Joseph Tsai is a cofounder of Alibaba Group and ranks as its second-largest individual shareholder after Jack Ma. He rose from vice chairman to chairman in 2023 amid rising competition for the e-commerce giant. In 2024, five years after becoming the owner of NBA team Brooklyn Nets, Tsai sold 15% of its parent company BSE Global to American billionaire Julia Koch and her family for nearly $700 million. He holds two degrees from Yale University--an undergraduate degree in economics and East Asian studies and a law degree. Taiwan-born Tsai carries a Canadian passport.

“I knew I was in an environment to learn, so I didn't want to stick out. I knew I had a knowledge that nobody else had, so people could trust that aspect to me...I don't pretend to do everything. I knew what my role was [on joining Alibaba].”
