Is Anthropic's $80 Billion Loss Real?

David Sacks says the widely reported $80 billion Anthropic loss is a phantom number, not a cash loss. Convertible notes issued to infrastructure partners such as Amazon were recorded as a loss as Anthropic's valuation rose, and the charge flowed into the income statement. Issuing equity instead would have left no such loss.

Anthropic raised around $110 billion and spent only about $9 or $10 billion across the life of the business. About $100 billion of cash or cash equivalents is still on the balance sheet. Gross margin is now something like 85%. For a given task, cost effectiveness improves roughly 10 times year over year, so the task gets about 10 times cheaper. Anthropic can cut the price of that task by about 50% and keep the rest of the efficiency in the margin. Token costs fall, and margins rise even faster. Anthropic calls those gains compute multipliers, from algorithmic improvements, better data curation, and more efficient architectures. The same answer can cost one tenth as much, or the savings can buy greater capability.

That record, in his view, partly refutes the past year's claim that open models will drive gross margin to zero, or that the business only works because venture capital subsidizes it. A lot of reasons support a pretty big lead for Anthropic.
