E-commerce marketing · Industry brief

Retail media networks are undergoing significant structural transformation driven by AI agents and agentic commerce. According to multiple industry sources, agent-driven transactions are projected to exceed $9 trillion by 2028, representing 25% of global e-commerce flows. This shift requires retail media networks to evolve from monetizing human attention (via visual ads and clicks) to monetizing machine logic, moving from Cost-Per-Click pricing to Cost-Per-Recommendation models and charging brands for "Attribute Indexing" in retailer LLM databases. Meanwhile, the industry faces a maturity crisis. Forrester's "All Commerce Media Playbook" (commissioned by Koddi) surveyed 788 senior decision-makers and found the overall commerce media network maturity score at just 2 out of 5, despite 42% of leaders claiming "Advanced" programs. Only 13% qualified as true "Trailblazers." For CPG brands, retail media fragmentation costs roughly 20% in lost revenue—brands now manage 6 networks heading toward 11, with 33% of spend delivering ROI below 1x. Consolidation is accelerating: Bain projects roughly 50% of CPG companies plan to reduce network spending, while retail media is expected to capture 30% of all digital marketing spend within 2-3 years and 50% by 2030. Measurement credibility remains broken, with only 15% of brands trusting retail media attribution despite the channel capturing 30% of US digital ad spend. Amazon and Walmart account for 84% of US retail media spend, raising consolidation concerns as Walmart's $2.3 billion VIZIO acquisition signals retailers building larger, less transparent walled gardens. Separately, SEA's retail media networks are emerging as a $3 billion opportunity, with marketplaces showing only 2% ad depth compared to 7% in China, representing significant untapped monetization potential.
