A broad selloff in AI-linked chip stocks intensified on Tuesday, extending pressure across Asian markets after South Korea’s Kospi dropped more than 10%. The decline added to a difficult week for semiconductor shares as investors reassessed how long the artificial intelligence spending boom can keep supporting high valuations.

The weakness was not limited to one market. Chipmakers in South Korea and Japan were among the stocks hit hardest, while the negative mood also spread to Europe. The pullback reflects growing concern that expectations for AI-related demand may have run ahead of what companies can realistically deliver in the near term.

Another factor weighing on the sector is rising competition from China. Investors are also watching whether increased Chinese activity in the chip space could pressure margins, market share, or future growth assumptions for established semiconductor names. That combination of demand worries and competitive pressure has deepened the retreat in AI-exposed stocks.

Markets are now looking ahead to earnings from some of Silicon Valley’s biggest companies for signals on AI spending plans and data center demand. Those results are expected to play a major role in shaping whether the latest chipmaker selloff stabilizes or gathers further momentum.
