Chen Tianshi, co-founder of Cambricon Technologies, transformed his AI chip company from near collapse into a multi-billion-dollar success, becoming one of the world’s wealthiest self-made entrepreneurs. In 2019, the company faced a severe crisis when its largest customer, Huawei Technologies, halted nearly all business to develop its own semiconductors, wiping out over 95% of Cambricon’s revenue. The company’s turnaround was catalyzed by the United States’ export restrictions on cutting-edge chips and Beijing’s concerted push to bolster domestic technology, which provided government backing and a protected market for Cambricon’s resurgence.

The financial impact of this strategic shift has been dramatic. Over the past two years, Cambricon’s shares have surged by more than 765%, and Chen’s wealth, derived from his 28% stake in the Beijing-based AI accelerator manufacturer, has more than doubled in 2025, reaching an estimated $22.5 billion, according to the Bloomberg Billionaires Index. This growth underscores China’s robust support for its domestic AI industry, giving rise to a new cadre of state-aligned tech elites amid restrictions on private-sector giants.

Despite the meteoric rise, analysts caution on the sustainability of Cambricon’s growth. Shen Meng, director at Beijing-based investment bank Chanson & Co, noted, “Cambricon’s explosive revenue growth is mainly due to a low starting point, and its current valuation may be inflated without sustained policy support.” Nevertheless, Chen stands as the third richest person under 40 worldwide, trailing only Lukas Walton and Mark Mateschitz.

A notable boost to both Cambricon’s shares and Chen’s net worth occurred in August after China reportedly advised domestic companies to limit use of Nvidia Corp.’s H20 processors, particularly for government-related applications. The company tempered expectations with a Shanghai Stock Exchange filing, emphasizing that it remains under US sanctions and highlighting the challenges of climbing the technological ladder, while dispelling rumors about non-existent products. Experts such as Sunny Cheung from the Jamestown Foundation advise caution, stating, “It’s too early to say if Cambricon or Huawei will become China’s Nvidia, as Nvidia’s CUDA ecosystem is extraordinarily hard to replicate quickly.”

Chen’s success reflects China’s state-backed academic pipeline, which has also fostered AI startups like DeepSeek, founded by Liang Wenfeng. Cambricon went public on the Shanghai Sci-Tech Innovation Board in 2020, initially struggling financially, but reported its first quarterly profits in the three months ending December 2024.

In 2022, the US Department of Commerce placed Cambricon on the entity list for its role in supporting China’s military modernization, restricting access to advanced Western technologies. Ironically, these restrictions, coupled with expanded export controls limiting Nvidia and AMD sales to China, created a substantial domestic supply gap. Beijing responded with “buy local” policies, mandating that domestic tech firms source critical chips from companies like Huawei or Cambricon. This surge in demand propelled Cambricon’s revenue by more than 500% over the past year, despite competition from Huawei and other startups. Shuman Ghosemajumder, co-founder and CEO of AI startup Reken, commented, “Their rise is directly caused by the urgent need for countries to have access to hardware infrastructure. Similar to Nvidia, they will likely encounter stock price variance as expectations are adjusted for generative AI models.”

Chen Tianshi’s journey exemplifies the interplay of government policy, strategic resilience, and market opportunity in shaping China’s emerging AI elite, highlighting how geopolitical shifts can unexpectedly create billion-dollar fortunes in the tech sector.
