On September 14, Cerebras Systems fell 7.03% in regular trading, trading at 179.355 USD/share, with turnover of approximately $120 million.

On the news front, the broader semiconductor sector came under heavy selling pressure after Anthropic CEO Dario Amodei published an article calling for a slowdown in frontier AI model development, a stance echoed by prominent tech leaders. Bernstein analyst Stacy Rasgon noted the development would further weigh on semiconductor sentiment. Within the sector, Intel fell 7.38%, Micron Technology dropped 7.13%, AMD declined 6.25%, NVIDIA slid 4.19%, and Broadcom lost 4.16%, reflecting broad-based weakness that dragged on Cerebras.

Compounding the pressure, company insiders have been actively reducing their holdings. CTO Sean Lie exercised options and disposed of over 115,000 shares on September 4, while CEO Andrew Feldman sold approximately 244,657 shares in August at prices ranging from $196.20 to $210.21. The concentrated insider selling amid sector weakness amplified downside pressure on the stock.
