How does Walmart use AI to manage its supply chain and inventory

The Core Approach: Localized Demand Forecasting

Walmart uses machine learning to forecast product demand at a localized level — by specific region, time of year, and even local events — rather than relying on generalized, one-size-fits-all demand estimates that don’t account for how demand actually varies by specific store location and circumstance.

The Measured Result

The company reports a 25% reduction in stockouts as a direct result of this improved, localized demand forecasting — a concrete operational improvement that translates into customers more reliably finding the products they’re looking for in stock.

Better Visibility Into Supplier Inventory

Walmart has also improved coordination with suppliers using technologies like RFID tagging and electronic data interchange, giving the company real-time visibility into supplier inventory levels and shipment status rather than relying on periodic, delayed updates.

A Unified View Across the Whole Supply Chain

More recently, Walmart has deployed agentic AI tools aimed at providing a single, unified view of inventory across stores, fulfillment centers, and other supply chain facilities simultaneously, rather than each location or system providing only a fragmented, siloed view of its own inventory.

Why Retail Supply Chains Are Well Suited to This Kind of AI Use

Large retail supply chains generate enormous amounts of structured, historical sales and inventory data, which is exactly the kind of input that demand-forecasting AI models perform well on — this is part of why retail has been an early, prominent adopter of AI-driven forecasting compared to industries with less consistent historical data to learn from.

Bottom Line

Walmart’s AI-driven supply chain approach centers on more accurate, localized demand forecasting and better real-time visibility across suppliers and facilities, with a measurable 25% stockout reduction as one of its clearest reported results.
