Anthropic S-1 Filing Reveals $17B Q3 Revenue and $895B in Compute Deals

Anthropic S-1 filing updates landed on Monday, and the numbers are huge. The Claude maker added fresh results to its paperwork for an initial public offering (IPO). They show soaring sales, slower growth and a giant bill for computing power. We read the amended filing at the SEC and the main news reports. Here is what matters for investors, including readers in Germany.

What the Anthropic S-1 Filing Is and What It Says

An S-1 is the form a US company files with the Securities and Exchange Commission (SEC) before it sells shares to the public. Anthropic filed its public version on Oct 26, NPR reported. On Nov 2 it filed Amendment No. 1, which added results through Sept 30, according to CNBC.

Here are the basics we can confirm from the filing:

• Proposed ticker: ANT, on the Nasdaq Global Select Market.
• Price range: still blank on the cover page.
• Share count: also blank, so no one can size the deal yet.
• Lead banks: Goldman Sachs and Morgan Stanley are listed first among the underwriters.

Anthropic is not trading yet. So we cannot show a live stock page for it.

Anthropic Q3 Revenue Hits $17 Billion, but Growth Slows

Anthropic Q3 revenue reached about $17.0 billion, the filing says. That is up 1,127% from the same quarter last year. Over nine months, revenue hit $33.24 billion. A year earlier, it was about $2.5 billion.

Growth is cooling, though. CNBC reports that third-quarter revenue rose about 47% from the second quarter. By comparison, the second quarter grew 144% and the first grew 132%. The business is still booming. The pace of the boom is easing.

The customer numbers are strong. The filing lists more than 11,900 customers that spend at least $100,000 a year. About 250 of them spend $10 million or more. The company also says its Opus 5.5 model cut customer costs per task by roughly 40%. We covered that price move in our Opus 5.5 pricing story.

Why the Net Loss Looks So Big

Anthropic lost $104 billion over nine months. That sounds scary. CNBC says most of it came from a change in the fair value of convertible notes and similar items. In plain words, those notes gained value as Anthropic’s own valuation rose. The filing books that gain as a loss. It is not cash leaving the bank.

The cleaner number is the operating loss. It was $1.26 billion for nine months. In the third quarter, the operating loss was $567 million. In the second quarter, the company had a $974 million operating profit, Yahoo Finance reported. German news agency dpa made the same point in a report on t-online.

The company still has a large cushion. At the end of September, it held $95.6 billion in cash and $36.3 billion in short-term investments.

The $895.4 Billion Compute Bill Inside the Anthropic S-1 Filing

The biggest eye-opener is the spending promise. Anthropic says it has signed purchase and lease deals worth about $895.4 billion. Almost all of it covers computing power and data centers. The filing breaks it down:

• About $447.5 billion is due before Dec 31, 2030.
• About $69.8 billion is due in the 12 months after Sept 30.
• Most of the rest comes between 2031 and 2045.

Compute spending is already rising fast. Anthropic spent $18.8 billion on it in nine months. That is $14.4 billion more than a year earlier, CNBC notes. The company gets much of its capacity from Amazon (AMZN), Alphabet (GOOGL) and SpaceX. Yahoo Finance adds that Amazon, Alphabet and Nvidia (NVDA) are major investors.

This bill worries some investors. CNBC says last week’s results from Microsoft (MSFT), Alphabet and Amazon fed fears about AI spending. Rising interest rates add to the worry. For a wider view, see our piece on how a big AI listing could shake markets.

One more detail stands out. German tech site t3n reports that Anthropic now spends more on its own AI use than on staff pay. That uses list prices and leaves out stock pay. Real costs are likely lower.

Timing and Valuation After the Anthropic S-1 Filing

Dates are not official yet. A person familiar with the plan told IFR that the roadshow would start on Nov 9. Pricing would follow the next week. German business magazine WirtschaftsWoche expects the listing in the second half of November. Treat both as reports, not promises.

Value is also open. Anthropic’s last private round valued it at $965 billion, as we noted in our earlier IPO filing story. The Wall Street Journal reported, via Yahoo Finance, that investors now suggest $1.5 to $1.6 trillion. Talk of $2 trillion came earlier. None of these figures is final.

Rival OpenAI is not racing to follow. CNBC says it filed confidentially in June but is aiming for 2027.

How German Investors Could Join the Anthropic IPO

Germany’s retail investors may get a direct route. WirtschaftsWoche reports that Trade Republic told customers on Monday it will act as an approved broker for the IPO. It is the first German broker to say so. More brokers are expected to follow.

Details are still thin. Trade Republic said more information would come in the next days. Past experience offers a warning, though. In the SpaceX IPO, customers chose an amount in the app and paid the usual one-euro settlement fee. Demand was so high that they received only 12.95% of what they ordered. The rest went back to their accounts.

The prospectus also lists public offerings in the European Economic Area, Switzerland, the UK, Canada, Australia and Japan. Anthropic does not plan to list shares on exchanges there. So the stock would trade in the US.

Key Risks in the Anthropic S-1 Filing

The filing has more than 90 pages of risk factors, CNBC says. A few stand out for us:

• Compute supply: failing to secure enough computing power could slow model training and customer service.
• Customer concentration: a small group of customers and channels drives much of the revenue.
• Competition: Anthropic faces OpenAI and several big tech rivals.
• Governance: the founders hold a special share worth 50.1% of the votes. A trust also elects most of the board. Public buyers would have limited say.
• Short history: the company says past growth may not predict future growth.

Anthropic is also a public benefit corporation. Its board must balance profit with a stated mission on safe AI. That can pull against short-term returns. We explored the retail angle in our guide to AI stock debuts and 401(k)s. We also covered the valuation debate in this analysis of the share sale.

What We Are Watching Next

• A new amendment that prints the price range and share count.
• The start of the roadshow, where investors question management.
• The final price and how many shares retail brokers receive.
• Fourth-quarter growth, after the slowdown from 144% to 47%.

The Anthropic S-1 filing shows a company growing at a rare speed while promising to spend almost $900 billion. Both facts can be true at once. Smart investors will read the risk pages before they read the headlines.
