NextFin news, on November 21, 2025, both US and major Asian stock markets saw significant declines amid persistent investor jitters surrounding artificial intelligence (AI) investments. The sell-off was led by high-profile technology firms with strong AI exposure, including US chipmaker Nvidia and Asian semiconductor leaders Samsung Electronics and SK Hynix. The downturn unfolded broadly across regions: the US Nasdaq experienced volatility influenced by weaker-than-expected employment data casting doubt on further interest rate cuts by the Federal Reserve, while Asia's Kospi index in South Korea dropped nearly 4%, Tokyo’s Nikkei fell by 2.3%, and Taiwan’s Taiex declined by 3.1% in intra-day trading.
These movements occurred in the context of a mixed market atmosphere following Nvidia’s recent earnings that surpassed expectations with robust demand for AI chips powering generative AI systems. Nvidia’s valuation briefly peaked above $5 trillion USD last month but has since retreated to approximately $4.4 trillion. Notably, SoftBank, a major investor in AI firms including ChatGPT maker OpenAI, declined more than 10%, reflecting concerns over the sustainability of multi-billion dollar AI infrastructure projects like the $500 billion US Stargate initiative.
Investor anxiety stems from the intersection of stretched AI valuations and broader macroeconomic uncertainties. The US jobs report introduced doubts about additional Federal Reserve rate cuts, which traditionally support tech sector growth. Simultaneously, geopolitical tensions and escalating costs associated with building massive energy-intensive AI data centers add to market unease. Analysts from Kiwoom Securities observed that South Korea’s tech market remains tethered to jitters in US technology shares, with daily swings in Nasdaq futures and Nvidia’s after-hours trading significantly shaping regional investor sentiment.
Stephen Innes of SPI Asset Management characterized the selloff as a psychological ‘‘air pocket’’, a sudden and hard-to-explain reversal that veteran traders recognize but find difficult to quantify in real-time. The rapid fading of optimism earlier in the US trading day exemplified this volatility, as momentum dissipated sharply before US lunch hours. This episode highlights the fragile nature of the current AI investment environment, where strong fundamentals can be overshadowed by risk aversion and valuation skepticism.
The underlying backdrop of this market turbulence includes projections from technology research firm Gartner, which estimates worldwide AI-related spending to reach nearly $1.5 trillion in 2025 and surpass $2 trillion by 2026. Such expenditure represents close to 2% of global GDP, illuminating the scale and economic significance of AI ventures. However, the pace of investment inflows and sky-high valuations raise concerns about overheating in AI equities, likened by some investors to a speculative bubble.
This selloff in technology-heavy markets reflects both localized issues—such as supply chain pressures in Asian semiconductor manufacturing—and global macro trends, including the Federal Reserve's monetary stance under the administration of US President Donald Trump. His administration's policies, particularly on technology, infrastructure, and energy investments, also contribute to the market's complex risk calculus.
Looking forward, market participants will be closely monitoring upcoming US economic data, Federal Reserve policy signals, and quarterly earnings reports from key AI sector players. The evolving geopolitical landscape, especially tensions affecting semiconductor supply chains and tech infrastructure development, will continue to influence regional and global stock market performance.
Investors need to balance awareness of AI’s transformative potential and substantial capital allocation against the probable volatility and risk associated with rapidly escalating valuations. The current pullback may serve as a recalibration period where markets digest AI’s long-term economic impact amid ongoing inflationary and interest rate uncertainties.
In conclusion, the November 2025 selloff in US and Asia stock markets amid AI investment jitters elucidates the intersection of technological innovation, market psychology, and macroeconomic policy. While AI remains a critical engine for future growth, investors and policymakers alike must navigate a challenging landscape marked by valuation discipline, geopolitical friction, and shifting economic conditions.
According to Business Today Malaysia, the Asian technology sector's sensitivity to US market movements and the recent Nvidia earnings report underscores the cross-regional interconnectedness and short-term volatility rooted in the AI narrative. Bloomberg reports further highlight the downtrend in major Asian tech stocks, emphasizing the vulnerability of chipmakers to global economic shifts. Together, these insights illustrate the nuanced and dynamic environment shaping AI investment trends and stock market behavior in late 2025.
