BREAKING DOWN RETAIL MEDIA'S VIBE SHIFT
Amazon and Walmart now control 85% of the retail media market. Walmart's $1.4B acquisition of Vibe widens that gap further. The deal mirrors Amazon's playbook of plugging first-party commerce data into a DSP and striking deals with premium streamers. Walmart has 200,000 Marketplace resellers it can immediately convert into CTV advertisers. For the 200-plus other retail media networks holding the remaining 15% between them, media planners aren't allocating budget to a third network after maxing out the top two, which makes data cooperatives or acquisition the only realistic paths forward.
