The AI-driven selloff has triggered a sharp correction in global semiconductor stocks, with the Philadelphia Semiconductor Index down over 20% from its June high and the KOSPI falling more than 40% from its peak. This has raised fears of a broader market downturn, increased volatility, and prompted concerns about the financial stability of tech companies heavily invested in AI infrastructure, potentially affecting credit markets and investor sentiment.
A global selloff in AI-related semiconductor stocks intensified in late July 2026, triggered by concerns over the sustainability of massive AI infrastructure spending, rising competition from Chinese chipmakers, and the financial strain on major tech companies. South Korea's KOSPI plunged over 10% on July 28 and continued falling the next day, with Samsung Electronics and SK Hynix suffering double-digit losses. The rout spread across Asia, hitting Japan's Nikkei, Taiwan's TAIEX, and other regional indices. Key catalysts included reports of China's progress in domestic DUV lithography, the strong debut of Chinese memory chipmaker ChangXin Memory Technologies, and Nvidia's reported talks to provide $250 billion in financing guarantees for OpenAI. Major US chip stocks like Micron, AMD, and Applied Materials also fell sharply. Fitch Ratings warned that an AI market correction poses a significant global credit risk, while concerns about free cash flow at Alphabet and Meta added to investor anxiety. The selloff occurred ahead of earnings from Microsoft, Meta, Amazon, and Apple, and a United States — Federal Reserve rate decision.
