Anthropic’s reported draft S-1 shows 2025 revenue of nearly $4.6 billion alongside an $8.06 billion operating loss and heavy infrastructure spending. The filing also warns investors about potential harms from advanced AI; the timing and valuation of a public offering remain uncertain.
Anthropic has reportedly shared a draft S-1 filing with a small group of partners, laying out surging revenue, rising costs and warnings that its advanced AI systems could pose serious risks. The disclosures offer a rare view of the finances and investor risks behind one of the leading AI developers as it weighs a possible public offering.
Revenue rose twelvefold in 2025 to nearly $4.6 billion, Reuters reported. The company’s operating loss widened from $2.98 billion to $8.06 billion. Anthropic spent $7.33 billion on compute and infrastructure, about three times its spending the previous year and more than half of its operating costs.
The filing reportedly records a net loss of roughly $42 billion, but Reuters said about $34 billion of that reflects an accounting charge tied to the estimated value of financing that could later convert into shares. That charge does not represent cash spent to operate the business. The company also disclosed customer concentration: two customers accounted for nearly a quarter of 2025 revenue, and Anthropic warned that many large customers are not bound by long-term contracts.
Anthropic plans $518 billion in cloud, compute and infrastructure commitments over the coming years, according to the report. The Financial Times reported that second-quarter 2026 revenue reached $11.5 billion and that the company was on track for a second consecutive quarter of operating profit on an adjusted basis. Adjusted results exclude certain costs, so they do not mean the company reported overall operating profit.
The Cost of Scaling Anthropic
The figures show the financial trade-off facing a company trying to build and sell advanced AI models: rapid sales growth comes with substantial infrastructure bills. Compute spending and future commitments could weigh on finances even as demand expands. Customer concentration adds another exposure; losing or reducing business from a small number of large buyers could affect revenue.
The reported risk disclosures also matter to prospective investors and the wider public. Anthropic is presenting potential AI harms as a material business risk, alongside the financial uncertainties. Its warnings do not establish that such harms have occurred, but they signal that the company considers model behavior and safety relevant to evaluating its prospects.
A potential listing could give public-market investors a closer look at how AI companies account for financing, infrastructure commitments and adjusted profitability. Reuters reported that analysts expect the first AI company to list publicly to influence valuation benchmarks for rivals, including OpenAI. No valuation or offering terms have been confirmed.
A Filing Ahead of Possible Listing
An S-1 is the registration statement companies submit to the U.S. Securities and Exchange Commission before a public stock offering. The described document has not been presented here as a final public filing: according to the reports, Anthropic circulated it to a limited group of partners. The Financial Times and Reuters reviewed the prospectus, with The Decoder relaying their reporting.
The reported filing comes amid expectations that major AI developers may seek public-market financing. Reuters sources said Anthropic’s debut was unlikely before November, after the U.S. midterm elections. The Financial Times reported that backers considered a valuation above $2 trillion possible. That is an investor expectation, not a confirmed valuation or a company commitment.
The filing reportedly describes Anthropic’s view that AI could reshape the global economy more deeply than industrialization, electricity or the internet. That is the company’s assessment, not an independently established forecast. Its risk section, which the Financial Times said takes up nearly a third of the document, reportedly discusses possibilities including manipulation, blackmail and unpredictable behavior by increasingly advanced models.
““existential risks to humanity””
— Anthropic, as described in the reported prospectus
Offering Terms Remain Undisclosed
Anthropic has not publicly confirmed an IPO date or valuation in the source material. The reported S-1 was shared with a small group of partners, and the timing described by Reuters sources is not a formal schedule. It remains unclear whether or when the draft will become a public registration statement, what share sale the company might pursue, or what terms it would offer.
The reported second-quarter revenue and adjusted operating-profit outlook also do not establish full-year performance or sustained profitability. The filing’s risk scenarios describe potential outcomes, not predictions that every scenario will occur. The source material does not specify the duration or terms of the $518 billion commitments, nor how much of the spending could change as plans evolve.
Watch for a Public Filing
The next major milestone would be a public S-1 filing with the SEC, if Anthropic proceeds with an offering. That document would allow investors to examine the complete disclosures, including financial statements, risk factors and proposed terms. Reuters sources placed a possible debut no earlier than November, but the schedule could change.
Until then, investors and industry observers will be watching for updated revenue, spending and profitability figures, as well as clarity on customer commitments and infrastructure obligations. Any valuation discussed by backers should be treated as tentative unless Anthropic sets terms in a formal offering.
