Alibaba's 18 founders, also known as the "Ali 18 Arhats", once held a 31.4% or 34% equity ratio. However, as time goes by and the company develops, the equity ratio may change. As the founder and core leader of Alibaba, Jack Ma once held 8.9% or 9% of the company's shares. Another co-founder, Joseph Tsai, held 3.6% or 6% of the shares. However, it should be noted that Alibaba's equity structure is relatively complex. In addition to the 18 founders, there are other shareholders, including Japan's SoftBank Group and Yahoo. Therefore, when considering the equity ratio of Alibaba's 18 Arhats, the impact of other shareholders needs to be taken into account. In addition, as Alibaba develops and raises funds, the equity ratio may also change. Therefore, the specific equity ratio needs to refer to the latest public information or official announcements. In general, the equity ratio held by Alibaba's 18 founders was relatively high in the early days of the company, but as time goes by and the company develops, the equity ratio may change.
