Episode notes
Episode 56 of The CMO Podcast with Fexingo. Lucas and Luna dive into the explosive growth of retail media networks - the digital ad platforms owned by retailers like Amazon, Walmart, and Instacart. They unpack why CMOs are pouring budget into these walled gardens: access to first-party purchase data, closed-loop attribution, and the ability to measure ad spend all the way to a cart. Lucas explains how retail media is reshaping the $600 billion digital ad market, citing Amazon's $47 billion ad business and Walmart's 30% year-over-year growth. They debate the trade-offs: higher cost per click vs. lower funnel certainty, and the risk of over-reliance on a single platform. The conversation also touches on the rise of in-store retail media via digital shelf labels and smart carts, and how smaller retailers are banding together in consortiums to offer scale. For marketers, the takeaway is clear: retail media isn't a channel anymore - it's becoming the new prime time.
