Zhang Yiming rose from Beijing’s tech circles to become China’s richest individual at 41, thanks to his proud stewardship of ByteDance and its global juggernaut, TikTok. Known for his reserved nature, Zhang stepped down as CEO in 2021, confessing he lacked “some of the skills that make an ideal manager,” yet remains central to shaping ByteDance’s AI ambitions.

While ByteDance’s global revenue surged by 30% to $110 billion in 2024, Zhang’s personal fortune climbed to an estimated $57.5 billion . Investors see him as a visionary who pivoted the company from content discovery algorithms to a sprawling AI infrastructure.
In 2025, ByteDance earmarked over ¥150 billion (~$20 billion) for capital investment—roughly half of it for overseas AI data centre expansion—backed by Chinese chipmakers Huawei and Cambricon, alongside compliant Nvidia GPUs under export controls. Zhang is said to personally negotiate deals for cloud-based access to Nvidia’s next-gen chips, signaling his hands-on approach to building global AI capacity.

ByteDance also launched the popular Doubao chatbot, which attracted around 75 million monthly users by early 2025, ranking it among the top AI apps in China. Still, analysts caution that fierce competition looms, especially from Alibaba and Baidu, despite Zhang outpacing rivals with unprecedented AI infrastructure investment.
On the geopolitical front, the U.S. Supreme Court is set to consider national-security legislation that could force a U.S. divestiture of TikTok, prompting Zhang to engineer strategies to maintain ByteDance’s global reach. Despite owning roughly 20% of the company, he navigates significant regulatory headwinds.

Quiet and contemplative, Zhang often prefers reading, coding and contemplating systems rather than public speaking. But behind the scenes, his strategic direction is fueling a transformation—ByteDance is not just a content platform now; it’s an AI infrastructure powerhouse with global ambitions.
