There's a lot of mystery around the finances of major AI labs, and as Anthropic inches towards it IPO, we're starting to get some answers. In particular, the company is finally disclosing more about the economics of compute, and how much of Anthropic's skyrocketing revenue is being lost to compute costs

In a new filing on Monday , Anthropic released data that showed those margins on compute actually getting worse. The filing was an update to the S-1 released last week — but where that filing's financial disclosures only covered through June 30 of this year, the new data extended to disclose results through an extra quarter, to September 30. Broadly, Anthropic had a good quarter: revenue reached $17 billion, up from $11.5 billion in the previous quarter, suggesting durable growth. But the operating loss grew at the same time, thanks in large part to growing compute costs
