KIOXIA is trading 9.8% down at ¥55,800 as investors rotate out of memory-chip names amid rising concern about AI infrastructure spending returns and a potential NAND oversupply.

  • The selloff follows Alphabet’s aggressive AI capex plans, which have sparked broader market worries that heavy infrastructure investment may not quickly translate into bottom-line profits for hardware suppliers.
  • Sentiment in the semiconductor sector has weakened as analysts evaluate the risk of a NAND supply glut alongside the high capital requirements for AI-related hardware development.
