Cerebras Systems made a dramatic stock market debut on May 14, 2026, with shares soaring 68.2% to close at $311.07 after pricing at $185. The IPO raised $5.55 billion, making it the largest of the year so far. The company, known for its wafer-scale AI chips, is positioning itself as a direct competitor to Nvidia in the high-growth AI inference market. Customers include OpenAI, Amazon, and Meta, and its CS-2 and CS-3 supercomputers are powered by the WSE-3 processor.

Cerebras has seen explosive revenue growth, jumping from $24.6 million in 2022 to $510 million in 2025 — a 76% year-over-year increase. However, the company is not yet profitable, reporting a $145.9 million operating loss in 2025 due to heavy R&D spending. Despite this, it achieved near break-even operating cash flow, signaling improving financial discipline.

With a market cap of $67 billion, Cerebras is far smaller than industry giants like Nvidia ($5.7 trillion) and TSMC ($2.2 trillion). Still, its performance and technology have drawn investor interest. The stock is likely to be added to the S&P 500 and Nasdaq-100, which could bring further passive fund buying. While the future looks promising, the challenge will be scaling profitably in a fiercely competitive sector.
