Amazon and Walmart Pivot to AI-Driven Retail Rivalry

Retailers have long competed on product selection, price and delivery convenience. Generative AI is now shifting the battleground to the “decision layer,” where recommendation engines, conversational agents, predictive pricing and fulfillment systems jointly shape what consumers see and buy. Amazon is leveraging its end-to-end e-commerce and logistics network, while Walmart is combining physical stores with real-time inventory as they vie to control the shopping gateway and customer relationships.

Amazon launched agentic AI features for sellers on March 2, 2026, followed by the Amazon Connect Health administrative tool for healthcare on March 5, and announced a $50 billion investment in OpenAI. Walmart partnered with Google to provide free AI training to 1.6 million employees in the United States and Canada. It also plans to deploy digital shelf labels across 5,200 U.S. stores by 2027 to update prices and inventory.
