February 27, 2026 — FRANCE — COMvergence’s ten-year analysis of marcom agency acquisitions reveals a decisive structural shift in the global marketing services industry.
In 2025, 55 marcom acquisitions were completed worldwide, marking a modest increase versus 2024 but remaining well below the 2016 peak. While deal volume remains structurally lower across the decade, 2025 stands out for a transformational event:
Omnicom’s acquisition of Interpublic Group (IPG), the largest transaction recorded in the study’s history. The transaction adds 53,300 employees and $10.7B in revenue, reshaping global competitive scale and effectively ending the long-standing “Big 6” holding company structure.
