Symbotic Installs Its Next-Generation Fulfillment System In A Walmart Store

Symbotic has begun installing its next-generation SymMicro system in the back of a Walmart store. Rick Cohen, Symbotic’s chairman and chief executive officer, told analysts on the company’s third-quarter fiscal 2026 earnings call on August 5 that the system should be operating roughly six months from now. He declined to identify the store.

According to Symbotic, totes holding goods are retrieved from dense storage by autonomous mobile robots and delivered to a pick station where one operator fills multiple orders at once. Symbotic states that each station supports 550 picks per hour and that the arrangement removes online-order picking traffic from retail aisles.

Cohen also told analysts this is not the design Symbotic expects to build at scale.

The First Unit Is Built To Be Superseded

Cohen said Symbotic will overbuild the first system to make sure it works, then redesign it smaller and more efficient to hold down cost. He said the company probably will not build 400 of the version now going in, “but I think the one after this, we will.” A second site follows shortly behind the first, and Cohen said more sites should follow once Walmart sees the system working.

That sequencing carries a date. Izzy Martins, Symbotic’s chief financial officer, told analysts she does not expect the back-of-store order referenced in the Walmart contract to affect results until early 2028.

Symbotic’s filings treat the order the same way. The company’s third-quarter 10-Q describes the 400 automated systems as a contingent promise under the 2025 Walmart Master Automation Agreement, one that could add more than $5 billion to remaining performance obligation but is not carried as a committed amount. Symbotic’s $22.5 billion contracted backlog excludes those systems entirely. The structure was set at signing: under the January 2025 agreement, if performance criteria are achieved, Walmart is committed to purchasing and deploying systems for 400 Accelerated Pickup and Delivery locations over a multi-year period, with an option to add more later. Walmart is paying $520 million toward the development program, including $230 million at closing. Greg Cathey, Walmart’s senior vice president of transformation and innovation, said at the time that the arrangement would advance the company’s in-store pickup and delivery capabilities.

Nineteen Systems Are Already Running In Stores

Cohen said on the August call that Symbotic currently operates 19 of the older-version store systems. The prototype framing around the new installation obscures that. Walmart is not testing store-level automation for the first time, and neither company has said publicly what the redesigned version has to demonstrate before the 400 systems are ordered.

The lineage runs back further than the Symbotic agreement. Walmart began piloting in-store automated fulfillment in Salem, New Hampshire in late 2019, moved to acquire its technology partner Alert Innovation in October 2022, and formed an organization it named Walmart Advanced Systems and Robotics around that team. That is the business Symbotic purchased in January 2025. Walmart renamed market fulfillment centers to Accelerated Pickup and Delivery the same month, and APD is the term that appears in the Symbotic contract.

The Automated Backroom Holds Its Own Inventory

Symbotic describes SymMicro as digitizing inventory inside a secured robotic system. Reporting on the Bentonville Store 100 opening in 2023 described the earlier Alphabot generation the same way, as holding inventory separate from the sales floor. A store running one of these systems carries stock in two places, one pickable by shoppers and one held inside the robotic structure for online orders. Suppliers should consider whether their store-level on-hand view distinguishes between those pools, because a single blended number describes a store that may not operate the way the number implies.

Walmart has consistently framed the payoff in terms of substitutions. Its market fulfillment center announcements promised faster fulfillment with fewer substitutions, and Symbotic makes the same claim for SymMicro. A substituted line on a pickup order is a unit the ordered brand did not sell, decided by an associate rather than by the shopper who chose the item.

The deeper implication sits one layer back. David Guggina, then Walmart’s executive vice president of supply chain, told CNBC in 2024 that automated facilities let the company know what it owns, in what quantity, and where, in near real time, and that this precision let Walmart carry less safety stock. He was describing automated distribution centers, not store-level systems, and the statement should not be read as a claim about APDs. But it is the clearest account Walmart has given of why it buys this technology, and safety stock is where 1P suppliers feel automation first. The implication for replenishment and forecasting teams is that an operator with a cleaner inventory picture holds a thinner cushion, which raises the cost of a service failure even as it lowers the cost of carrying goods. Walmart has published no supplier-facing requirements tied to APD automation.

Third-party sellers get no direct exposure from this program. Walmart Fulfillment Services ships from dedicated fulfillment centers. Store backrooms sit outside that network, and nothing in the Symbotic agreement extends store-level automation to Marketplace inventory. The relevance for 3P is competitive, and it is conditional on scale. Nineteen automated backrooms change nothing about how a seller competes on delivery speed. Four hundred would, and that is the number worth watching.

Guggina became president and chief executive officer of Walmart U.S. on February 1, 2026, succeeding John Furner, who moved up to lead Walmart Inc. the same day. The executive who spent 2022 through 2025 deploying automation across Walmart’s supply chain, and then a year running its U.S. e-commerce business, now leads the division whose stores would house the 400 systems. Walmart said in January that it reaches roughly 95 percent of U.S. households with delivery in under three hours. The company reports second-quarter fiscal 2027 results on August 20, with Furner and chief financial officer John David Rainey hosting.
