WeChat’s ability to create a bustling payments economy echoes the general success of its parent company. In September, Tencent became China’s largest company by value, surpassing state-owned China Mobile, when it reported its third-quarter revenue: $6 billion, up 52% year over year. How much of that can be attributed to Wallet and WePay was not specified: WeChat, China’s most popular messaging app, makes money largely from online gaming, advertising, and selling sticker packs. But Tencent—which began with the instant messaging app QQ and is now pursuing artificial intelligence and electric cars alongside investments in a range of companies, including China’s dominant ride-sharing operation, Didi Chuxing—did cite WePay as a major reason for its “other” businesses’ growth, which increased $726 million in the third quarter, or 348% over the same period last year. According to estimates by HSBC, based on current tech company valuations, WeChat could already be worth more than $80 billion, about half of Tencent’s market capitalization.
