Global Semiconductor Selloff Deepens as AI Valuation Concerns Rise

A global selloff in semiconductor stocks intensified this week as investors increasingly question the long-term sustainability of the artificial intelligence spending boom. The downturn was fueled by multiple headwinds, including reports of circular deals at Nvidia Corp. and significant advancements in domestic chipmaking technology within China. Leading manufacturers such as SK Hynix saw their stocks slide despite recent record profits, as the market begins to place a cap on valuations that were previously driven by unbridled AI optimism.

Momei Qu, Managing Director at PSP Growth, noted that for the first time, investors are seeing a tangible limit on the valuation of high-flying AI leaders. While hyperscalers continue to invest in custom silicon, the rise of Chinese competition and a potential saturation in infrastructure spending are reshaping the competitive landscape. This shift suggests that the initial phase of the AI gold rush, characterized by skyrocketing stock prices regardless of underlying fundamentals, may be transitioning into a more skeptical period focused on actual enterprise adoption and long-term utility.

The pressure on the sector is particularly evident in the memory chip market. Companies like SK Hynix, which recently launched a record $26.5 billion US offering, are now finding that even strong earnings results are missing the 'lofty' expectations set by the AI hype cycle. As China continues its push into advanced semiconductor manufacturing, the dominance of Western and South Korean firms faces a new geopolitical and economic challenge that is forcing a broad repricing of risk across the technology sector.
