OpenAI’s cozy partner Cerebras is on track for a blockbuster IPO
AI chipmaker targets $3.5B raise, already oversubscribed 3x ahead of pricing
Cerebras Systems, the AI chipmaker known for its Wafer-Scale Engine 3, is on the verge of a blockbuster IPO. The company plans to sell 28 million shares priced between $115 and $125, aiming to raise $3.5 billion and achieve a market cap of $26.6 billion at the high end. This would make it the largest tech IPO of 2026, surpassing all other listings this year. The offering is already heavily oversubscribed: banks report $10 billion in orders for the $3.5 billion block, signaling strong investor appetite that could push the final price above the range.
Cerebras’s ties to OpenAI give the IPO added significance. OpenAI is one of its largest customers and recently provided a $1 billion loan secured by warrants to buy over 33 million shares. Angel investors include OpenAI CEO Sam Altman, president Greg Brockman, former chief scientist Ilya Sutskever, and board member Adam D’Angelo. The company’s chip, the Wafer-Scale Engine 3, competes with GPUs by offering faster inference at lower power consumption, making it attractive for AI workloads. Major backers like Fidelity, Benchmark, and Coatue also stand to benefit.

Why It Matters
A successful Cerebras IPO validates specialized AI chips and could pave the way for OpenAI’s own public offering.
