Cerebras Systems, maker of the world's largest AI chip, has gone public on the NASDAQ at a $12 billion valuation, with shares surging 45% on the first day of trading as investors bet on alternatives to Nvidia's GPU dominance.

The Product

Cerebras's Wafer-Scale Engine 3 is a single chip the size of a dinner plate that can train AI models 100x faster than GPU clusters for certain workloads. Major cloud providers are adding Cerebras options.

Competition

The IPO intensifies competition in the AI chip market, challenging Nvidia's 80% market share in AI training hardware.
