South Korea KOSPI Drop Sparks AI Chip Market Risk Alarm - The Cryptonomist

On June 27, 2026, South Korea's KOSPI index plummeted over 8%, triggering multiple circuit breakers and signaling one of the most severe market disruptions in recent years. The downturn was primarily ... Read original →

The KOSPI crash signals a localized deflation of the AI chip bubble, not an isolated market glitch. Technically, Samsung and SK Hynix’s delayed HBM4 ramp—hampered by EUV tool shortages—is throttling NVIDIA’s Blackwell Ultra deployment, forcing hyperscalers to recalibrate AI capex timelines. On compliance, diverging U.S.-South Korea export controls on advanced packaging and memory are inflating supply chain redundancy costs, destabilizing deliveries to customers in Taiwan, China and mainland China. Strategically, Micron is accelerating GDDR7 adoption, while Marvell and Infineon pivot toward automotive AI chips to sidestep consumer volatility. Over the next 12–24 months, expect brutal consolidation: second-tier memory players lacking vertical integration will likely be acquired, while firms mastering CoWoS or FOVEROS packaging will dominate the new stack. Retail buying masks institutional fears of overcapacity—AI chips are shifting from 'infinite demand' hype to 'structural surplus' reality.
