For investors hunting for the next breakout artificial intelligence (AI) stock, last month delivered a rare opportunity when Cerebras Systems (CBRS) stormed onto the public markets with one of the most explosive debuts in recent memory. Shares of the AI chipmaker soared nearly 70% on their first day of trading on May 14, catapulting its market capitalization to roughly $95 billion.
The company also secured the title of the largest IPO of 2026 and the biggest U.S. tech offering since Uber’s (UBER) debut in 2019. Much of the excitement stems from Cerebras’ position as a direct challenger to AI heavyweight Nvidia (NVDA). The California-based company develops wafer-scale engine chips roughly the size of a dinner plate, designed to accelerate AI workloads while offering an alternative to traditional GPU-based systems that depend on clusters of interconnected chips.
