Anthropic IPO Explained: What the S-1 Reveals About the AI Boom (and Whether It's a Bubble)

Anthropic filed to list on the Nasdaq as ANT. Here is what the S-1 shows: $16.3 billion in half-year revenue, an $80.7 billion loss, who keeps control, and what it means for AI users.

On 26 October 2026, Anthropic, the company behind the Claude AI models, publicly filed to go public. It plans to list on the Nasdaq under the ticker ANT, with Goldman Sachs and Morgan Stanley leading the offering. NBC News reported that the listing is expected in mid-November and could value the company at more than $2 trillion, which would make it bigger than SpaceX's record IPO in June.

The filing landed three weeks after a bad day for AI stocks. On 8 October, a report that OpenAI's revenue was lower than widely believed pushed the Nasdaq 100 down 1.4 percent and brought the "AI bubble" question back to the front page. So the Anthropic prospectus is being read two ways at once: as the biggest test yet of whether AI companies can make money, and as evidence for or against a bubble.

We build software for businesses in Pakistan and the Gulf, and a lot of it now uses AI models from companies like Anthropic, OpenAI and Google. This post is about what the filing says and what it means if your business relies on these tools. It is not investment advice. Figures are from the S-1 as reported by NBC News and Kepler's breakdown of the filing, and sources are at the end.

What is the Anthropic IPO?

Anthropic filed a Form S-1 registration statement with the US Securities and Exchange Commission on 26 October 2026 for a proposed initial public offering of its Class A common stock. It intends to list on the Nasdaq Global Select Market under the symbol ANT. The number of shares and the price range hadn't been set when it filed. Those come after a roadshow with investors.

An S-1 is the document a company files before selling shares to the public. It has to disclose its finances, risks and ownership in detail, which is why this one is getting so much attention. Until now, outsiders had only estimates of how much Anthropic earned and spent.

How much money does Anthropic make?

Anthropic's revenue for the first six months of 2026 was $16.3 billion, up from $1.16 billion in the same period of 2025. NBC reported growth of 1,368 percent year over year for the three months ended 30 June.

About 80 percent of that revenue ($13.1 billion) came from usage-based charges, mainly businesses and developers paying per use of Claude through the API. The other 20 percent ($3.2 billion) came from subscriptions such as Claude Pro and Max.

A few other numbers from the filing show where the growth came from:

Measure	Figure in the S-1
Customers paying $100,000 a year or more	More than 11,900, up from more than 950 a year earlier
Customers paying $1 million a year or more	More than 1,900
Customers paying $10 million a year or more	About 250
Net revenue retention	About 900 percent as of 30 September 2026
Cash and equivalents	$112.4 billion at 30 June 2026

Net revenue retention of 900 percent means that, as a group, customers who were already paying a year earlier spent about nine times as much in the September 2026 quarter. Anthropic's definition excludes Claude Pro and Max subscribers. It's an unusually high figure, and it tells you the growth came mostly from existing business customers using far more, with new sign-ups adding to it.

Why did Anthropic lose $80 billion?

This is the headline number, and it needs explaining. Anthropic reported a net loss of $80.7 billion for the first half of 2026, after a $42 billion loss in 2025.

Most of that isn't money that left the company. According to Kepler's line-by-line reading of the S-1, $72.4 billion of the half-year loss came from changes in the fair value of convertible notes, derivatives and SAFEs. Those are accounting charges that grow as the company's valuation rises, because the investors holding those instruments are owed more in shares. The operating loss, which reflects the actual business, was $693 million for the half.

The quarter-by-quarter operating results tell a clearer story. Anthropic lost money from operations in every quarter of 2025 and in the first quarter of 2026, then reported operating income of $974 million in the second quarter of 2026.

Compute, meaning the servers and chips that run the models, is the main cost. In the first half of 2025 it was 201 percent of revenue, so Anthropic spent about two dollars on compute for every dollar it earned. In the first half of 2026 it was 55 percent.

That doesn't make the losses irrelevant. The company has committed to enormous future spending. NBC counted $390 billion in compute deals disclosed in the filing: at least $110 billion with Amazon through April 2036, $120 billion with SpaceX through 2029, $115 billion with Google through 2033 and $45 billion with Microsoft through 2033. Anthropic says its current cash and sales should cover the next 12 months, and warns that it "may be required to seek additional financing sooner" than expected.

What risks does Anthropic list?

The filing's risk factors are unusually blunt. As reported by NBC, Anthropic says it may not generate enough revenue to become or stay profitable, that its business is highly capital intensive, that revenue growth may slow, and that its costs and losses are expected to keep rising. It also warns that advanced AI could pose "catastrophic or existential risks to humanity" if it isn't developed with safeguards.

