On October 12, Cerebras Systems fell 5.46% in regular trading, trading at $155.11/share, with turnover of $3.59 billion.

The decline was driven by a notable bearish options transaction. A large, $1.365 million in-the-money put option position was established at a far-month strike price of 170.0, signaling a concentrated bet on a mid-term pullback. This large order sentiment was broadly bearish, with nearly all significant capital directed toward put options, creating selling pressure on the stock.

The company, an AI infrastructure developer, is known for its unique wafer-scale engine processors, the only commercially available products of their kind, focused on enhancing compute efficiency for both AI training and inference. Despite recent comments from OpenAI describing Cerebras as a close partner, the positive sentiment failed to sustain the share price.
