From Insight to Action: How Walmart and Wiliot Are Building the Most Intelligent Supply Chain in Retail

A Smarter Supply Chain Takes Shape

Walmart’s large-scale partnership with Wiliot marks one of the most ambitious technology deployments ever attempted in retail. According to Supply Chain Dive, Progressive Grocer, and other industry outlets, the project is being extended to all 4,600 U.S. stores and more than 40 distribution centers. It is the first time ambient Internet of Things (IoT) technology has been implemented at this magnitude within a retail network.

Wiliot’s sensors, known as IoT Pixels, use Bluetooth Low Energy (BLE) to transmit real-time data on temperature, movement, and location. Unlike traditional RFID tags, these sensors are battery-free and harvest power from surrounding Bluetooth signals. They are embedded directly into the pallet labels that Walmart already applies in its distribution centers, which means there is no new step required for associates.

Each sensor continuously sends information to the cloud through existing wireless infrastructure, allowing Walmart to monitor products throughout their journey. The company can now see not only where a pallet is, but also how it is being handled and whether it is exposed to temperature or humidity risks.

As Wiliot’s Vice President of Solutions and Architecture, Nick Matthews, explained during an Omni Talk Retail Technology Spotlight interview, “We’re bringing intelligence to the things themselves, so the supply chain can think and act in real time.”

From Pilot to Nationwide Deployment

The program began with a pilot in Texas and expanded to hundreds of additional sites after showing strong results in accuracy and visibility. Early pilots demonstrated that the sensors could automatically identify misrouted pallets, detect when perishable goods were left outside refrigeration, and alert teams before issues led to product loss.

That success led Walmart to commit to a full-scale rollout, which will eventually involve tens of millions of connected pallets. As reported by the Financial Times, the system is now active in about 500 locations and will continue scaling through 2026.

For temperature-sensitive goods, the impact is especially important. The sensors allow Walmart to maintain continuous cold chain monitoring and generate digital records that help validate compliance with food safety regulations. The technology reduces waste and supports the company’s broader sustainability commitments by keeping more food in circulation and out of landfills.

Turning Data into Decisions

Beyond visibility, the true value of this deployment lies in decision-making. Data from Wiliot’s sensors feeds directly into Walmart’s artificial intelligence and analytics platforms, creating a live, digital view of the supply chain. This integration helps the retailer prevent disruptions, optimize routing, and plan replenishment with greater precision.

The measurable benefits include:

• Inventory Accuracy: Pallet-level data provides immediate insight into what merchandise is in motion and where it belongs.
• Cold Chain Protection: Continuous temperature sensing alerts associates before perishable items become unsellable.
• Labor Efficiency: Automated data capture reduces the need for manual scans and frees up associates for customer-facing work.
• Compliance and Traceability: Digital records of each pallet’s journey support regulatory and contractual requirements.
• Sustainability Gains: By preventing spoilage and misdirected freight, the system supports Walmart’s environmental objectives.

As Matthews put it, “The best way to solve a problem is to prevent it from happening in the first place.”

The Rise of Physical AI

Wiliot describes its mission as advancing “Physical AI,” a concept that brings artificial intelligence into the physical world of goods, equipment, and environments. Each sensor effectively turns an ordinary object into a data source, enabling AI systems to understand what is happening in real time rather than relying on historical trends.

For Walmart, this concept is now a reality. The retailer’s supply chain is becoming a dynamic, self-correcting network that learns from continuous feedback. According to Packaging Revolution and IoT Insider, this deployment signals that ambient IoT technology has matured beyond small-scale pilots and is ready for enterprise-level performance.

What It Means for Walmart Suppliers

The lessons extend far beyond Walmart’s own operations. Suppliers of all sizes can begin to explore similar ambient IoT applications without the need for massive infrastructure investments.

As Matthews explained, success depends more on focus than scale. “Start with one challenge and solve that. Once the data starts flowing, additional use cases become much easier to integrate.”

For suppliers, the potential advantages include:

• Better Collaboration: Shared visibility improves coordination between retailers and suppliers.
• Smarter Forecasting: Real-time data feeds more accurate demand models.
• Reduced Waste: Temperature and location tracking prevent product loss during transit.
• Improved Accountability: Automatic updates verify when and how products move through the supply chain.

Looking Ahead

While today’s focus is on pallet-level visibility, future expansions could bring even more granular tracking. Wiliot and Walmart have not announced a timeline for case or item-level sensing, but the groundwork is being laid through this large-scale deployment.

For now, the results speak for themselves. Walmart’s collaboration with Wiliot demonstrates how digital intelligence and physical logistics can work together to create a smarter, faster, and more sustainable supply chain.

For Walmart suppliers, it is a glimpse into where retail operations are heading and an invitation to start exploring the benefits of connected, data-driven inventory management.
