Amazon and Walmart are racing to dominate the emerging AI-driven "decision layer" in retail, which uses recommendation engines, conversational agents, and dynamic pricing to influence what consumers see and buy. Walmart leverages its physical stores as fulfillment hubs to integrate real-time inventory with AI for faster, reliable delivery, while Amazon uses its end-to-end automated commerce system to optimize product discovery, pricing, and delivery. This shift means winning in retail depends less on product assortment or price alone and more on controlling the AI systems that guide consumer decisions, posing new challenges and opportunities for retailers. The outcome will shape the future of personalized shopping and fulfillment speed.
