Agencies Rethink Ownership of Agentic AI and Data
At Programmatic IO in New York, agency leaders debated the future of data and AI tool ownership. Executives from S4 Capital, Horizon Media, Dentsu, and WPP agreed that agencies should avoid owning client data and AI models to maintain neutrality and avoid conflicts of interest. They highlighted a shift from FTE-based compensation to outcome-based pricing and licensing AI tools to clients. The panel also discussed AI's impact on DSPs, with WPP's McAndrew noting a move toward agent-to-agent interactions and increased supply-chain compression. Sorrell warned of Big Tech platforms like Meta becoming end-to-end threats, pushing agencies to become validators. The discussion reflects a broader industry trend away from data ownership, contrasting with Publicis's acquisition of LiveRamp.

Agencies’ AI Operating Systems Face Commoditization Risk
Agencies have invested in proprietary AI-powered operating systems (WPP Open, Omnicom’s Omni, Stagwell’s The Machine, Havas Converged, PMG’s Alli, Horizon’s Blu, etc.) to centralize data, planning and creative tools and increase client stickiness. A Gartner research note warned that roughly half of agency-built AI platforms could fail by 2029, citing consolidation, advertisers building bespoke AI or buying from hyperscalers, and shrinking differentiation. Agency and holding-company leaders (e.g., Omnicom’s John Wren, WPP’s Stephan Pretorius) argue scale and negotiated enterprise agreements give them an advantage, while vendors such as Brandtech’s Pencil emphasize transparency about underlying models (Anthropic, OpenAI) and token-costing. The ANA survey flagged principal-media buying is widespread but governance lags. The briefing frames a growing industry debate over AI token economics, vendor transparency and whether hyperscalers will disintermediate agency platforms.
Agencies Clash Over Ownership of Agentic Workflows
Agency leaders say deploying AI agents into marketing workflows is now standard practice, but ownership, governance and best practices remain unclear. At Digiday’s Programmatic Marketing Summit town hall, anonymous agency and brand execs described inconsistent internal controls, case-by-case policing of agentic workflows, and concerns about over-reliance on generative AI for client work. Gartner research cited in the piece finds CMOs allocate an average of 15.3% of marketing budgets to AI initiatives; 70% aim to be AI leaders while only 30% feel ready to scale. Agencies are already spending on tools like Google Performance Max and Meta Advantage+. The IAB Tech Lab recently launched a Programmatic Governance Council including WPP, Disney, Magnite, Yahoo, Amazon Ads and The Trade Desk to develop governance frameworks and transparency guidance.
Agencies Discuss Adapting to AI at Marketecture Live
At Marketecture Live in New York City, a panel led by Bob Lord (President, Horizon Media), Obele Brown-West (President, Colle McVoy) and Mike Shields (Founder, Next in Media) examined how advertising agencies must adapt to rapid AI adoption. Panelists said AI brings both confusion and opportunity, but legacy technology stacks and siloed systems are the main barriers to progress. They argued the future will be platform-based, not siloed, and that AI will scale execution rather than replace human creativity. The discussion stressed upskilling existing talent over wholesale replacement, evolving agency business models, rising legal and transparency concerns, and the reconvergence of creative and media capabilities.
