Cerebras IPO soars 108%, raises $5.5B as AI chip demand explodes
AI chip maker Cerebras doubles on debut, hitting $66B valuation after massive IPO.
Cerebras Systems made a blockbuster debut on Thursday, raising $5.5 billion in its IPO after pricing shares at $185—well above the initial $115–$125 range, which had been raised to $150–$160 as demand surged. The stock opened at $385, a 108% jump, before settling to close at $311, giving the company a $66 billion market cap. Even at the IPO price, the fully diluted valuation was $56.4 billion. Co-founder CEO Andrew Feldman's stake was worth $1.9 billion at $185, and CTO Sean Lie's stake topped $1 billion. The strong performance comes after a year of delays caused by a CFIUS review over a large investment from Abu Dhabi's Group 42 and concerns about revenue concentration.
The company's financials have dramatically improved, with 2025 revenue of $510 million (up 76% year-over-year) and a swing to $237.8 million in net income from a nearly $500 million loss the prior year. Cerebras designs custom giant chips purpose-built for AI inference—the compute needed to run models after training. Its customer list now includes OpenAI (through a complex circular deal), G42, Saudi Arabia's Mohamed bin Zayed University of AI, and Amazon Web Services. The successful IPO cements Cerebras as a major contender to Nvidia in the inference market, as investors bet on continued explosive demand for specialized AI hardware beyond training.
