The selling pressure was primarily driven by a combination of multiple negative factors. On the news front, Nvidia ( NVDA) is in talks for AI infrastructure projects totaling over $750 billion and plans to provide approximately $250 billion in financing guarantees for OpenAI. The market is concerned about the potential credit risks associated with this 'circular financing' model, sending Nvidia's debt default insurance costs soaring, with the company closing down about 5% overnight.
Meanwhile, there are reports that Chinese state-owned enterprises have initiated the production of domestically developed immersion DUV lithography machines, with plans to deliver about 5 units this year, and SMIC, Hua Hong Semiconductor, and ChangXin Memory Technologies are on the list of first-batch customers. The chief strategist at Nomura Asset Management pointed out that China's progress in the field of semiconductor manufacturing equipment poses a substantial competitive threat to Japanese suppliers, which have long held a dominant position in the sector.
Overnight, the Philadelphia Semiconductor Index (SOX) closed down over 2%, hitting its lowest close since May 20. A sell-off triggered by anxiety over AI infrastructure investment is spreading from US stocks to the Japanese semiconductor sector.
