Omnicom's Trade Desk Audit: A Battle for Programmatic Margins, Not Just Transparency

• Omnicom's audit of The Trade Desk, following Publicis, signals a deeper structural reset in programmatic advertising, not just a compliance check.
• Industry executives suggest the scrutiny is a battle over economics and margin realignment, as agencies face pressure from advertisers for outcome-driven models.
• Long-standing practices like principal-based buying and inventory markups are under scrutiny as the programmatic supply chain's intermediation is exposed.
• DSPs' direct engagement with clients creates friction, shifting the agency-platform relationship from collaborative to competitive.
• AI and automation are accelerating this shift, making inefficiencies detectable and pushing for greater transparency, fundamentally impacting revenue models.
