Cerebras Systems is an AI chip and hardware company best known for building the world's largest single "wafer-scale" AI processor, an approach that avoids the networking overhead of linking together large clusters of smaller GPUs. The company was founded in March 2016 by Andrew Feldman alongside Gary Lauterbach, Michael James, Sean Lie, and Jean-Philippe Fricker.
Cerebras went public on Nasdaq in May 2026 under the ticker CBRS, pricing its IPO at $185 per share and raising $5.55 billion, with shares climbing roughly 68 percent on their trading debut to imply a market capitalization near $67 billion. The listing followed a $23 billion private Series H valuation earlier in 2026, marking one of the largest AI-hardware public offerings to date.
