Anthropic IPO spotlights soaring revenue, huge losses and AI safety risks

Anthropic has unveiled its US initial public offering (IPO) filing, revealing explosive revenue growth, mounting financial losses and significant risks associated with developing increasingly powerful artificial intelligence (AI) models.

The filing, released on Monday, October 26, offers a glimpse into the financial performance of the company behind the Claude AI models as it prepares for a potential stock market debut. The offering is expected to provide a crucial test of investor appetite for leading AI companies amid growing concerns about the sustainability of the sector’s massive investments.

Anthropic reported revenue of approximately $16.3 billion in the first half of 2026. However, its net loss widened sharply to $80.7 billion, largely reflecting an increase in the fair value of bonds convertible into company shares. Revenue in the three months ended June 30 surged 1,368 per cent from a year earlier.

The company’s rapid expansion comes as technology firms pour billions of dollars into AI development, data centres, computing infrastructure and advanced chips. While the spending has fuelled investor enthusiasm, concerns are mounting over whether future earnings will justify the enormous investments and valuations.

Anthropic IPO emerges as key test for AI valuations

Anthropic’s proposed listing could establish a benchmark for how investors value leading AI developers, including its rival OpenAI.

Some current and prospective investors were valuing Anthropic at around $1.5 trillion, down from approximately $2 trillion a week earlier, Reuters reported, following the disclosure of financial details at a recent investor event.

More from Business

The company was valued at $965 billion in a funding round in May. Amazon and Google have been among its key strategic partners, providing billions of dollars in investment and the cloud infrastructure required to train and operate its AI models.

Anthropic said computing and infrastructure expenses would continue to increase in absolute terms and remain its largest operating expense for the foreseeable future.

The company also warned that its revenue and accounts receivable were concentrated among a limited number of customers and distribution channels, highlighting potential vulnerabilities in its business model.

The IPO comes amid a volatile market environment, with investors reassessing the scale of AI-related investments and the debt being accumulated to finance infrastructure expansion.

AI safety risks feature prominently in filing

Beyond financial performance, Anthropic’s prospectus highlights the potential risks posed by advanced AI systems.

The company warned that its business depended heavily on its ability to develop increasingly capable AI models, adding that failure to maintain technological leadership could adversely affect its prospects.

Anthropic’s own research has raised concerns about the behaviour of advanced AI systems, which have demonstrated potentially harmful actions in controlled tests, including code sabotage, assistance with fraud and information manipulation.

The prospectus also warned that its models could exhibit behaviours resembling self-preservation, including attempts to resist shutdown, conceal or manipulate information, and engage in behaviour resembling blackmail.

These concerns come as AI developers face growing scrutiny over their ability to keep increasingly powerful systems under control while deploying them commercially.

Chief Executive Dario Amodei has called on the global AI community to slow the release of new capabilities to address safety risks. At the same time, Anthropic is competing with OpenAI to develop more advanced models and expand its commercial reach.

Anthropic and OpenAI intensify IPO race

Anthropic, founded in 2021 by a team of researchers, is locked in an intense competition with OpenAI, the company behind ChatGPT.

OpenAI confidentially filed for an IPO in June and is expected to list by early 2027. Its chief executive, Sam Altman, said in September that the company would not go public this year, citing AI safety concerns.

Anthropic’s filing did not disclose the proposed price range or the number of shares it intends to sell. The company is expected to trade on the Nasdaq under the ticker symbol ANT once the IPO is completed.

Goldman Sachs and Morgan Stanley are leading the syndicate of Wall Street banks underwriting the offering.

The proposed listing follows SpaceX’s record-breaking IPO in June, when Elon Musk’s company priced a $75 billion offering at a valuation of $1.75 trillion.

For Anthropic, the public-market debut will test whether investors are willing to back the extraordinary growth potential of AI while accepting the steep costs, uncertain returns and safety challenges associated with developing the technology.
