(Reuters) – Alibaba Holdings Inc is in talks with major shareholders to reclaim a stake in fast-growing online-payments affiliate Alipay, The Wall Street Journal reported on Wednesday, citing people familiar with the matter. The discussions revolve around several options, among which is the purchase by Alibaba of one-third of Alipay, the Journal said, citing one of the unidentified people. Even if an agreement were to be reached, it would not be expected to take effect before Alibabas expected U.S. initial public offering, and it would face regulatory review in China, according the people quoted in the report. The Chinese company is now preparing for what could be the largest tech company IPO in history, a U.S. offering that is not expected to include assets related to Alipay.
