Why did the stock market crash today is the question every investor is asking after Thursday’s rout, which erased the post election rally in a single session. The Nasdaq Composite fell 5.52 percent to 24,315, its worst day since April 2025, and closed in correction territory, more than 10 percent below its October 6 record. The S&P 500 dropped 4.36 percent to 7,353.73 and the Dow Jones Industrial Average lost 1,833 points, or 3.44 percent, to 51,523. The Philadelphia Semiconductor Index fell more than 12 percent, and Nvidia lost over 9 percent. The VIX fear gauge jumped about 70 percent to 28.18. Traders blamed the midterm results, which they think could slow the construction of AI data centers. We’ll be updating this article monthly as markets settle and new data arrives.
The label “crash” deserves care. Thursday was the worst day in more than a year, but it was not close to the worst in history, a point that matters because President Trump wrote on Truth Social that the market “suffered one of the Worst Days in History based on the results of the Election.” Analysts told reporters the picture is messier. Futures were mixed early Friday, with the Nasdaq 100 up about 1.4 percent and the Dow down about 0.8 percent, while Asian markets sold off hard. The October jobs report arrives this morning, and investors are watching whether it changes Federal Reserve rate hike expectations. Below is a plain explanation of what happened, who lost the most, what is scheduled next and a calculator to see what a drop means for your own money.

Why Did the Stock Market Fall Today?
No single event explains a drop this big. Reporting points to five overlapping causes.
1. Fear that Democrats will slow the AI data center buildout
This is the headline explanation. CBS News reported that investors worried a shift in congressional control could strengthen opponents of data centers, which have sparked widespread public opposition, and slow their rollout. Rising electricity prices turned data center construction into a political issue, according to Fox Business, and some Democrats have called for pauses or limits on new projects.
Nocta’s daily brief, a smaller newsletter, added that Texas governor-elect Gina Hinojosa pledged to halt new data center approvals, and that an NBC exit poll found 76 percent of voters oppose new data center construction in their communities. OpenAI responded with a plan for public reporting of water and electricity use, the same brief said. Adam Crisafulli of Vital Knowledge described the move as investors reacting to growing “headline” risks around artificial intelligence.
eToro analyst Jakub Rochlitz put it simply: “markets are pricing in the midterm results.” He said the market’s reading is that the AI buildout becomes slower and more expensive.
2. A rally that reversed
Wednesday brought a relief rally after the election, which analysts said reflected the political risk premium unwinding. On Thursday, traders reconsidered what a Democratic House and Senate could mean for technology. Nvidia had already fallen 3.2 percent on Wednesday, CBS reported, before dropping more than 9 percent on Thursday.
3. Doubts about AI spending
Fox Business reported that investors were also worried about the heavy borrowing and spending behind the AI boom, rising energy costs and uncertain future returns. The election gave those worries a trigger. Argent Capital’s Jed Ellerbroek said the selling “feels like the capitulation phase” for data center beneficiaries, particularly semiconductors, though he thought the size of the moves was outsized.
4. Interest rate worries
Rate expectations are part of the background. According to Nocta, CME FedWatch showed about a 70 percent chance of a 25 basis point Fed hike at the December meeting, and NordFX put it at 67 percent. The Bank of England voted 8 to 1 on Thursday to raise rates 25 basis points to 4 percent, its first increase in more than three years, Nocta said. Higher rates make expensive growth stocks less attractive, which hurts technology most.
5. Company news and oil
Qualcomm fell after a weak smartphone chip forecast, its steepest one day drop since 2020, according to Nocta. Oil added to the uneasy mood. CBS reported Brent crude rose 2.6 percent to $97.11 on Thursday, recovering much of the nearly 9 percent drop from the day before, and the article said uncertainty remains about the war with Iran. Nocta said fresh tanker attacks in the Gulf renewed supply worries.
Which Stocks Fell the Most?
| Stock or group | Thursday move |
|---|---|
| Philadelphia Semiconductor Index | Down more than 12 percent |
| Nvidia | Down about 9.3 percent to $181.60, losing over $440 billion in value |
| AMD | Down about 14.6 percent (CBS, midday); 17 percent at the close (Nocta) |
| Micron | Down about 17 percent (Nocta) |
| SanDisk | Down more than 22 percent (Nocta) |
| Tesla | Down about 10.8 percent to $343.69 |
| CoreWeave | Down about 12.1 percent (CBS, midday) |
| IREN, Applied Digital, Nebius | Each down more than 14 percent |
| Datadog | Down 14.4 percent |
| Lam Research | Down 10.4 percent |
| Meta | Down about 4 percent |
| Alphabet and Amazon | Each down about 2.2 percent |
The Magnificent Seven group of mega cap stocks lost more than $1 trillion combined, Nocta reported. A CNN headline put the broader technology loss at $2.5 trillion, though CNN’s page could not be opened for this article, so treat that figure as unconfirmed.
