Walmart has contracted Wiliot to transform its supply chain operations. Millions of Wiliot ambient IoT sensors have been deployed across Walmart’s supply chain. Ambient IoT data is feeding Walmart’s AI systems to enhance supply chain efficiency, inventory accuracy, and cold chain compliance.

According to Wiliot, this is the first scaled roll-out of ambient IoT in the retail industry It is also one of the largest deployments of ambient IoT anywhere to date.

Wiliot’s IoT Pixels are being used to track Walmart pallets at scale, with a goal of reaching 90 million by the end of 2026.

The solution is currently deployed across 500 Walmart locations, with plans for national expansion in 2026. The roll-out will cover 4,600 Walmart Supercentres, Neighbourhood Markets, and over 40 distribution centres. It is generating high-resolution supply chain data that feeds into Walmart’s AI systems.

The collaboration is eliminating manual tasks and delivering automated alerts. This allows Walmart associates to act quickly, make smarter decisions, and dedicate more time to serving customers. Enhanced visibility has also helped resolve inventory discrepancies, ensuring smoother operations and improved customer experiences.

“With Walmart, we are advancing supply chain performance at an unprecedented scale,” said Tal Tamir, CEO of Wiliot. “This nationwide deployment adds a new layer of digitisation to Walmart’s supply chain, empowering associates with real-time insights and automation that drive greater efficiency, accuracy, and responsiveness. It’s a testament to the power of ambient IoT and artificial intelligence to help retailers operate smarter, move faster, and deliver stronger outcomes for their business, their associates, and their customers.”

“At Walmart, technology is in service of people – both our customers and our associates,” said Greg Cathey, Walmart Senior Vice President of Transformation & Innovation. “With Wiliot’s ambient IoT technology, coupled with our AI systems, we’re not only optimising our supply chain to make faster, smarter inventory decisions, but we’re also tackling one of the hardest problems in retail—knowing exactly what we own and where it is at any given moment. This enhanced visibility helps us deliver the consistent value, quality, and experience our customers expect – and that’s what drives us every day.”
