Amid Stock Troubles, Is South Korea’s $880 Billion AI Infrastructure Buildout Under Threat?
South Korea's KOSPI index, significantly influenced by semiconductor giants Samsung and SK Hynix, has recently shed over a third of its value since a June peak. This downturn follows a period of substantial growth, with the index more than doubling between January 2025 and July 2026 due to AI-related momentum.
The KOSPI's recent decline, driven by a global slowdown in investor enthusiasm for AI stocks, is partly fueled by concerns over the substantial capital expenditures of hyperscalers. This market volatility is particularly impactful for South Korea, as Samsung and SK Hynix, central to the AI semiconductor buildout, account for approximately half of the KOSPI. The negative sentiment has extended beyond tech, reaching domestic automakers, suggesting a potentially prolonged bearish outlook.
Despite the market turbulence, South Korea unveiled ambitious AI infrastructure plans this summer, committing $880 billion to rejuvenate regional economies through chip production hubs, data centers, and robotics technology. While the KOSPI's value slipped by 35 percent after these late June announcements, the article does not directly state that these long-term strategic investments are under threat.
A longer-term view suggests resilience. Goldman Sachs, despite cutting its KOSPI target price by 25 percent, maintains a "strong buy" status, indicating that recent sell-offs have not significantly impacted the index's long-term growth trajectory. The South Korea AI infrastructure market is projected to expand considerably, from $2.58 billion in 2025 to $26.75 billion by 2035, driven by its advanced semiconductor market and AI computing sectors.
