Commerce Media Hits 'Day Two': What's Next?
At the 2026 IAB Connected Commerce Summit (Apr 23, 2026), IAB argued that commerce media has moved beyond rapid expansion and must now prove its value. Growth is slowing, budgets face greater scrutiny, and many commerce media networks (CMNs) are undifferentiated. IAB published a work product, "Building A More Competitive Commerce Media Ecosystem," offering strategic paths for CMNs. The article identifies four 2026 imperatives: strengthen retail fundamentals before AI, scale in‑store media with reliable measurement, integrate retail media into core business functions, and provide transparent, validated measurement (including incrementality). IAB said it will publish an AI‑attribution playbook later in the year and formed a task force to standardize data inputs and reporting templates for data clean rooms to improve interoperability and budget allocation.
IAB's guidance signals a maturity shift in commerce/retail media; measurement, clean-room standards and business integration will influence budget allocation and which CMNs survive.

Commerce Media: Hype Fades, Brands Seek Maturity
An IAB blog summarizes a panel at the IAB 2025 Connected Commerce Summit where brand leaders from Coca-Cola, Nestlé, Boiron and Once Upon a Farm discussed the current state of commerce media. While IAB’s 2025 Outlook projected commerce media ad spend to grow 25.1% in 2024 (down 10 percentage points vs. prior year), the industry is moving from hype to maturity with uneven progress across companies. A live poll of 500 media professionals showed only 17% consider themselves "Advanced" while 83% are still developing capabilities. Panelists highlighted internal organizational barriers and a persistent lack of measurement standardization across retail media networks. Proposed responses included blended scorecards that combine short-term retail metrics with long-term brand signals and triangulation models linking campaign, category, and loyalty data.
IAB Warns Retail Media: Consolidation Ahead
Investors expect Netflix to emphasize content investment and advertising growth after walking away from a proposed Warner Bros. Discovery acquisition; analysts forecast Q1 revenue of $12.18bn (up 15.5%), including an estimated $634m from advertising, and note recent U.S. price rises may push users to ad-supported tiers. The Interactive Advertising Bureau launched the guide "Building a Competitive Commerce Media Ecosystem" at its Connected Commerce Summit in New York, laying out operating models, AI-driven commerce media guidance, measurement best practices and warnings that undifferentiated networks risk consolidation, as framed by IAB VP Collin Colburn. Separately, WPP is reportedly exploring a sale of its PR arm Burson, engaging Goldman Sachs advisers as part of its broader 'Elevate28' restructuring to cut costs and shift toward an AI-enabled operating model.
AI Visibility Requires English-Language Footprint for European Startups
This article discusses how the rise of generative AI and conversational search is changing B2B buying behavior, particularly for European startups targeting international markets. It highlights that with ChatGPT surpassing 900 million weekly users and 94% of B2B buyers using generative AI in purchase decisions, visibility in AI-generated answers is becoming critical. Traditional SEO is giving way to Generative Engine Optimization (GEO), which relies on a company's footprint across credible English-language sources. The article notes that most AI assistants evaluate live sources, favoring English content, and that smaller European languages constitute less than 0.6% of web content. It advises startups to build an international ecosystem of mentions, structure content for AI extraction, and maintain an equally strong English footprint. The piece underscores the importance of tracking share of voice in AI models.
