A fresh bout of skepticism around artificial intelligence investments shook global markets on Tuesday, sending technology stocks sharply lower and triggering a dramatic sell-off in South Korea. Investors pulled back from semiconductor and AI-linked companies as concerns over stretched valuations collided with expectations of higher interest rates.
The tech-heavy Nasdaq Composite dropped 2.21%, while the S&P 500 lost 1.44%. The Dow Jones Industrial Average, which carries less exposure to major technology firms, edged down just 0.1%. The decline extended Monday’s losses, suggesting that investors are becoming less willing to overlook risks after months of AI-driven gains.
Semiconductor Stocks Lead the Retreat
Chipmakers bore the brunt of the selling pressure. Nvidia fell roughly 4%, while Micron Technology plunged 13%. Marvell Technology dropped 9%, reflecting broad weakness across the semiconductor sector. Oracle also extended its recent slump, falling more than 5.5% and bringing its monthly decline to about 27%.
The weakness spread beyond Wall Street. Japan’s Nikkei 225 slid 3.6%, while SoftBank shares tumbled 15%, underscoring how closely global markets remain tied to AI-related growth expectations.
Despite the sell-off, the broader semiconductor industry remains on solid footing. According to the World Semiconductor Trade Statistics (WSTS) organization, global semiconductor revenue is projected to reach $700.9 billion in 2025, an 11.2% increase from the previous year, driven largely by AI, cloud infrastructure, and advanced computing demand.
James Reilly, senior markets economist at Capital Economics, said the sharp swings in technology stocks may indicate excessive enthusiasm has built up in parts of the market. A healthy correction, he suggested, could help investors distinguish between companies benefiting from sustainable AI adoption and those riding speculative momentum.
South Korea Hit by Panic Selling
The market reaction was even more severe in South Korea. The Kospi index plunged 10%, forcing authorities to activate a circuit breaker and pause trading for 20 minutes in an effort to restore order.
Leading chip manufacturers SK Hynix and Samsung each fell more than 12%, dragging the broader market sharply lower. Because semiconductors play a central role in South Korea’s economy and export sector, weakness in AI-linked stocks quickly spilled across the market.
Rising Rates Add to Investor Concerns
Market sentiment has also been pressured by shifting expectations around monetary policy. Last week, Federal Reserve Chairman Kevin Warsh reaffirmed the central bank’s commitment to controlling inflation, remarks that many investors interpreted as opening the door to further rate increases later this year.
Analysts say the market’s focus is moving away from geopolitical headlines and back toward corporate spending trends, valuation levels, and the impact of higher borrowing costs on future earnings. As GrowBusinessMag and other market observers have noted, enthusiasm for AI remains strong, but investors are increasingly demanding clearer evidence that massive technology investments will translate into long-term profits.
Outlook
The AI boom remains one of the market’s most powerful themes, but recent trading shows investors are reassessing how much future growth is already reflected in stock prices. With interest-rate uncertainty lingering and technology valuations under closer scrutiny, volatility across semiconductor and AI-related shares is likely to remain elevated in the near term.
