PubMatic and Havas Launch the First Agentic CTV Campaign in Spain for Telefónica, Achieving 18% Lower CPM Vs Target

The campaign marks the first HoldCo adoption of agentic advertising in Spain, combining autonomous AI with direct access to premium CTV inventory for measurable efficiency gains

PubMatic (NASDAQ:PUBM), the leading AI-powered ad tech company delivering digital advertising performance, announces its first agentic advertising campaign in Spain, developed in partnership with Havas for client Movistar, part of Telefónica Group, a leading provider of telecommunication services. The campaign marks a key milestone in the adoption of agentic AI within programmatic media buying across Europe, bringing new levels of automation, transparency, and efficiency to Connected TV (CTV).

The campaign was executed using AgenticOS, PubMatic's proprietary AI operating system that uses autonomous agents to plan, manage, and optimise campaigns in real-time through Activate, PubMatic's direct-to-supply media buying platform.

By processing a natural language brief through the Claude Large Language Model (LLM), AgenticOS converted campaign objectives into a live programmatic activation. Agents working across the platform ingested the campaign brief, autonomously selected CTV inventory, applied frequency controls and brand safety parameters, and optimised bids in real-time, all while following the client's specific guardrails and preferences. This process freed the Havas team to focus on strategy and client outcomes, while the platform delivered efficiency, precision, and full transparency across the entire campaign.

A new benchmark in AI-driven efficiency for CTV advertising

Spain's CTV market is growing rapidly and European businesses are increasingly ready to meet it: 68% of EU businesses believe adopting agentic technology will give them a competitive advantage, according to the American Express Business Barometer. This campaign demonstrates what's possible when that readiness meets agentic automation and direct inventory access at scale. AgenticOS reduced setup time by up to 80%, enabling deployment within minutes while maintaining consistent standards of accuracy and transparency.

Campaign results validated the approach decisively: CPM came in 18% below target and impressions exceeded target by 23%. The campaign ran in-stream across high-quality, brand-safe CTV environments, with frequency controls per user and direct access to Spain's premium CTV publishers. Cost efficiency and reach performance improved simultaneously, not as a trade-off.

As Germán Becker, Digital Transformation Manager at Havas Media Network, explains, "this campaign with Movistar is a clear example of how agentic AI can transform the way we plan and activate media in CTV. At Havas, we believe in solutions that bring greater control, transparency, and measurable results for our clients, and this collaboration with PubMatic clearly moves us in that direction. AgenticOS helps us streamline execution across platforms and data sources, enabling our team to dedicate more time to strategy and client partnerships."

Pablo Morales, Director, Advertiser Solutions, PubMatic, adds "This campaign proves that agentic technology is no longer a pilot concept. A global Holding Company and a Tier 1 telco have now run a fully agentic programmatic campaign in Spain, with results that outperformed on every metric. The question for the rest of the market is not whether agentic works. It is how quickly they choose to move."

Esther López, Head of Media, Telefónica, also commented, "By working with Havas and PubMatic, we have demonstrated that agentic AI can operate with the level of rigour and performance that brands require. This is not an experiment. It is the foundation of a smarter and more responsible way to invest in media. What it unlocks for the future—greater precision, less friction, and more room for the thinking that truly drives business results—is what excites us the most."

AgenticOS, launched at CES in January 2026 and already deployed across multiple markets, is an operating system of more than 20 agents that includes: Audience Discovery, Inventory Marketplace and Curation, Media Activation, including brand safety and budget capping, Deal Management, Fee Transparency, and Insights, and connects to partner agents, inventory and data partners through current and new protocols. These agents operate across PubMatic's compounding assets: premium inventory spanning 2,000+ publishers and 100,000+ sites and apps, including 28 of the top 30 global streamers; a data ecosystem of 300+ data and commerce media partners giving agents continuously learning targeting and audience capabilities; and direct activation through Activate, enabling real-time buying without intermediaries — all running on advanced owned and operated infrastructure purpose-built for accelerated computing and analytics.

This Spanish activation follows the success of PubMatic's recent AgenticOS campaigns with Abovo Maxlead in the Netherlands and Amnet in France for its client InterBev underscoring the company's accelerating EMEA expansion and growing momentum in bringing AI-powered, agentic advertising solutions to market across the region.
