Key facts
- South Korea's stock market fell to its lowest level in three months.

South Korea’s stock market slid to its lowest level in three months on Tuesday as a sell-off in artificial intelligence shares intensified, according to the Guardian. The decline was led by heavy losses among the country’s biggest chipmakers.
Samsung and SK Hynix, two of the largest names in the global memory chip industry, each fell by more than 10%. The steep drops reflected mounting investor unease about the outlook for companies tied to the AI boom.
The Guardian reported that investors continued to ditch chip stocks throughout the day, extending a broader retreat from AI-linked equities.
Behind the sell-off are rising concerns about the huge amounts of borrowing among AI companies to fund their datacentre expansion plans. Investors have grown wary that the scale of spending may not be sustainable.
Renewed fears over Chinese competition added to the pressure, according to the Guardian, compounding worries about how much AI-related demand will ultimately materialise for chipmakers.
The moves left South Korea’s benchmark at a three-month low, underscoring how sensitive the market has become to shifts in sentiment around AI spending.
Why it matters
South Korea is home to some of the world's most important chipmakers, so sharp falls in Samsung and SK Hynix ripple through global technology supply chains and investor portfolios. The sell-off signals growing doubt about whether the enormous, debt-fuelled spending on AI infrastructure can be sustained.
