投资者正在大规模抛售AI芯片相关股票，引发市场广泛担忧。[1]韩国芯片制造商SK海力士和三星电子股价跌幅均超过10%，[1]韩国综合指数Kospi随之下跌至自4月中旬以来的最低水平。[1]
美国芯片巨头Nvidia也未能幸免，其股价下跌5%，收盘跌破200美元。[1]与此同时，Nvidia五年期信用违约互换（CDS）价格飙升，[1]反映出市场对其债务违约风险的担忧。投资者的不安情绪源于多个因素：一方面，Nvidia正与OpenAI讨论一项规模达2500亿美元的数据中心融资项目，[1]引发了对AI企业巨额借贷用于数据中心扩张可持续性的疑虑；另一方面，中国启动了深紫外光（DUV）芯片制造工具的量产，[1]这被视为对全球芯片竞争格局的潜在威胁。中国芯片设备制造商中微公司（CXMT）在上海交易所上市首日股价上涨466%，[1]进一步凸显了市场对芯片产业格局变化的关注。
Investors have triggered a sharp retreat from artificial intelligence-related semiconductor companies, with major chipmakers suffering significant losses. South Korean memory chip producers SK Hynix and Samsung Electronics both fell more than 10 percent [1], while South Korea's Kospi index declined to its lowest level since mid-April [1]. Nvidia, the dominant AI chip manufacturer, experienced a 5 percent decline in its share price, closing below the $200 mark [1].
The market turbulence reflects deepening concerns about the financial sustainability of the AI boom. Investors are worried about massive debt burdens taken on by major AI companies to fund data center expansions, with Nvidia and OpenAI reportedly discussing a $250 billion data center financing project [1]. The credit risk associated with Nvidia has risen notably, as evidenced by a surge in its five-year credit default swap spreads [1]. Adding to these concerns is China's launch of production for deep ultraviolet light, or DUV, chipmaking tools [1], a development that threatens the competitive advantage of existing global chip manufacturers. Meanwhile, China's CXMT surged 466 percent on its Shanghai stock exchange debut [1], signaling investor optimism around domestic chip manufacturing capabilities.
