OpenAI's own estimate is a $14B loss in 2026[1]. Anthropic is aiming to break even this year (and some of that is probably due to Cowork, so that at least isn't unreasonable). So it may be revenue, but it isn't profit, yet...
Profit is what you do when you're not trying to grow. Name a time in history when a company with an industry-defining product with huge demand failed under the weight of cash flow, or regulation.
If we judged all startups by the same standards (in terms of revenue to debt ratios), many of today's established companies would have been "failures" at the same point in their life cycle.
