Cerebras raises $5.5B, kicking off 2026’s IPO season with a bang

Cerebras raised $5.5 billion in its IPO on Thursday, pricing shares at $185 Wednesday evening, way higher than its range ($115 to $125, later raised to $150-$160), even as it increased the size of the offering to 30 million shares.

And pre-market trading indicates that shares are going to open with a giant pop, as retail investors bid up the price to grab them. (We’ll update this story after trading begins.)

Even at the IPO price, the company enters its first day of trading at a fully-diluted valuation of $56.4 billion (meaning, accounting for all shares). Co-founder CEO Andrew Feldman’s stake at $185/share is worth nearly $1.9 billion, while co-founder CTO Sean Lie’s stake weighs in at about $1 billion.

A year ago, it looked like this day would never happen for Cerebras. The Nvidia competitor, which designed its giant chip from scratch, purpose-built for AI, had first filed to go public in 2024. But concerns about a large investment from Abu Dhabi-based Group 42 mired the IPO in an endless review from the Committee on Foreign Investment in the United States (CFIUS). Investors were also cool about its financials: Group 42 accounted for almost all of Cerebras’s revenues. So those IPO plans were shelved.

IPO ambitions reappeared in earnest in April when the company was able to report about double the revenues: $510 million in 2025 (up 76% year-over-year), and from a handful of customers. It also reported a massive swing to a profit — to $237.8 million in net income — compared to losing nearly half a billion the year before.

Investors began salivating.

Cerebras has now come out as a major contender for supplying chips for inference — the ongoing compute processing required for models to answer prompts — and now counts OpenAI (in a complicated circular-deal relationship), G42, Saudi’s Mohamed bin Zayed University of Artificial Intelligence and Amazon Web Services as customers.
