Alibaba is China’s — and by some measures, the world’s —biggest online commerce company. Its three main sites — Taobao, Tmall and — have hundreds of millions of users, and host millions of merchants and businesses. Alibaba handles more business than any other e-commerce company.


Alibaba is the most popular destination for online shopping, in the world's fastest growing e-commerce market. Transactions on its online sites totaled $248 billion last year, more than those of eBay and combined.


After it goes public, Alibaba is expected to be one of the most valuable tech companies in the world. It will also be one of the most valuable Chinese public companies, ranking among some of the country’s state-owned enterprises.
