U.S. stocks declined sharply in a broad technology rout triggered by concerns over China's DeepSeek AI model. The Nasdaq composite led the selloff, with AI infrastructure stocks suffering steep losses, including a 16% plunge for Nvidia.
Live News
In recent trading sessions, U.S. equities moved mostly lower, with the technology-heavy Nasdaq suffering the largest declines. The selloff was sparked by reports about China's DeepSeek, an AI model that has raised questions about the competitive landscape and the pace of AI infrastructure investment.
Nvidia, a bellwether for AI chip demand, fell approximately 16% as traders exited positions across the AI ecosystem. Other makers of AI hardware and infrastructure also experienced significant losses, many declining by double-digit percentages, according to market data. The broader market, while lower, showed less severe moves, suggesting the selling was concentrated in technology and AI-related names.
The rout appears to be driven by investor reassessment of the AI spending narrative. DeepSeek's emergence suggests that smaller, more efficient AI models may reduce the need for massive computing infrastructure, potentially challenging the growth outlook for companies that supply specialized chips and data center equipment. Trading volume on the Nasdaq was elevated, reflecting heightened uncertainty.
The selloff follows a period of strong gains in AI stocks, which had benefited from robust demand forecasts. The sudden shift in sentiment highlights how quickly market perceptions can change when disruptive new technologies appear.

Expert Insights
Market analysts suggest that the rapid emergence of DeepSeek may force a recalibration of near-term growth expectations for AI-focused companies. While the selloff appears severe, some observers caution against overinterpreting a single event, noting that AI adoption remains in its early stages and that demand for computing power could still expand in other areas.
Portfolio managers point out that the selloff could create entry points for long-term investors if fundamentals remain intact, but near-term volatility is likely as the market digests the implications. The potential for more efficient AI models does not necessarily eliminate demand for infrastructure; rather, it may shift the type of hardware and software needed.
Analysts also highlight that regulatory responses and competitive dynamics between U.S. and Chinese AI firms may add further uncertainty. No specific price targets or earnings forecasts are available at this time, and investors are encouraged to rely on their own research and risk tolerance. The situation remains fluid, and further declines or recoveries are possible as more details about DeepSeek's capabilities and adoption emerge.
