❯ Anthropic files for IPO with $16.3 billion in first-half revenue and over $600 billion in compute commitments
Claude heads for public marketsAnthropic says it has publicly filed for an IPO and plans to list on Nasdaq under the symbol ANT. The number of shares and offering price have not been set. The Wall Street Journal reported, citing people familiar with the matter, that Anthropic is targeting the week of November 16 and could raise about $100 billion at a valuation of $1.5 trillion to $2 trillion. Those are reported targets, not final terms.
Six months beat last yearReuters reports that Anthropic’s revenue grew from roughly $41 million in 2023 to $386 million in 2024 and $4.59 billion in 2025. It reached $16.29 billion in the first half of 2026, about 14 times the $1.16 billion recorded a year earlier and far more than the whole of 2025. The filing provides the first systematic public view of the model developer’s business at this scale.
How Anthropic earns moneyThe company’s core technology is the Claude model family, with tiers including Fable, Opus, Sonnet and Haiku. Individuals can chat and work with documents through Claude or pay for Pro and Max subscriptions. Businesses and developers can integrate Claude into their own software through an API and pay according to the tokens processed. Reuters says consumption-based business use accounts for most revenue.
From models to applicationsAnthropic also builds products around its models, including Claude Code for reading, writing and modifying software, and Claude Cowork for enterprise tasks. Its early focus on coding created opportunities for sustained use and a route to sell other Claude services to companies. TechCrunch reported that more than half of customers spending at least $100,000 use both Claude Platform and at least one first-party app.
Large customers form tiersTechCrunch’s figures, relayed by Techmeme, show that as of September 30 Anthropic had over 11,900 customers who generated at least $100,000 in the preceding 12 months. More than 1,900 generated at least $1 million and roughly 250 generated at least $10 million. These thresholds overlap and cannot be added together. They show Claude’s reach beyond individual users into enterprise systems and team workflows.
Understanding the $80.7 billion lossAnthropic reported a net loss of approximately $80.7 billion in the first half, including a large accounting adjustment connected to financing agreements. AP reports that the adjustment accounted for about $72.4 billion, so the net loss is not equivalent to cash spent on operations during the period. Reuters puts operating loss at $693 million, down from $2.14 billion a year earlier, as rapid revenue growth offset part of the increase in expenses.
Compute is the biggest expenseTraining models and answering user requests both require computing resources. Anthropic pays for cloud capacity, data center space, equipment leases and energy. Reuters says it has committed to more than $600 billion of spending with around eight partners over roughly a decade; some agreements are non-cancellable or require payment regardless of usage. The figure covers future years and is not the amount paid in the first half.
Owned equipment and leasesThe Hum’s analysis of media and filing materials reports $482 million of property and equipment purchases in the first half. As of June 30, signed leases that had not yet begun represented roughly $321.4 billion in future payments, some subject to conditions. Culpium has put forward a figure of about $782 billion, but its calculation is not publicly visible and The Hum questions whether it consists entirely of leases. These figures have different dates and scopes and cannot simply be added.
Who controls the companyFormer OpenAI researchers founded Anthropic in 2021, including siblings Dario and Daniela Amodei. Dario is CEO; Daniela is president and board chair. Reuters says Anthropic will remain a public benefit corporation after listing. Its seven co-founders will direct a single special Class F share carrying 50.1% of voting power on important shareholder matters, while an independent long-term benefit trust participates in board governance. The structure is intended to preserve the company’s approach to AI development as it raises capital.
Major backersGoogle and Amazon are both important financial backers and compute partners. The Wall Street Journal reports that venture firm Spark Capital invested nearly $800 million across six funding rounds. Spark partner Yasmin Razavi is the only venture capitalist on Anthropic’s board.
Why go publicGoogle and Amazon supply computing as well as funding. Cloud services and leases let Anthropic obtain capacity without building every data center itself, but they also create purchase and rental obligations over many years. An IPO would add a funding channel; continued conversion of Claude usage into revenue is central to understanding those commitments.
▮ SIGNALAnthropic has demonstrated enterprise demand for models and applications, while its expansion increasingly depends on securing compute and funding years in advance.
