Something fundamental has changed in the relationship between brands and consumers. And most marketing departments have not yet reckoned with what it means.

For decades, brand building operated on a straightforward premise. A brand speaks. The consumer listens. The message, whether through a television commercial, a social media post, an influencer partnership, or a billboard, travels directly from the brand to the person it wants to reach. The brand controls the narrative. The brand chooses the words. The brand decides what story gets told.

That model is breaking down. Moreover, it is breaking down faster than most brand custodians are willing to acknowledge.

According to Envision Horizons’ 2026 AI Shopping Report, 63.1 per cent of US consumers have now used AI for product research, up from 49 per cent just a year earlier. A third use it weekly or more. Among those who shop with AI, 50.1 per cent have switched from a brand they normally buy because of an AI recommendation. Half, 50.9 per cent, have abandoned a purchase entirely after an AI assistant raised concerns about a product.

Half of AI-assisted shoppers have walked away from a product because an AI told them to. Not because of a bad review they stumbled across. Not because a competitor ran a better advertisement. Because a machine, which consumers trust more than the brand, raised a concern.

The traditional marketing funnel moved consumers from awareness to consideration to purchase. Furthermore, at every stage of that journey, the brand had the opportunity to intervene; to advertise, to reassure, to reframe. The brand was always in the conversation.

AI has broken that model by inserting an intermediary the brand cannot reach, cannot brief, and cannot control. When a consumer asks ChatGPT, Claude, or Google’s AI Overview what to buy, the brand does not get a seat at the table. The AI synthesises everything it knows: product reviews, third-party articles, online discussions, consumer complaints, ingredient lists, competitor comparisons, and delivers a recommendation based on its own assessment of what is trustworthy and relevant.

Only 9.8 per cent of consumers now choose a product based on brand name alone. Consequently, the decades of investment brands have made in building name recognition and emotional loyalty are increasingly insufficient as purchase drivers. Meanwhile, price is the most important factor for 34.7 per cent of consumers, followed by star rating at 26.2 per cent and familiarity at 12.2 per cent. These are factors that AI can assess and weigh without any input from the brand.

Thomas Walters, Chief Innovation Officer at Billion Dollar Boy, has articulated the shift with precision. “For years, marketers measured success through share of voice. In an AI-driven shopping world, the real battleground shifts to share of trust. Brands will compete not just for attention, but for recommendation credibility.”

That reframe is the most important strategic insight available to Nigerian brand managers and marketers right now. Share of voice was won through advertising budgets, media placements, and creative campaigns. Share of trust is won through an entirely different set of inputs: the quality and consistency of product reviews, the accuracy and completeness of product information online, the credibility of third-party sources that discuss the brand, and the authenticity of creator-led content that AI systems surface when building their recommendations.

Additionally, 45 per cent of active online shoppers now use AI tools like ChatGPT and Claude as part of their shopping journey to discover brands, compare products, summarise reviews, evaluate value propositions, and make purchase decisions. The consumer who once typed a query into Google now types it into a conversational AI. The consumer who once scrolled through retailer category pages now asks an AI to surface options. Furthermore, 39 per cent of AI users have tried brands they would not otherwise have considered, and 37 per cent buy more per order when AI is involved.

That last finding carries a genuine opportunity alongside the threat. AI is not just eliminating brands from consideration. It is also expanding consideration sets; introducing consumers to brands they would never have found through traditional discovery channels. The brands that will benefit from that expansion are the ones that have invested in being findable, credible, and accurately represented across every surface that AI systems read when forming their recommendations.
