Cerebras’s AI chip challenger gears up for a blockbuster IPO amid demand surge

Cerebras Systems, maker of the wafer-scale engine AI chip, is riding strong investor interest into an updated IPO plan on Nasdaq (ticker CBRS), boosting the offering to 30 million shares at $150–$160 and potentially raising up to $4.8 billion (up to $5.52 billion with over-allotments). A top-end valuation could reach about $48.8 billion. Notable recent contracts with OpenAI and AWS, plus a unique wafer-scale architecture (4 trillion transistors, 900,000 cores, 44 GB on-chip memory) aim to challenge Nvidia in AI hardware. Yet Cerebras is not profitable, with 2025 revenue of $510 million and a $345 million operating loss, and IPO valuation risks remain as the market weighs hype against fundamentals.
