Shares surge more than 10% as OpenAI CEO highlights deep engagement with the AI chipmaker
Cerebras Systems (CBRS) shares surged more than 10% Monday morning after OpenAI CEO Sam Altman reaffirmed the artificial intelligence lab’s partnership with the chipmaker, providing a boost to a stock that has faced pressure in recent months.
“Cerebras is a close partner,” Altman wrote on X, adding that the companies have a “deep engagement pushing on the frontiers of speed.”
The comments followed discussion surrounding OpenAI’s GPT-5.6 Sol running in Ultrafast mode on Cerebras chips, as well as reported usage by quantitative trading firm Jane Street. The developments highlighted Cerebras’ potential role in providing high-speed AI computing infrastructure as demand for faster inference continues to expand.
Cerebras shares traded around $181 Monday, extending gains after declining from their mid-August levels following disappointing earnings and guidance.
The company went public in May and is attempting to establish itself as a significant competitor in an AI accelerator market dominated by Nvidia. Cerebras is best known for its unusually large wafer-scale processors designed to accelerate demanding artificial intelligence workloads.
Altman’s endorsement could strengthen investor confidence in Cerebras’ technology and commercial positioning, particularly as OpenAI continues expanding its computing requirements.
With AI infrastructure spending accelerating, investors will now be watching whether Cerebras can translate high-profile partnerships into sustained revenue growth and improved financial performance.
