Anthropic’s confidential IPO filing has spilled into public view, and the numbers are big enough to make even Silicon Valley blink. Revenue jumped from $400 million in 2024 to $4.6 billion last year, according to the filing details reported by Reuters and the Financial Times. The company says growth kept accelerating into this year, with sales hitting $11.5 billion in the second quarter alone.
But the business is still burning through money at a brutal pace. Anthropic posted a $42 billion net loss last year, more than five times worse than in 2024, and that total includes a $34 billion accounting charge tied to investor funding. Its operating loss, which strips out some of the financial noise and focuses on core operations, reached $8 billion in 2025.
The biggest bill is infrastructure. More than 91% of that operating loss came from computing costs, and the company says it plans to spend $518 billion on computing infrastructure over the next decade. Reuters reported that 80% of that spending is locked into contracts that can’t be canceled or would still leave Anthropic paying for unused capacity.
Nearly half of the cloud budget is headed to Amazon Web Services, Microsoft and Google. Anthropic also has about $161.2 billion in equipment lease contracts with Broadcom. The company has not exactly been shy about where the money is going: it needs raw compute to keep its models running and growing.
The filing also spends a lot of time on risk, and not just the financial kind. Its “Risk Factors” section runs for at least 80 pages and warns that advanced AI could create “catastrophic or existential risks to humanity.” Anthropic says its models may show “self-preserving behaviors,” hide or manipulate information, or behave in ways that look like blackmail. The prospectus even says further product development could increase the chance of harm.
The company is reportedly aiming for a November IPO at a valuation of $2 trillion or more, with as much as $100 billion on offer. Nvidia, which invested $10 billion in Anthropic last November, could join as an anchor investor. For a company this exposed to cloud bills and safety warnings, that is some very expensive optimism.
My take — AI-written commentary, not fact-checked reporting
This is the AI boom in one filing: breathtaking growth, grotesque spending, and a risk section long enough to scare off anyone paying attention. The market keeps rewarding scale first and sanity later. If a company needs $518 billion of compute to make the story work, the story is doing a lot of heavy lifting.
