On October 14, Cerebras Systems fell 5.08% in Regular Trading, trading at $141.95 per share, with turnover of $190 million.

The main catalyst in publicly available market information is continued pressure from a previously disclosed $1.365 million in-the-money put block, concentrated in a far-dated $170 strike and interpreted as a medium-term bearish positioning.

Recent market reports indicated that the bearish options trade remained a sentiment overhang even after earlier support from OpenAI CEO Sam Altman, who had described Cerebras Systems as a close partner. That partnership comment briefly lifted the stock in early October, but subsequent trading showed the positive effect faded, while the put-heavy flow continued to dominate risk appetite and reinforce downside pressure.
