The Digiday Podcast: "The Case Against AI Agents for Programmatic Ad Buying"
Date: December 9, 2025
Host: Tim Peterson (Executive Editor, Digiday Media)
Guest: Christopher Francia (Director of Product Development & Client Performance, Attention Arc)
Guest Co-host: Seb Joseph (Executive Editor of News, Digiday)
Overview
This episode delves into the present and future of AI agents in programmatic ad buying, specifically arguing why, despite the hype, AI (particularly large language model-driven agents) isn’t upending the space as quickly as some imagine. Live from the Digiday Programmatic Marketing Summit (DPMS), guest Christopher Francia of Attention Arc details the technological and practical limitations of current AI agents, while the Digiday team also digests major industry news (especially the landmark Netflix-Warner Bros. Discovery merger).
Key Discussion Points and Insights
1. State of AI Agents in Programmatic Buying (00:10–03:01, 34:54–55:41)
2. Major Industry News: Netflix Acquires Warner Bros. Discovery (04:38–24:27)
3. AI Licensing, Lawsuits, and Industry Shifts (25:38–33:15)
4. Structural Barriers to AI Agents in Programmatic (34:54–55:41)
-
Speed and Infrastructure Constraints
- The technical reality of programmatic: bid requests have ~15–100ms windows; even optimized LLMs can’t process (parse, score, and respond) fast enough at systemic scale.
- “When you take that, it becomes a physics problem…It’s not going to back out ever in terms of an ROI.” – Christopher Francia (41:38, 44:35)
-
Industry Stagnation and Standards
- Proposed standards and frameworks (Agentic RTB, User Context Protocol, Amazon’s RTB Fabric) aim to speed intra-platform data transfer and communication, but none solve LLM latency at real scale.
- Large tech platforms (Google, Amazon, Trade Desk) have little interest in protocols standardizing or opening budget-shifting among DSPs—they have no incentive to level the playing field for smaller rivals.
- “…That's not good for Google's business model. It's definitely not good for Trade Desk's…and it's not good for Amazon...It's really good for a mid-tier DSP who's just looking for any chance to prove itself.” – Christopher Francia (47:51)
-
Fragmentation is Baked In
- Agencies like Attention Arc build to platforms with the biggest budgets, not smaller, innovative APIs.
- “We are not spending our resources and our time building to a small API…we have to go where most of the budget is.” – Christopher Francia (49:24)
-
Where AI Works Best
- Repetitive, well-defined, lower-value tasks; rapid ideation and insights; creative workflows (not real-time dynamic creative modifications, due to brand risk).
- “We are experimenting with other stuff, but we're really more into the deterministic ML stuff when it comes to optimizations.” – Christopher Francia (54:41)
Notable Quotes & Moments (with Timestamps)
- On AI "Interns":
- “These AI agents right now are good for stuff that you would otherwise hand off to an intern.”
– Tim Peterson (02:47)
- On LLM Hallucinations & Real-World Limits:
- “It has to do very specific, narrowly tailored tasks. The more complicated a task becomes, the harder it is for AI to figure out what it’s supposed to be doing.”
– Christopher Francia (35:08)
- "[AI is] not going to be trusted on activation... brands really want to control their image and their reputation and where they're running and what their creatives say. Taking that out sounds like a great idea…but that generative real-time [creative] is very dangerous until you can have full control, which we're just not there yet."
– Christopher Francia (39:50)
- Adoption Reality Check:
- On asking a live audience if they use agentic AI for ad buys:
- “Not a single hand.”
– Tim Peterson (46:52)
- On Big Tech Resistance to Standards:
- “That's not good for Google's business model...Trade Desk...Amazon…It’s really good for a mid-tier DSP who’s just looking for any chance to prove itself.”
– Christopher Francia (47:51)
- On Brand Risk and Practical AI:
- “It just takes one mistake for that brand’s 100 year legacy to have a huge crisis.”
– Christopher Francia (39:50)
- On AI in Creative vs. Media Buying:
- “It’s been the most disruptive in creative workflows… the resources you need to do iterations of creatives have now reduced, which has made it for us to do more, take on more clients.”
– Christopher Francia (38:06)
- On Netflix’s Deal-Making Pace:
- “Netflix then announces the next morning, hey, we're acquiring Warner Brothers Discovery, everybody...This happened so quickly.”
– Tim Peterson (06:56)
- “This feels like Netflix kind of preempting that by, like, if everyone accepts this as reality, then it’s going to be inevitable that it'll close.”
– Tim Peterson (10:54)
- On the ROI of LLMs in Bidstreams:
- "The cost of doing that, to make it that fast, is not going to back out ever in terms of an ROI."
– Christopher Francia (41:38)

Tone & Style
The conversation is candid, nuanced, and skeptical—with a clear eye toward both the real technical hurdles and the ever-present marketing spin around ad tech and AI. There’s a healthy skepticism of overblown AI promises, paired with practical optimism about incremental gains in agency workflow, ideation, and performance reporting.
Summary
This episode makes a compelling case that, despite the hype, large language model-based AI agents are nowhere close to autonomously running programmatic ad buying. Real impact lies in automating rote work, enriching campaign insights, and accelerating creative iteration—not in replacing high-value strategic or commercial jobs. The biggest barriers are not just technological (speed, reliability, interpretability) but also business incentives and industry inertia. Meanwhile, seismic shifts continue at the platform and publisher level, promising even bigger changes ahead for media and advertising in 2026.
