KIOXIA is trading 8.4% down at ¥56,670 as investors rotate out of memory-chip names amid renewed worries about AI infrastructure spending and a potential NAND flash oversupply.

  • The move follows Alphabet’s higher AI capex guidance, which has heightened fears that heavy spending may not translate into near-term returns, pressuring sentiment across semiconductor and data-center suppliers.
  • Market participants are increasingly concerned that the rapid expansion of AI infrastructure could lead to an eventual glut in NAND flash memory supply, impacting long-term pricing power.
