“Everyone’s hyping agentic advertising like it’s going to unlock massive value for publishers and make direct-sold sponsorships scalable. But is this actually going to help us—or just recreate programmatic middlemen with fancier acronyms?”
— Head of Revenue Strategy
AdCP is being sold as a bridge to the agentic future. AI-powered agents plan and transact media, using shared protocols instead of brittle DSP workflows or clunky sales calls. For execs managing high-value inventory in streaming, that pitch is definitely tempting. Less manual labor. More discoverability. A scalable way to surface all the stuff that doesn’t fit into standard auctions.
The promise is that premium inventory—custom sponsorships, event tie-ins, high-impact formats—finally becomes searchable and buyable. Not just the rectangles. The full menu. And not just to one buyer, but to any agent with access and a budget.
Sounds great. But if you’ve been around this industry long enough, you’ve heard it before.
Programmatic once promised the same thing. And what it delivered was a fragmented supply chain, unclear economics, and a system where the publishers who made the content had the least control over how it was valued and sold.
The protocols didn’t cause that. But they formalized it.
That’s the risk with AdCP and the broader agentic playbook. These standards may be open, but they’re not neutral. They encode decisions about who gets to discover what, how it’s described, and what qualifies as “valuable.” If publishers aren’t defining those rules themselves, they’ll end up responding to someone else’s idea of value. Again.
Transparency gets tossed around like a virtue here, but it cuts both ways. Agentic buying might illuminate how messy media buying actually is. That could be good for publishers, or it could be a spotlight on every manual patch, every workaround, every pricing inconsistency that used to be handled behind closed doors.
Some execs are hoping this new layer unlocks efficiency for direct deals. But others already see the warning signs. When publishers have to retool their entire stack just to be compatible, that’s not empowerment. That’s chasing relevance on someone else’s terms.
What’s getting missed in all the hype is this: AI agents only work as well as the context they’re given. If the system flattens nuance, removes judgment, or treats premium inventory like a generic input, then the results are going to look a lot like the last fifteen years of programmatic.
The only way agentic buying actually helps publishers is if they take the lead in defining how their inventory is represented, discovered, and valued. That means investing in the standards, not just adopting them. That means building logic and language into the ecosystem that reflects the actual worth of differentiated content and premium experiences.
Because if you don’t, someone else will.
Skip Says
Agentic buying won’t save you unless you’re shaping it.
Letting someone else define your value in a new protocol is just programmatic déjà vu.
Don’t mistake “discoverability” for control.
If you’re not driving how your inventory is described and bought, you’re not in the driver’s seat.
