Alibaba was originally founded by 18 people led by Jack Ma. After going public, except for some of the company's veterans who have some internal shares, most of the shares are locked in the hands of these 18 people.

As for being controlled by others, it is unlikely. But after the baptism of this financial storm, it is hard to say. Once someone raises more than half of Alibaba's current market value, it is hard to say.
