Cerebras Systems filed its S-1 with the SEC on April 17 — the AI chip maker is heading for a Nasdaq listing. And the numbers in the prospectus are genuinely impressive.
From Loss to Profit
After posting a $485 million loss in 2024, Cerebras swung to a $87.9 million net profit in 2025. Revenue climbed 76% to $510 million. That’s a remarkable turnaround for a company that had to pull its first IPO attempt just a year ago.
The Wafer-Scale Bet
What makes Cerebras unique: the company builds chips that span an entire wafer — the WSE-3 (Wafer Scale Engine). Instead of cutting hundreds of small chips from a wafer, Cerebras uses the whole surface for a single, massive processor. This gives it theoretical advantages in AI training and inference that conventional GPU architectures can’t match.
The OpenAI Deal
The real bombshell in the S-1: Cerebras has a multi-year contract with OpenAI worth over $20 billion to deliver 750 megawatts of compute capacity through 2028. On top of that, OpenAI has extended a separate $1 billion loan to the company. This tells you something important: even OpenAI is diversifying away from pure Nvidia dependency.
Valuation and Timeline
The IPO is expected to value Cerebras at $22 to $25 billion, based on its Series H valuation of $23 billion from February 2026. The company is targeting roughly $2 billion in proceeds, with the listing window tracking May 2026.
Why This Matters for the AI Industry
We’re watching an IPO wave build across the AI sector. Cerebras, Anthropic, and OpenAI are all preparing to go public. It’s a sign that the AI industry is growing out of its pure startup phase. And for the chip market specifically, it means Nvidia is finally getting serious competition.
The big question remains: can Cerebras scale its wafer-scale approach beyond a handful of large customers? The OpenAI deal is a strong signal, but a company deriving a large chunk of its revenue from a single customer carries an obvious concentration risk.
