A young Chinese AI startup DeepSeek sparked a massive rout in U.S. technology stocks on Monday as its highly competitive — and potentially shockingly cost-effective — models stoked doubts about the hundreds of billions that America’s biggest companies are spending on artificial intelligence.
DeepSeek’s emergence is shaking up investor confidence in the AI story that has been lifting the U.S. bull market the past two years. It calls into question the hype around Nvidia’s chips and rippled all the way through the market to hit shares of power producers who were set to get a boost from AI data center demand.
Here’s how the DeepSeek-triggered market sell-off on Wall Street unfolded:
New Reasoning Model
DeepSeek was founded in May 2023 by Liang Wenfeng, who partly funded the company by his AI-powered hedge fund. In late December, the AI developer launched a free, open-source large language model that it says took only two months to develop and less than $6 million to build.
On Jan. 20, the Hangzhou, China-based DeepSeek released R1, a reasoning model that outperformed Open AI’s latest o1 in many third-party tests.
DeepSeek is seeking to differentiate from its competitors with its reasoning capabilities, meaning that before delivering the final answer, the model first generates a “chain of thought” to enhance the accuracy of its responses.
Top-performing Model
The buzz around DeepSeek’s R1 seemingly picked up steam after Alexandr Wang, CEO of ScaleAI, touted its competitiveness against the best products from the U.S. megacap tech giants, which most had thought were leading the AI war.
“What we found is that deep seek, which is the leading Chinese AI Lab, their model, is actually the top performing, or roughly on par with the best American models,” Wang, whose company provides data to help companies train their AI tools, said on CNBC from the World Economic Forum in Davos, Switzerland last week.
Wang noted that DeepSeek actually has more H100 chips from Nvidia than expected — about 50,000 of them. Those chips are the processor of choice for AI firms in the U.S. such as OpenAI and the U.S. has banned the sale of advanced AI chips to China.
Nvidia shares took a 3% hit on Friday as chatter about DeepSeek started to pick up.
No.1 App
But it wasn’t until the past weekend when the hype surrounding DeepSeek reached a fever pitch on social media.
Marc Andreessen, co-founder and general partner of venture capital firm Andreessen Horowitz, sang DeepSeek’s praises on X, saying the R1 model is “one of the most amazing and impressive breakthroughs” he’s ever seen. Andreessen’s portfolio includes Airbnb and dozens of AI companies.
Tech investor Chamath Palihapitiya on X pointed to DeepSeek’s “very good” report, which said its R1 model “essentially cracked one of the holy grails of AI: getting models to reason step-by-step without relying on massive supervised datasets.”

By this point, DeepSeek’s mobile app surged to the top of Apple’s appstore download charts over the weekend in the U.S., marking a tangible threat to pricier models such as OpenAI’s ChatGPT.
U.S. futures were down big overnight Sunday and investors woke up to a sea of red Monday morning.

