US chip startup Cerebras Systems made a spectacular entry on the Nasdaq Thursday, with its shares surging as much as 66 per cent from an initial price of $185, briefly reaching $307.35.
At one point during trading, the company’s market value hit $80 billion, marking one of the most notable debuts of 2026. The strong performance reflects heightened investor appetite for equities linked to the artificial intelligence (AI) boom.
Cerebras raised $5.55 billion in its initial public offering (IPO), the largest of the year so far, demonstrating the market’s growing confidence in AI infrastructure providers. The company had already increased its target price twice before listing, underscoring robust demand.

Cerebras specialises in giant processors, known as wafer-scale systems, designed to develop and run AI models efficiently. Since the release of OpenAI’s ChatGPT three years ago, the AI infrastructure market has expanded rapidly, reaching a new peak this year. In January, OpenAI committed to purchasing a large number of Cerebras processors under a deal valued at more than $10 billion.
As part of this agreement, Cerebras granted OpenAI warrants—derivative products convertible into shares under certain conditions. If all criteria are met, OpenAI could end up controlling over 10 per cent of Cerebras’s capital, cementing a significant partnership between the AI developer and the chipmaker.
The debut highlights not only investor enthusiasm for AI-related technologies but also the increasing role of high-performance computing in supporting the next generation of AI innovations.
Cerebras’s IPO demonstrates how infrastructure companies that power AI are becoming central players in the global tech landscape.
