Anthropic will open its books, a little, on Wednesday.

The AI company behind Claude plans to show institutional investors its third-quarter financials at a meeting at its San Francisco headquarters on October 14, CNBC reported Tuesday, citing two people familiar with the matter. It would be the first time those numbers have been shared, and the timing is no accident. Anthropic is preparing for a possible initial public offering that could value the company at about $2 trillion.

Nothing is confirmed, and Anthropic declined to comment.

What Anthropic is showing investors

Bloomberg previously reported that Anthropic planned to hold an investor day on October 14, giving a select group of institutional investors a chance to question senior executives. CNBC’s report adds the key detail: this meeting is where the third-quarter numbers will appear for the first time.

For investors, the questions are straightforward: how fast is revenue growing, how much does Anthropic burn on computing, and is there a believable path to profit at the scale its valuation implies? People familiar with the company’s plans told CNBC that Anthropic’s annualized revenue run rate could top $100 billion by the end of 2026. That’s a forward-looking estimate, not a disclosed result, and it should be read that way until the company puts real numbers in a public filing.

Anthropic filed confidentially with the Securities and Exchange Commission earlier this year, but it has not yet made its S-1 registration statement public. Until that document lands, Wednesday’s briefing is a private preview for the investors who would price the deal, not a public earnings release. Don’t expect a press release with the figures.

Bloomberg has reported that Anthropic could start formal marketing for the IPO as soon as the week of November 9, positioning it to begin trading before Thanksgiving. Details could still change, and the people describing the plans asked not to be identified because the information isn’t public.

Why the numbers matter right now

Anthropic’s briefing lands at a jittery moment for AI stocks. Earlier this month, confusion over OpenAI’s revenue rattled semiconductor shares and the broader Nasdaq. Media reports initially pegged OpenAI’s annualized revenue at $70 billion, but the Financial Times later reported the figure was closer to $50 billion once revenue from cloud partners was excluded. A person familiar with the matter told CNBC the revision did not reflect weaker demand, but the episode showed how fast a single number can move the market when so little is disclosed.

That’s the backdrop for Wednesday. Investors have spent two years pouring money into AI infrastructure on the strength of growth stories told mostly in private. Now they want receipts. A clean set of third-quarter numbers from Anthropic would give the market something concrete to price.

Anthropic’s pitch, as described in Bloomberg’s reporting, rests on business adoption rather than consumer buzz. Claude doesn’t have ChatGPT’s name recognition, but banks, hedge funds, and enterprise software firms such as Salesforce have built it into their workflows. Steady revenue from business customers is exactly what professional investors say they want to see before backing a listing at this size.

What a $2 trillion Anthropic IPO would mean

Start with what the number is, and what it isn’t. CNBC reported a possible valuation of about $2 trillion. Bloomberg cited a range of $1.8 trillion to $2 trillion from people familiar with the plans. Both figures are unconfirmed scenarios, not an offer price, not a filing, and not a done deal.

Still, the scale is worth pausing on. A listing near $2 trillion would rank among the largest public offerings in history and would put Anthropic, a company founded in 2021, in the same valuation neighborhood as the biggest public tech companies on earth. It would also test a simple question: does the market believe AI labs can grow into their valuations, or has the trade run ahead of the business?

The Pentagon fight hanging over the listing

One risk investors will surely raise on Wednesday has nothing to do with revenue. Anthropic asked a US appeals court on Tuesday to reconsider a ruling that upheld the Pentagon’s decision to label the company a national security supply chain risk, Reuters reported.

A federal appeals court in September upheld the designation in a 2-1 decision, agreeing with the Pentagon that Anthropic’s safety restrictions could compromise military operations. At issue: Anthropic refused to allow its AI to be used in autonomous weapons or mass surveillance. In its petition for a rehearing, Anthropic argued that the panel majority misinterpreted a federal law aimed at hostile foreign actors, and said the designation was “retaliation for Anthropic’s speech about AI safety.”

Anthropic has said the blacklisting has cost it billions of dollars in lost business. In a separate lawsuit in August, a federal judge in California struck down a parallel designation under a different law.

What happens next

Wednesday’s meeting is private, so don’t expect the numbers to appear in public on the day. What to watch instead is the sequence Bloomberg laid out: a formal marketing kickoff as soon as the week of November 9, then a public S-1 filing with audited financials, then a price range. Any slip in that sequence would be a signal in itself.

Anthropic’s numbers will also set a benchmark for the rest of the private AI market. OpenAI has postponed its own IPO plans while raising a new funding round, and investors are comparing every lab’s story against the same doubts about spending and revenue quality. If Anthropic’s third quarter looks strong, it steadies the whole sector.

For now, the company is saying nothing. That silence ends, at least behind closed doors, on Wednesday morning in San Francisco.
