Cerebras Systems: The Biggest Tech IPO Since 2019 with a 68% Surge
AI chipmaker Cerebras Systems made a remarkable entrance into the market on May 14, 2026. The company’s shares skyrocketed by 68% on the first day of trading, marking the largest U.S. tech IPO since Uber’s public debut in 2019.
The semiconductor company successfully raised $5.55 billion by selling 30 million shares at $185 each. This was significantly above its marketed range of $150 to $160. The shares opened at $350 and closed at $311.07, resulting in a market capitalization of approximately $95 billion. The IPO was more than 20 times oversubscribed, reflecting the intense investor interest in AI infrastructure companies.
Cerebras is known for designing wafer-scale AI processors. These chips, roughly the size of a dinner plate, contain around four trillion transistors. In 2025, the company reported revenue of $510 million with a 47% net margin. This impressive performance was primarily driven by major deals with OpenAI and Amazon Web Services. Following the market debut, CEO Andrew Feldman’s stake in the company was valued at $3.2 billion.
Despite the initial success, analysts have raised concerns. They caution that 86% of Cerebras’ 2025 revenue came from just two UAE-linked customers, which raises concentration risks. Following this cautionary note, the stock fell 10% on Friday as the initial enthusiasm cooled.
