Artificial intelligence company Anthropic has revealed extraordinary revenue growth alongside enormous spending commitments as it prepares for a potential stock market debut that could value the business at up to US$2 trillion.

The company behind the Claude AI chatbot filed its initial public offering (IPO) prospectus with the US Securities and Exchange Commission on October 26, providing a detailed look at the finances of one of OpenAI’s biggest competitors.

According to the filing, Anthropic generated US$16.3 billion in revenue during the first six months of 2026, compared with approximately US$1.2 billion during the same period last year.

The dramatic increase follows a strong 2025, when annual revenue reportedly climbed to US$4.6 billion from just US$386 million in 2024.

However, the company’s rapid expansion has also come with substantial financial costs.

Anthropic reported a net loss of US$80.7 billion for the first half of 2026, although US$72.4 billion was attributed to non-cash accounting adjustments linked to financial instruments affected by the company’s rising valuation.

Its underlying operating performance showed considerable improvement, with losses narrowing to US$693 million during the six-month period, compared with US$2.1 billion a year earlier.

The company also reported an operating profit of US$974 million during the second quarter, suggesting its rapidly expanding revenue is beginning to offset the enormous cost of developing and operating advanced AI systems.

Despite those improvements, Anthropic is preparing to spend heavily as competition in the artificial intelligence industry intensifies.

Its IPO prospectus outlines hundreds of billions of dollars in computing and infrastructure commitments, including spending on data centres, advanced processors and cloud computing services.

These investments are essential to developing increasingly powerful AI models and supporting growing demand from businesses using the company’s technology.

Enterprise customers have become a major driver of Anthropic’s growth, particularly through its Claude AI models and Claude Code software development platform.

By the end of September, more than 11,900 customers were spending at least US$100,000 annually on Anthropic products.

Of those, more than 1,900 customers were spending over US$1 million a year, while approximately 250 were paying at least US$10 million annually.

The figures highlight how quickly businesses are incorporating AI tools into their operations, with Anthropic increasingly targeting large corporate customers willing to spend heavily on automation and software development.

However, the filing also reveals several risks facing the company.

Anthropic relies heavily on major technology companies, including Amazon, Google and Microsoft, for cloud infrastructure and access to customers.

Those relationships are complicated by the fact that the same companies are also developing competing artificial intelligence products.

Customer concentration presents another challenge, with Anthropic’s five largest clients accounting for approximately a quarter of its revenue during the first nine months of 2026.

The company is reportedly considering an IPO valuation of between US$1.5 trillion and US$2 trillion, although a final share price has yet to be determined.

Anthropic plans to list on the Nasdaq exchange under the ticker symbol ANT, potentially creating one of the largest technology listings in stock market history.

The move comes as rival OpenAI also explores a possible public offering, with both companies seeking access to additional capital to fund increasingly expensive AI development.

For Anthropic, a successful IPO could provide the financial resources needed to expand its infrastructure and strengthen its position in the rapidly growing artificial intelligence market.

However, its financial disclosures also highlight the central challenge facing the AI industry: turning extraordinary revenue growth into sustainable profits while continuing to invest billions in the technology needed to remain competitive.
