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.

Publicis ownership of LiveRamp splits marketer opinion
Publicis Groupe has closed its $2.2 billion acquisition of LiveRamp, prompting marketers to decide whether to continue using the identity resolution platform. Proponents highlight LiveRamp's market-leading position, its RampID alternative ID, and its OpenAI partnership, alongside FTC-imposed safeguards to ensure competitor access and data firewalls. Critics, including rival holding companies WPP and Omnicom, worry about neutrality and competitive advantage, with some clients seeking alternatives like InfoSum or Omnicom's Real ID. The deal is set against a backdrop of shifting identity strategies, increasing reliance on probabilistic and contextual targeting, and Apple's crackdown on identity resolution. The outcome will shape the future of data-driven advertising as agencies and brands reassess their identity infrastructure.
- Publicis Groupe closed its $2.2 billion acquisition of LiveRamp on Nov. 2, 2026.
