Key findings
Growth and costs: Revenue rose roughly twelvefold to nearly $4.6 billion in 2025. Anthropic reported an $8.06 billion operating loss, up from $2.98 billion in 2024, and a $42 billion net loss; the available figures do not establish that the net loss was entirely cash spent on operations. Its prospectus describes $518 billion in cloud, computing and infrastructure obligations over coming years, not a single year’s spending.

Revenue mix and dependence: Amazon and Google’s cloud channels generated $2.16 billion—47% of 2025 sales. They distribute Anthropic’s products and collect customer payments, while also being major investors and computing partners. That puts access to customers, bill collection, financing and capacity in relationships with the same two companies.
3
Fees and concentration: Reuters’ analysis puts distribution fees paid to cloud platforms at more than $350 million. Nearly a quarter of revenue came from two customers, adding exposure if either reduces spending.
Risks: When partners handle billing, the timing of customer payments to Anthropic can matter for cash flow; reliance on investor-suppliers that also control sales channels raises potential conflicts over commercial terms and capacity. The cited evidence does not quantify a resulting cash-flow shortfall or establish an actual conflict of interest.
Marketplace accounting versus OpenAI: The available evidence does not set out the competing gross-versus-net reporting arguments or show that Anthropic’s marketplace sales and OpenAI’s reported revenue use the same accounting basis. Insufficient evidence to resolve the dispute or treat the headline revenue figures as directly comparable.
