US stock markets suffered a historic selloff on Thursday, November 5, wiping approximately $3 trillion from the market value of S&P 500 companies as investors fled artificial intelligence and semiconductor stocks following the Democrats' sweeping victory in the midterm elections. The collapse abruptly reversed Wednesday's post-election rally, when major technology companies had been on track to gain more than $750 billion in combined market capitalization. The Nasdaq Composite plunged 5.52%, its worst daily decline in 19 months, while the S&P 500 dropped 4.36%, its steepest fall since the April 2025 tariff shock. The Dow Jones Industrial Average lost 1,833 points, or 3.44%. ## Wall Street's Historic Selloff NOVEMBER 5, 2026 — CLOSING PERFORMANCE ![Chart](https://storage.ghost.io/c/0a/8d/0a8df20e-472a-4937-9276-15729249f663/content/images/2026/11/data-src-image-383a0950-f4dc-4c44-8551-dc05f95efa9a.png) Source: Reuters, Bloomberg and AP. The technology-heavy Nasdaq 100 lost a record $2.3 trillion in market capitalization, while the broader Nasdaq Composite shed an estimated $2.5 trillion. The selloff pushed the Nasdaq Composite approximately 12% below its October record, placing the index firmly in correction territory. Semiconductor companies suffered particularly severe losses as the Philadelphia Semiconductor Index plunged more than 12%, one of its worst performances on record. ## Nvidia, AMD and Other AI Giants Lead the Collapse The market's biggest losers were companies closely connected to the enormous global expansion of AI data centers. SELECTED TECHNOLOGY STOCK LOSSES — NOVEMBER 5 | Company | Daily decline | | ----------------- | ------------- | | Micron Technology | −17.5% | | AMD | −17.3% | | Broadcom | −10.4% | | Nvidia | −9.3% | | GE Vernova | −7.5% | Rounded closing-price changes. Nvidia alone lost more than $400 billion in market capitalization during the session. Selling also spread beyond chipmakers to data-center developers, electricity suppliers and infrastructure companies that had benefited from the AI investment boom. The losses demonstrate how heavily US equity valuations have become dependent on expectations of sustained growth in artificial intelligence spending. ## Why Democrats' Victory Triggered the Selloff The market turmoil reflects growing expectations that a Democratic-controlled Congress will introduce greater scrutiny of AI development and the construction of massive data centers. Several newly elected Democratic lawmakers have advocated restrictions or temporary moratoriums on new data-center projects, citing concerns about electricity consumption, water resources and rising utility costs. Investors fear that tougher approval requirements could delay infrastructure construction and reduce demand for the advanced chips, servers and electricity equipment needed to power AI systems. The reaction is particularly significant because major technology companies have committed hundreds of billions of dollars to expanding their AI capabilities. A slowdown could force analysts to revise revenue expectations for semiconductor manufacturers and infrastructure providers. However, no nationwide moratorium has been enacted. The selloff reflects expectations about future policy rather than confirmed federal restrictions. ## From Election Euphoria to Market Panic The speed of the reversal was particularly striking. On Wednesday, Wall Street surged following the Democratic election victory, with the Dow recording its strongest post-midterm performance in decades. Investors initially welcomed the prospect of divided government, lower oil prices and possible constraints on Trump's economic policies. By Thursday, however, attention shifted toward the potential consequences of stricter technology regulations and the enormous financing requirements of the AI industry. The selloff also reflected concerns about whether the massive investments being made in AI will ultimately generate sufficient profits. As the market declined, selling intensified, affecting companies beyond technology and contributing to a broad retreat from riskier investments. ## The Selloff Spreads Across Asia The turmoil quickly extended beyond the United States. During Friday's Asian trading session, South Korea's Kospi plunged more than 8%, triggering a temporary trading halt, while Japan's Nikkei and Taiwan's stock market also suffered sharp declines. The losses reflect Asia's central role in producing the semiconductors and equipment used by American technology companies. A prolonged slowdown in AI infrastructure investment could therefore affect global supply chains, not just Silicon Valley. ## What Comes Next for Wall Street? The immediate outlook remains uncertain. Investors will be watching whether Democratic lawmakers pursue concrete restrictions on AI infrastructure, how major technology companies adjust spending plans and whether corporate earnings can justify elevated valuations. Federal Reserve policy, borrowing costs and the economic consequences of the Iran war will also influence market sentiment. Despite Thursday's historic losses, the S&P 500 and Nasdaq remained positive for 2026, suggesting that the selloff has not erased the market's gains for the entire year. A recovery remains possible if regulatory fears ease and technology companies continue reporting strong demand for AI services. Conversely, tighter financial conditions or weaker infrastructure investment could prolong the decline. The immediate lesson from Wall Street's $3 trillion rout is that the AI boom has become a major source of market vulnerability. Investors are no longer simply questioning how fast artificial intelligence will grow, but whether the enormous sums being spent to build it can deliver sustainable returns.
