Companies like Amazon (AMZN) and Uber, once viewed as virtually unstoppable market disruptors, could well end up being disrupted themselves, according to a note by CLSA analyst Shaun Cochran.

Since their inception, Amazon and Uber have upended their respective markets: Amazon dramatically changed the online retail experience, forcing traditional brick-and-mortar stores to adapt or perish, and Uber transformed the transportation industry, offering a much more efficient solution to the long-established taxi system.

While Amazon has paved the way for data-driven, tech-heavy physical retail experiences through Amazon Go, its cashier-free grocery stores with 10 locations, some traditional brick-and-mortar retailers are making big strides to catch up.

This January, Kroger (KR) announced it’s partnering with Microsoft (MSFT) to “redefine” in-store shopping for customers. Kroger plans to deploy new technologies to two pilot stores in Ohio and Washington State, including an app that guides customers around the store to quickly find items, as well as digital price tags and promotions. Kroger plans on using customer purchase data, stored and crunched on Microsoft’s cloud-computing Azure platform, to sell digital ads and customized offers.

Kroger also signed a deal with Ocado, a UK-based online supermarket company, to order 20 automated customer fulfillment centers during the first three years of the agreement.

While that figure pales in comparison to Amazon’s 75 fulfillment centers in North America, Cochran praised Kroger’s efforts in his report published in early February.

“Efforts like these show that the retail incumbents finally get it,” wrote Cochran, who added that retailers now realize that consumers prioritize time and convenience over wandering around store aisles.

Disrupting the last mile

The tables could also turn on Uber, which has aggressively expanded in more recent years beyond its core ride-hailing business.

Uber’s food delivery service, Uber Eats, is reportedly on track to generate at least $1 billion in revenues this year, or between 7% to 10% of Uber’s overall annual revenues. But the company, which is expected to IPO later this year, could face increasing competition from several manufacturers looking to capture that so-called “last mile” — the last stretch of delivery between the fulfillment warehouse and a shopper’s doorstep.

“The emergence of last-mile delivery robots that take advantage of city-by-city opportunities for deliveries will continue this rising competition trend into Uber’s expansion markets, as well,” Cochran wrote.
