On October 9, Cerebras Systems fell 5.54% in regular trading, trading at $165.385/share, with Turnover of $544 million. Despite OpenAI CEO Sam Altman recently publicly calling Cerebras a close partner in an attempt to restore market confidence, the stock failed to stem its decline, reflecting persistent investor concerns over AI chip competition and heavy insider selling.

Market rumors last week suggested OpenAI would use Nvidia GPUs instead of Cerebras chips for the GPT-6.1 Ultrafast version, causing the stock to plunge nearly 20%. Barclays analysts noted that Nvidia remains solid in supporting GPT-6.1, while Cerebras remains a priority supplier under supply constraints. However, multiple Form 4 filings show continuous selling by executives including the COO and CTO, with one filing indicating the COO sold 270,845 shares on September 29 after exercising options.

Cerebras Systems Inc. is an artificial intelligence infrastructure developer whose core wafer-scale engine processor is the only commercially available product of its kind globally, focused on improving computational efficiency in training and inference scenarios.
