Anthropic's blockbuster share listing - 5 surprising things we now know

Artificial intelligence (AI) company Anthropic has released the required documents ahead of its long-awaited launch on the US stock market.

The 335-page document gives new details about how the company behind the Claude chatbot makes money, what it spends money on and who controls it.

Anthropic also explained the risks of its technology, including the possibility that it could take human lives. The company described these risks alongside the many benefits it believes the technology could bring.

Here are five important points from the document.

1. The risk of disaster is part of the job

Every company that sells shares to the public must explain to possible investors what could go wrong.

Anthropic's section on risks was unusual because it also explained how the AI technology it is developing could threaten all of humanity.

Anthropic said: "Sufficiently advanced AI systems could, if not developed, deployed, and operated with appropriate safeguards, oversight, and security measures, pose catastrophic or existential risks to humanity."

The company also said that less than a year ago, a hacking group that Anthropic believed was backed by China used Claude in a way that helped it break into several organisations. These included large technology companies, financial institutions, chemical manufacturers and government agencies.

But Anthropic said its success depends on its ability to keep developing, improving and releasing the most advanced, capable and useful AI models.

One major risk is whether Anthropic can get the equipment and facilities it needs, including computer chips and data centres. These are needed to build, train and run the AI models behind its technology.

2. The company is losing huge amounts of money

Anthropic has not yet announced the price it plans to set for its shares when it joins the stock market.

Many people expect the company to be valued at $2 trillion or more when it launches. That would make it the biggest stock market listing in history. However, its financial results will have a major effect on its final value.

Anthropic lost $80.7bn (£60bn) in the first half of this year. That was twice as much as it lost during all of 2025.

The company's total revenue was $16.2bn during the six-month period. Its income is growing quickly, but it still has a long way to go before it earns enough to cover its costs.

3. But it has plenty of cash available

Although Anthropic is losing money, it has a very large amount of cash available.

It has $131.6bn in cash, almost all of which it counts as "working capital". This means the money is available to pay for its everyday business activities.

Anthropic currently has more cash available than Meta and Google combined.

However, its costs could rise as it competes with other major AI companies for skilled workers and computing power. Renting data centres alone is costing the company $321.4bn so far this year.

4. Anthropic depends on a small number of big customers

Anthropic believes there are many ways it can sell its technology to customers.

A large part of its current business comes from just 250 major business customers. The company says each of these customers has paid it at least $10mn over the past year.

An even smaller group, made up of just five business customers, accounts for a quarter of its current business. This means Anthropic depends on a small number of paying customers to help its business grow.

Anthropic said the number of business customers it serves has grown quickly, rising from about 1,500 last year to almost 12,000 this year.

One part of its growth plan is to let people use Claude tools for free at first, then try to turn them into paying customers over time.

Anthropic claimed this plan has helped Claude achieve "the fastest enterprise adoption of any technology in history".

The company also said the number of users can go up and down. For example, people use AI tools less around Christmas. In January, customer spending fell by 20%, which Anthropic said was part of a seasonal pattern in its business.

5. AI could bring 'extraordinary' benefits to the world

Although Anthropic has warned about the risks of AI, it repeated its belief that AI could also do an extraordinary amount of good.

The company said: "Achieving our mission means the world gains the enormous benefits of frontier AI while mitigating the most significant risks."

Anthropic describes its mission as "The responsible development and maintenance of advanced AI for the long-term benefit of humanity."

It also said: "We do not pursue projects based on commercial opportunity or research novelty alone; our efforts must advance our mission."

Possible benefits include better healthcare, such as treatments designed for individual patients and better ways to detect diseases. AI could also help provide education and legal advice suited to each person, and make power grids and batteries work more efficiently.

Scientific progress that might normally take decades could happen in just a few years. This could speed up the discovery of new medicines, the detection of diseases and the delivery of treatments designed for individual patients.

Anthropic said AI could also provide education tailored to each person and expert financial and legal advice. It could help make power grids and batteries more efficient and reliable, and help countries in the developing world build stronger technology skills and systems.

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