Agencies Turn to AI Agents, Brands Move In‑House
Agencies are showcasing AI agent pilots, partnerships and products to speed media planning and buying — but face competition from advertisers building their own agentic capabilities. WPP is testing a media‑buying and planning agent for premium video, while Dentsu has partnered with Newton Research to trial media‑buying agents and faster analytics via Dentsu.connect. Independent agencies and consultancies such as Butler/Till and Dept are also deploying agent tooling (including Claude agents and a productised 'Agent Studio') and using Google models to accelerate delivery. Advertisers including Hyundai have built in‑house bidding agents with partners (Chalice and Canvas) using a containerized OpenXBuild solution, reporting a 67% reduction in online video CPM and a 20% decline in cost per defined 'high value action' during pilots. The piece cites WFA research on broad in‑house AI adoption and frames the trend as a strategic threat and opportunity for agencies.
Agentic AI in Advertising: Progress, But Not Transformative Yet
Karsten Weide of W Media Research provides a measured assessment of agentic AI in advertising, arguing the technology's promise outstrips current production reality. Deployments exist—largely in planning, troubleshooting, and optimization—but fully autonomous buying is rare and typically constrained by human-in-the-loop governance, fragmented data, legacy stacks, and trust issues. PubMatic, Viant, and Yahoo are highlighted as leaders/early adopters; Amazon, Google, and Meta run internal agentic capabilities with tight controls. Startups and vendors are experimenting with agent-led planning and optimization, and products like HUMAN Security’s Agentic Trust aim to increase visibility. Near-term adoption is expected to be gradual, favoring semi-autonomous workflows until governance, interoperability, and clear ROI improve.
Agentic AI Divides Ad Industry at Cannes
An Adweek column by Ryan Joe reports that 'agentic AI' — systems that chain AI agents to complete complex tasks — was a dominant topic at Cannes Lions 2026. Agencies and media companies discussed how agentic workflows could reshape operations, with major holding companies and media firms promoting 'agentic' announcements. The piece notes contrasting industry reactions, describes agencies racing to demonstrate leadership on agentic capabilities, and cites examples of firms that made agentic-related announcements during Cannes and recent upfronts.
