Alibaba Group's Hong Kong shares closed down 10%, their biggest single-day drop in more than a year.
Some analysts said keeping the cloud unit could assist Alibaba's AI push.
But (it) also points to the increasing importance of retaining the cloud unit given the surging demand for AI computing in China," said US Tiger Research analyst Bo Pei.
Alibaba reported second-quarter revenue of 224.79 billion yuan ($31.01 billion), in line with the 224.32 billion expected by analysts, LSEG data showed.
The company also said it will press ahead with a listing of Alibaba's logistics arm, Cainiao, which applied for a Hong Kong initial public offering in September.
