Cerebras Systems IPO: Stock price will be closely watched today as AI chipmaker goes public on the Nasdaq

Today is an important day in the 2026 IPO landscape: Cerebras Systems Inc. is making its much-anticipated market debut. While not a household name like Nvidia, Intel, or TSMC, Cerebras is a chipmaker that is rapidly becoming a critical player in the AI semiconductor space. And investors will be casting a keen eye on how its stock performs in the early days of trading, looking for hints about how other, even more anticipated AI-related listings may play out later this year. Here’s what you need to know about Cerebras and its initial public offering: What is Cerebras Systems? Cerebras Systems is an AI semiconductor company headquartered in Sunnyvale, California. It was founded in 2015 by Andrew Feldman, Gary Lauterbach, Michael James, Sean Lie, and Jean-Philippe Fricker. Feldman is the company’s CEO. The company specializes in making the largest—quite literally—computer chips in the world, chips that are optimized for running AI tasks. While most computer chips are made from large wafers that are then divided to make smaller, individual chips, a single Cerebras chip is the entire wafer. As Fast Company previously reported when it named Cerebras one of the most innovative AI companies of 2026, the large size of its chips means they can perform AI tasks much more quickly—up to 70 times faster than the GPUs that many AI systems run on today. “The large square chip packs a lot of processing power and memory on one piece of silicon, so almost no time is wasted routing data between separate chips,” Fast Company’s Mark Sullivan previously noted. “That makes it highly effective at processing data from commercial AI applications that require massive throughput and very fast response times.” Cerebras’s customers include pharmaceutical companies like AstraZeneca and GlaxoSmithKline, as well as tech firms like G42, IBM, Meta, Mistral, Notion, and Perplexity. Most recently, Cerebras inked a $20 billion deal with ChatGPT maker OpenAI. When is Cerebras Systems’ IPO? Cerebras Systems
