Anthropic Revenue Climbs 45% to $16.8bn as IPO Draws Near

The Claude developer told investors it turned an adjusted profit for a second straight quarter, giving a nervous AI market its first hard look at a listing pitched near $2 trillion.

Key Takeaways

• Third-quarter revenue reached $16.8 billion, up from $11.6 billion and $4.7 billion, according to investor-day attendees. A single quarter now exceeds Anthropic’s 2025 revenue threefold.
• Anthropic reported adjusted profit and $1.70 of revenue per compute dollar, but that claim sits against at least $518 billion in long-term commitments to cloud and infrastructure suppliers.
• The figures emerged after a session in which the Nasdaq fell 1.9% on hot inflation data, leaving a public filing due before a November roadshow to deliver the market’s real verdict.

The Numbers Behind the Pitch

Anthropic built its reputation on caution, but on Wednesday it made its public-market case with arithmetic. At an investor day inside its San Francisco headquarters, Chief Executive Dario Amodei and Chief Financial Officer Krishna Rao told prospective shareholders that third-quarter revenue had reached $16.8 billion, according to people who attended. That was 45% more than the $11.6 billion booked in the second quarter and more than three times the $4.7 billion recorded in the first. The company also said it had been profitable on an adjusted basis, the second consecutive quarter on that measure, according to Bloomberg. Anthropic generated roughly $4.6 billion in all of 2025. A single quarter now exceeds that full year more than three times over.

Those numbers come with a caveat that sophisticated investors will not overlook. They are unaudited, they were presented to a closed room, and Anthropic has not published them. The company confidentially submitted a draft Form S-1 to the Securities and Exchange Commission on June 1 and has yet to file publicly, so no figure discussed this week can be checked against a document on EDGAR. Accounts already differ at the edges. Bloomberg places second-quarter revenue at $11.5 billion and first-quarter revenue near $4.8 billion, implying sequential growth of about 46%. The variance is a matter of rounding rather than substance. Even so, until a prospectus appears, investors are pricing reported figures, not disclosed ones.

A Slower Rate on a Far Larger Base

Read in isolation, the growth rate invites a cautious interpretation. Revenue rose roughly two and a half times between the first and second quarters, then 45% between the second and third. Some coverage has cast that deceleration as poorly timed for a company seeking a record valuation. The absolute figures tell a sturdier story. The $5.2 billion Anthropic added in the third quarter alone is larger than its entire revenue for 2025. Annualized, the quarter implies a pace of about $67 billion. That is in line with Bloomberg’s August report that the run rate had passed $65 billion by the end of July, and well above the $47 billion figure Anthropic itself disclosed alongside its Series H in May.

The harder test lies in the exit rate. Analysts who met executives this week estimate that annualized revenue could reach $110 billion by year-end, according to Reuters. Getting there would require monthly revenue of roughly $9 billion by December, compared with a third-quarter average of about $5.6 billion. That is a plausible extension of the first half and a steep climb from the third quarter. It matters because a valuation near $2 trillion has reportedly been anchored to forward revenue, with bankers discussing projected 2028 sales of $190 billion to $200 billion. The fourth quarter will be read as evidence of the slope on which the entire valuation rests.

The Price of Compute

Of everything presented on Wednesday, the profitability claim carries the most weight and the most careful wording. Anthropic told investors it was cash-flow positive and earned $1.70 in revenue for every dollar spent on computing power in the quarter, the Financial Times reported. That ratio addresses the question that has shadowed every frontier AI developer: whether inference revenue can outrun the cost of the chips required to serve it. The improvement from a year earlier is striking. Reuters reported last month that Anthropic’s 2025 operating loss exceeded $8 billion, excluding writedowns of liabilities tied largely to earlier fundraising. The company has not disclosed what it excludes to reach adjusted profit, and the prospectus will have to reconcile those measures with generally accepted accounting principles.

The obligations behind that ratio reach well beyond a single quarter. Anthropic has committed at least $518 billion over roughly a decade to cloud services, computing and infrastructure, according to Reuters. Those commitments are deliberately spread across suppliers:

• Amazon Web Services holds a reported commitment of more than $100 billion over ten years, including up to five gigawatts of capacity.
• Google agreed in October 2025 to supply up to one million of its Tensor Processing Units.
• Broadcom Chief Executive Hock Tan has said Anthropic will become his company’s largest custom-chip customer in fiscal 2027.

Anthropic is now a long-dated buyer of computing capacity on a scale few companies have attempted. Its margins will rise or fall with its ability to keep demand level with supply.

Products, Partners and Policy Risk

Enterprise and developer demand remains the engine beneath these numbers, and the company’s recent releases have been designed to feed it. Anthropic introduced Claude Haiku 5.5 on October 7, a lower-cost small model built for high-volume workloads, and cut cache pricing for Sonnet 5.5 in the same release. It shipped Claude Fable 5.1 and Claude Mythos 5.1 on September 1. On October 6 it broadened its Cyber Verification Program, giving vetted security professionals access to more advanced capabilities, and on October 1 it announced that Barclays was scaling Claude across its operations and client service. On the day of the investor meeting itself, it opened an office in Singapore and signed a memorandum of understanding with the government there.

Policy exposure is the variable no spreadsheet captures cleanly. In June, Anthropic suspended access to Claude Fable 5 and Claude Mythos 5 for nearly three weeks to comply with US Department of Commerce export controls, restoring service on July 1 once the controls were lifted. Bloomberg reported this month that prospective IPO investors are struggling to price the risks attached to advanced model capabilities. JPMorgan Chase Chief Executive Jamie Dimon has said Mythos raised cyber risk tenfold. For a company whose most capable products already sit behind access controls, these concerns are operational rather than theoretical. The prospectus will need to describe that exposure in terms public investors can price.

Market Response and the Road to Listing

The figures reached investors after the closing bell, at the end of a difficult session. Hotter-than-expected September inflation data revived expectations of tighter Federal Reserve policy. The Nasdaq Composite fell about 1.9% and the S&P 500 declined 1.1%. AI infrastructure stocks took the heaviest losses, with Oracle down roughly 9% and CoreWeave more than 15% amid renewed concern over debt-financed data center construction. Amazon and Alphabet, Anthropic’s two largest corporate backers, each fell about 1.7%. Two days earlier, Hock Tan had remarked that many AI investors behave like gamblers. Anthropic’s numbers therefore land in a market that wants evidence on costs before it pays for growth, and the adjusted profit is aimed squarely at that demand.

For Amazon and Alphabet, the consequences already show up in their income statements. Amazon’s second-quarter results included a $53.4 billion non-operating pre-tax gain arising primarily from its Anthropic investments. Alphabet, which reports third-quarter earnings on October 28, carries its stake at a reported value of about $124 billion. Bloomberg reported that formal marketing could begin as soon as the week of November 9, with trading before Thanksgiving. Nasdaq is the reported venue, with Morgan Stanley, Goldman Sachs and JPMorgan among the banks. At $2 trillion, Anthropic would be valued at roughly 30 times its annualized third-quarter revenue and about twice its $965 billion Series H mark. SEC procedures require the registration statement to be public at least 15 days before the roadshow. That document, not Wednesday’s presentation, will decide whether the price holds.
