The In-Store Unlock: Retail Media's Next Stage | Behind the Numbers Special Edition
Why It Matters
Physical stores remain the primary touchpoint for product discovery and purchase, yet retail‑media dollars are funneled almost entirely into digital channels, leaving a huge efficiency gap. Solving measurement and organizational challenges could shift billions of ad spend to in‑store environments, reshaping how brands reach shoppers and how retailers monetize foot traffic.
Key Takeaways
- •Physical stores hold largest untapped retail media opportunity.
- •In‑store ad spend projected just over $1 billion by 2029.
- •Measurement integration is top buyer demand for scaling spend.
- •Retail media teams lack cross‑functional alignment and talent.
- •Amazon dominates 80% of retail media despite 6% sales share.
Pulse Analysis
Retail media continues its rapid ascent, with total U.S. ad spend topping $70 billion this year and projected to near $100 billion by 2029. While the channel now accounts for roughly one‑fifth of all digital advertising, the landscape is heavily skewed: Amazon alone captures about 80% of retail‑media dollars, even though it represents only around 6% of total retail sales. This concentration highlights a structural mismatch—advertising dollars flow where e‑commerce metrics are strongest, leaving the physical store, where over 80% of purchases occur, dramatically under‑served.
Buy‑side research reveals that more than half of retail‑media buyers already allocate budget to in‑store formats, yet total spend remains under 1% of the overall market, projected just above $1 billion by 2029. The primary barrier is measurement: nearly eight in ten buyers find it difficult to integrate in‑store results into existing dashboards, creating uncertainty and limiting budget growth. Advertisers are not demanding more inventory; they want comparable attribution and clean reporting that align with their digital KPIs. This measurement gap fuels a feedback loop—retailers hesitate to invest in in‑store infrastructure without clear demand, and advertisers stay cautious without standardized metrics.
On the supply side, retailers recognize the strategic importance of in‑store media, but internal alignment lags. Surveyed retail‑media leaders report a 30‑point drop between confidence in strategic direction and belief that the broader organization supports it. Cross‑functional coordination across merchandising, store operations, technology, and analytics is fragmented, and incentive structures remain tied to channel‑specific revenue rather than enterprise‑wide shopper outcomes. Breaking this cycle requires redesigning retail‑media architectures to accommodate physical‑store dynamics, establishing unified measurement standards, and aligning incentives across the entire retail ecosystem. Only then can the industry unlock the vast, untapped potential of in‑store advertising.
