Cerebras IPO Hauls in $5.5B as Shares Surge 108%
Cerebras Systems completed its initial public offering on Thursday. The company raised $5.5 billion. It priced shares at $185 the evening before. That price beat the initial range of $115 to $125. Later, the range moved to $150 to $160. Cerebras also boosted the offering size to 30 million shares.
Shares started public trading at $385. That marked more than a double from the IPO price, a 108% increase. Retail investors drove the demand. The stock dipped just a bit after opening. By mid-day, it traded above $330 with strong volume.
Strong Market Debut
Even at the $185 IPO price, Cerebras hit a fully diluted valuation of $56.4 billion on its first trading day. That figure includes all shares. Co-founder and CEO Andrew Feldman held a stake worth almost $1.9 billion at that price per share. Co-founder and CTO Sean Lie's stake came to about $1 billion.
Prices above $300 would push the company's value and the founders' holdings much higher by day's end.
Cerebras, founded in 2016, builds massive chips tailored for AI workloads. The company created the Wafer-Scale Engine, the largest chip ever produced. This hardware aims to challenge Nvidia's dominance in AI computing. Cerebras focuses on both training large models and running inference tasks.

Rocky Road to Public Markets
Just one year earlier, an IPO seemed out of reach for Cerebras. The firm first filed paperwork in 2024. A big investment from Abu Dhabi-based G42 triggered a long review by the Committee on Foreign Investment in the United States, known as CFIUS. Investors worried about the setup. G42 made up nearly all of Cerebras's revenue at that time. The company paused its IPO plans.
Cerebras revived its public listing efforts in April. New financials helped. Revenue reached $510 million in 2025, almost double the prior year and up 76% year over year. Those sales came from a small group of customers. The company also flipped to profit. Net income hit $237.8 million, compared to a loss of nearly $500 million the year before.
Customer Wins and AI Focus
Those results drew investor interest. Cerebras positions itself as a key supplier for AI inference chips. Inference handles the compute work for models responding to user prompts. Customers include OpenAI in a complex circular arrangement. G42 remains a client. Saudi Arabia's Mohamed bin Zayed University of Artificial Intelligence uses the chips. Amazon Web Services also buys from Cerebras.
The IPO marks the first major tech listing of 2026. It sets a strong tone for the year amid growing demand for AI hardware.
