The meteoric rise of DeepSeek, a Chinese open-source AI, has sent ripples through the US stock market, disrupting the tech sector. Developed by a Chinese AI company, DeepSeek has swiftly outpaced established rivals like ChatGPT, becoming the most downloaded free app in the United States within a week of its launch.
This unexpected surge in popularity has unnerved investors, sparking a sell-off in major AI-driven tech stocks before Monday’s market opening. Industry giants such as Nvidia, Microsoft, and Meta have experienced significant declines, marking a pivotal moment for the US tech landscape.
Wall Street’s Tech Stocks Take a Hit
DeepSeek’s rapid emergence coincided with a steep drop in US tech stocks. The Nasdaq Composite, heavily dominated by tech firms, fell nearly 3%, leading a broader market downturn. The S&P 500 slid by 1.7%, while the Dow Jones Industrial Average declined modestly by 0.2%.

Nvidia, a leading player in AI chip manufacturing, saw its shares nosedive by almost 11%, reflecting concerns over its ability to maintain a competitive edge amid growing global challenges. Other chipmakers like ASML, Broadcom, and Micron Technology also suffered substantial losses.
Microsoft, which has invested heavily in AI initiatives, experienced a 3% drop in its stock price. Meanwhile, tech heavyweights Alphabet (Google’s parent company), Meta, and Amazon faced similar declines as investor confidence in the tech sector waned.
The Impact of DeepSeek’s Disruption
DeepSeek’s swift rise has sparked fears over the dominance of US-based AI firms. Powered by the cost-effective DeepSeek-V3 model, the app claims to outperform industry leaders while utilizing fewer resources and cheaper hardware. Its reported development cost of under $6 million starkly contrasts with the billions spent by US competitors.
This affordability and efficiency have led investors to question the long-term growth prospects of US tech companies heavily invested in AI advancements. DeepSeek’s open-source strategy exemplifies China’s collective approach to AI development, heightening concerns within Silicon Valley.
DeepSeek and US-China AI Rivalry
The success of DeepSeek emerges amidst escalating trade tensions between the US and China. Restrictions imposed by the US on the sale of advanced chips to China have driven Chinese developers to innovate with collaborative and cost-efficient solutions.
DeepSeek’s rise could represent a turning point in the global AI industry, challenging the US’s historical dominance. Its sudden success has prompted a reevaluation of the competitive landscape, signaling a shift in the balance of technological power.
A Visionary Founder
DeepSeek was founded in 2023 by Liang Wenfeng, a Hangzhou-based information and electronic engineering graduate. His goal of creating an accessible yet highly capable AI model has now positioned DeepSeek as a revolutionary force in the competitive AI market.
As the implications of DeepSeek’s ascent continue to unfold, its impact on the global AI industry and the US stock market underscores the rapidly changing dynamics of innovation and competition in the tech world.
