AI Chip Startup's Surge: A Tale of US-China Tech Tensions
A Chinese scientist named Chen Tianshi started a company called Cambricon that makes computer chips for artificial intelligence.
When the United States put restrictions on China's ability to get advanced computer chips, it created a supply gap.
The Chinese government encouraged companies to buy chips made in China, and Cambricon's sales grew very quickly.
Because of this, Chen Tianshi became very rich, and his company's stock price went up a lot.
Some people wonder if the company's success is mostly because of government help or if its chips are truly as good as others.
They also question if this fast growth can continue in the future.
Chen Tianshi's AI chip startup, Cambricon, has seen its shares surge, making him the world's 3rd richest under 40.
Cambricon's growth is attributed to US sanctions limiting China's access to advanced chips and Chinese government support for domestic AI.
The company's revenue has grown over 500% in the past 12 months, and its stock price has surged over 765% in the past 24 months.
Chen's wealth, mainly from his 28% stake in Cambricon, has more than doubled to $22.5 billion since the beginning of 2024.
Questions remain about Cambricon's valuation and its ability to compete with international leaders like Nvidia in the long term.

Cambricon's Growth and Valuation
Market Optimism Driven by Policy and Demand
Cambricon's significant revenue growth and soaring stock price are attributed to the urgent need for domestic AI hardware infrastructure, government mandates to 'buy local,' and investor enthusiasm fueled by US sanctions limiting access to foreign chips.
Market Skepticism on Sustainability and Competitiveness
Cambricon's rapid growth may be due to a low starting point and could be inflated without continued policy support. Its current valuation is questioned, and its chips might still lag behind international competitors like Nvidia, with success potentially more tied to political backing than pure market competitiveness.
Long-Term Prospects and Technology Ladder
Market Optimism Driven by Policy and Demand
The demand for domestic AI chips is strong, and companies like Cambricon are positioned to benefit from government support and a protected market, aiming to fill the supply gap created by US export controls.
Market Skepticism on Sustainability and Competitiveness
It is too early to determine if Cambricon can become China's Nvidia, as replicating Nvidia's full stack, including its CUDA ecosystem, is extremely difficult. Cambricon itself has acknowledged the challenges of climbing the technology ladder and remains under US sanctions.
