Nova is trading 10.04% down now at $334.48 after calls from Anthropic, OpenAI, and xAI leaders to slow advanced-AI development pressured expectations for future AI infrastructure spending and semiconductor demand.

  • Reuters reported broad chipmaker declines, including Intel, AMD, and Marvell, confirming the move is primarily sector-driven rather than tied to a new Nova-specific announcement.
  • Semiconductor sentiment remains exceptionally weak, with SOXX down 5.54% during the open September 14, 2026 session.
