonomous campaigns, this still represents an "immaterial percentage" of PubMatic’s overall business. In response, PubMatic CFO Steve Pantelick emphasized that AI’s impact extends beyond direct campaign execution. He noted that AI is also streamlining internal processes, such as accelerating campaign setup and troubleshooting for publishers, and expressed confidence that these efficiencies will continue to drive double-digit growth alongside the strong performance of mobile and CTV.
Navigating DSP Competition and Market Dynamics
While PubMatic is aggressively pursuing AI-driven opportunities, the company is also contending with the persistent challenge of competition between Demand-Side Platforms (DSPs) and Supply-Side Platforms (SSPs) for direct advertiser business. A significant headwind has been the reduced spending from a major, unnamed DSP – widely understood to be The Trade Desk – on PubMatic’s SSP. This pullback is likely a consequence of 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 US revenue during Q1. However, this regional dip was effectively offset by robust growth in other markets, with the Asia-Pacific region experiencing a 25% increase and Europe, the Middle East, and Africa (EMEA) seeing a 10% expansion.
The impact of this unnamed DSP’s reduced engagement is projected to continue as a drag on Q2 earnings, with PubMatic forecasting a revenue decrease of between 2% and 4% for the upcoming quarter. In response to investor inquiries seeking clarity on the DSP’s impact, Pantelick stated that revenue from the DSP in question actually exceeded expectations in Q1, a testament to PubMatic’s efforts to "optimize our platform to meet the needs of this buyer." The company anticipates fully lapping the impact of this DSP’s pullback by the third quarter.
To mitigate the losses stemming from this specific DSP, PubMatic has proactively expanded its partner ecosystem. The company added over 50 new DSPs to its partner list last year and achieved a 20% growth in integrations with mid-market DSPs in Q1. Furthermore, PubMatic secured a strategic integration with Amazon DSP this quarter, incorporating Amazon’s Dynamic Traffic Engine. Since its implementation, this integration has reportedly improved publisher CPMs by up to 10%, according to Goel.
Strategic Outlook and Future Growth Avenues
Looking ahead, PubMatic faces immediate organizational changes with the departure of Kyle Dozeman, CRO of the Americas, and Paulina Klimenko, Chief Growth Officer. Goel indicated that the company is exploring the consolidation of some of their responsibilities into a new global Chief Revenue Officer (CRO) position, signaling a strategic realignment to streamline leadership.
PubMatic views significant growth opportunities in serving mid-market, performance-focused DSPs and midsize independent agencies. These entities have demonstrated a quicker adoption rate of AI solutions compared to their larger, more established counterparts within major holding companies.
In a move that aligns with the burgeoning generative AI sector, PubMatic is also keen to collaborate with OpenAI as ChatGPT opens its doors to advertising. Goel revealed that the SSP has been actively working with smaller AI players such as Kontext and Dappier and is "already innovating on the ad formats and appropriate signals to monetize that kind of inventory." He pointed to OpenAI’s ambitious target of generating $100 billion in ad revenue by 2030 as a clear indicator that collaboration with platforms like PubMatic will be essential for achieving such scale. "It’s going to be an ecosystem-wide effort for them to get to that level," Goel concluded, highlighting the collaborative nature of success in this evolving market. The company’s forward-looking strategy emphasizes leveraging AI, expanding its partner network, and adapting to the dynamic competitive landscape to ensure sustained growth and market leadership.
