The two companies will create a combined giant with $23 billion in revenue, beating out the current market leader, WPP. But a merger between the France-based Publicis and US-based Omnicom, each of which is a holding company for large networks of ad firms, is likely to face antitrust obstacles and would create possible conflicts for rival clients of the combined firm, such as Pepsico and Coca-Cola.
