It’s unclear if there will be a revenue share on the sales made through the app. A Walmart spokesperson did not immediately respond to a request for comment.Tech giants and social media companies have been heavily investing in making their platforms more shopping friendly. Last year, Amazon launched Amazon Live, where hosts talk about and demonstrate products sold on Amazon. Google’s R&D launched Shoploop, and Facebook has made shopping more prominent on Facebook proper, WhatsApp and Instagram.But shoppable livestreams, akin to QVC, have struggled to take off in the U.S., despite their strong popularity in Asia. Walmart and TikTok’s shopping test run this week indicates they see opportunity and momentum in the space and want to make a mark early on.TikTok had already been making its way into the e-commerce space. The app began testing new social commerce features last year by allowing some users to add links to their profiles and videos. Retail giant Levi’s was among the first retail brands to use TikTok’s new “Shop Now” feature to direct users to merchandise.By teaming up with Walmart, both companies could boost their e-commerce operations, while giving the brick-and-mortar giant an edge with TikTok’s young user base. Walmart, which had been in talks to partly acquire some of TikTok’s operations, had indicated it wanted to bring shopping to the platform.”If you’re watching a TikTok video and somebody’s got a piece of apparel or an item on it that you really like, what if you could just quickly purchase that item?” Walmart CEO Doug McMillon told CNBC in October. “That’s what we’re seeing happen in countries around the world. And it’s intriguing to us, and we would like to be part of it.”Subscribe to CNBC on YouTube.
