Cerebras Stock Surges After Altman Calls Them "Close Partner" - Cerebras Systems (NASDAQ:CBRS)

Cerebras Systems shares surged Monday after OpenAI CEO Sam Altman posted that the company is “a close partner.” Cerebras Systems Inc. (NASDAQ:CBRS) was up 9.73% to $182.63 at the time of publication, following reports that OpenAI’s newly unveiled GPT-6.1 Sol Ultrafast model would not run on Cerebras chips. Altman’s social media response countered that speculation, saying the two firms have “a deep engagement pushing on the frontiers of speed.” The jump also comes after a difficult period for CBRS, down about 14.6% over the past month and still below its $185 IPO price. Earlier declines were linked to post-IPO share unlocks.
