Publicis CEO Arthur Sadoun just made something clear: despite a very public dispute with The Trade Desk over undisclosed fees, he has “absolutely no intention” of building a competing platform.
That’s a striking stance.
At a moment when one of the world’s largest agency holding companies is openly challenging the economics of programmatic advertising, it’s choosing not to disrupt the system itself. Instead, it’s signaling something more revealing: even the biggest players may not be equipped to rebuild what comes next.
Because this moment isn’t just about The Trade Desk. It’s about the model.
The advertising industry has spent the past few weeks dissecting The Trade Desk’s failed audits at Publicis and Omnicom. While many expected the next major reckoning in programmatic advertising to center on fraud, these audits point to something else entirely: fees.
That shift matters.
For years, fraud has dominated the conversation. As someone who helped build the online video advertising market, I watched it grow from virtually zero to an estimated $100 billion annual problem. But despite the scale, fraud has proven stubborn—persistent, adaptable, and difficult to fully eliminate.
Fees, on the other hand, are far more vulnerable.
Publicis and Omnicom allege that The Trade Desk charged fees that were never explicitly agreed to. Whether or not those claims hold, the larger issue is now unavoidable: the programmatic ecosystem has become layered with opaque costs, margin stacking, and incentives that don’t always align with advertisers.
And yet, even amid this tension, Publicis isn’t trying to build an alternative.
That’s because the real disruption isn’t going to come from another DSP.
Agentic AI doesn’t just optimize campaigns: it replaces the need for manual execution altogether. What programmatic advertising did to media buying, introducing automation, Agentic AI will complete by removing the human layer still required to operate it. No more “hands on keyboards.” No more incremental adjustments designed to protect margins. No more preferential treatment for certain publishers or private marketplaces.
In short, no more room to hide fees.
Today’s demand-side platforms operate at extraordinarily high margins, often in the 75–85% range. Those economics exist because the system still depends on human intervention, fragmented tools, and limited transparency. Agentic AI collapses that structure. It executes, optimizes, and reallocates spend continuously, without regard for legacy incentives.
We’re already seeing early signs of this shift.
With the introduction of our generative AI tools, we reduced cost per order further to $60 by identifying and targeting high-intent consumers more effectively. That 33% improvement wasn’t the result of better negotiation or incremental tuning—it came from fundamentally better decision-making at scale.
Now, with fully agentic systems, that trajectory continues. Automation is no longer a feature; it’s the operating model.
This is the part of the story that makes the industry uncomfortable. Fees, long embedded, often justified, and rarely scrutinized, are not going to survive in their current form. Not because of regulation or audits, but because they become unnecessary.
And unnecessary costs don’t persist.
The standoff between Publicis and The Trade Desk may look like a power struggle between incumbents. In reality, it’s something else: a signal that the current system is being questioned, but not yet replaced.
Agentic AI is that replacement.
It won’t just improve advertising.
It will eliminate the economic foundations the current ecosystem depends on.
