BCG study: AI becomes top influence on purchases
A Boston Consulting Group (BCG) study cited by Retail-News finds artificial intelligence is rapidly gaining importance in consumers' purchase decisions. Roughly 31% of consumers already use AI during some phase of the shopping process, and respondents expect trust in AI to increase by 15 percentage points by 2030. About 19% are identified as “AI-loyalists,” and roughly 70% of those subsequently purchase products recommended by AI. The study also reports that more than half of consumers do not fully trust any single information source, that AI drives discovery of previously unknown brands, and highlights structural retail trends such as the rising share and spending power of single-person households in developed markets.
The BCG study indicates AI will substantially change brand discovery, recommendation and purchase behavior — implications for retail media, ad targeting, measurement and marketers' ability to influence conversions.

AI Shopping Adoption Grows, But Trust Limits Transactions
New data reported by MarTech from Exploding Topics (May 1, 2026) shows widespread consumer use of AI in shopping—77.6% used AI for shopping in the past six months and over 43% used it weekly—but a clear trust ceiling prevents AI from completing purchases. About 68.64% of users say AI influenced a purchase they otherwise would not have made, yet more than half of consumers are uncomfortable with AI storing payment card details and most would allow AI to spend $0 autonomously (frequent users typically cap autonomous spend at $50 or less). The findings imply AI is established as a decision-layer for research and consideration, while transactions remain under human control, increasing the importance of visibility in AI-generated recommendations and generative engine optimization for marketers.
AI Shopping Goes Mainstream: 2026 Key Stats
A July 28, 2026 MarTech article aggregates 2026 research showing rapid consumer adoption of AI tools for shopping research. Key findings: substantial portions of U.S. consumers use AI assistants for product research (43%) and many begin purchase journeys on AI platforms (46%). AI-sourced traffic to retail sites surged dramatically (Adobe reports a 1,200% YoY increase), and AI-referred shoppers convert at higher rates. Most consumers verify AI recommendations through other sources, and organizations report both strong expectations for agentic AI handling customer interactions and gaps in cloud readiness. Category usage is broad (travel, electronics, finance) and projections estimate agentic shoppers could account for $190–$385 billion in U.S. ecommerce by 2030. The piece synthesizes data from Product.ai, L.E.K. Consulting, Adobe, NielsenIQ, Gartner and others to highlight consequences for marketing, traffic, conversion and CX strategies.
Criteo Report: AI Aids Shopping but Stops Before Checkout
Criteo's "2026 Commerce & AI Trend Report," based on a January–February 2026 consumer survey of 6,379 people across the US, UK, Germany, France, Japan and South Korea, finds AI increasingly central to product discovery but rarely completing purchases. Marketplaces (36%) and search engines (28%) remain the dominant search entry points; AI assistants account for 14% as a complementary channel. Consumers use AI mainly for research and comparison—nearly half use AI tools for product comparisons while only 8% report buying through those tools. Visual (44%) and voice (26%) search are rising, and respondents prioritize a mix of personalization and unexpected discovery. Trust factors—privacy (46%) and protection against manipulated content (52%)—and strong brand recognition (75%) remain decisive for completing purchases.
