Chip Stocks Shed $1 Trillion as AI Selloff Hits Nvidia, SK Hynix, Samsung in US
Chip stocks shed $1 trillion in market value as the AI selloff hits US markets, with Nvidia falling 9%, SK Hynix crashing 17%, and Samsung dropping 12% as investors question the sustainability of massive AI infrastructure spending. The Philadelphia Semiconductor Index has fallen nearly 20% from its June highs, entering bear market territory. The selloff has wiped out gains from the AI boom that saw chip stocks rise 92% over the past 12 months. The massive decline reflects growing concerns about whether the AI infrastructure buildout will generate adequate returns for investors.

$1 Trillion Wiped Out
The world’s most valuable chip stocks have seen more than $1 trillion wiped from their market caps since market close on Friday, according to a CNBC analysis using FactSet data. In total, 20 of the world’s most valuable chip stocks lost $1.3 trillion.
| Company | Loss | Decline |
|---|---|---|
| Nvidia | $238B | -9% |
| SK Hynix | $176B | -17% |
| Samsung Electronics | $173B | -12% |
| TSMC | $119B | -4% |
| Micron Technology | $113B | -9% |
| AMD | $110B | -8% |
| Broadcom | $89B | -7% |
| Qualcomm | $67B | -6% |
The magnitude of the decline is unprecedented in the semiconductor industry, exceeding the 2022 chip selloff that wiped out $800 billion in value.
Nvidia Leads Decline
Nvidia saw a $238 billion rout since market close on Friday, making it the biggest single-day loss in the company’s history. The chip giant has been the poster child of the AI boom, with its stock rising over 200% in the past year.
The selloff reflects growing concerns that AI infrastructure spending may be “peaking faster than expected,” according to Charlie Dai, VP principal analyst at Forrester. Alphabet’s announcement that it would boost its 2026 capex forecast as it rushes to build new AI infrastructure has raised questions about return on investment.
Nvidia’s decline was particularly painful for investors who bought at the peak. The company’s stock had risen from $450 to over $1,000 in the past year, driven by demand for its AI chips. The correction has erased months of gains.
Memory Stocks Crushed
Memory chipmakers bore the brunt of the selloff, with SK Hynix falling 17% and Samsung down 12%. The declines came despite SK Hynix reporting a record quarterly profit that still missed analyst expectations.
“SK Hynix delivered strong results, but in today’s AI market, strong is no longer enough,” said Gary Tan, portfolio manager at Allspring Global Investments. “Investors were looking for additional catalysts.”
| Memory Stock | Decline | Key Issue |
|---|---|---|
| SK Hynix | -17% | Earnings missed expectations |
| Samsung | -12% | Market share concerns |
| Micron | -9% | Supply chain issues |
| Western Digital | -6% | NAND pricing pressure |
The memory sector has been particularly vulnerable because AI demand for high-bandwidth memory (HBM) has created capacity constraints, but investors are now questioning whether this demand will sustain at current levels.
Global Impact
The chip selloff spread across global markets:
- South Korea’s KOSPI: -6% (extends -11% Tuesday)
- Taiwan’s TAIEX: -3.8%
- Japan’s Nikkei: -2.6%
- Europe’s ASML: -1.8%
- China’s semiconductor index: -4.2%
South Korea’s KOSPI has now lost more than 33% in July, its worst monthly performance ever. The index had more than tripled over 12 months to June before the selloff began.
Why the Selloff Happened
Several factors contributed to the massive selloff:
- AI spending concerns: Investors question whether infrastructure buildout will generate adequate returns
- Chinese competition: CXMT’s IPO and DUV lithography progress threaten market share
- Earnings disappointment: SK Hynix results missed expectations despite record profit
- Valuations: Chip stocks had risen 92% in 12 months, creating froth
- Macro factors: Fed rate uncertainty and Middle East tensions
- Supply concerns: New capacity coming online may create oversupply
The combination of these factors created a perfect storm for chip stocks, triggering the worst selloff in years.
Recovery Signs
Despite the brutal selloff, some analysts see potential for recovery. JPMorgan said hedge funds have likely finished deleveraging from chip positions, suggesting the worst of the forced selling may be over.
UBS initiated coverage of SK Hynix with a Buy rating and a $204 price target, implying 61% upside from recent lows. The firm believes the selloff is overdone and memory chipmakers remain well-positioned for long-term AI demand.
| Analyst Firm | Rating | Outlook |
|---|---|---|
| JPMorgan | Neutral | Forced selling likely over |
| UBS | Buy SK Hynix | 61% upside potential |
| Morgan Stanley | Overweight | AI demand intact |
| Goldman Sachs | Buy Nvidia | $1,200 price target |
Investor Sentiment
Investor sentiment has shifted dramatically from optimism to caution:
- Fear & Greed Index: Moved from “Extreme Greed” to “Fear”
- VIX: Rose 45% to 28.5
- Put/Call Ratio: Increased to 1.2 (bearish signal)
- Short interest in chip ETFs: Up 35% from June lows
The shift in sentiment reflects growing uncertainty about the sustainability of AI-driven demand. Many investors who rode the chip rally are now taking profits or reducing positions.
China Competition
The rise of Chinese semiconductor companies has added pressure to the selloff. CXMT’s recent IPO and progress in DUV lithography technology have raised concerns about market share erosion for established players.
- CXMT: Successfully IPO’d, raising B for expansion
- SMIC: Advanced to 7nm process technology
- YMTC: NAND flash production increasing
- Yangtze Memory: HBM development progressing
While Chinese chipmakers still lag behind leaders in cutting-edge technology, their progress threatens to create oversupply in mature process nodes, putting pressure on pricing and margins.
Long-Term Outlook
Despite the short-term pain, most analysts maintain a positive long-term view on chip stocks. The AI infrastructure buildout is expected to continue for years, with semiconductor demand growing at 15-20% annually through 2030.
Key growth drivers include:
- AI training and inference chips
- High-bandwidth memory (HBM)
- Edge computing processors
- Automotive semiconductors
- 5G and 6G infrastructure
Frequently Asked Questions
How much value was wiped out? More than $1 trillion in market value was erased from chip stocks since market close on Friday, with Nvidia losing $238 billion alone.
Why did chip stocks crash? Investors fear AI infrastructure spending is peaking, Chinese competition is increasing, and valuations had become stretched after a 92% rally over 12 months.
Which companies were hit hardest? SK Hynix fell 17%, Samsung dropped 12%, Nvidia declined 9%, and Micron lost 9%.
Is the AI boom over? Analysts are divided. Some see this as a healthy correction, while others believe AI spending will continue to grow but at a slower pace.
Will chip stocks recover? Many analysts believe the selloff is overdone and expect recovery in Q4 2026 as AI demand fundamentals remain strong.
