Publicis Groupe CEO Arthur Sadoun is enjoying his company’s position as the world’s largest advertising holding company—for now. 

If Omnicom’s acquisition of IPG passes regulatory scrutiny, Publicis will return to its challenger No. 2 position amid the “big six,” with the new Omnicom as its larger competitor.

But for Sadoun, Omicom’s proposed takeover of IPG creates more opportunity for Publicis than not, he shared with ADWEEK ahead of the company’s Q4 and full year 2024 earnings call on Feb. 4.

“This acquisition by Omnicom [of] IPG is really, for the industry, back to the future,” he said, adding that the new Omnicom will match WPP in size when it was Publicis’ largest opponent, with a roughly $20 billion market cap.