Who gained
Not everything fell. According to Nocta and a related market report, AppLovin rose about 11 percent on earnings, CDW rose 12.7 percent, Booking Holdings gained 9.8 percent, 3M rose 9.6 percent, and Home Depot and Lowe’s gained 6.5 percent and 7.5 percent. The pattern suggests investors rotated away from AI infrastructure and toward companies that look less exposed.
Is It a Stock Market Crash? What the Terms Mean
There is no official definition of a crash. The terms analysts use are more specific.
| Term | Usual meaning | Where things stand |
|---|---|---|
| Correction | A drop of 10 percent or more from a recent high | The Nasdaq is in one |
| Bear market | A drop of 20 percent or more from a high | Not reached by US indexes in these reports |
| Crash | A very sharp one or two day fall, with no fixed number | Disputed; the S&P fell 4.36 percent |
| Circuit breaker | A trading halt after a big fall | Triggered at the open in South Korea, according to NordFX |
By percentage, Thursday ranks well below the worst days on record, such as Black Monday in 1987 or the pandemic sell-off in March 2020, when the S&P 500 fell far more in a day. That comparison comes from general market history, not the sources reviewed, so check it against a market data provider.
Trump Blames Democrats: What the Claim Gets Right and Wrong
Trump posted that the sell-off came “based on the results of the Election” and added: “Your 401(k)s have, therefore, dropped.” He also wrote: “Remember, it wasn’t Republicans, it was Dumocrats.” Fox Business did not include a White House statement beyond his posts or a Democratic response.
The election did play a role, since analysts including Rochlitz said markets were pricing in the midterm results. But that is not the same as the whole story. Rate hike odds, doubts about AI spending, a weak chip forecast and oil all contributed. And the claim that this was one of the worst days in history is not supported by the numbers. It was the worst day since April 2025, which is notable but not historic.
What About Asian and Global Markets?
Wall Street’s sell-off spread overseas on Friday.
| Market | Move reported |
|---|---|
| Japan Nikkei 225 | Down about 6 percent, into bear market territory per TipRanks |
| South Korea Kospi | Down about 6 percent, with a circuit breaker at the open |
| Taiwan Weighted | Down about 4.5 percent |
| Hang Seng | Down about 1.1 percent |
| Shanghai Composite | Down about 1.1 percent |
| ASX 200 | Down about 0.5 percent |
Sources disagree slightly on exact percentages because the markets were moving while the reports were written. Fox Business noted that Japan’s Nikkei and Korea’s Kospi, both up more than 20 percent this year, were hit hard because of their exposure to chips and AI.
What Happens Today? The Jobs Report and the Market Open
Futures suggested a mixed open. TipRanks showed Nasdaq 100 futures up 1.35 percent, S&P 500 futures up 0.27 percent and Dow futures down 0.82 percent at 5:35 a.m. Eastern. Micron, SanDisk and SK Hynix were reported to be surging in premarket trading after Thursday’s drop.
The key event is the October nonfarm payrolls report. The Dow Jones consensus is about 59,000 jobs added, while NordFX cited a forecast of 65,000 against 29,000 the month before, with unemployment expected to hold at 4.2 percent. A weak number could ease rate hike worries but raise concern about growth. A strong number could lift hike odds. University of Michigan consumer sentiment also comes out, and earnings from Moderna, Humana and Charter Communications are on the calendar.

Illustrative math only. Real funds differ from the indexes, so your actual change may be smaller or larger. This is not investment advice. Check your account for exact figures and speak with a registered adviser about your plan.
What a Drop Like This Means for Your 401(k)
A sell-off feels bigger when you see it in dollars. Here is what Thursday’s moves mean on $100,000 invested fully in each index, assuming your fund tracks it exactly.
| If you hold | One day loss | Gain needed to get back to even |
|---|---|---|
| Dow index fund | $3,440 | 3.56 percent |
| S&P 500 index fund | $4,360 | 4.56 percent |
| Nasdaq index fund | $5,520 | 5.84 percent |
The recovery math is not symmetric. A 10 percent loss requires an 11.1 percent gain to break even, and a 20 percent loss requires 25 percent. The calculator below handles your own numbers.
