Jack Ma, chairman of Chinese e-commerce giant Alibaba Group Holding, said on Monday he hoped the company's financial affiliate would list in Asia at some point, but that no decision on the timing or location had been made. The comments follow a Bloomberg report last week quoting unidentified sources as saying Zhejiang Ant Small & Micro Financial Services Group, known as Ant Financial, was planning an initial public offering (IPO) next year and the company had an estimated value of about $50 billion. "Ant Financial is still a baby today with great potential. It's just too early to talk about who it's going to get married to," Ma said. Asked if a listing would happen this year, he responded: "I don't think so." Set up in 2014, Ant Financial has been growing rapidly, largely through targeting smaller businesses and hundreds of millions of consumers who are often under served by China's larger banks. Ant runs the Alipay online payment platform, the linked Yu'e Bao money market fund and other services.
