Agentic Ad Buying Gains Ground in IAB Europe AI Report
IAB Europe has released its 2026 AI report, highlighting the growing adoption of agentic ad buying within the European advertising industry. The report details a significant shift towards autonomous AI agents that can plan, negotiate, and execute media transactions with minimal human intervention. This trend is expected to enhance efficiency and personalization in digital advertising, though it also raises new challenges around transparency, governance, and the role of traditional trading desks. The report underscores the need for industry standards to ensure responsible deployment of agentic technologies.
AI in Media Buying: Expectations Outpace Experience
A new IAB Europe study reveals that while 58% of industry professionals expect agentic ad buying to become mainstream within a year, actual adoption lags significantly. Of 47 respondents, 36 have either not yet deployed agentic systems or use technologies where humans still control planning and execution. The 'Impact of AI on Digital Advertising Report 2026', based on 50 interviews, shows that AI is widely used for reporting and campaign analysis (86% overall), but only 11 out of 29 detailed respondents use it for agentic buying and selling. A complementary survey by StackAdapt (500 marketers, 6 countries) found similar patterns, with half citing fragmented data pipelines as a barrier. Companies are cautious about granting full autonomy, with most preferring human-in-the-loop models. The average performance rating for AI in operational advertising was only 2.76 out of 5. The industry is still defining governance, training, and integration practices to bridge the gap between expectations and real-world experience.
IAB Europe Survey: Efficiency Remains Key AI Metric
A new IAB Europe survey, the 2026 Impact of AI on Digital Advertising Report, reveals that despite high AI adoption, operational efficiency remains the primary metric for judging AI performance. The survey of 50 industry respondents found 92% use AI internally and 86% in marketing. Reporting is the most common AI workflow (76%), followed by programmatic optimization (59%). Agentic AI is still nascent, with most companies at low autonomy levels. However, AI performance ratings are mediocre (2.76/5), and efficiency (69%) and CPM improvement (48%) are the top evaluation criteria. There is tension between current delivery and future expectations, with 30% expecting agentic ad buying to become mainstream within a year.
