Anthropic reported $17 billion in revenue for the three months ending Sept. 30, according to an amendment to its Form S-1 registration statement filed with the Securities and Exchange Commission on Monday, Nov. 2. The artificial intelligence company used the filing to update investors on its financial trajectory as it prepares for a proposed initial public offering.
Record Growth and Infrastructure Commitments
The amendment highlights a dramatic expansion in the company’s financial scale. Anthropic stated that its revenue grew 1,127% year over year during the quarter. This surge occurred alongside a significant increase in operational costs, with compute and infrastructure expenses rising 382% compared to the same period last year.
The company disclosed that as of Sept. 30, it had entered into purchase commitments and lease agreements totaling approximately $895.4 billion. Anthropic noted that almost all of this capital is dedicated to compute and infrastructure needs. This massive allocation underscores the heavy capital requirements associated with training and running large language models.

Anthropic also reiterated the market reception of its primary product, Claude. The company stated that since launching Claude in the first quarter of 2023, the technology has experienced the fastest enterprise adoption of any technology in history. This claim serves as a key metric for investors evaluating the company’s competitive position in the generative AI sector.
Global IPO Strategy and Market Context
While the SEC filing did not specify the valuation or size of the listing, multiple media reports indicate Anthropic is targeting a raise of $3.5 billion from investors in Japan. Reuters reported on Monday that the AI company plans to use the new funding for working capital, operating expenses, and capital expenditures.
Bloomberg reported on Sunday, Nov. 1, that this offering structure makes Japan one of only a few international markets where investors will have direct access to Anthropic’s U.S. IPO. Other designated markets include Australia, Canada, and select regions in Europe. This multi-jurisdictional approach aims to broaden the investor base beyond the United States.
The filing comes at a time of heightened scrutiny for the AI industry. Anthropic became the first frontier AI lab to seek a public listing, a move that many analysts view as a major test for the sector. Investors have grown increasingly wary of the heavy spending required to sustain AI development, especially as competition for market attention intensifies.

Competitor dynamics also play a role in the current market environment. Reports from late October indicated that rival OpenAI reduced its target for a current funding round from $30 billion to $20 billion. OpenAI is seeking to raise funds at a valuation of $1.25 trillion, down from a previous target of $1.4 trillion. Industry observers attributed this adjustment to a sell-off in AI-related shares and tepid interest from some large institutional investors.
Anthropic’s latest financial disclosure provides the first detailed look at the revenue scale of a major AI lab ahead of a public debut. The company’s ability to demonstrate rapid enterprise adoption while managing substantial infrastructure costs will likely influence investor sentiment as the IPO process moves forward.
