Recent work from SemiAnalysis estimates Anthropic could have 88% margins after compute costs for their inference business. That INCLUDES the "heavily subsidized" subscription business, which is still served at a 50% compute margin.
But what about training costs? Even if you assume 70% of compute is going towards R&D, you still blend to a 60% company level margin.
Add in your assumptions for data & talent costs and you can start to see how the market could be very wrong about frontier lab profitability and the sustainability of the AI buildout.
