Kospi Falls 3.7% as AI Doubts Hit Chipmakers and Korea's Biggest IPO of the Year Drops 30% on Debut
South Korea's main index led a broad Asian decline on Tuesday as investors questioned the financing and returns of artificial-intelligence spending ahead of results from Meta and Tesla. A Seoul data-centre company that raised the year's largest Korean IPO fell about 30% below its offer price on its first day.

The Asian sell-off
The Kospi fell 3.7% to 5,552.74 on Tuesday, AFP reported. SK hynix dropped 4.2% and Samsung Electronics fell 3%. Japan's Nikkei 225 lost 1.3% to 64,075, and Hong Kong's Hang Seng also fell 1.3%. Chart 1 compares the declines. The selling was concentrated in companies tied to AI hardware, which have led Asian markets for most of the year.
The AI question
The common thread was renewed concern about how AI investment is being financed and when it will pay off, according to market commentary reported by AFP. Meta and Tesla report results this week, and investors want evidence that spending on data centres is producing revenue. No single headline drove Tuesday's move. It is better described as a reassessment of crowded positions than as a reaction to one event.
Elice's difficult debut
Elice Group, a Seoul company offering data-centre and AI services, fell about 30% below its offer price of 90,500 won on its Kosdaq debut, according to CNBC, Bloomberg and the Straits Times. The company raised 201.1 billion won, about $150 million, in South Korea's largest initial public offering of 2026. The subscription book had been heavily oversubscribed, which makes the first-day fall more striking.
One data point, not a verdict
A weak debut does not prove an AI bubble. IPO pricing reflects many factors, including the share of retail investors, lock-up rules and a falling market on the day. Elice listed into one of the worst sessions for Korean tech this year. Still, the gap between strong subscription demand and the trading result suggests that investors are becoming more selective about valuations for AI-infrastructure companies.
Wall Street's Monday
The Asian decline followed a firmer day in New York. On Monday the Nasdaq Composite rose 1.11% to 26,430.89 and the S&P 500 gained 0.41% to 7,690.73, while the Dow was little changed, down 0.07%, CNBC reported. Chip stocks ended a nine-day losing run. The rebound did not carry into Asia, which suggests investors there were positioning for this week's earnings rather than following New York.
Europe joins in
European shares also slipped. The STOXX 600 was down about 0.6% at midday on Tuesday after gaining nearly 1% on Monday, Reuters reported. US stock futures were mostly lower before the open, according to the Associated Press, with AI-linked stocks again under pressure and oil prices higher.
Why Korea is exposed
Korea's market is heavily weighted toward memory chipmakers. SK hynix and Samsung account for a large share of the Kospi, so any doubt about AI demand for high-bandwidth memory hits the whole index. That concentration amplified Tuesday's fall compared with Tokyo and Hong Kong.
What to watch
Meta's and Tesla's results will test whether AI spending plans are intact. For Korea, the next sessions will show whether Elice finds a floor and whether foreign investors keep selling chip stocks. The Journal will report closing levels and avoid reading a single session as a trend.
