Shares of major Asian chipmakers plunged on Monday, leading a broader global technology selloff as investors questioned whether the AI investment boom can be sustained.
According to the Financial Times, Samsung Electronics fell 10%, while SK Hynix dropped 15%, its biggest decline on record, helping trigger a market-wide trading halt in South Korea.

The selloff came despite TSMC reporting a 36% year-over-year increase in quarterly sales, highlighting that demand for AI computing remains strong.
Analysts say investors are becoming increasingly concerned that chipmakers’ rapid expansion could eventually lead to oversupply. As semiconductor companies now account for a significant share of both US and Asian stock indexes, any slowdown in AI spending could have a broad impact on global markets.
Investor takeaway: Strong AI demand continues to support chip sales, but rising concerns over valuations and future supply are increasing volatility across the semiconductor sector.
