Anthropic subscribers reportedly get 4X more compute per dollar than API buyers as margins hit 88%

SemiAnalysis estimates Anthropic's inference business runs at 88% post-compute margins, with 'heavily subsidized' subscriptions still served at 50% compute margin — meaning subscribers likely get over 4X the compute per dollar of API buyers. ARK's illustrative math: per $100 revenue, $12 inference compute and $18 R&D compute still leave a 70% margin; even assuming 70% of compute goes to R&D, blended company-level margin is 60%. The commentary suggests the market may be very wrong about frontier lab profitability and AI buildout sustainability.
