Although Tencent's cloud business has expanded rapidly and its paying customer base has grown, it is still a fair way behind Alibaba Cloud in China. For example, in the first half of 2018, Alibaba Cloud had a 43% market share of China's public cloud services market, followed by Tencent at 11.2%. So even if Tencent has managed to make up some of that ground (which is most likely has), the sheer size and breadth of Alibaba Cloud's offering mean its dominance in the cloud arena in China is set to continue in the short term.
