Walmart's Automation of About 200 Warehouses Faces Technical Setbacks, Major Partner Symbotic's Robots Frequently Malfunction
Walmart's push to automate about 200 supply chain facilities in the U.S. is facing ongoing technical and operational setbacks, with frequent malfunctions of robots from its main partner Symbotic, in which Walmart holds a 12.6% stake.
Robots have been shut down due to dust accumulation, failures in handling oversized items like large bags of dog food and frozen turkeys, and boxes exceeding a height of 1.5 inches, leading to incompatibility; at some testing sites, only about 80% of inventory has been automated.
A Symbotic spokesperson stated that the repair rate for robots has decreased from under 10% last year to about 5%, but the company still struggles to meet throughput targets. Maintenance requires high-salary engineering talent, and the monthly peak electricity costs for some automated warehouses exceed $800,000, far higher than the $250,000 for manual warehouses.
Since 2016, Walmart has invested nearly $1 billion in in-store automation, having previously acquired Alert Innovation and sold it to Symbotic at a loss, while also paying an additional $520 million to complete related system development, with a new test version expected to be available by 2028.
Amazon leads in warehouse automation and has surpassed Walmart to become the largest company by annual revenue in the U.S., increasing pressure on Walmart to accelerate delivery. The supply chain head stated that they are currently at a "peak of complexity."
In market dynamics, Walmart is both Symbotic's largest customer (accounting for about 85% of its revenue) and a shareholder, meaning that the costs of malfunctions primarily fall on Symbotic, while Walmart benefits from successes; independent automation suppliers and manual warehouse workers are under pressure, while Walmart locks in its technological path through shareholding and order commitments.
The renovations mainly target outdated warehouses from the 1980s and 1990s and are being carried out during ongoing operations, with progress lagging behind original targets.

Walmart and Symbotic have collaborated to advance the automation of regional distribution centers since 2015-2017, later expanding to all 42 centers and acquiring Walmart's internal robotics department, continuing the retailer's practice of binding a single supplier through shareholding and large orders.
Capital has entered Symbotic through shareholding and $520 million in development funds, with Walmart accounting for about 85% of its revenue, focusing resources on high-density storage robots to enhance throughput, motivated by the need to catch up with Amazon's delivery speed and reduce long-term labor costs.
This is similar to Amazon's early acquisition and internalization of Kiva or the deep binding of retailers to a single technology partner. Currently, it is in a phase of expanding from pilot to large-scale transformation but is constrained by physical limitations, prioritizing the adaptation of old facilities over new construction.
Essentially, this involves technological substitution and industrial chain restructuring: automation attempts to convert manual handling into robotic processes, but variations in the physical world (size, dust accumulation, abnormal products) expose the limitations of software assumptions. The mechanism is that customer concentration and equity binding externalize malfunction costs to suppliers while locking in technological paths, increasing switching costs and delaying replacement speed.

The physical world is harder to automate than software.
Holding shares in a supplier does not equal control over progress.
The larger the scale, the more complex the transformation.
