Stock market crash fears intensified after a sharp artificial intelligence-led selloff pushed Wall Street through one of its worst sessions in more than a year, although a partial rebound on Friday and gains across parts of Asia reduced pressure on Monday.
The immediate shock came on Thursday, November 5, when investors sold technology and chip stocks amid concerns that new political pressure could slow the construction of AI data centres and weaken the spending boom that has driven much of the market’s gains.
The S&P 500 fell 4.36 per cent to close at 7,353.73, while the Nasdaq Composite dropped about 5.5 per cent and entered correction territory after falling roughly 10 per cent from its recent high.

Why the stock market crash fears spread
The selloff was concentrated initially in companies most closely linked to AI infrastructure, including semiconductor manufacturers, data-centre suppliers and large technology firms.
Nvidia shares dropped 9.3 per cent on Thursday, while technology-focused exchange-traded funds and semiconductor stocks suffered even larger losses as investors reassessed whether the pace of AI investment could continue at its previous speed.
The political backdrop added to the uncertainty after Democrats won sweeping victories in the November 3 U.S. midterm elections.
Several Democratic candidates campaigned on tighter oversight of AI development or restrictions on data-centre expansion, raising concerns that new rules, permitting limits or local moratoriums could delay projects and reduce expected demand for chips, power and construction equipment.
That concern does not mean the AI industry has stopped investing, but it has changed the market’s risk calculation after years in which large spending announcements were often rewarded by investors.
Thursday’s decline looked severe but was not a full market shutdown
The selloff spread beyond technology, with all major U.S. market sectors facing pressure during the session.
The Dow Jones Industrial Average fell about 3.4 per cent, while the broader decline suggested investors were reducing exposure across portfolios rather than simply rotating from one technology company into another.
Even so, market data indicated that the damage was heavier among growth stocks than across the average listed company.
Nasdaq Dorsey Wright reported that the S&P 500 Equal Weight Index fell 2.89 per cent on Thursday, less than the capitalization-weighted S&P 500, while the Nasdaq-100 declined 6.5 per cent.
That difference matters because the largest technology companies carry substantial weight in the headline indexes.
A sharp decline in a small group of very large companies can therefore make the overall market appear weaker than the typical stock, although it can still affect millions of retirement accounts and exchange-traded funds.
Markets recovered, but volatility remains elevated
U.S. stocks recovered on Friday, November 6, as investors bought some of the companies hit hardest during the previous session.
Asian markets also moved higher on Monday, November 9, after AI shares regained some ground in the United States, although trading remained sensitive to political developments, interest rates and the outlook for technology spending.
The rebound reduced the immediate risk of a straight-line collapse, but it did not erase the losses from Thursday.
Nasdaq Dorsey Wright said the S&P 500 finished the week down 2.68 per cent, while the Nasdaq-100 lost more than 4.9 per cent and entered correction territory.
The Cboe Volatility Index, commonly known as the VIX, closed at 25.64 on Friday after reaching substantially higher levels during the week.
The VIX measures expected 30-day volatility implied by S&P 500 options, so its elevated reading indicates that investors continue to expect larger-than-normal price movements. Cboe’s VIX term structure data provides further context for that reading.
What Canadian investors should watch next
For Canadian investors, the most important question is whether the decline remains a concentrated correction in U.S. technology stocks or develops into a broader risk-off event.
The next signals are likely to come from corporate spending plans, inflation and interest-rate expectations, government policy on data centres, and the performance of financial, industrial and consumer companies outside the AI trade.
Investors should also remember that a market correction and a stock market crash are not identical events.
A correction generally describes a decline of at least 10 per cent from a recent high, while the word crash is usually reserved for a faster and more disorderly collapse across a broad market.
The Nasdaq’s move into correction territory is therefore significant, but it does not by itself confirm that the entire U.S. market is in a crash.
For households with long-term goals, the latest volatility also underscores the importance of matching investment risk to time horizon rather than reacting to one turbulent week.
Investor.gov advises using asset allocation and diversification to spread exposure across stocks, bonds, cash and different sectors, while noting that the appropriate mix depends on an investor’s financial goals and tolerance for losses.
What happens next
Investors will be watching whether technology shares can hold their Friday recovery when regular U.S. trading resumes and whether selling spreads into less expensive parts of the market.
Fresh economic data, company earnings and announcements about AI infrastructure spending could all influence whether the recent losses deepen or stabilize.
For now, the evidence points to a severe and highly concentrated technology selloff followed by a partial rebound, rather than proof that a broad financial crisis has already begun.
That distinction could change quickly if credit markets weaken, market breadth deteriorates or major indexes continue falling despite the recovery in leading AI shares.
Frequently Asked Questions
Was there a stock market crash in November 2026?
Markets experienced a severe AI-led selloff on November 5, but the available evidence described a sharp correction and partial rebound rather than a confirmed broad-market crash.
Why did AI stocks fall so sharply?
Investors worried that political pressure and possible regulation could slow AI data-centre construction and reduce the pace of spending on chips, power and related infrastructure.
Which indexes were hit hardest?
The Nasdaq Composite and Nasdaq-100 were hit harder than the broader S&P 500 because they have greater exposure to large technology and growth companies.
What does a VIX reading above 25 mean?
The VIX reflects expected 30-day S&P 500 volatility, and a reading above 25 generally signals that investors expect larger-than-normal market moves.
What should Canadian investors do during market volatility?
Investors should review their time horizon, risk tolerance and diversification rather than make rushed decisions based only on a single market session.
