Anthropic's IPO filing shows where its compute really goes

Anthropic's S-1: under a third of its $8.9B compute bill went to serving customers.

According to Tom's Hardware's analysis of the filing, Anthropic's first-half compute bill was $8.9B. Most of the rest went to training, research and running Claude internally. The compute split figures are Tom's Hardware's estimates.

Key details: Anthropic spent $2.4B serving customers against $16.3B in revenue. R&D costs are up about 5x year over year, with an estimated 66% or more of compute going to R&D. Minimum purchase commitments rose from about $55B to about $265.6B by the end of Q2, excluding equipment leases. The company warns margins may compress as new hardware arrives ahead of the revenue it will support.

Per CNBC, Anthropic aims to go public as a public benefit corporation and is seeking a valuation of $1.5T or more. Seven co-founders hold a single Class F share equal to 50.1% of voting power. Delaware corporate law attorney Lawrence Hamermesh, on the board's duty to balance purpose and profit: "Good luck." Separately, TechCrunch reports Anthropic announced reporting tools and pooled token budgets for tracking AI spending.
