Walmart uses AI to limit weather supply disruptions
Walmart is using predictive artificial intelligence and machine learning to mitigate weather-related disruptions across its supply chain. The company combines historical weather patterns, real-time forecasts and operational signals (transportation capacity, employee availability, carrier data) to simulate impacts, reposition inventory, reroute shipments and recalculate fulfillment paths before storms, wildfires or other severe events. Walmart also uses smart tracking to monitor shipments in transit and communicate delivery changes to customers. Walmart Canada developed a storm rerouting agent that cross-references 10-day forecasts with highway/ferry closures and carrier signals to improve visibility in remote regions. The article quotes Indira Uppuluri, Walmart's senior vice president of supply chain technology, and was published July 30, 2026 on Retail Dive / Supply Chain Dive.
Major global retailer applying AI to operational resilience is notable for logistics and retail systems but is not industry-shifting for AdTech/MarTech.

Walmart Uses AI and Digital Twins for Supply Chain
Walmart is expanding its use of artificial intelligence and digital twin technology to optimize global supply chain operations, according to Indira Uppuluri, the company’s senior vice president of supply chain technology. The retailer uses predictive models, machine learning, AI agents and virtual replicas of its logistics network to simulate disruptions (facility closures, transportation delays, shifting demand) and recommend actions for associates. Walmart also provides role-specific AI certifications in partnership with OpenAI and Google via its associate-facing platform, Squiggly, and builds custom AI tools internally. The approach is intended to improve assortment, speed and cost trade-offs amid geopolitical, tariff and weather-driven supply chain volatility in 2026.
Walmart Uses AI Cameras to Monitor Stores
Walmart is deploying an AI-powered camera system across its stores to monitor floors, shelves, and checkout lanes in real time, with alerts and tasks pushed to associates via the MyWalmart app. The system detects missed scans at self-checkout, triggers restocking tasks when shelves are low (including produce ripeness assessment), and continuously monitors for safety hazards like spills or malfunctioning refrigerators. While aimed at reducing inventory shrink and improving operational efficiency, the system has generated false positives, particularly with spill detection, though accuracy is improving with model retraining. The deployment reflects a broader retail trend of turning existing camera infrastructure into sensor networks, but raises surveillance concerns among workers and labor advocates.
Walmart Trains Store Employees to Use AI
Walmart has begun certifying store-level associates to use generative AI through partnerships with OpenAI and Google. The company launched an OpenAI certification program last week, following an earlier Google certificate, to teach AI fluency, responsible use, and how to keep human judgment central. Walmart executives say the training is personalized by role — from basic confidence-building for AI newcomers to operational uses for merchandising, scheduling dashboards for store managers, and apps for logistics. Examples include an associate-built bakery app that evaluates cake decoration from photos and a logistics tool that helps drivers pick loads to get home on time. Walmart is also limiting redundant AI use cases where costs outweigh benefits.
