SK Hynix and Samsung Plunge on Broadcom AI Financing Warning

Yahoo Finance ·

South Korean semiconductor equities suffered steep losses on Tuesday following financing warnings from executives at Broadcom and Intel regarding artificial intelligence infrastructure. In Seoul trading, Samsung Electronics plummeted 8 percent, while SK Hynix retreated 4 percent. The intense sell-off triggered a temporary trading halt on the benchmark KOSPI index. Meanwhile, according to IDC data, Nvidia's share of China's data-center AI chip market declined to 34 percent in the first half of 2026, while Huawei captured 28 percent as domestic competitors gained significant ground amid ongoing export restrictions.

Broadcom CEO's funding concern remarks and IDC's release of China market share data exerted direct selling pressure across the global semiconductor sector. The 8% plunge in Samsung Electronics and the 11.4% crash in KORU reflect market caution regarding overheating AI infrastructure investments, while NVIDIA's 44% slump in China shipments and Huawei securing a 28% market share demonstrate the blow that geopolitical risks and intensifying competition deal to earnings.

Going forward, the sustainability of AI demand and whether big tech companies maintain their capital expenditures (CapEx) will serve as key rebound indicators. The bullish scenario involves bargain hunting inflows upon confirmation of continued big tech AI investments, whereas the bearish scenario entails further valuation declines driven by rising financing costs and intensifying competition in China. Investors must closely monitor earnings guidance from major semiconductor firms and indicators related to AI infrastructure investment.
