Anthropic unlike OpenAI has reached an operating profit of 559 million, which is really telling. They've also been migrating enterprise customers to API pricing, which is likely part of why they've become so profitable.
SpaceX is selling their capacity to Anthrophic at a reduced rate in May and June [1]. It's possible that they're only profitable because of this discount.
Profitability claims don't really add up. They are not clear about what accounting methods they are using, and even if they might somehow show profitable quarter, they stated in their leak of numbers to WSJ that they might not end up the year being profitable.
This is just to pump their numbers for the IPO, profitability is nowhere close until we see the real numbers.
