How AI helped Walmart go from 700,000 to 60 million items online

Walmart.com is bigger than you might think. The site has 60 million items for sale, Walmart CTO Jeremy King said at the VB Summit in Berkeley, California today. That's up from 700,000 items when he joined Walmart in 2011, and it doesn't include Jet.com, the ecommerce site Walmart acquired last year. Online sales have also made notable gains: The company reported a 67 percent year-over-year increase in quarterly online sales for the three months ending in June of this year. The secret to the expansion in inventory, said King, is artificial intelligence.
