Wall Street was shocked by the latest technological breakthrough from the Chinese AI startup DeepSeek. DeepSeek’s revelation of methods to produce large language models that can self-improve at low costs without human intervention became a turning point, questioning the U.S.’s leadership in the AI field.

Global stock markets experienced significant declines from New York to London and Tokyo. This drop was particularly notable as it came shortly after a rally. On Monday, the Nasdaq 100 fell by 3%, and the S&P 500 by 1.5%. The companies leading this decline were mostly technology firms, with chip and other hardware manufacturers losing considerable value due to the success of the Chinese company. The Semiconductor Index experienced its largest drop since March 2020. Nvidia, known as the architect of America’s AI triumph, saw an unprecedented single-day market value loss of 17%, which translated to a vaporization of more than half a trillion dollars from its market cap. The stocks of Alphabet, Amazon, and Microsoft also dropped by 3%, 1%, and 3% respectively, leading to a total loss of approximately $1 trillion for American tech companies.

DeepSeek, with its latest major AI language model R1, stands as the primary reason behind this shock wave, or according to some, the bursting of a bubble in these markets. DeepSeek’s chatbot became the most downloaded app on iPhones over the weekend. This model can provide performance equivalent to its Western counterparts with significantly less computational power and cost. The real market shock came with a wake-up call regarding whether trillion-dollar investments in AI were necessary, as a small Chinese company could achieve the performance of American tech giants at much lower costs. American tech giants appear to have invested heavily in data centers and AI infrastructure, with last year’s expenditures increasing by 57% to nearly $180 billion. DeepSeek’s efficiency model suggests that some of these investments might be unnecessary, raising market concerns for data center suppliers and energy companies. In Western countries, DeepSeek’s success has created a “Sputnik Moment”. There are clear parallels with the space race during the Cold War between the U.S. and the Soviet Union. While the U.S. has imposed embargoes and sanctions on China, particularly in tech infrastructure and chips, this unexpected success from China will undoubtedly have global repercussions. As the U.S. reevaluates its strategies, China has secured a significant advantage in the technology of the future. In the markets, investments related to AI will now transition to a completely different level in terms of supply and demand, suggesting that the shockwaves from this event could have a long-lasting impact.
