I’m coming to you live from Shoptalk 2026 in Las Vegas, and this ep is packed with rapid-fire insights straight from the show floor. I pulled together six of the smartest voices in retail media to break down what’s actually happening right now beyond the buzzwords. From agentic commerce debates to Meta’s push into in-store data, we’re unpacking the trends that could reshape how brands and retailers work together.

We dig into the following: Is AI really going to change how we shop? Why are retailers expanding into offsite media in a more controlled way? And what role does content, especially video, play in the next phase of commerce? If you want a pulse check on where retail media is heading in 2026, this is one you don't want to miss.

In Part 4 of the Agentic Commerce Expert Series, we dive into one of the biggest emerging questions in retail media right now: what happens when ads enter AI experiences? With OpenAI and other LLM platforms beginning to experiment with advertising, there’s a lot of speculation (and skepticism) about how this will impact user trust, relevance, and ultimately, performance.

I’m once again joined by Amelia Van Camp from Mirakl, and together we unpack what “agentic advertising” really means, why relevancy is about to go into overdrive, and how both retailers and brands can prepare without guessing where formats will land. We also explore how data, intent-based attributes, and orchestration will shape the winners in this next wave of commerce. If you’re wondering how to stay ahead as AI reshapes the ad landscape, this one’s for you!

In August 2025 I broke down why so many retail media networks keep their ad tech stacks hidden. And to be honest, the reasons weren’t exactly flattering. But what happens when a major retailer does the exact opposite? In today's episode, I share highlights from my recent livestream with Mark Williamson, AVP of Retail Media at Costco, and Jon Flugstad, Chief Business Officer at MetaRouter, and unpack a bold move from Costco that’s turning heads across the industry: full transparency.

We dive into what really happened when Costco revealed its entire tech stack, why that matters for brands and agencies, and whether transparency is actually influencing ad spend, or simply generating buzz. Plus, I explore what this could mean for the future of retail media.
