From Aisles to Algorithms

How AI Is Redrawing the Rules of Retail

We previously looked at how consumers are becoming more intentional in their purchasing decisions – timing their buys around promotions and spending more than planned when the moment is right. 

Zooming out to the bigger picture, we observe the volatile market environment that is shaping this behavior, and what it means for brands navigating the shift from physical shelves to digital algorithms.

Fragmentation: Retail Without a Fixed Path

The most important shift, however, is happening beyond the shelf. Retail is no longer a linear path from awareness to store visit. Consumers now move fluidly across e-commerce, social commerce, quick delivery, physical stores, and increasingly AI-powered research, curating their own journey in real time. In 2025, online TCG-revenue grew 8% versus 3% offline. 18% of consumers bought directly through TikTok Shop, and 16% frequently used quick-delivery apps. All signs that discovery and conversion are fragmenting fast.

AI as Decision Engine: Get Shortlisted or Get Lost

AI now pushes that fragmentation into an entirely new phase. Already 10% of consumers use AI search in their purchase journey, and that share is forecasted from the 12% in Q4 2025 alone. As shoppers use AI to compare models, summarize reviews, understand specifications, and identify the best offers. AI is no longer just a novelty touchpoint; it is becoming a decision engine that shapes what gets shortlisted before a consumer ever reaches a retailer website or a store aisle.

That changes the competitive game. If the shelf now extends into algorithms, then product pages, specifications, claims, reviews, and content architecture must be built not only for people, but also for AI systems that parse, compare, and recommend. The winners in 2026 will not simply be the brands with the broadest assortment or the loudest promotions – but the ones that make decisions easier in a world where the consumer arrives informed, intentional, and increasingly advised by machines before the store even opens.

“In the age of agentic AI, the roles of consumer and shopper are increasingly diverging, where one becomes the entity experiencing the purchase and the other the one that makes the purchase.“ Nevin Francis, Senior Director / Global Strategic Insights at NIQ.
