Anthropic Reportedly Told Investors Q3 Revenue Hit $16.8B

Anthropic told prospective investors that third-quarter revenue stands at $16.8 billion as it prepares for a highly anticipated initial public offering reportedly slated for November, according to people familiar with the matter cited by CNBC. The Claude maker disclosed the figures at a meeting with potential investors, including institutional investors, CNBC previously reported—not in an audited SEC filing.

The numbers land as Anthropic briefed investors Wednesday at its San Francisco headquarters while laying groundwork for a stock market listing expected before the end of the year, the BBC reported. An Anthropic spokesperson declined to comment to the BBC. Every revenue and margin figure below comes from those investor briefings or reporting by people familiar with them unless an outlet names a primary document.

How the numbers became public

CNBC’s Jenny Lee and Kate Rooney reported that Anthropic’s revenue jumped to $16.8 billion in the third quarter, according to people familiar with the matter. The outlet said it rose from a second-quarter number of about $11.6 billion, with first-quarter revenue at $4.7 billion, the people said.

That disclosure followed earlier CNBC reporting that the Claude maker planned to disclose its third-quarter financial results for the first time at a meeting with potential investors, including institutional investors, citing two people familiar with the matter. The Wednesday session at Anthropic’s San Francisco headquarters was part of the groundwork for a listing the BBC said is expected before the end of the year.

None of these figures appear in a Form S-1 or other SEC document yet. They are investor-briefing metrics relayed by journalists’ sources—useful for market color, but not substitutes for audited financial statements.

Quarterly revenue trajectory

Revenue has climbed sharply quarter over quarter in 2026, according to people familiar with the investor presentation summarized by CNBC and the BBC:

CNBC’s sources said Anthropic characterized itself as profitable on an adjusted basis in the third quarter. The BBC, citing its own understanding of the briefing, reported that revenue rose in successive quarters from $4.7bn in the first three months to $11.6bn the following period, and that the company also reportedly said it made a profit for the second quarter in a row. Those profitability statements are not GAAP filings; they reflect what Anthropic told investors in a private session.

Compute economics and cash flow

Beyond the top line, Anthropic told investors it was cash-flow positive, generating $1.70 in revenue for every dollar spent on computing power during the third quarter, according to the Financial Times as cited by CNBC.

Bloomberg News, citing people familiar with the matter, said the company posted positive free cash flow and an adjusted gross margin of 85% alongside the $16.8 billion quarterly revenue figure. Bloomberg framed the results as evidence that Anthropic’s artificial intelligence investments are starting to pay off, while noting they may not settle broader doubts about the global AI trade.

Investors expect Anthropic to reach $110 billion in annualized revenue by year-end, according to The Wall Street Journal as cited by CNBC—again, an expectation shared in the investor context, not a published forecast in a regulatory document.

IPO timing and market backdrop

CNBC reported the IPO is reportedly slated for November. Bloomberg said the firm is expected to make its debut no later than the end of the year. Neither outlet published a final offering price or valuation in these revenue stories.

The briefing arrives during a volatile stretch for AI-linked equities. The BBC noted that some technology stocks—including chip makers such as AMD, Nvidia, and Intel—fell sharply on Wednesday amid concerns about hundreds of billions of dollars being spent on AI infrastructure. In Asia on Thursday morning, the BBC reported, shares in Japanese tech investment firm Softbank fell more than 9%. South Korean semiconductor giants were also down, with Samsung falling 9.4% and SK Hynix dropping 10.8%. Tech-heavy indexes in the region were also down: trading on South Korea’s Kospi and Kosdaq was temporarily halted after falling more than 8%, while Japan’s Nikkei 225 fell by over 5%.

The BBC tied part of the selloff to remarks by Hock Tan, chief executive of US tech manufacturer Broadcom, at a conference in Singapore on Monday. Tan said many investors have “no clue” and have set “extreme expectations only to find out that it’s almost like they are in a casino” regarding AI spending.

Bloomberg’s Abhishek Vishnoi wrote that Anthropic’s third-quarter results may strengthen the case for its expected initial public offering, though they are unlikely to dispel doubts over the global AI trade, according to some investors and analysts. The piece noted global AI stocks struggling with rising bond yields as part of that backdrop.

Why the figures matter

For developers and enterprises buying Claude API capacity, the revenue ramp is a proxy for how fast Anthropic is converting model demand into recurring spend—and whether unit economics on compute are improving as inference scales. The $1.70 in revenue for every dollar spent on computing power metric, attributed by CNBC to the Financial Times, is a compute-efficiency metric Anthropic shared with investors in Q3. It is not a margin line item you would find in a 10-Q without footnotes, but it signals how Anthropic wants institutional investors to think about scaling Claude.

Positive free cash flow and an adjusted gross margin of 85%, as Bloomberg’s people familiar described, would—if they hold in audited accounts—answer skeptics who argue frontier labs burn cash faster than they book sales. Again, those are briefing-room numbers until a prospectus reconciles them to GAAP.

For public-market watchers, Anthropic’s trajectory sits beside OpenAI, whose CEO Sam Altman said in September that his company will not go public this year as it addresses concerns about the technology’s safety, the BBC noted. OpenAI is also eyeing a bumper stock market listing expected to value the firm at more than $1tn, according to the BBC. Anthropic has also been vocal about AI’s risks, with CEO Dario Amodei calling on the pace of development to slow down, even as the company continued expanding globally and opened a Singapore office on Wednesday, the BBC reported.

Revenue figures from Anthropic and rival OpenAI, the BBC wrote, offer an important gauge of the AI industry’s growth and ability to finance the infrastructure needed to develop the technology. The BBC also noted concerns over the safety of AI models alongside the infrastructure spending debate—two threads that can pull public sentiment in opposite directions as IPO windows open.

Until Anthropic files registration statements with the SEC, however, outsiders must rely on leaks, investor meetings, and journalism attributed to people familiar—not audited quarterly reports.

What to watch before the listing

Investors tracking the $110 billion annualized revenue expectation cited by CNBC from The Wall Street Journal will want to see whether Q4 run-rate data in the eventual S-1 matches that ambition. A gap between briefing-room annualization and filed revenue could move valuation debates quickly.

Watch also for how Anthropic defines adjusted profitability versus the BBC’s report of profit for a second quarter in a row—different phrasing may map to different non-GAAP measures. IPO candidates often highlight adjusted metrics while regulators scrutinize GAAP net income and stock-based compensation.

On the product side, enterprise Claude adoption and API pricing will determine whether the Q1→Q3 staircase from $4.7 billion to $16.8 billion is a one-year sprint or the new baseline slope. Competitors will parse the same leak for hints about market share shifts versus OpenAI, Google, and Meta.

What’s next

CNBC said Anthropic planned to disclose third-quarter financial results for the first time at the investor meeting. The next verifiable public checkpoint will be formal IPO paperwork, which would subject the numbers to SEC review and standardized accounting. Until then, treat the $16.8 billion third-quarter revenue, $11.6 billion second quarter, and $4.7 billion first quarter as briefing-room figures reported secondhand.

Anthropic declined to comment on the revenue surge to the BBC; CNBC’s story rests on unnamed people familiar with the matter.
