Anthropic's planned stock market debut reveals five key facts

Artificial intelligence (AI) company Anthropic has released a 335-page document ahead of its expected stock market debut in the United States. The document gives details about the company's finances, major customers, business risks and expectations for AI technology, the BBC reports.

The document filed by the company behind the Claude chatbot explains the challenges of building advanced AI. It also argues that this technology could bring major benefits to society.

Anthropic also described some risks it believes AI could pose, including the possibility that it could kill people. The document discusses these risks alongside the technology's many possible benefits.

Here are five key points from the filing.

AI poses risks to humanity

Anthropic warns that advanced AI systems could cause disasters or threaten humanity's survival if they are developed or used without proper safety measures, oversight and security.

The company also revealed that a hacking group it believes was backed by China used Claude to break into several organisations. These included technology companies, financial institutions, chemical manufacturers and government agencies, the BBC reports.

Anthropic said its success depends on its ability to keep developing and using advanced AI models. Getting enough computer chips, data centres and other equipment needed to build and run these models is one of the main risks to its growth.

The company is losing money despite rapid growth

Anthropic has not yet announced the share price it plans to set for its stock market debut. Many expect the company to be valued at $2 trillion or more. This could make it the biggest stock market listing in history.

However, the company's financial results will play a major role in deciding its value.

The filing shows that Anthropic recorded losses of $80.7 billion in the first half of this year. That was twice its total losses for all of 2025. During those six months, the company earned $16.2 billion in revenue.

Troy Hooper, co-head of equity capital markets at Mergermarket, called the company's revenue growth "exceptional". However, he said investors were becoming less willing to accept poor financial results in return for promises of profits in the future.

Hooper also said accounting costs linked to certain investments made it harder to judge how profitable Anthropic's main business really was and how much cash it was generating.

Anthropic has large cash reserves, but its costs are rising

Despite its losses, Anthropic reported $131.6 billion in cash and working capital, according to figures cited in the BBC report.

However, the company is facing rising costs as competition grows for skilled workers and computing power.

The filing also points to large costs for leasing data centres. Hooper expects these costs to rise as the company expands. He warned that even a large amount of cash might not be enough to support its growth forever.

Investors, he said, "will be paying for future dominance, not present-day economics".

A small number of customers account for much of its business

Anthropic depends heavily on a fairly small number of major customers.

The company said 250 business customers each paid it at least $10 million over the past year. Just five customers accounted for one-quarter of its business.

Michael Monaghan, a portfolio manager at Founder ETF, noted that many of Anthropic's biggest customers do not have long-term contracts. This means the company could lose a large amount of business if those customers leave.

Anthropic's ties to Google and Amazon could also create conflicts. Both companies have invested in Anthropic and compete with it in the AI market.

Even so, Anthropic said its number of business customers had grown from about 1,500 last year to nearly 12,000 this year.

Its strategy includes offering Claude tools for free and trying to turn free users into paying customers. The company claims this approach has helped it gain business customers faster than any other technology in history.

Anthropic expects AI to bring major benefits

Alongside its warnings about AI risks, Anthropic's filing explains why it believes advanced AI could bring "extraordinary" benefits.

The company says its mission is to develop and maintain advanced AI responsibly so that it benefits humanity over the long term.

Possible uses include creating treatments tailored to each person, detecting diseases more effectively, providing personalised education and making financial and legal advice easier to access.

Anthropic also expects AI to speed up scientific research, improve electricity grids and battery design, and help developing countries gain access to more advanced technology.

"Ultimately, we believe frontier AI will help drive global economic growth," the company said.
