Cerebras Systems Raises $5.5 Billion in Record 2026 AI IPO

Cerebras Systems Inc. executed the largest initial public offering of 2026, pricing 30 million shares at $185 on May 13 and debuting on the Nasdaq on May 14. Driven by investor demand that oversubscribed the offering more than 20 times, the stock surged 68% on its first day, opening at $350 and peaking at $385 before closing at $311.07. The offering raised approximately $5.55 billion, bringing the company's market capitalization to a peak of roughly $95 billion, though it settled between $67 billion and $83 billion by the following trading day.

The company specializes in Wafer-Scale Engine (WSE) processors, which are significantly larger than traditional GPUs and designed to accelerate AI inference. This technology has attracted major partners, including Amazon Web Services and OpenAI, the latter of which signed a multi-year compute agreement valued at over $20 billion. Ahead of the listing, Cerebras rebuffed acquisition attempts from Arm Holdings and SoftBank Group.

Financial growth has been rapid, with 2025 revenue increasing 76% to $510 million. However, analysts highlight significant risks regarding customer concentration, as over 85% of 2024 revenue came from UAE-based G42 and related entities. This relationship previously delayed a 2024 IPO attempt pending a national security review by the Committee on Foreign Investment in the United States. While some reports indicate a 2025 net income of $237.8 million, others note ongoing operational losses of $145 million.
