On the 27th, the application developed by Chinese AI company DeepSeek reached the top of the free download rankings on the U.S. app store, marking a significant shift in the competitive landscape of the AI market.
Following this news, NVIDIA's stock price temporarily plunged by 17%, symbolizing the market's reaction. This decline resulted in a loss of approximately $600 billion (about ¥92 trillion) in market capitalization, marking the largest drop in NVIDIA's history.
On the same day, U.S. stock markets saw widespread selling of AI infrastructure-related stocks, and Japan's Nikkei 225 index continued to fall on the morning of the 28th, with the decline exceeding 600 points at one stage. This risk-off sentiment also extended to the cryptocurrency market, causing Bitcoin to drop nearly 7% from $105,000 to around $97,600.
This market reaction highlights concerns that DeepSeek's ability to develop high-performance AI models at low cost could reduce demand for high-end chips produced by companies like NVIDIA. Additionally, shaken investor confidence in NVIDIA's existing technology further accelerated the stock's decline.
The rise of DeepSeek has further strengthened the presence of Chinese companies in the AI industry. This development raises questions about how effective U.S. government restrictions on technology exports to China will be. On the same day, former President Donald Trump announced his intention to impose tariffs on semiconductor chips imported from abroad, adding a new layer of complexity to the AI market.
The tariff policy aims to promote domestic semiconductor production in the U.S., but it also raises concerns about increased product prices, which could burden both consumers and industries.
