Anthropic seeks an IPO despite a massive reported loss

Anthropic wants to go public with figures that seem difficult to reconcile. In the first six months of 2026, the company behind Claude AI generated $16.3 billion in revenue, yet reported a net loss of $80.7 billion. On 26 October, Anthropic filed documents with the US securities regulator as it prepared for a stock market listing. The move begins a new phase for one of the biggest names in artificial intelligence.

The possible valuation makes the news even more striking. Media reports have cited figures between $1.5 trillion and $2 trillion. Those are not confirmed market values. The final offer price and number of shares have not been announced. What do the filings reveal, why does Anthropic want to list, and what could it mean for investors?

Anthropic wants to turn Claude into a publicly traded company

Anthropic is the AI company behind Claude, a chatbot and a family of AI models used by people and businesses to write, analyse information and carry out programming tasks. Former OpenAI employees founded the company in 2021. It presents itself as a company focused on the safe development of artificial intelligence.

On 26 October 2026, Anthropic announced that it had filed a registration statement, known as Form S 1, with the US Securities and Exchange Commission, or SEC. This is an important step toward an IPO. The company intends to list its shares on the Nasdaq Global Select Market under the proposed ticker symbol ANT.

The registration is not yet effective, and the shares cannot be sold until the process allows it. Anthropic has not announced the final offer price or the size of the offering. The IPO is being prepared, not completed.

What does that mean? An IPO is the first public sale of a company’s shares. Investors can become shareholders, and the shares may then trade on a stock exchange. Money raised by issuing new shares goes to the company. If existing shareholders sell their shares, the proceeds go to them.

Revenue grew from $41 million to $16.3 billion

Anthropic’s growth has been exceptionally fast. Its registration statement reports revenue of about $41 million in 2023, $386 million in 2024 and $4.6 billion in 2025.

The company then reported $16.3 billion in revenue for the six months ending in June 2026. That was about 1,300% more than in the same period of 2025.

These figures show that businesses and developers are paying more for access to Claude and the models behind it. Anthropic earns money through business subscriptions, API access and products such as Claude Code.

However, the company itself warns that growth may not continue at the same pace. The market for advanced AI is changing quickly. Competitors can improve their models, lower prices or bundle AI into existing software. Past revenue growth is not a promise about future results.

The $80.7 billion loss needs context

A net loss of $80.7 billion sounds as though Anthropic burned tens of billions of dollars in cash in six months. The figure alone does not show that. According to Sky News’ report on the financial disclosures, $72.4 billion of the loss came from an accounting charge associated with the rising valuation of the company.

An accounting charge is not automatically a cash payment. The valuation of certain share based compensation can change and affect reported results. That is why investors need to distinguish between net loss, operating results and money actually received or spent.

Sky News reported an operating loss of $693 million. Anthropic also spent nearly $9 billion on computing power and infrastructure. Those costs are real. Advanced AI requires specialised chips, data centres, electricity and the capacity to train and run models.

Watch out: A large net loss does not automatically mean that the same amount of cash has left a company. For AI businesses, also examine operating results, infrastructure investment, cash flow and how share based compensation is recorded.

The distinction matters to investors. Revenue is growing rapidly, and the operating loss is far smaller than the net loss. But Anthropic has not yet demonstrated an annual net profit. It still needs to show that revenue can cover development, infrastructure and expansion costs.

A $2 trillion valuation is not a confirmed price

Reports about the proposed IPO have cited a valuation between $1.5 trillion and $2 trillion. For comparison, Anthropic said its May 2026 funding round valued the company at $965 billion after the investment.

A valuation is the amount investors assign to the whole company. It is different from the amount of money Anthropic raises in the IPO. The company has not disclosed how many shares it plans to offer, the price per share or the final proceeds.

A company’s value depends on more than today’s revenue. Investors also pay for expectations about future growth and profits. The higher the valuation, the more future success may already be reflected in the price.

Here is a simple example. Suppose you buy €1,000 worth of shares once they become available to trade. If the share price then falls by 30%, your holding is worth €700. You have lost €300, excluding transaction costs and currency effects. If the share price rises by 30%, the holding would instead be worth €1,300. These are calculations, not forecasts for Anthropic.

The IPO could fund expansion and give shareholders more options

A public listing can give a company access to a larger pool of investors. Anthropic could use the proceeds to secure more computing power, develop new models, enter international markets and potentially acquire other businesses. A listing can also make it easier for existing shareholders to sell their stakes later, depending on the terms.

Anthropic needs resources to compete with OpenAI and major technology companies developing their own AI models. It relies on infrastructure partners including Amazon, Google and Microsoft. These relationships provide access to capacity, but they also create dependencies.

The IPO also brings greater visibility into the company’s finances. Public companies must publish regular results and disclose important risks to investors. That provides more information, but it does not prevent disappointing results.

Major customers can be both an advantage and a risk

Anthropic sells its technology to businesses that integrate Claude into their daily operations. That can generate recurring revenue. But the registration statement also shows that a relatively small group of customers accounts for a significant share of sales.

According to the filing, the five largest customers represented about 25% of revenue during the nine months ending in September 2026. No single customer accounted for more than 10% on its own during that period. Even so, a spending reduction by several large customers could affect growth.

Another concern is how revenue reaches customers through cloud platforms. In the first half of 2026, about 48% of revenue came through cloud provider marketplaces. These partners help Anthropic reach customers, but they can also affect customer access, costs and commercial terms.

Competition remains a risk as well. Customers may switch to other AI models, build their own systems or reduce AI usage if the costs outweigh the benefits. Anthropic itself lists uncertainty around demand, costs, safety and its ability to sustain growth.

The biggest question is whether AI can deliver profits

The figures show that demand for Claude is growing quickly. They do not yet prove that the company will be profitable over the long term. AI companies must invest heavily before they know how durable demand will be or how much customers will continue to pay.

Investors therefore need to look beyond revenue growth or a possible valuation. Operating profit, cash flow, computing costs, customer concentration and the final share price all matter. A strong company can still be a disappointing investment if its price is too high for the results it eventually delivers.

The US SEC warns that IPO investing can be risky. The final market price can differ substantially from the offer price. A share price can also move sharply after the first days of trading. A popular IPO is not proof that a stock is cheap.

Questions to ask before assessing an IPO

• How many shares will be offered, and what is the final price?
• How much of the proceeds will go to the company and how much to existing shareholders?
• What are the operating loss, investment needs and cash outflows?
• How dependent is the company on a few customers and infrastructure partners?
• What level of revenue and profit would justify the final valuation?

Anthropic’s filing is a first step, not proof that the IPO will succeed. The final terms and financial results will matter. This article is for educational purposes and is not financial advice.
