Each business group and other investments will retain the flexibility to raise outside capital and seek an initial public offering, Alibaba said in a statement.
Alibaba shares fell as much as 9% on Tuesday after a state media report that Chinese authorities had taken action against an individual surnamed Ma, but recouped losses after the report was revised to make clear it was not the company's founder.
Alibaba raised its share buyback programme to $25 billion on Tuesday, the largest ever repurchase plan by the e-commerce giant, to prop up its battered shares as it fights off regulatory scrutiny and concerns about slowing growth.
