October 13, 2026 — Shares in companies linked to artificial intelligence and memory chips have come under pressure in global financial markets. Investors are concerned that technical advances by Chinese manufacturers could increase competition in the semiconductor industry.
According to Reuters, South Korea's technology-heavy KOSPI index fell significantly following reports of progress at China's memory-chip company CXMT. Shares in major semiconductor manufacturers also faced selling pressure.
The market reaction reflects not only new technology but also uncertainty about potential returns on the large sums being invested in artificial intelligence and about company valuations.
Falling share prices do not mean demand for artificial intelligence has disappeared. Markets change throughout the day, and intraday declines should not be presented as final closing figures.
