Episode Title: AI Is Quietly Breaking Retail Media — And No One Wants to Admit It
Host: Kiri Masters
Air Date: May 12, 2026
Duration: ~10 minutes

Episode Overview

In this thought-provoking episode, host Kiri Masters delivers a concise, urgent analysis of how AI-driven commerce is undermining the foundational assumptions of retail media. Drawing on a recent conversation with James Deaker (from his "Yield Doctor" podcast), Masters argues that AI answer engines and shifting consumer behaviors threaten the value and relevance of retail media ad placements—yet few inside the industry are addressing this looming disruption, largely due to leadership's short-term incentives.

Key Discussion Points and Insights

1. The Endemic Advertiser Dynamic

[00:49] James Deaker: When compared to traditional digital media (like at Yahoo), retail media is built on tight, ‘endemic’ relationships between retailers and brands. Endemic brands have no immediate replacement if they pull back.
- Quote:
  
  “When I was at Yahoo… we didn’t worry if an advertiser wasn’t seeing the performance because there were a hundred or a thousand others who would be next in line for that same impression. Often you see in retail media… you have to pay [endemic partners] special attention.”
  — James Deaker [00:49]
[01:26] Kiri Masters: Highlights that this model assumes shoppers arrive at the retailer's site with open intent, ready to be persuaded.

2. The Hidden Risk: AI Answer Engines and Upstream Decision-Making

[01:26-02:34] Masters notes that AI answer engines (like ChatGPT or Gemini) are now handling product discovery and decision-making upstream from retailers, meaning shoppers arrive at retailer sites with their minds already made up.
- Quote:
  
  “If the discovery, comparison and decision making all happen upstream in an AI answer engine before the shopper hits the retailer’s surfaces, then those endemic partners are paying for ad inventory that’s increasingly disconnected from where their customer actually got persuaded.”
  — Kiri Masters [01:32]
Ad inventory becomes less valuable as shoppers arrive “later in their journey”—fewer behavioral signals for retailers, less opportunity for persuasion.

3. Contrarian Take: Leadership Tenure and Avoidance

[02:45] Deaker challenges Masters for a big contrarian belief:
- Quote:
  
  “If you had to pick one belief about retail media networks that executives currently have, but which you believe is wrong, what would that be and why?”
  — James Deaker [02:34]
[02:45-05:37] Masters: Leaders ignore long-term existential threats because their job horizon is short (1-2 years).
- AI-enabled commerce threatens the core of retail media, but leaders "aren’t in that job… when the bill comes due.”
- Retailers have little incentive to warn advertisers and risk budget flowing to AI engines, so they stay quiet.
- Quote:
  
  “I think that AI enabled commerce is a serious threat to retail media that is not being taken seriously because the timeline doesn’t really line up with the tenure of people running these media networks.”
  — Kiri Masters [02:45]
- Quote:
  
  “If I’m head of a retail media network... I’m thinking about my numbers this year, next year, and that might be it.”
  — Kiri Masters [03:07]

4. What Happens Next: Reconfiguring Retail Media

[03:57-04:52] Masters predicts retail media will survive, but where the ad dollars and inventory "live" will be disrupted:
- Sponsored products and endemic partnerships don’t “die,” but the valuable surfaces shift.
- Retailers need to invest in “durable surfaces” like in-store experiences, post-purchase touchpoints, and loyalty programs—places AI can’t easily displace.
Quote:

“Sponsored product ads don’t die… the places where they live get reconfigured. Where retailers need to invest… in ad inventory needs to change. They need to think about where are the durable surfaces, where can they be competitive… It is an opportunity for a reset.”
— Kiri Masters [04:24]

5. Industry-Wide Apathy and Willful Blindness

[06:05] Many leaders, sharing the view expressed by experts like Sam Curry at Marketecture and on podcasts like "adsn," avoid discussing these long-term risks; they hope the problem “just goes away.”
- Quote:
  
  “There really isn’t any incentive for retail media network leaders to concern themselves with this problem in the short term… People are generally trying to hide a little bit from it and hoping that it just goes away.”
  — Kiri Masters (paraphrasing Sam Curry) [06:57]

Notable Quotes & Memorable Moments

Retailer Incentives:

“Chances are they're not in that job or even at that company when the bill comes due.”
— Kiri Masters [00:09]
AI Commerce’s Impact:

“I might still be buying that product on the retailer website… But all of that data stream that retailer had access to before is starting to disappear.”
— Kiri Masters [03:30]
Industry Response:

“If you’re running a retail media network in 2026, the rational move is to keep growing the existing surfaces…and maybe let your successor deal with the structural problem.”
— Kiri Masters [06:27]

Conclusion & Takeaways

Kiri Masters rings the alarm: AI is steadily eroding the core leverage of retail media by shifting discovery and persuasion upstream, but leadership's short-term focus ensures few are addressing it. Instead of forecasting the “death” of retail media, Masters calls for a pragmatic reorientation—urging the industry to invest in “durable” touchpoints that AI cannot easily disrupt. The episode ends with a clear warning that the time to adapt is now, before AI answer engines finish reconfiguring the retail media landscape.

