Cerebras rebounds 9% after Altman defends partnership amid OpenAI hardware shift
Cerebras shares jumped 9% on Monday after OpenAI CEO Sam Altman publicly reaffirmed the chipmaker as a 'close partner,' reversing a 20% weekly decline. The surge followed reports that OpenAI would use Nvidia GPUs for its GPT-6.1 Sol 'Ultrafast' mode instead of Cerebras hardware. Despite the rebound, Cerebras’ market cap has fallen to $43 billion from $95 billion since its May IPO, with analysts noting that revenue outlooks remain unchanged but margins are critical.
