Wall Street Selloff: Nasdaq Plunges 5.5% as AI Stocks Crash during a turbulent trading session on November 5. The S&P 500 fell 4.4%, while the Dow lost more than 1,800 points. Concerns about artificial intelligence investments and future data center projects triggered widespread selling.
Wall Street Stock Market Selloff
Wall Street suffered its steepest daily decline since April 2025 on Thursday, November 5, as investors sold technology shares and reassessed the outlook for artificial intelligence spending.
The Wall Street stock market selloff erased the previous session's gains, putting pressure on major US indexes and companies linked to semiconductor manufacturing and data center construction.
Investor concerns intensified over whether future government regulations, expensive borrowing and slowing infrastructure development could weaken demand for AI-related products.
Nasdaq and S&P 500 Decline
The Nasdaq and S&P 500 decline reflected widespread weakness across US financial markets.
The Nasdaq Composite plunged 5.5% to close at 24,315 points, entering correction territory after falling more than 10% below its October record.
The S&P 500 dropped 4.4% to 7,353.73, while the Dow Jones Industrial Average lost 1,833 points, or 3.4%, ending at 51,523.06.
All 11 S&P 500 sectors finished lower, showing that selling pressure had spread beyond technology companies.
AI Semiconductor Stocks Crash
AI semiconductor stocks crashed as investors questioned whether rapid spending on data centers could continue at its previous pace.
Nvidia shares fell approximately 9.3%, while Advanced Micro Devices plunged 17.3%. Semiconductor companies faced heavy losses as investors reconsidered growth expectations.
The Philadelphia Semiconductor Index declined about 12.2%, recording its steepest single-session fall since April 2025.
The sharp drop reflected concerns that reduced demand for computing infrastructure could affect chip manufacturers, equipment suppliers and energy companies.
US Midterm Election Market Impact
The US midterm election market impact became another concern following Democratic victories in the November 3 congressional elections.
Investors worried that changes in congressional leadership could introduce stronger oversight of artificial intelligence projects and restrictions on data center development.
However, the election was not the only factor behind the decline. High technology valuations, heavy capital spending and uncertainty over future earnings also contributed to the selloff.
The reaction highlighted growing questions about the financial sustainability of the AI investment boom.
Global Stock Market Volatility
Global stock market volatility increased as the Wall Street decline affected investor sentiment beyond the United States.
Asian technology shares came under pressure, while investors also monitored movements in government bonds, currencies and energy prices.
The selloff raised concerns about how heavily global markets depend on artificial intelligence companies for growth.
Investors will now focus on economic data, corporate earnings and future policy decisions to assess whether the latest decline represents a temporary correction or a longer period of market weakness.