BEIJING — China missed several key targets from its 10-year plan to become self-sufficient in technology, while fostering unhealthy industrial competition which worsened global trade tensions, the European Chamber of Commerce in China said in a report this week.
When Beijing released its “Made in China 2025” plan in 2015, it was met with significant international criticism for promoting Chinese business at the expense of their foreign counterparts. The country subsequently downplayed the initiative, but has doubled-down on domestic tech development given U.S. restrictionsin the last several years.
Since releasing the plan,China has exceeded its targets on achieving domestic dominance in autos, but the country has not yet reached its targets in aerospace, high-end robots and the growth rate of manufacturing value-added, the business chamber said, citing its research and discussions with members. Out of ten strategic sectors identified in the report, China only attained technological dominance in shipbuilding, high-speed rail and electric cars.
China’s targets are generally seen as a direction rather than an actual figure to be achieved by a specific date. The Made In China 2025 plan outlines the first ten years of what the country called a ‘multi-decade strategy’ to become a global manufacturing powerhouse.
The chamber pointed out that China’s self-developed airplane, the C919, still relies heavily on U.S. and European parts and though industrial automation levels have “increased substantially,” it is primarily due to foreign technology. In addition, the growth rate of manufacturing value add reached 6.1% in 2024, falling from the 7% rate in 2015 and just over halfway toward reaching the target of 11%.
“Everyone should consider themselves lucky that China missed its manufacturing growth target,” Jens Eskelund, president of the European Union Chamber of Commerce in China, told reporters Tuesday, since the reverse would have exacerbated pressure on global competitors. “They didn’t fulfill their own target, but I actually think they did astoundingly well.”
Even at that slower pace, China has transformed itself over the last decade to drive 29% of global manufacturing value add — almost the same as the U.S. and Europe combined, Eskelund said. “Before 2015, in many, many categoriesChina was not a direct competitor of Europe and the United States.”
The U.S. in recent years has sought to restrict China’s access to high-end tech, and encourage advanced manufacturing companies to build factories in America.
The U.S. restrictions have “pushed us to make things that previously we would not have thought we had to buy,” said Lionel M. Ni, founding president of the Guangzhou campus of the Hong Kong University of Science and Technology. That’s according to a CNBC translation of his Mandarin-language remarks to reporters on Wednesday.
Ni said the products requiring home-grown development efforts included chips and equipment, and if substitutes for restricted items weren’t immediately available, the university would buy the second-best version available.
In addition to thematic plans, China issues national development priorities every five years. The current 14th five-year plan emphasizes support for the digital economy and wraps up in December. The subsequent 15th five-year plan is scheduled to be released next year.
China catching up
It remains unclear to what extent China can become completely self-sufficient in key technological systems in the near term. But local companies have made rapid strides.
“Western chip export controls have had some success in that they briefly set back China’s developmental efforts in semiconductors, albeit at some cost to the United States and allied firms,” analysts at the Washington, D.C.,-based think tank Center for Strategic and International Studies, said in a report this week. However, they noted that China has only doubled down, “potentially destabilizing the U.S. semiconductor ecosystem.”
For example, the thinktank pointed out, Huawei’s current generation smartphone, the Pura 70 series, incorporates 33 China-sourced components and only 5 sourced from outside of China.
Huawei reported a 22% surge in revenue in 2024 — the fastest growth since 2016 — buoyed by a recovery in its consumer products business.The company spent 20.8% of its revenue on research and development last year, well above its annual goal of more than 10%.
Overall, China manufacturers reached the nationwide 1.68% target for spending on research and development as a percentage of operating revenue, the EU Chamber report said.
“‘Europe needs to take a hard look at itself,” Eskelund said, referring to Huawei’s high R&D spend. “Are European companies doing what is needed to remain at the cutting edge of technology?”
However, high spending doesn’t necessarily mean efficiency.
The electric car race in particular has prompted a price war, with most automakers running losses in their attempt to undercut competitors. The phenomenon is often called “neijuan” or “involution” in China.
“We also need to realize [China’s] success has not come without problems,” Eskelund said. “We are seeing across a great many industries it has not translated into healthy business.”
He added that the attempt to fulfill “Made in China 2025” targets contributed to involution, and pointed out that China’s efforts to move up the manufacturing value chain from Christmas ornaments to high-end equipment have also increased global worries about security risks.

Such fierce competition compounds the impact of already slowing economic growth. Out of 2,825 mainland China-listed companies, 20% reported a loss for the first time in 2024, according to a CNBC analysis of Wind Information data as of Thursday. Including companies that reported yet another year of losses, the share of companies that lost money last year rose to nearly 48%, the analysis showed.
China in March emphasized that boosting consumption is its priority for the year, after previously focusing on manufacturing. Retail sales growth have lagged behind industrial production on a year-to-date basis since the beginning of 2024, according to official data accessed via Wind Information.
Policymakers are also looking for ways to ensure “a better match between manufacturing output and what the domestic market can absorb,” Eskelund said, adding that efforts to boost consumption don’t matter much if manufacturing output grows even faster.
But when asked about policies that could address manufacturing overcapacity, he said, “We are also eagerly waiting in anticipation.”
