A month ago, Nvidia was the most valuable company on the planet and its stock was at a record. On Thursday it had its worst day since January 2025. Shares fell more than 9% to close at $181.60, wiping out roughly $440 billion in market value in a single session.
That raised an obvious question, and UNILAD Tech asked it: what happened to anyone who bought at the top? We checked the numbers, and then looked at why one election triggered the biggest tech selloff in years.
The short version
- $1,000 invested at Nvidia’s October 5 peak of $243.37 is now worth about $746, a 25.4% loss.
- On November 5, the Nasdaq 100 fell about 6.3% and lost roughly $2.3 trillion in value. Chip stocks dropped 12%.
- Investors are betting that a Democratic Congress will slow the AI data center buildout through hearings, regulation and local opposition.
- The selloff spread to Asia on Friday, triggering a trading halt in South Korea.
- Long-term holders are still far ahead. $1,000 bought when ChatGPT launched in 2022 is worth over $10,700.
The $1,000 math
Nvidia’s stock hit an all-time high of $243.37 on October 5, 2026, according to UNILAD Tech. At that price, $1,000 bought about 4.11 shares. At Thursday’s close of $181.60, those shares are worth $746.19. That’s a paper loss of $253.81, or about 25.4%, in one month.
Where you got in makes all the difference, though. Here’s the same $1,000 at a few other moments, all valued at the November 5 close and adjusted for Nvidia’s 10-for-1 stock split in 2024.
| If you bought $1,000 on… | Share price | Worth today | Change |
|---|---|---|---|
| Nov 30, 2022 (ChatGPT launch) | $16.92 | $10,731 | +973% |
| Oct 29, 2025 (first $5T close) | $207.04 | $877 | −12.3% |
| Oct 5, 2026 (all-time high) | $243.37 | $746 | −25.4% |
So the people hurting most are the ones who chased the rally late. Anyone who has held since the early days of the AI boom has given back a chunk of gains, but is still sitting on roughly ten times their money. Market reports noted that Thursday’s drop erased the last of Nvidia’s gains for 2026.
What happened on November 5
The midterm results on November 3 gave Democrats control of both the House and the Senate. Markets actually rose the next day. Then on Thursday, everyone headed for the exits at once. “I’m getting flashbacks to 2008 or 2001,” Greg Taylor, chief investment officer at PenderFund Capital Management, told Bloomberg, referring to the housing and dot-com crashes.
The Nasdaq Composite fell 5.52% to 24,315, its worst day since April 2025, and closed about 10% below its October 6 record. That officially put it in correction territory. The Dow lost more than 1,833 points, and all 30 of its stocks fell. The Nasdaq 100 was hit even harder, with its worst drop since the COVID crash of March 2020.
The damage was concentrated in anything tied to AI infrastructure:
| Company | Why it matters | Thursday |
|---|---|---|
| IREN | AI cloud and data centers | over −14% |
| Applied Digital | AI data center builder | over −14% |
| CoreWeave | GPU cloud provider | about −10% |
| Qualcomm | Also missed on phone chip sales | −9.5% |
| Tesla | Musk backed Republicans heavily | up to −9% |
| GE Vernova | Power equipment for data centers | −7.5% |
| Meta | Huge AI spending plans | −4% |
UNILAD Tech also reported SanDisk and AMD falling 22% and 17% respectively, a sign that memory and chip suppliers are being priced as part of the same trade. The “Magnificent Seven” lost as much as $1 trillion in combined value, according to IIFL.
Why an election hit AI stocks so hard
The short answer is data centers. Opposition to giant AI facilities, mostly over electricity bills, water and land, became a real campaign issue this year. According to The National, voters rejected data center proposals in 39 of 40 local ballot measures. In Texas, Governor-elect Gina Hinojosa won in a Republican stronghold after vowing to halt new data center construction in the state.
Investors now expect more scrutiny from Washington too. “The theme we are watching most closely is AI scrutiny. We anticipate more congressional hearings on who pays for the power-hungry buildout,” Century Financial’s chief investment officer told The National. We broke down what a Democratic Congress can actually do about AI data centers earlier this week, and the honest answer is: less than the market seems to fear, but enough to slow things down.
That’s the crux of it. Nvidia’s valuation assumes years of customers buying its chips as fast as it can make them. Anything that delays new data centers, from permits to power hookups, pushes those purchases out. And the market had already been nervous that AI spending was running ahead of AI revenue. Nothing about Nvidia’s own business changed on Thursday. What changed was confidence in how fast its customers can build.
It didn’t stop at Wall Street
On Friday, the selloff hit Asia. Japan’s Nikkei dropped 7% shortly after the open. South Korea’s Kospi fell more than 8%, tripping a circuit breaker that halted trading for 20 minutes, and Taiwan’s main index dropped more than 8% as well. Samsung, SK Hynix and TSMC, the companies that make the memory and chips inside Nvidia’s AI servers, all came under heavy selling. Both markets pared some losses later as buyers stepped in.
The chip supply chain is tightly linked, which is why the data center building spree has been draining the world’s chip supply all year. When the buildout looks shakier, everyone in that chain gets repriced at once.
What this means if you own index funds
You don’t need to own Nvidia directly to feel this. Nvidia is one of the biggest weights in the S&P 500 and the Nasdaq 100, so most 401(k)s and broad index funds took a hit on Thursday. That’s worth knowing before you check your balance this weekend.
Close: $181.60
One-day move: about -9.3%
Value lost in one day: about $440 billion
All-time high (Oct 5): $243.37
Drawdown from peak: about -25%
It’s also a reminder of how much of this cycle ties back to memory and chip supply. Apple’s CEO just called memory prices “unprecedented”, and if the buildout slows, that pressure may finally ease for consumer devices. That would be one small upside to a very bad week for tech stocks.
