> It’s a not very well kept secret in the industry

I would rather say it's been a very well kept secret if it's true, which I highly doubt. It also makes absolutely no sense; so far, Anthropic has taken every opportunity they had to release good numbers. Why would they keep it secret if they were wildly profitable?

None of this makes any sense. The only thing that makes sense is that Anthropic isn't profitable at all, and is burning investor money to stay afloat. Else, why keep raising tens of billions and only release vague annualized numbers?

Genuinely, this makes no sense at all. If you want to convince people otherwise, you need more than just "oh, it's a secret, but we all know it."
