Cerebras Systems announced plans for a major IPO, selling 28 million shares priced at $115-125 per share. This would raise $3.5 billion and value the company at $26.6 billion at the high end, up from its February $23 billion valuation in Series H funding. The AI chipmaker produces the Wafer-Scale Engine 3, competing with GPU-based AI chips by offering faster inference processing with lower power consumption. Notable angel investors include OpenAI's Sam Altman, Greg Brockman, Ilya Sutskever, and board member Adam D'Angelo. Major institutional investors include Alpha Wave, Benchmark, Eclipse, Fidelity, and Foundation Capital with over 5% stakes. If successful, this would be 2026's largest tech IPO and could signal market appetite for other potential offerings from SpaceX, OpenAI, and Anthropic.
