Pulse Analysis

The 2025 retail media landscape has transitioned from a nascent channel to a sophisticated, data‑driven ecosystem. Marketplace sellers, once peripheral, now generate the bulk of ad spend, prompting platforms to build dedicated marketplaces‑first ad products. This shift mirrors broader e‑commerce trends where third‑party sellers dominate traffic, compelling retailers to treat these partners as core advertisers rather than ancillary participants.

Artificial intelligence has moved beyond experimental pilots to become the operating system underpinning campaign automation, audience segmentation, and real‑time bidding. AI‑powered recommendation engines now power agentic commerce, allowing shoppers to complete purchases through conversational interfaces and voice assistants. Brands that integrate these capabilities can deliver hyper‑personalised experiences at scale, reducing friction and boosting conversion rates across the funnel.

Product catalogues, traditionally back‑office assets, are now strategic infrastructure for discovery and monetisation. Rich, structured product data fuels search, recommendation, and ad targeting, turning inventory into a revenue‑generating asset. Coupled with full‑funnel expansion—where ads appear across search, social, and off‑site media—retailers can guide consumers from awareness to purchase without leaving the brand ecosystem. Companies that invest in catalog enrichment, AI orchestration, and marketplace‑centric ad solutions will capture the lion's share of retail media spend in 2026 and beyond.
