Retail Media Breakfast Club

Consumer AI is growing at an incredible pace, but here's the thing: even though millions of people are using AI, very few are actually paying for it. So how are these platforms going to make money, and what does that mean for retail media and the future of shopping?
In this episode, I'm digging into some fascinating new research from Andreessen Horowitz on consumer AI adoption, spending habits, and the business models emerging around these platforms. I explore why people are willing to pay for productivity but not necessarily everyday consumer queries, why advertising could become the dominant monetization model for AI agents, and what a potential ChatGPT wallet could mean for closed-loop measurement and retailers' first-party data. Plus, I look at the race to build the winning AI shopping experience and why retailers need to think carefully about whether to embrace or block emerging AI agents.

The retail media landscape is getting more crowded by the week. McDonald’s, Simon Property Group, Delta, and a growing list of other companies are launching commerce media businesses. But does the world actually need more retail media networks? In this episode, I share Matthew Fantazier's latest 'hot take' on the explosion of commerce media and add my own perspective on the biggest question facing these new networks: who is this actually for?
I also dig into the rise of consumer-facing AI agents and what it could mean for advertising, commerce, and consumer trust. If AI agents start making purchases on our behalf, who gets paid, how will brands compete for those transactions, and could paid placement quietly become the next evolution of retail media? There are some big questions ahead, and I’m not convinced we’re ready for the answers.

There’s a lot of talk in retail media about better measurement, incrementality, and finding the one metric that finally tells us what’s really working. But sometimes the metrics we’re using are… well, bulldust. In this episode, I dig into why measurement looks so different depending on which side of the table you’re sitting on, and why retailers and brands can both feel like they’re doing the right thing while talking completely past each other.
I also revisit the question of why ROAS refuses to die. Is it actually a useless metric, or does it persist because brands genuinely need a common currency and early signals to guide media planning? I look at sales lift, incrementality, MTA, basket lift and other signals — and why the real challenge may be less about finding a perfect metric and more about getting both sides to agree on what they’re actually trying to measure.

I recently took a closer look at what Best Buy Ads is building, and what it tells us about where retail media is heading. Best Buy was one of the early retailers to launch sponsored product ads, but at its latest showcase, that familiar ad format was barely part of the conversation. Instead, the spotlight was on connected TV, creators, TikTok Shop, its production studio, and new measurement capabilities.
I think that shift tells us something important about the future of retail media. Brands increasingly want retail media to do more than drive an immediate sale, while AI is changing how shoppers arrive at retailers in the first place. In this episode, I unpack why Best Buy may be looking beyond the traditional search-results-page model, what its new measurement research says about the brand-building potential of retail media, and why the retailers with the most distinctive assets may be best positioned to move beyond sponsored products.

A couple of years ago, two neighborhood cats started visiting our house. We fed them, they kept coming back, and then one day they turned up wearing collars that said, “Do not feed unless starving.” It turned out we weren't the only ones feeding them: and nobody really knew who was feeding them, how often, or how much.
Brands have their own version of this problem. When they add up all the attributed sales from every retail media network they spend with, somehow the total can come out bigger than their actual sales. So when Albertsons and Best Buy launched new multi-touch attribution (MTA) capabilities within a week of each other, I wanted to understand what problem they were actually trying to solve. Are brands really asking for MTA? Why did MTA fall out of favor in broader marketing? And has retail media simply never moved beyond last-click attribution? 
In this episode, I expand upon my recent article for The Drum, and dig into what brands, consultants and the retailers themselves are saying. I also set up the bigger question I'll tackle in Part 2: even if retailer-operated MTA is in the retailers' interests, can it still be useful and credible for brands?
