This past May, Walmart and DroneUp announced a major expansion to their network, promising to roll the service out to 34 new sites across six states and grow their coverage area by about 4 million customers.

An expansion to Virginia, where DroneUp is based, was announced in August. Then came the launch of services in Florida, Texas and Arizona and finally Utah.

Given the size of that coverage area, 6,000 deliveries might seem low. But compared to the competition, it’s a seemingly solid number: 2022 U.S. drone delivery figures from Prime Air and Wing are not currently available, but neither company can compete with Walmart’s coverage area.

Each is limited to operations in just two states: Both fly commercially in parts of Texas, while Prime Air operates a service in Lockeford, California, and Wing runs a pilot program in Christiansburg, Virginia. Of the two, Wing has had significantly more success internationally, having completed more than 300,000 deliveries globally to date.

While Walmart has yet to take its network abroad, the retailer shared some additional statistics that bode well for its U.S. service.

Not every Walmart store is equipped to make drone deliveries, but the company said it has 4,700 of them located within 90% of the U.S. population. In a way, the firm has a network of built-in fulfillment centers, any of which could be transformed into a drone hangar.

Another key stat: More than 85% of items sold at Walmart Neighborhood Markets fit the size and weight requirements for drone delivery. In total, the retailer and its partners are able to offer up to 20,000 items, making it an ideal candidate for such a service.

So far, no promises have been made around Walmart drone delivery for 2023. But if last year’s track record is any indication, the sky’s the limit.
