Chips as Big as Your Head: "Breaking down AI chipmaker Cerebras’ S-1"

The short explanation of the first half of our headline from January 15:
Chips As Big As Your Head: Cerebras Does Deal With OpenAI For $10 Billion+ In Computing Power

The Nvidia rival’s S-1 shows revenue of $510 million in 2025, up 76% from the year before. The filing also discloses a $24.6 billion order backlog — most of it tied to a December deal with OpenAI to supply 750 megawatts of AI compute through 2028, with options for nearly 3 gigawatts more by 2030. OpenAI advanced Cerebras a $1 billion loan and received warrants for 33 million near-free shares.

But Cerebras’ profitability is driven in large part by a paper gain.

In 2024, the company had signed a deal with the Abu Dhabi tech company G42 to sell its preferred shares, which resulted in the company recording a $401 million loss in 2024....
