Updated on Nov. 2, 2026 in Advertising
Publicis Groupe announced on November 2, 2026, that it has closed its acquisition of LiveRamp. The company is combining LiveRamp's collaboration platform with Epsilon's identity technology into a single AI growth engine.
Why it matters
The stated rationale is that clients need to deliver growth today while rebuilding their systems for AI agents. The combination is positioned as a way to modernise data and technology infrastructure for advertisers operating across more than 100 countries.
Clients can natively enrich first-party data with RampID and Epsilon's Identity and activate it through clean rooms and zero-copy capabilities. The announcement does not disclose deal terms or financial impact on Publicis Groupe.
The players

Epsilon
A data and marketing technology company known for its identity resolution capabilities, now combined with LiveRamp's platform under Publicis.

Timeline
November 2, 2026: Publicis Groupe announces the closing of its acquisition of LiveRamp.
The Tech Race
The deal extends LiveRamp's RampID identity and clean-room collaboration model by bringing it under a holding company that is building an AI growth engine. It positions Publicis against rival agency groups competing to offer data-driven, agent-ready marketing infrastructure.
Advertisers working with LiveRamp or Epsilon may see the two platforms' data and identity tools offered through a single Publicis-run system. The announcement does not specify changes to pricing or contract terms for existing clients.
The takeaway
Marketers should watch whether the combined LiveRamp and Epsilon tools reduce the cost of connecting first-party data across clean rooms. The practical test is how cleanly the new offering works inside existing client environments.
