Walmart, the world’s largest retailer with $681 billion in annual revenue, over 10,500 stores in 19 countries, and a weekly customer base of 270 million, has long been a dominant force in the brick-and-mortar retail landscape. However, in the mid-2020s, the company found itself at a crossroads. The rise of e-commerce and the increasing dominance of online marketplaces had fundamentally changed the way people shop. To maintain its position as a retail leader, Walmart needed to not only embrace the digital revolution but also to redefine the very nature of the shopping experience. The company’s leadership declared that in 2026, “AI tinkering becomes transformation,” signaling a decisive shift from experimentation to full-scale deployment [3]. The company recognized that the future of retail was not just about selling products, but about creating seamless, personalized, and engaging experiences for its customers, both online and in-store.
The Challenge: From Transactional to Conversational Commerce
Walmart’s primary challenge was to bridge the gap between the physical and digital worlds and to create a truly omnichannel shopping experience. The company had made significant investments in its e-commerce platform and its delivery network, but the online shopping experience was still largely transactional. Customers would search for products, add them to their cart, and check out. While efficient, this process lacked the personalization and engagement of an in-store shopping experience, where a knowledgeable associate could guide a customer through their purchase.
Furthermore, the company needed to leverage its massive physical footprint to its advantage. With thousands of stores located within a short distance of a large portion of the US population, Walmart had a unique opportunity to offer fast and convenient delivery options that pure-play e-commerce companies could not match. However, to do so, the company needed to have a real-time view of its inventory across all locations and a sophisticated logistics network that could handle the complexities of last-mile delivery. The company also needed to prepare for the rise of “agentic commerce,” where AI agents would increasingly act on behalf of consumers to discover, compare, and purchase products [1].
Technology Implementation Workflow: The Universal Commerce Protocol and the Power of Gemini
To address these challenges, Walmart embarked on a landmark partnership with Google, announced at CES 2026, to create a new kind of shopping experience powered by agentic AI. The implementation workflow can be broken down into several key stages.
The first stage was the adoption of the Universal Commerce Protocol (UCP). The foundation of the partnership is the Universal Commerce Protocol, a new open standard developed by Google that is designed to enable seamless interaction between AI agents, merchants, and payment providers. The UCP is designed to facilitate the entire commerce lifecycle, from initial product discovery and search to final sale and post-purchase support. It provides a standardized way for AI agents to access product catalogs, check inventory, process payments, and manage orders, regardless of the merchant or the platform [2].
The second stage was the Integration with Google’s Gemini. Walmart has integrated its product assortment and its delivery network with Google’s powerful Gemini AI model. This allows customers to have natural language conversations with Gemini about their shopping needs, and to get personalized recommendations based on their past purchases and preferences. For example, a customer could ask Gemini, “I’m hosting a barbecue this weekend for 10 people, what do I need?” and the AI would generate a comprehensive shopping list of Walmart products, complete with prices and delivery options [1].
The third stage was the creation of an Agent-Led Commerce Experience. The partnership has created a new paradigm for e-commerce. In this new model, the AI agent acts as a personal shopper, helping customers to discover new products, compare prices, and make purchases. The agent can also provide helpful information about products, such as reviews, ratings, and nutritional information. Customers can complete their purchase directly within the Gemini app, without ever having to navigate to the Walmart website [1].
The fourth stage was the integration of Omnichannel Fulfillment. The integration with Walmart’s delivery network allows for fast and convenient fulfillment of orders. Customers can choose to have their orders delivered to their home in as little as 30 minutes, or under 3 hours for locally curated products, or they can pick them up at a nearby Walmart store. This leverages Walmart’s massive physical footprint to provide a level of speed and convenience that is difficult for pure-play e-commerce companies to match [1].