Two other details stand out for business users:

An estimated 5 to 7 percent of revenue in the first nine months of 2026 came from customers later found to be violating Anthropic's usage policies. Anthropic expects that share to fall, which means stricter enforcement.
Management says margins may come under pressure as large blocks of new compute come online, because new capacity costs more per unit in the short term.

Who will control Anthropic after the IPO?

Not the public shareholders. Anthropic is a public benefit corporation, and its share structure keeps control with the founders and a separate trust.

According to the S-1 as summarised by Kepler, a single Class F share issued to an entity owned by the seven co-founders carries 50.1 percent of general votes, which caps all Class A holders combined at 49.9 percent. The Long-Term Benefit Trust, an independent body Anthropic set up to oversee its safety mission, generally elects four of the seven board seats. Strategic partners hold non-voting shares, and employee shares vote only on limited matters. Under Nasdaq rules, Anthropic will be a "controlled company".

For anyone buying shares, that's a big point: you would own part of the profits, but you would have little say in how the company is run.

Is AI a bubble?

Nobody can answer that with certainty, and anyone who tells you they can is guessing. What the filing does is give both sides real numbers to argue with.

The case that it's a bubble:

The amounts involved are extreme. A company that lost $80 billion in six months, even mostly on paper, is asking for a valuation above $2 trillion.
The spending commitments are larger than the revenue by a wide margin, and they run for a decade.
On 8 October, reporting that OpenAI's annualised revenue was about $50 billion, against the roughly $68 billion widely cited, was enough to knock the Nasdaq 100 down 1.4 percent in a day.
Torsten Slok, chief economist at Apollo Global Management, told NBC that outside the tech sector, AI hasn't yet produced a financial payoff for corporate America, and there's no sign yet of a boost to productivity.
Meta announced plans to raise up to $95 billion in stock on the same day Anthropic filed, which shows how much capital the race needs.

The case that it isn't, or at least not for Anthropic:

The revenue is real and growing very fast, and most of it comes from businesses paying for usage, not from speculation.
Thousands of companies now spend more than $100,000 a year, and existing customers are spending several times more each year.
Compute costs fell from twice revenue to about half of it in a year, and the company turned an operating profit in its latest quarter.
Most of the headline loss is an accounting effect of the company's rising valuation.

Both things can be true. A technology can be useful and valuable while the prices investors pay for it run ahead of reality. That happened with the internet in 2000: the share prices crashed, and the internet kept growing. If you're a business using AI tools, the question that matters to you is narrower: will the tools you rely on still be there, at a price you can plan around?

What does the Anthropic IPO mean for businesses that use AI?

For most businesses in Pakistan and the Gulf, nothing changes overnight. Claude, ChatGPT and Gemini will keep working the same way next month. But a few things are worth thinking about.

First, prices. Anthropic's compute costs have fallen sharply relative to revenue, which reduces the pressure to raise API prices. At the same time, a listed company answers to shareholders every quarter, and the filing warns about margin pressure. Don't build a business case that only works if AI prices keep falling.

Second, rules. With 5 to 7 percent of revenue linked to policy violations, expect tighter enforcement of usage policies. If your product sits in a grey area, read the policies again now, not after your account is suspended.

Third, information. As a public company, Anthropic will have to report results every quarter. For the first time, businesses choosing an AI provider will be able to see how one of the major ones is doing financially.

Fourth, don't depend on one provider. If the AI market does correct, providers may change prices, retire models or change terms. Build your systems so you can switch models with a configuration change, not a rewrite. We cover how to price and plan for this in our guide to what an AI agent costs in 2026.

When will Anthropic shares start trading?

NBC News reported the offering is expected in mid-November 2026. Other reports point to trading as early as 16 November, but Anthropic hasn't announced a date, and the price range will only be set after the roadshow. Treat any specific date as a reported target until it's confirmed.

Key takeaways

Anthropic filed for its IPO on 26 October 2026 and plans to list on the Nasdaq as ANT, with Goldman Sachs and Morgan Stanley leading.
Revenue for the first half of 2026 was $16.3 billion, up from $1.16 billion a year earlier, with 80 percent from usage-based business customers.
The $80.7 billion half-year loss is mostly a $72.4 billion non-cash accounting charge. The operating loss was $693 million, and the second quarter showed an operating profit of $974 million.
Anthropic has disclosed hundreds of billions of dollars in compute commitments over the next decade.
Founders and the Long-Term Benefit Trust keep control after the IPO.
Whether AI is a bubble is still open. For businesses, the practical step is to avoid depending on a single AI provider.
