Recent movement from the U.S.'s biggest retailers into the primary care business indicates that the healthcare industry may be in for a big disruption—just like Uber overhauled the traditional taxi industry, according to an opinion article on Venturebeat.com.

Uber came out of nowhere and cashed in on the sharing economy—and in a short time the company hit a valuation of over $40 billion. Now Wall Street is searching for the next industry that can be Uber-fied, the article says. Walmart, Target, and Walgreens are just a few of the retailers to jump on the healthcare bandwagon.

War clouds? The article concludes: “There is no doubt that retail is making a big bet on health care. If it succeeds, the payoff will be enormous. But just as Uber is at war with the taxi industry, retailers will soon be at war with the large, publicly traded health care chains.”
