I can never quite tell if you're intentionally editorializing stuff like this, or if you genuinely believe things this misleading.
About $72B of that $80B loss is a noncash accounting charge from convertible debt, Anthropic’s rising valuation made the debt more valuable to investors, so the increase was recorded as a loss, not money actually spent operating the business.
So the very reason they "lost" all that money is *because* their valuation tripled.
