You can usually tell when an episode is going to be good before you even hit record. This was one of those weeks. It came at the end of a long day, when the guard is down, the takes get a little sharper, and the conversation goes places you didn’t exactly plan for. That’s exactly what happened this week in London, when Ben Miller of Shoptalk joined me straight off the floor of the Retail Technology Show 2026.
Ben’s one of those rare operators who can zoom all the way out to macro industry shifts and then snap right back into the mechanics of how things actually work inside a business. It makes for a conversation that’s equal parts strategic and real, which is probably why we ended up covering everything from GLP-1s to Danny DeVito tattoos without missing a beat.
Here’s what we covered in this week’s Omni Talk Retail Fast Five, sponsored by the A&M Consumer and Retail Group, Mirakl, Ocampo Capital, Infios, Quorso and Veloq:
Walmart Is Betting Big on GLP-1s and Retail Should Be Paying Attention
Walmart’s move into GLP-1 weight management through its Better Care platform might end up being one of the most important stories of the year, and not just because it is Walmart.
Ben brought data to the table that honestly stopped me in my tracks. If GLP-1 adoption scales the way firms like Morgan Stanley are predicting, we are talking about a fundamental shift in how consumers eat, shop, and spend across entire categories. And the early data already shows it, with double digit declines in snack categories, meaningful changes in purchasing behavior, and a clear shift toward smaller, more functional, and more frequent purchases.
What struck me most is that Walmart is not waiting to react. It is building an ecosystem across pharmacy, telehealth, nutrition, and delivery that positions it right at the center of that behavioral shift. And if Ben is right, and he usually is on this kind of macro trend, the industry is still underestimating just how big this could get.
Starbucks and ChatGPT: Experimentation or Distraction?
This was easily the most debated topic of the episode.
Starbucks launching a beta experience inside ChatGPT sounds innovative on paper, personalized drink discovery, conversational ordering, all the buzzwords. But I’ll be honest, I’m skeptical.
My take was pretty simple. Just because you can build something in an LLM does not mean customers actually need it. Starbucks already has one of the best mobile apps in retail. So why introduce another layer of friction?
Ben pushed back in a really thoughtful way. His argument was not that this specific execution is perfect, he actually does not love the current experience either, but that brands do not really have the luxury of sitting on the sidelines right now. With 800 million people using ChatGPT weekly, the risk is not trying something and failing, it is not showing up at all.
Where we did agree is this: the current version probably isn’t the end state. There’s too much friction, and if anything, it raises bigger questions about menu complexity and operational strain inside stores. If you need AI to explain your menu, you might have a different problem.
Instacart’s Global Move Is About More Than Expansion
Instacart acquiring Instaleap might look like a straightforward international expansion play, but the more we talked it through, the more layers it revealed.
Yes, it gives Instacart immediate access to new markets and hard-to-build retailer relationships. But the bigger story might be what it does for the company’s long-term platform strategy.
Ben made a great point here. Grocery is won or lost on operational efficiency. Fulfillment, picking, and routing are where the battle is. And if Instacart can strengthen that foundation while layering in higher margin businesses like retail media on top, the model starts to look a lot more compelling.
I’ve been critical of Instacart in the past, but this is the kind of move that makes you pause. It’s not just about growth, it’s about building something more durable.
Walmart’s Private Label Redesign Signals a Bigger Shift
On the surface, a packaging redesign for Great Value doesn’t sound all that groundbreaking. Retailers update private label packaging all the time.
But timing matters.
Coming out of a period where national brands pushed price increases aggressively, the gap between branded products and private label has widened. And now, as inflation pressures start to creep back in, Walmart is making a very clear statement: we’re going to make private label not just cheaper, but more desirable.
The insight that stuck with me was this idea of pride. If customers don’t feel good about having your product in their home, there’s a ceiling to how much they’ll buy. Fixing that isn’t just about design… it’s about unlocking more frequency, more categories, and ultimately more loyalty.
And if Walmart gets that right at scale, it doesn’t just impact Walmart. It puts real pressure on every CPG brand in the market.
Aldi’s Quiet Power Move: Designing for Growth
Aldi might still be underestimated in the U.S., but it probably shouldn’t be.
What stood out in this story wasn’t just the expansion numbers (which are massive), but the idea of modular store design. That might sound like an operational detail, but it’s actually a strategic unlock.
As Aldi grows, especially through acquisitions and conversions, it can’t rely on a one-size-fits-all store format. Modularity gives it the flexibility to adapt to different footprints while still maintaining the efficiency that defines its model.
And if you zoom out even further, it raises an even bigger question: what happens if Aldi’s global operations become more unified over time?
If that ever happens, the scale advantage alone would be enormous.
