TSMC is trading at $452.93, 3.3% down on October 9, as AI-spending concerns pressured chipmakers.

  • Reports put OpenAI’s annualized revenue at roughly $50 billion, below earlier estimates near $70 billion, renewing questions about AI spending durability.
  • The Philadelphia Semiconductor Index fell 3.4%, while major U.S. indexes were modestly higher; no TSMC-specific catalyst was clearly reported.
  • TSMC’s record third-quarter revenue rose 50% year over year; Friday’s decline extended the prior session’s selloff.