Most 401(k) accounts hold diversified funds, so your actual drop was probably smaller than the Nasdaq’s. A target date fund or a bond heavy mix would have fallen less. This is general information, not financial advice. If you are close to retirement or worried about your allocation, a registered adviser or your plan’s help line can look at your specific situation.
How to Check Your Portfolio and Official Market Data
You do not need to apply for anything, but these steps give you reliable information.
- Log in to your brokerage or 401(k) account and check the actual change in your holdings.
- Look at the percentage, not just the dollars, since account size changes the dollar figure.
- Use official data for the jobs report on the Bureau of Labor Statistics site.
- Check exchange websites for index levels and trading halts.
- Avoid acting on social media tips or unsolicited calls about “crash” opportunities.
How Long Do Sell-Offs Take to Recover?
Nobody can say. Some drops reverse within days and others lead to months of losses. What can be said is what to watch. Traders will look at whether the jobs report changes Fed expectations, whether chip stocks stabilize after Friday’s Asian trading, whether oil prices keep rising and whether Democrats signal policy on data centers and AI when the new Congress begins on January 3.
Why Tech Stocks Move Whole Indexes
A handful of very large technology companies now carry a big share of the S&P 500 and almost all of the Nasdaq’s weight, which is why a sell-off in AI names can drag down an entire index even when many other stocks barely move. Thursday showed it clearly. Nvidia alone lost more than $440 billion in value and the Magnificent Seven lost more than $1 trillion together, while companies such as Home Depot and Lowe’s rose. If your fund is heavily weighted toward large technology stocks, expect it to swing more than a broad, equal weighted fund.

FAQs
Why did the stock market crash today?
Stocks fell sharply on Thursday, November 5, mainly because investors feared that Democratic wins in the midterms could slow AI data center construction. Rate hike worries, doubts about AI spending and oil also played a part.
How much did the Nasdaq fall?
It fell 5.52 percent to 24,315, its worst day since April 2025.
How many points did the Dow lose?
The Dow fell 1,833 points, or 3.44 percent, to 51,523.
Is the stock market in a correction?
The Nasdaq is, because it closed more than 10 percent below its October 6 record. The S&P 500 and Dow were not reported to be at that level.
Did the election cause the stock market drop?
It was a trigger according to analysts such as eToro’s Jakub Rochlitz, but not the only cause.
Will the stock market recover?
No one can say. Futures were mixed early Friday, and the jobs report is a key test.
What is the VIX?
It is a measure of expected market volatility. It rose about 70 percent to 28.18, its highest since March 31.
Was it the worst day in stock market history?
No. It was the worst day since April 2025 for the Nasdaq and the S&P 500, but earlier crashes were far larger.
Why did Nvidia stock drop?
Nvidia fell more than 9 percent as investors worried that slower data center building could cut demand for AI chips. It had already fallen 3.2 percent the day before.
Why are chip stocks falling?
The Philadelphia Semiconductor Index fell more than 12 percent because chipmakers depend on the data center buildout, and traders fear it will slow and cost more.
Should I sell my stocks after a crash?
This is a personal decision that depends on your goals and timeline. A registered financial adviser can help, and selling after a drop locks in the loss.
Will the Fed raise interest rates in December?
Markets price a 67 to 70 percent chance of a quarter point hike, according to CME FedWatch figures cited by NordFX and Nocta. Nothing is decided.
What happened to bitcoin?
Bitcoin fell about 5.7 percent to roughly $75,900, with over $1 billion in leveraged positions liquidated, according to Nocta and NordFX.
Conclusion
Thursday’s sell-off was real and large. The Nasdaq entered a correction, the S&P 500 had its worst day in more than a year and chip and AI stocks took the heaviest hit, with the midterm results serving as the trigger for investors who were already nervous about AI spending, rates and oil. The claim that it was one of the worst days in history is not supported by the numbers, and the claim that the election alone caused it is incomplete. Today’s jobs report and Asian trading will shape the next move. If you are worried about your accounts, look at your actual holdings, avoid rushed decisions and rely on official data. We’ll be updating this guide as the market and policy picture changes.
