OpenAI CEO Sam Altman publicly reaffirmed the company's partnership with chipmaker Cerebras following market speculation. Concerns arose in October 2026 after reports suggested that OpenAI's new GPT-6.1 Sol model would initially launch on Nvidia hardware rather than Cerebras systems.
The partnership, announced on January 14, 2026, involves a multi-year commitment from OpenAI to purchase up to 750 megawatts of wafer-scale AI inference capacity. The deal was initially valued at over $10 billion, with estimates suggesting it could exceed $20 billion including extensions.
Cerebras hardware is intended to be integrated into OpenAI's inference stack through 2028 to improve response times for applications like ChatGPT. The companies position Cerebras as a complement to existing suppliers such as Nvidia and AMD, rather than a replacement.
Altman has been a personal investor in Cerebras since February 2017 and holds approximately 89,373 shares. This stake saw significant appreciation following the company's public listing in May 2026, highlighting his dual role as both a customer CEO and a long-term shareholder.