A
I don't think that anyone who is running a retail media network has any incentive at all to sound the alarm on what AI enabled commerce is actually doing to their business model. Chances are they're not in that job or even at that company when the bill comes due. That was the contrarian take that I landed on at the end of a recent conversation with James Deaker on on his podcast Yield. Dr. James asked me at the very end to name one belief that retail media executives currently hold that I think is wrong. And I had been chewing on that answer for the whole conversation. But before I get to that, James actually set this structural vulnerability up earlier in the interview even better than I could have. So let's start right there.
[00:50]
B
Here's James When I first started working with retail media companies, it struck me that they have to pay more attention to their partners and advertisers. When I was at Yahoo, I'm ashamed to say to some extent we didn't worry if an advertiser wasn't seeing the performance because there were a hundred or a thousand others who would be next in line for that same impression. Often you see in retail media that particularly the endemic partners, the ones who are already working with the retailer as the owner of the retail media network, you have to pay them special attention.
[01:27]
A
James is right. At Yahoo, advertisers were interchangeable. But at Home Depot, for example, where I was at their upfronts, the advertiser base is largely endemic. If a paint brand pulls back, there isn't always another paint brand waiting in line to fill that exact slot. Now, that dynamic is the foundation that retail media is built on. The endemic relationship is often the whole game, or at least the majority of it. But that foundation has a hidden assumption baked into it. Shoppers actually arrive at the retailer with intent that hasn't already been formed elsewhere. Because if the discovery, comparison and decision making all happen upstream in an AI answer engine before the shopper hits the retailer's surfaces, the then those endemic partners are paying for ad inventory that's increasingly disconnected from where their customer actually got persuaded. Which brings me to the contrarian answer.
[02:35]
B
If you had to pick one belief about retail media networks that executives currently have, but which you believe is wrong, what would that be and why?
[02:46]
C
Okay, I think that AI enabled commerce is a serious threat to retail media that is not being taken seriously because the timeline doesn't really line up with the tenure of people running these media networks.
[03:06]
B
Say more.
[03:08]
C
Okay, so if I'm head of a retail media network, I'm thinking about My numbers this year, next year, and that might be it. And this agentic, not even agentic commerce where bots are buying things for us, but AI facilitated commerce, AI enabled commerce. I'm doing my discovery in AI answer engines now. I'm not going to a retailer to figure out what type of hair styling tool I'm going to buy. I'm doing that in ChatGPT. So that means I'm dropping less behavioral signals at a retailer. I'm not tell, I'm not browsing, I'm not searching, I'm not leaving these, you know, clues behind me about my future purchase intent. I might still be buying that product on the retailer website. Great. But all of that data, that data stream that that retailer had access to before is starting to disappear. And then also like the surfaces that these ads live on are getting less traffic and less time because I'm getting to the retailer later in my shopping journey. So I don't think that the retailers have any incentive to sound the alarm on this because they're going to spook their advertisers and advertisers might start pulling out and God, spend the money on ChatGPT instead. Like that. Don't want that. Not recommending that by the way. But this, so this is something I think is, it is a serious problem. It is not short term enough for anyone to really start talking about. But I'm, I'm, I'm, I'm sounding, I'm sounding the alarm and I think that what it means ultimately is retail media doesn't die. Sponsored product ads don't die, but the places where they live get reconfigured. The where where retailers need to invest in their in ad inventory needs to change. They need to think about where are the durable surfaces, where can they be competitive? How can they have a, like a, an honest partnership with brands to grow the category rather than this extraction tax kind of perception that there is now. So I think it is an opportunity for a reset of retail media. It's not necessarily the, the end of it, but we need to start talking about it now so we can plan for that future.

Miracle Ads is the only retail media solution designed for both 1P and 3Pmarketplace brands. Why does that matter? Marketplace sellers demand a seamless advertiser experience that still offers full funnel ad formats. And retailers need a flexible solution that allows you to scale your media business. Learn more@miracle.com that's M I R A K L.com the piece of this that I want to develop further is the tenure Misalignment because I don't think I gave it enough air in this conversation. The average tenure of a retail media network leader is fairly short. To be fair, this is a relatively recent sort of position to have, but people tend to move around quite a bit. And the disruption that we're talking about here, which is meaningful shifts in where consumers do their discovery and how much behavioral data retailers continue to capture that plays out over a longer horizon than most of these leaders. KPIs where they're focused on making their numbers this year or maybe next year. So if you're running a retail media Network in 2026, the rational move is to keep growing the existing surfaces, the on site sponsored product ads, maybe exploring some new channels with off site and in store. You want to hit your numbers and maybe let your successor deal with the structural problem. Sounding the alarm now means potentially spooking your endemic advertisers that James was talking about. Because as the AI AD economy develops and ChatGPT is sort of on a tear right now announcing all of these advertising features, I.e. there is a risk that there's going to be some of that budget moving over to the answer engines where discovery is increasingly happening. But there really isn't any incentive for retail media network leaders to concern themselves with this problem in the short term. Now that is a point of view that was also shared by Sam Curry at marketexture saying nearly the same thing on another podcast called adsn. And he said people are generally trying to hide a little bit from it and hoping that it just goes away. I've been making this argument for some time. I'll link up in the accompanying newsletter to some other thoughts that I've had on this topic. But I want to be clear. I'm not predicting the death of retail media. I've said it before and I'll say it again. Again. Sponsored product ads don't die. Off site media doesn't die. The endemic partner relationship doesn't disappear, but the surfaces over time will get reconfigured. The places where ad inventory lives right now needs to shift towards whatever proves to be durable in an AI mediated journey. And there are durable surfaces and there are durable assets that retailers have in store. Networks, post purchase touch points, loyalty programs. The moment when the shopper is really present in the retailer's ecosystem rather than just passing through. So the retailers who work on those durable assets and surfaces and the real shopper context that can't be disintermediated, those networks are really building for the future. But that is the alarm, and I'm sounding it now. This is just one part of a really great conversation that I had with James on his Yield Doctor podcast. If you want to check it out, I'll link up to it in the show notes. Thank you for listening, and I'll catch you tomorrow.
