Anthropic revenue jumps 1,200% to $33.2 billion ahead of IPO, but $104 billion loss raises questions

Anthropic’s revenue surged nearly 1,200% to $33.24 billion in the first nine months of 2026, but the AI startup’s latest financial disclosures reveal a staggering $104 billion net loss and nearly $900 billion in infrastructure commitments ahead of its highly anticipated IPO.

The numbers, disclosed Monday in an amended S-1 filing with the Securities and Exchange Commission (SEC), offer the clearest picture yet of the financial pressures facing the Claude maker as it prepares for a potential stock market debut.

Anthropic generated roughly $17 billion in third-quarter revenue, up 1,127% from the same period last year. That growth would be extraordinary for almost any business, let alone a company founded just five years ago.

Yet the quarterly figures tell a more complicated story.

Revenue increased 47% from the second quarter, down sharply from sequential growth of 144% in Q2 and 132% in Q1. The company is still growing at an exceptional pace, but the percentage growth rate is beginning to moderate.

Anthropic reported a third-quarter net loss of $23.29 billion, bringing its nine-month loss to approximately $104 billion, compared with $25.1 billion during the same period in 2025, CNBC reported.

The headline loss requires context. Much of it stems from noncash accounting adjustments involving convertible notes and derivative liabilities whose values changed as Anthropic’s valuation increased. Those charges do not represent an equivalent amount of cash spent operating the business.

Operating results offer another perspective. According to Reuters, Anthropic swung from $974 million in operating income in the second quarter to a $567 million operating loss in Q3, underscoring the costs of serving growing demand for its AI models.

Anthropic’s $895 billion infrastructure bet puts its IPO under scrutiny

Perhaps the most consequential disclosure has little to do with revenue.

Anthropic revealed approximately $895.4 billion in aggregate spending commitments under purchase agreements and leases, nearly all tied to computing capacity and infrastructure.

These are commitments spread over multiple years, not money the company has already spent. Still, their scale raises questions about how much revenue Anthropic must generate to support its long-term obligations.

The company reported that compute and infrastructure expenses increased by $14.4 billion during the first nine months of 2026, a 329% increase from a year earlier.

“As our compute and infrastructure capacity grows, the associated compute and infrastructure expenses have increased,” Anthropic said in the filing.

The disclosures build on concerns WIRED raised last week. The publication reported that Anthropic’s initial IPO prospectus left out several important financial figures, including third-quarter results, making it difficult for prospective investors to assess the company’s full financial position.

WIRED also highlighted the enormous infrastructure obligations already outlined in the original filing. Monday’s amendment provides a clearer accounting of those commitments.

Anthropic depends heavily on infrastructure providers, including Amazon and Google, to train and run its Claude models. Its reliance on outside computing capacity leaves the company exposed to rising costs, construction delays, and financial pressures across the data center industry.

Those risks arrive at a difficult moment for AI investors. Wall Street has grown increasingly concerned about the billions technology companies are spending on infrastructure, particularly as higher borrowing costs threaten the economics of debt-financed data center projects.

The upcoming offering could become one of the largest IPOs in history. Reuters reported that some investors have valued Anthropic at roughly $1.5 trillion, down from earlier estimates approaching $2 trillion.

The company’s prospectus devotes more than 90 pages to risks, covering everything from AI safety and government regulation to its unusually demanding infrastructure requirements.

For prospective shareholders, the question is no longer whether Anthropic can generate enormous revenue. The latest filing provides substantial evidence that it can.

The bigger question is whether that revenue can grow fast enough, and profitably enough, to justify the hundreds of billions of dollars committed to keeping Claude running.
