KOSPI Plunges on July 2 After Meta’s Cloud Announcement
On July 2, 2026, the KOSPI fell over 6 % intraday and closed 7.9 % lower after Samsung Electronics and SK Hynix each dropped more than 8 %, prompting a five-minute circuit-breaker halt.
AI-Driven Rally and Profit-Taking Pressures
The market had surged on AI-driven memory demand, lifting Samsung and SK Hynix over 200 % year-to-date, but analysts warned that rapid gains made the index vulnerable to profit-taking and a possible slowdown in AI infrastructure spending.
Key Figures and Groups
Samsung Electronics and SK Hynix are the dominant South Korean memory producers. Meta Platforms announced a cloud-computing venture. Analysts Fabien Yip (IG), Zavier Wong (eToro) and Jing Jie Yu (equity analyst) provided market commentary.
Timeline of the Two-Day Collapse
July 1: KOSPI opened higher, closed down 2.04 % at 8,303.41 after June exports rose 70.9 % YoY. July 2: Meta’s cloud news spreads, KOSPI loses 531 points intraday, circuit breaker triggers, close at 7,722, a 7.9 % drop.
Data and Statistics
Samsung fell 8.11 % to KRW289,000; SK Hynix fell 8.28 % to KRW2,348,000. KOSPI lost 531.30 points (?6.4 % intraday) and closed 7.9 % lower. June semiconductor exports grew 70.9 % YoY, the strongest since 1978. Morningstar raised fair-value estimates for both chipmakers.
On-the-Ground Reports: Circuit Breaker
The Korea Exchange halted program selling at 9:07 a.m. for five minutes after KOSPI futures fell over 5 % and the index slipped below the 7,700-point level, providing a brief market pause.
Official Statements and Responses
Analysts linked the sell-off to profit-taking and to concerns that AI-related memory demand may soften as data-center builds slow. Yip warned of rising volatility ahead of U.S. payrolls. Wong cautioned that AI infrastructure spending could decelerate after the current build-out wave. Yu noted the memory upcycle remains strong but stressed valuation reliance on pricing duration. Morningstar’s upgrade signals confidence in earnings despite short-term turbulence.
Criticism and Opposition
One analyst camp sees the plunge as an overreaction, pointing to June’s robust export surge and ongoing global chip demand. Another camp views Meta’s cloud move as a warning sign, suggesting future AI hardware spending may soften and valuations could be overstretched.
Conflicting Reports and Gaps
Sources report a 6 % intraday decline versus a 7.9 % closing loss, creating a discrepancy in the magnitude of the fall. Analysts also differ on cause, with some emphasizing profit-taking and others highlighting AI-capacity overhang.
