Anthropic has made its US initial public offering (IPO) filing public, offering investors a closer look at the rapid growth and financial challenges facing the company behind Claude AI. The October 26 disclosure highlights surging revenue, mounting infrastructure costs and risks that could shape the future of one of the AI industry's leading startups.
The planned listing could also provide an important benchmark for valuing other AI companies, including rival OpenAI, as investors question whether massive spending on the technology will deliver lasting returns.
Anthropic's revenue climbed to USD 16.29 billion in the first half of 2026, compared with USD 4.59 billion for the whole of 2025. The company's annual revenue had already increased sharply from USD 386 million in 2024, reflecting growing demand for its AI models and coding tools.
Businesses pay to use Claude based on consumption, while paid subscriptions provide another source of income. Anthropic has gained attention among developers and enterprise customers as competition intensifies across the AI market.
However, growth has come with substantial losses. The company reported an operating loss of USD 693 million in the first half of 2026, following an USD 8.06 billion operating loss in 2025.
Running advanced AI models requires enormous computing capacity, including data centers, specialised chips, electricity and cloud services. Anthropic's filing highlights the scale of these commitments.
The company has agreed to spend more than USD 500 billion with infrastructure partners over a decade. Its commitments include at least USD 110 billion with Amazon, USD 114.5 billion with Google and USD 44.9 billion with Microsoft for cloud computing.
Anthropic also reported a net loss of USD 80.7 billion for the first half of 2026. However, this figure was largely driven by a USD 72 billion accounting charge linked to the increased estimated value of convertible bonds, rather than equivalent cash spending on operations.
Amazon and Google are not just Anthropic's investors; they also supply computing infrastructure and help distribute its products. This overlap creates potential conflicts, particularly if the companies' commercial interests diverge.
Anthropic also faces competition from OpenAI, Google and other AI developers, all investing heavily in new models and infrastructure.

The filing also highlights risks involving advanced AI systems, including potential manipulation, fraud assistance and other harmful behaviour observed in controlled tests. Anthropic must balance its push for more capable models with its stated focus on AI safety. For investors, the IPO will test whether rapid growth can translate into sustainable returns while the costs and risks of AI development continue to rise.
