Locus Robotics vs Symbotic Depends on Rebuilding a Warehouse

Pick Locus Robotics for Existing Aisles, Symbotic for a Rebuild

Pick Locus Robotics if you want more picking throughput without rebuilding the warehouse, and pick Symbotic if you will commit to an engineered system that stores and moves cases and eaches. At The Bot Scout, we compared what each company publishes, and we did not test or measure either system.

Weigh one more fact before you pick Symbotic. Walmart accounted for approximately 85% of Symbotic's total revenue in fiscal 2025, according to Symbotic's Securities and Exchange Commission (SEC) Form 10-K. Symbotic lists that dependence on Walmart among its own risks.

Neither company publishes a price, so the table compares what each sells, what each needs from the building and what each has published about scale.

What Locus Robotics Sells

Locus Robotics sells a fleet of autonomous mobile robots (AMRs) on a robots-as-a-service (RaaS) subscription tied to the number of robots deployed. Customers pay for automation capacity and do not buy the hardware outright. Our robots-as-a-service explainer covers how that payment model works.

Locus keeps a human picker in the loop by deliberate design. A bot navigates to a picker, the picker places the item, and the bot carries it onward. Your associates handle the items, and the bots handle the travel between pick points.

Because the bots slot into an existing manual-pick workflow, a facility can add them without rebuilding the whole operation. The LocusBot fleet has three models:

• Origin: piece-picking for e-commerce items, with a payload of about 40 lb.
• Vector: general material handling, with a payload of up to about 600 lb (about 272 kg) and up to an 8-hour continuous runtime.
• Max: heavy-duty work, with a payload reported around 1,361 kg for pallet-scale loads.

Locus Robotics Scale and Company Record

Locus Robotics reports a fleet running at more than 350 sites for over 150 customers in retail, healthcare, third-party logistics (3PL) and industrial work. A mixed-fleet deployment called Locus Array combines bot types across one site on one warehouse execution layer.

The fleet passed 5 billion total picks in April 2025, 24 weeks after it reached 4 billion in October 2024. Locus also reports roughly $180 million in annual recurring revenue (ARR) by mid-2026.

Locus Robotics was founded in 2014 in Wilmington, Massachusetts, by Bruce Welty, Michael Johnson and Alastair Glass. It has raised more than $430 million in disclosed equity funding and is privately held as of 2026, with no initial public offering (IPO) completed.

Locus does not run its own fulfilment centres. Its bots work inside warehouses that third parties operate. Our Locus Robotics review and our autonomous mobile robots guide cover the fleet in more detail.

What Symbotic Sells

Symbotic sells robotic warehouse automation systems that store, move and sort cases and eaches, coordinated by AI software. The hardware and the software that runs it are sold together as one system. Symbotic's 10-K describes three parts:

• SymBot: an autonomous mobile robot that handles cases and totes and can travel above 20 miles per hour, per the 10-K.
• MiniBot: a robot that handles eaches.
• A storage structure: levels, transfer decks and aisles the robots work within.

Symbotic Scale, Customers and Backlog

Symbotic says its systems ship in excess of eight million cases per day without reported inaccurate fulfillments. That figure is Symbotic's own claim in its 10-K, and we have not verified it.

Symbotic reported a backlog of approximately $22.5 billion as of September 27, 2025. Agreements with Walmart and GreenBox, the venture trading as Exol, make up the vast majority of it, and $11.6 billion of the total is tied to GreenBox. The GreenBox agreement's initial term expires July 23, 2027, unless GreenBox uses its two-year extension.

The 10-K expects about 12% of the backlog to be recognised as revenue in fiscal 2026. That is roughly $2.7 billion (12% of $22.5 billion).

Symbotic's filings name several customers beyond Walmart, including a first healthcare customer signed in the quarter ended September 27, 2025. Our Symbotic company page covers the named customers and the filing figures. Our warehouse automation guide covers the wider category.

Walmart Concentration at Symbotic

Symbotic depends on Walmart for most of its revenue. Walmart accounted for approximately 85% of Symbotic's total revenue in fiscal 2025, per the 10-K for the year ended September 27, 2025.

Four other customers together made up about 13%. That leaves roughly 2% for every other customer combined (100 minus 85 minus 13). Walmart is both Symbotic's biggest customer and a shareholder.

Symbotic names this dependence itself, and its third-quarter fiscal 2026 release lists dependency on Walmart among its risks. Walmart's commitment to 400 micro-fulfillment systems also depends on those systems meeting defined performance metrics.

If you would be a smaller Symbotic customer, put the concentration on the table in quote talks. Ask Symbotic in writing who will staff your project, who supports your system after go-live and what delivery date it will commit to.

Prices Neither Company Publishes

Neither Locus Robotics nor Symbotic publishes a price, so you cannot compare the two on cost from public figures. Locus has no public price list or per-bot rate. It quotes each deployment on facility size, fleet mix, throughput targets and contract length.

A dollar figure for a Locus bot found online is an estimate, and Locus has not published an official rate. Expect a sales-engineering process with Locus before any figure arrives.

Symbotic's 10-K and its third-quarter release give no system prices. We have no independent throughput test of either system, so no public data supports a cost per pick. Put the same five questions to both companies so the answers line up:

• Price: the subscription rate for your fleet mix and contract length from Locus, and the system price from Symbotic.
• Building work: what has to change in your facility before the first pick or case moves.
• Throughput: what volume each company will commit to for your order profile, in writing.
• Performance terms: what happens if the system misses agreed metrics, the same kind of condition attached to Walmart's 400-system commitment.
• Support: who services the robots on your site after go-live.

Who Should Not Pick Each One

Skip Locus Robotics if you want to own robot hardware outright, because Locus sells capacity through a subscription. Skip it too if your goal is to take people out of picking, since Locus keeps a human picker in the loop by design.

Skip Symbotic if the aisles you have must stay as they are, because a Symbotic system includes its own storage structure of levels, transfer decks and aisles. Skip it if you will not accept a supplier that drew about 85% of fiscal 2025 revenue from one customer.

Skip both if you must budget from a published price this quarter, because neither company publishes one. For another picking option to price beside Locus, read our Geek+ review and our warehouse picking robots guide.

What Would Change the Locus Robotics vs Symbotic Verdict

The verdict rests on public company material, so four developments would move it:

• If either company publishes system or per-bot prices, compare the two on cost.
• If an independent throughput test of either system appears, weigh it above company claims, including Symbotic's eight-million-cases-a-day figure.
• If a later Symbotic 10-K shows Walmart's share of revenue falling well below 85%, the concentration warning weakens.
• If your volume justifies a fixed system and you can change the building, Symbotic moves ahead of Locus for case-and-each handling.

First Steps in a Locus Robotics vs Symbotic Check

Start by deciding whether you will change the building. If you will not, read our Locus Robotics review and prepare your facility size, fleet mix, throughput target and contract length for a quote.

If you will, read the filing figures on our Symbotic company page and contact Symbotic through its website. Send both companies the same five questions so your Locus Robotics vs Symbotic answers line up.
