Cerebras raises $5.5B, then stock pops $108%, in the first huge tech IPO of 2026
Blockbuster IPO Sets Records
On Thursday, Cerebras Systems launched 2026’s IPO season in spectacular fashion by raising $5.5 billion. The company priced its shares at $185, significantly above earlier projections, after increasing its offering to 30 million shares. When public trading opened, the excitement was palpable—shares soared to $385, representing a 108% jump. Although the stock later settled to around $311 by market close, the momentum carried into after-hours trading.
At the IPO price, Cerebras achieved a fully diluted valuation of $56.4 billion, but its closing share price pushed its market value to $66 billion. CEO Andrew Feldman and CTO Sean Lie saw their stakes soar in value, reflecting the enthusiastic investor response.
A Remarkable Turnaround
The journey to this IPO was far from straightforward. Just a year earlier, Cerebras—a company known for its custom-built AI chips and seen as a challenger to Nvidia—faced major headwinds. After originally filing for an IPO in 2024, concerns regarding a significant Abu Dhabi-based investor triggered scrutiny from U.S. regulators and skepticism about its heavy reliance on a single customer. Plans for a public debut were put on hold.
Momentum returned in April, however, as Cerebras unveiled impressive financials: revenue jumped 76% year-over-year to $510 million in 2025, coupled with a dramatic swing to a $237.8 million net profit, following a significant loss the prior year. This transformation reignited investor interest and paved the way for its IPO.
Major Industry Players as Customers
Cerebras is establishing itself as a key provider of AI inference chips—hardware essential for running advanced machine-learning models. Its growing customer list includes OpenAI, Group 42, Mohamed bin Zayed University of Artificial Intelligence, and Amazon Web Services, positioning it at the forefront of the rapidly expanding AI hardware sector.
