The digital commerce landscape is on the cusp of its most significant transformation since the advent of the smartphone. This evolution is being driven by the rise of ‘agentic commerce,’ a paradigm in which artificial intelligence agents operate on behalf of consumers to navigate the complex digital marketplace. A recent report from McKinsey & Company has shed light on this emerging trend, describing a future where the consumer’s purchase journey may bypass traditional brand and retailer interfaces entirely. Instead, it will be mediated by sophisticated AI agents that can compare products, evaluate reviews, and even negotiate prices, all with minimal direct input from the human consumer. This fundamental shift in who controls the shopping journey has profound implications for brands, retailers, and the entire ecosystem of digital marketing and sales.
The McKinsey report outlines two distinct ‘entry points’ for this new form of commerce. The first is through retailer-specific AI tools. For instance, a consumer shopping on Amazon or Walmart might deploy the platform’s built-in AI assistant to find the best product for their needs. The second, and arguably more disruptive, entry point is directly within a generative AI platform. A consumer could ask a standalone AI chatbot like ChatGPT or Google’s Gemini to find the best running shoes for under $150 that are suitable for wide feet and have excellent arch support. The AI would then independently search across the web, analyze product specifications, read user reviews from multiple sources, and present a synthesized recommendation. In both scenarios, the traditional funnel of brand awareness, consideration, and purchase is collapsed into a single, automated query-and-response interaction.
This shift is already being reflected in consumer behavior data from the McKinsey study. It indicates that 28% of Gen Z consumers have already used generative AI tools in their shopping process, while 23% of all consumers are discovering new brands through social media, often in ways that are algorithmically curated and personalized. These figures are expected to grow rapidly as the technology matures and becomes more integrated into everyday digital experiences. The implication for brands is stark: their carefully constructed narratives, advertising campaigns, and brand websites may no longer be the primary touchpoints for influencing a consumer’s decision. Instead, the AI agent becomes the new ‘customer,’ and the brand’s goal shifts from persuading a human to being selected by an algorithm. This requires a fundamental change in marketing strategy and content optimization.
One of the most critical findings in the McKinsey report is the data source imbalance in generative AI responses. The report reveals that generative AI models draw approximately 99% of their information sources from third-party signals such as review sites, forums, and social media, with only about 1% coming directly from brand-owned websites. This means that a brand’s official product page, no matter how well-crafted, has a tiny influence on what an AI will ultimately say about that product. The overwhelming majority of the AI’s ‘knowledge’ is derived from user-generated content, expert reviews, and independent discussions. Consequently, managing a brand’s reputation and narrative in these third-party environments becomes paramount. A brand can no longer simply control its own message; it must actively cultivate a positive and accurate presence across the decentralized web of consumer discourse.
This requires a proactive and strategic approach to what might be called ‘signal management.’ Brands must engage with customers on review platforms, respond to feedback, and ensure that their product information is consistently and accurately represented across the web. This also involves optimizing for how AI models index and interpret information. Just as SEO was about making a website discoverable to search engine crawlers, the new discipline involves making a brand’s narrative discoverable and ‘trustworthy’ in the eyes of AI algorithms. This means investing in high-quality, authentic customer experiences that generate positive reviews, as these are the signals that AI models are most likely to weigh heavily in their recommendations. A brand cannot ‘trick’ an AI, but it can ensure that its genuine value proposition is clearly and consistently reflected in the data sources the AI relies on.
The major commerce platforms are already preparing for this agentic future. Shopify, Amazon, and Walmart are actively developing universal standards and APIs that will allow AI shopping agents to interface directly with their platforms. This will enable agents to not only find products but also to complete purchases, track deliveries, and process returns. For brands, this means they must decide strategically where and how to participate in this new ecosystem. Being present on the major platforms that are building these agentic interfaces will likely become a requirement for visibility. However, brands may also need to consider the risk of disintermediation, where the direct relationship with the consumer is entirely mediated by the AI agent. In such a scenario, brand loyalty could erode as consumers increasingly rely on agents to make ‘optimal’ choices, potentially turning products into fungible commodities.
In conclusion, the rise of agentic commerce represents a paradigm shift that challenges the fundamental assumptions of digital marketing and brand management. The consumer journey is no longer a linear path but a dynamic interaction that is increasingly automated and intelligence-driven. To thrive in this new environment, brands must adapt their strategies on two fronts. First, they must optimize their digital presence for AI discovery, ensuring that their products and narratives are accurately represented in the data sources that AI models trust. Second, they must actively manage their reputation on third-party platforms, cultivating the positive signals that will influence AI recommendations. The future of commerce is agentic, and the brands that embrace this reality will be the ones that survive and prosper in the years to come.
