Cerebras Systems completes $60 billion IPO after overcoming early technical failures
The company’s successful public offering follows a period of intense financial strain in 2019, when it spent nearly $200 million resolving critical engineering challenges to package a single, large-scale silicon wafer.
Cerebras Systems has completed its initial public offering, valuing the artificial intelligence chip manufacturer at approximately $60 billion. The listing, which closed on Thursday, marks a significant milestone for the company, with co-founders Andrew Feldman and his partner becoming billionaires following the debut. Cerebras now supplies AI inference chips to major technology firms, including OpenAI and AWS, having overcome early engineering hurdles that nearly led to the company’s collapse.
The road to the public markets was fraught with technical and financial difficulties. In 2019, when the company was three years old, Cerebras burned through nearly $200 million attempting to solve a complex packaging problem: adhering a single, large-scale silicon wafer into a functional chip. CEO Andrew Feldman reported spending approximately $8 million a month during this period of trial and error, regularly reporting failures to the board. The engineering challenge involved managing power delivery, heating, and cooling for a chip 58 times larger than standard processors, with no existing vendors or manufacturing partners to assist.
The microprocessor industry had historically increased speed by dicing silicon wafers into smaller pieces, but Cerebras’ founders believed using a whole, larger wafer as one giant chip would eliminate communication bottlenecks in AI compute power. The team had to invent custom machinery, such as a device to bolt 40 screws simultaneously without cracking the wafer. The technical breakthrough occurred in July 2019, when the team successfully powered on the packaged chip, a moment Feldman described as one of the greatest of his life.
OpenAI has played a pivotal role in Cerebras’ recent trajectory. The artificial intelligence firm loaned Cerebras $1 billion secured by warrants, which conditionally grant OpenAI about 33 million shares valued at over $9 billion at the IPO closing price of $279. As part of the loan deal, Cerebras agreed to a temporary restriction on selling its chips to specific OpenAI competitors, a move Feldman stated was designed to ensure OpenAI received capacity.
The company’s leadership brings prior experience in the hardware sector, with Feldman previously selling the cloud server startup SeaMicro to AMD for $334 million in 2012. OpenAI had previously attempted to acquire Cerebras, but talks fell through due to internal disputes among OpenAI’s founders, several of whom are angel investors in Cerebras. The company now faces the task of scaling its operations to meet demand from a growing number of model makers.
