Retail media networks have quietly become one of the most important forces in advertising.
In this episode, Kelly and Sean break down what retail media actually is, why it’s growing, and where it may be heading next.
At its core, a retail media network allows retailers to sell advertising using their own customer data—whether that’s on their website, app, or even in-store screens. Companies like Amazon, Walmart, and Target are leading the way, using shopper behavior to deliver highly targeted ads.
But the real story is in the growth.
Retail media accounted for roughly 15% of total U.S. media growth last year, making it one of the most impactful drivers in the industry.
So why is it working?
Two major factors:
High purchase intent – Ads reach consumers already in buying mode
Closed-loop measurement – Platforms can directly connect ad exposure to purchases
From an advertiser perspective, that combination is hard to ignore.
The episode also explores how the space is evolving:
Key trends shaping retail media
Amazon continues to dominate, driving about 40% of retail media ad revenue
Traditional retailers like Walmart, Kroger, and Target remain strong
New entrants—like Uber, Instacart, and airlines—are entering the space
Over 50 large-scale retail media networks now exist in the U.S.
At the same time, signs of maturity are starting to appear:
Fewer new network launches in 2026
Slowing user growth as adoption approaches saturation
Increased competition for the same audiences
So where does growth come from next?
Sean outlines three emerging directions:
Offsite advertising – Using retail data to sell ads beyond owned platforms
Audience matching & data partnerships – Expanding targeting capabilities
Continued expansion from existing players – Rather than new entrants
The takeaway: retail media isn’t slowing—but it is changing.
