POET Technologies is trading 6.78% down at $7.65 as semiconductor stocks sell off broadly after major AI leaders urged slower development of advanced AI systems.
- Reuters and CNBC reported similar pressure across AI-heavy technology shares, chipmakers and AI-related stocks on September 14, 2026.
- No clear company-specific catalyst was identified; the move is sector-driven.
- Slower AI investment could reduce future chip demand; the decline exceeds major-index weakness but matches the active semiconductor selloff.
