Rewiring Omnicom’s Operating Model for AI at Scale

Omnicom is reworking its operating model to become a more integrated enterprise, not just a loose holding company.

The company is centralizing non-core functions, expanding outsourcing, and using shared platforms to support AI across workflows.

Its late-2025 Interpublic Group acquisition is accelerating integration of data, systems, and capabilities.

The goal is to improve efficiency, unify first-party data, and deliver more precise, measurable marketing for global clients.
