TL;DR
Cerebras Systems almost went bankrupt in 2019 after spending nearly $200 million trying to develop a revolutionary large-scale AI chip. The company survived a critical technical and packaging challenge, leading to its current valuation of $60 billion following a successful IPO.
Cerebras Systems, now valued at approximately $60 billion following its IPO, nearly failed in 2019 after burning nearly $200 million trying to develop a revolutionary AI chip. The company’s founders faced a critical technical challenge that threatened its survival, but ultimately overcame it.
Founded in 2015, Cerebras aimed to create a single, massive AI chip by turning an entire silicon wafer into one processor, a feat no other company had attempted. By 2019, the company had invested roughly $200 million and was spending about $8 million per month on research and development. The primary obstacle was the chip’s packaging — a complex process involving cooling, power delivery, and data movement, which had stymied industry experts for decades.
According to CEO Andrew Feldman, the team encountered repeated failures, destroying numerous chips in the process. They had to invent new solutions, including a custom machine to bolt the wafer without cracking it. In July 2019, after years of trial and error, the team succeeded in manufacturing and installing the first fully packaged, functional mega chip, marking a pivotal moment for the company.
Why It Matters
This development is significant because it illustrates how a high-risk, innovative approach nearly led to the company’s failure but ultimately resulted in a breakthrough that contributed to its current valuation. The success of Cerebras’ mega chip has positioned it as a key supplier for AI giants like OpenAI and AWS, impacting the AI hardware landscape and setting a precedent for large-scale chip manufacturing.

Background
In 2019, Cerebras was still a relatively young company, attempting a pioneering approach that diverged sharply from traditional microprocessor design, which focused on increasing transistor density. The breakthrough in packaging and cooling was essential for scaling their design. Prior to this, industry leaders had repeatedly failed to produce such large, dense chips due to technical challenges. The company’s survival and subsequent growth have been closely linked to solving these engineering problems.
“We were spending about $8 million a month. At this point, we had incinerated nearly $200 million trying to solve one technical problem.”
— Andrew Feldman, CEO of Cerebras
“Watching a computer run is about as exciting as watching paint dry. But there we were watching lights flashing on the computer, stunned that we’d solved this.”
— Andrew Feldman, CEO of Cerebras
