A sharp AI stock sell-off wiped roughly $2.3 to $2.5 trillion off technology shares worldwide on November 5-6, 2026, as the Nasdaq 100 fell about 6% and chip stocks led the drop. Investors grew worried that AI spending had outrun near-term returns, and that new political scrutiny of data centers after the U.S. midterm elections could slow the AI buildout. The rout spread from Wall Street to Asian markets and even to Bitcoin within hours.

What Happened to AI Stocks on November 5, 2026?
U.S. technology stocks suffered their steepest single-day decline in nearly two years on November 5, 2026. The Nasdaq 100, which tracks the 100 largest non-financial companies on the Nasdaq exchange and is heavily weighted toward AI-related firms, fell about 6%. Reuters described it as the index’s biggest daily drop in 19 months, and MarketWatch called it tech stocks’ worst day since 2020.
The decline was not limited to one sector. Chipmakers, cloud providers, and AI infrastructure companies all fell together, which is typical when investors reassess an entire investment theme rather than one company’s results. The Philadelphia Semiconductor Index (SOX), a benchmark of major U.S. chip stocks, plunged roughly 12% as the sell-off deepened into its second day, Bloomberg reported.
How Much Money Did the Sell-Off Wipe Out?
Bloomberg reported that the Nasdaq 100’s drop erased a record $2.3 trillion in market value in a single session. The Wall Street Journal framed the broader damage across technology stocks at $2.5 trillion, describing it as a “reality check” for the AI trade, the market shorthand for the cluster of stocks tied to AI chips, cloud computing, and data centers. Both figures describe the same underlying event from slightly different angles: one measuring the Nasdaq 100 specifically, the other measuring the wider tech-stock rout.
| Metric | Reported figure | Source |
|---|---|---|
| Nasdaq 100 one-day change | About -6% | Bloomberg, Reuters |
| Nasdaq 100 value lost | Record $2.3 trillion | Bloomberg |
| Broader tech-stock loss | $2.5 trillion | Wall Street Journal |
| Philadelphia Semiconductor Index | About -12% | Bloomberg |
| Nvidia share price | About -9% | Livemint |
| South Korea’s Kospi | -8.7% | Nikkei Asia |
| Japan’s Nikkei | -6.7% | Nikkei Asia |
| Bitcoin price | Fell to about $76,000 | CoinDesk |
Why Are Investors Worried About the AI Trade?
The “AI trade” is shorthand for the group of stocks, mostly chipmakers, cloud providers, and data center builders, that rose sharply as companies raced to build AI infrastructure over the past few years. By late 2026, several of these companies were trading at valuations that assumed years of uninterrupted AI spending growth.
Reuters described the November 5 move as an acceleration of a broader “retreat from the AI trade” rather than a single-day panic. The BBC reported that the sell-off followed the U.S. midterm elections, with investors concerned that election results could slow AI data center approvals through tighter local and federal oversight. Gizmodo reported that AI investors were anticipating heavier scrutiny from Democratic lawmakers following the vote. CNBC’s Jim Cramer offered a more measured view, saying the AI sell-off was not over but was not a repeat of the dot-com crash of the early 2000s, since today’s leading AI companies generate substantial real revenue and profit, unlike many dot-com-era firms.
How Did Asian Markets and Chip Stocks React?
The sell-off crossed time zones quickly. CNBC reported that South Korea’s SK Hynix and Samsung, Japan’s SoftBank, and Taiwan’s TSMC, all major suppliers in the AI chip supply chain, tumbled in Asian trading hours after the U.S. close. Nikkei Asia reported that Taiwan’s Taiex index recorded its steepest-ever intraday point drop, South Korea’s Kospi fell 8.7%, and Japan’s Nikkei dropped 6.7%, with South Korean exchanges briefly halting trading amid the volatility.
The reaction was not confined to equities. CoinDesk reported that Bitcoin fell to around $76,000 as the broader AI-linked sell-off dragged down risk assets generally, though it noted that at least one trader saw reasons for cautious optimism once the immediate panic passed.
Is This a Repeat of the Dot-Com Crash?
Not according to most of the analysts covering the sell-off. The dot-com crash of 2000-2002 involved many internet companies with little or no revenue. By contrast, the major AI companies at the center of the November 2026 sell-off, including chipmakers and cloud providers, report tens of billions of dollars in actual revenue tied to AI products and services. CNBC’s Jim Cramer made this distinction explicitly, arguing the current sell-off reflects a reassessment of how fast AI spending can keep growing, not a collapse of the underlying business.
That said, Fortune reported that some investors now see a premature end to the AI data center boom as a real possibility if financing and regulatory conditions tighten at the same time. The Boston Globe linked the sell-off directly to expectations that Democratic gains in the midterms could slow AI-related infrastructure approvals.
What Does This Mean for AI Companies and Investors?
A sharp stock sell-off does not, by itself, change what AI companies are building or how their technology works. It mainly affects how investors value future AI spending and growth. Chipmakers and cloud providers with large data center commitments may face more pressure to show near-term returns on AI infrastructure, and companies planning IPOs or funding rounds in AI may encounter more cautious investors in the short term, as the Wall Street Journal separately reported in connection with Anthropic’s IPO plans.
For businesses already using AI agents, chatbots, or automation tools, the sell-off does not change day-to-day functionality. It is a market event about valuation and investor sentiment, not a technical or product event.

Frequently Asked Questions
Why did AI stocks crash on November 5, 2026?
AI stocks fell sharply because investors grew concerned that AI infrastructure spending had outpaced near-term returns, and that the results of the U.S. midterm elections could bring tighter scrutiny of AI data centers, according to Reuters and the BBC.
How much money was lost in the AI stock sell-off?
Bloomberg reported a record $2.3 trillion wiped off the Nasdaq 100, while the Wall Street Journal put the broader tech-stock loss at $2.5 trillion.
Which stocks were hit hardest?
U.S. chipmakers were hit hardest, with the Philadelphia Semiconductor Index falling about 12% and Nvidia down roughly 9%, per Bloomberg and Livemint. Asian chip suppliers including SK Hynix, Samsung, SoftBank, and TSMC also fell sharply, CNBC reported.
Is this the start of an AI bubble bursting?
It is not confirmed to be one. CNBC’s Jim Cramer said the sell-off was not over but was different from the dot-com crash, since today’s leading AI companies have substantial real revenue. Fortune reported that some investors see a risk of the AI data center boom ending earlier than planned, but this remains a market concern, not a confirmed outcome.
Did the sell-off affect markets outside the United States?
Yes. Nikkei Asia reported that South Korea’s Kospi fell 8.7%, Japan’s Nikkei dropped 6.7%, and Taiwan’s Taiex recorded its steepest-ever intraday point drop as the sell-off spread to Asian markets.
