Retail media market growth hits $184B as Amazon reaches $70B revenue

The scale of retail media now rivals traditional digital channels, forcing a reconciliation between trade marketing and brand advertising budgets. For the streaming ecosystem, the integration of Walmart and Amazon shopper data into DSPs like Google DV360 and Magnite transforms CTV from a top-funnel awareness tool into a closed-loop performance channel. As retailers like Amazon open their proprietary ad stacks to third parties, the industry must solve the fragmentation of having 200+ individual networks. Watch for the adoption rate of IAB Europe certification among smaller networks to see if standardized measurement can finally close the 53% attribution gap.

Amazon's advertising dominance continues to reshape how retailers approach their own ad platforms. In its most recent quarter, Amazon's advertising segment generated $13.9 billion in revenue, growing 19% year over year, a pace that outstrips most digital ad channels and pressures competitors like Walmart Connect to accelerate their own measurement capabilities. Walmart has responded by expanding its retail media operations internationally, with Walmart Connect now operating across 11 markets and integrating first-party purchase data into programmatic buying workflows that connect directly to demand-side platforms.

The measurement and standards gap remains the industry's most persistent friction point. At DTW Ignite in June 2026, Nokia announced partnerships with AWS and Databricks to build a unified data and control layer for autonomous network operations, a model that mirrors what retail media networks are attempting with their own fragmented data environments. The IAB Tech Lab has been working on OpenRTB extensions specifically designed for sponsored product ads, aiming to create a common transaction protocol that would allow retail media inventory to flow through standard programmatic pipes. Meanwhile, the Media Rating Council has extended its accreditation framework to cover retail media measurement, though adoption among the 200-plus individual networks remains uneven. Criteo has positioned itself as a neutral measurement layer across multiple retail media networks, offering cross-retailer attribution that attempts to bridge the siloed reporting problem.

On the technical side, the integration of retail signals into CTV and video is producing measurable performance gains. Nokia disclosed that its autonomous networks portfolio is delivering automation rates above 90% and service delivery times under four hours, benchmarks that illustrate the kind of operational efficiency retail media platforms are pursuing as they automate campaign optimization. The Trade Desk has integrated retail data partnerships into its Kokai platform, enabling advertisers to activate Walmart and Amazon shopper segments within CTV buys. Magnite, as a supply-side platform, has been working on standardizing how retail media inventory is packaged and sold programmatically, reducing the manual insertion-order processes that have historically slowed retail media adoption among brand advertisers accustomed to the self-serve efficiency of social and search.
