Anthropic (ANTH.PVT) has submitted its S-1 investment prospectus to the Securities and Exchange Commission, revealing key financial metrics in advance of its initial public offering. The company, which will operate under the ticker symbol ANT, reported $16.3 billion in revenue for the six months ending in June, surpassing its total revenue of $4.6 billion for the entire year of 2025. However, Anthropic incurred $9 billion in AI infrastructure expenses during the same period, exceeding the $7.3 billion spent throughout 2025.

Approximately 20% of Anthropic's revenue came from just two customers, with the remainder from a limited number of clients. Despite the revenue increase, the S-1 indicates a net loss of $80.7 billion through June, primarily attributed to accounting charges, following a loss of $42 billion in 2025.
Additionally, the company plans substantial investments of over $430 billion in long-term cloud computing agreements with major stakeholders like Amazon and Google, which are also significant investors in Anthropic. Including other cancellable and smaller contracts, total commitments could reach as high as $637 billion.
Anthropic’s upcoming market debut will be a benchmark for investors’ interest in the public listings of companies with substantial valuations. SpaceX (SPCX) recently went public on June 12 at $150 per share, finishing the day up by 20%.
Led by CEO Dario Amodei, co-founder alongside his sister Daniela, who serves as president, Anthropic has made inroads in the enterprise sector, notably with its Claude chatbot and AI coding tool, Claude Code. The S-1 also underscores the company's concerns about the unpredictable capabilities of its AI models, which could lead to significant real-world risks. Amodei recently advocated for a slowdown in the development of advanced AI models, citing worries that they might outstrip human control. This call, along with comments from AI researchers, has sparked discussions about the potential dangers of AI, including fears of catastrophic misuse, though experts argue that the primary risks are tied to cybersecurity and misuse of technology.
