American AI billionaire Dario Amodei's Anthropic posts $16.3 billion first-half revenue

Anthropic PBC, the artificial intelligence company run by American billionaire Dario Amodei, generated $16.3 billion in revenue in the first six months of 2026, up from $1.1 billion a year earlier, according to a draft of the prospectus for its planned initial public offering.

The San Francisco-based maker of the Claude chatbot posted a net loss of $80.7 billion for the period, compared with $13 billion a year earlier. About $72 billion of the loss came from noncash accounting charges tied to convertible notes and other financing instruments, rather than from day-to-day operations.

The draft filing also shows that Amodei, Anthropic's chief executive officer, and his sister Daniela Amodei, its president, were each paid a base salary of about $655,000 in 2025. Most of their compensation came in stock. Dario Amodei's total pay for the year was about $18 million and his sister's about $16.4 million.

Both of their salaries were raised to $1.4 million in July, and the board granted them restricted stock units this year, some of which vest only if the company goes public.

A pledge to give away 80%

Anthropic's co-founders have pledged to dedicate 80% of their personal Anthropic equity to charitable causes, a commitment set out in the IPO filing. The company does not disclose in the draft how much of Anthropic the founders own.

Dario and Daniela Amodei are among Anthropic's seven co-founders, who left OpenAI to start the company in 2021. Six of them, including the Amodei siblings, are each worth an estimated $15.5 billion.

Anthropic said on Sunday that it plans to place an initial 5% of its shares in a new Anthropic Public Benefit Fund, subject to shareholder approval. The fund could make large gifts to established nonprofits or direct payments to groups affected by AI, including workers. The company said none of the fund's equity will be used for lobbying or political donations. With the founders' pledge, an employee share-donation program and the new fund, Anthropic says about 20% of its shares will be set aside for public-benefit purposes.

Spending commitments and the listing

The draft prospectus shows the scale of Anthropic's bet on computing power. The company spent about $9 billion on computing capacity and infrastructure in the first half, more than the $7.3 billion it spent in all of 2025. It has signed about $450 billion of cloud computing commitments over the next decade, including $111 billion with Google Cloud, $110 billion with Amazon Web Services and $31 billion with Microsoft.

Amazon.com Inc. and Alphabet Inc.'s Google are Anthropic's largest outside investors. About 20% of first-half revenue came from two customers, and the company expects a small number of clients to keep accounting for a large share of its sales.

Growth picked up after June. Anthropic has told investors that revenue reached $16.8 billion in the third quarter, up from $11.5 billion in the second, and that it was profitable on an adjusted basis.

Anthropic submitted its draft registration to the U.S. Securities and Exchange Commission confidentially on June 1 and could file it publicly as soon as Friday. It has picked Nasdaq for the listing and is aiming to start marketing the shares to investors in the week of Nov. 9, though the timetable could still change. The offering could raise as much as $100 billion, which would make it larger than SpaceX's June listing, the biggest IPO on record.

Wall Street had expected a valuation of about $2 trillion. Some investors are now weighing a figure closer to $1.5 trillion after the latest disclosures. Anthropic raised $65 billion at a $965 billion valuation in May.
