Walmart Scales Wiliot Sensors to Strengthen Inventory Tracking and AI Capabilities
Walmart is expanding its investments in inventory tracking technologies to make its supply chain more visible and intelligent. The retail giant is partnering with Wiliot to deploy ambient IoT sensors throughout its supply chain, broadening automation and real-time data usage across inventory management, cold chain operations, and beyond.
Walmart's objective is clear: deliver faster, more accurate, and more efficient inventory management to further strengthen its AI-powered supply chain.
Sensors Active in 500 Stores — National Scale by 2026
Wiliot sensors are currently deployed in 500 Walmart stores.
The plan:
4,600 stores by end of 2026,
40+ distribution centers,
Indirectly equipping millions of pallets and cases with sensors.
This technology is a cornerstone of Walmart's goal to achieve near-complete IoT visibility across its U.S. supply chain network.
How Ambient IoT Sensors Work
Wiliot's small, low-cost sensors that harvest energy from their environment are called Pixels.
These sensors:
Monitor product levels on pallets,
Track location changes,
Monitor temperature and environmental conditions (particularly critical for cold chain),
Automatically track movement from distribution center to store.
Wiliot President Julien Bellanger emphasizes that these sensors are particularly critical in cold chain operations:
"It's vital to ensure that products reaching stores are quickly placed in refrigeration."
Additionally:
Sensors eliminate manual scanning,
Positive delivery verification becomes fully automated,
Enables shared visibility between supplier and Walmart.
With AI: Major Reduction in Inventory Errors
Walmart feeds data from sensors directly into AI-powered inventory management systems.
This enables:
"What products do we have?"
"Where are they located?"
"Are stock levels actually accurate?"
to be answered in real time for the first time.
Walmart SVP Greg Cathey summarizes the partnership:
"Through ambient IoT and AI integration, we're making faster and smarter inventory decisions.
We're solving retail's toughest problem: knowing when, where, and what we have."
Case-Level Tagging: The Next Step
Walmart currently uses sensors at the pallet level; however, Wiliot's goal is case-level tagging.
When this transition occurs:
Inventory accuracy will increase further,
Shrinkage and loss rates will decrease,
Replenishment processes will become more automated,
Manual workload for store employees will be reduced.
Bellanger:
"Our goal is to reach case-level tagging. This will completely transform Walmart's inventory visibility."
Operational Efficiency Gains
Wiliot sensors also reduce workload for Walmart associates:
No manual scanning
No paper processes
No unnecessary checks
Cold chain breaches are instantly caught with automated alerts
This enables teams to focus on higher-value activities:
Product placement
Replenishment
Customer service
Strategic Takeaway: Walmart Accelerates in the "AI-Powered Supply Chain" Race
Walmart is expanding its AI investments beyond software alone, embedding them in physical supply chain infrastructure through sensors.
With this technology:
Out-of-stock rates decline,
Overstock situations decrease,
Replenishment cycles accelerate,
Cold chain errors are minimized.
This enables Walmart to strengthen both its cost advantage and customer experience.
Key Takeaways:
Walmart is scaling ambient IoT sensors nationally through its Wiliot partnership.
By 2026, 4,600 stores and 40 distribution centers will be covered.
Sensors eliminate manual scanning and enhance cold chain compliance.
Data is directly integrated into Walmart's AI systems.
Goal: Full visibility through case-level tagging instead of pallet-level.
For Walmart, this technology creates strategic advantage along the inventory accuracy + speed + cost axis.
