Anthropic IPO: $2 Trillion Valuation,
History's Largest?

Today's numbers at a glance

The table below lists each figure with its source and reporting date. Note the split: valuation, raise size and timetable are reported second-hand from unnamed sources and have not been confirmed by Anthropic, while the financial figures come from a draft prospectus obtained by Reuters and the Financial Times.

1. A timetable that has slipped from September to November

The listing chatter has moved repeatedly this year: late September was expected over the summer, then mid-October, and at one point the schedule was said to be pushed back again to avoid volatility around the US midterm elections on 3 November. The latest version is a roadshow in the week of 9 November, aiming to trade before Thanksgiving on 26 November, with the company said to want the deal done by year-end at the latest.

Why the rush before Thanksgiving? Because trading activity and investor attention thin out sharply afterwards, which underwriters treat as a practical cut-off. Anthropic is also reported to be planning an investor day on 14 October.

The shifting timetable is itself informative: a company valued in the trillions would rather wait than price into an unreceptive market. For retail investors, the lesson is that until the pricing date, every valuation figure is a target, not a fact.

2. How $2 trillion is calculated: the same company, a 14-fold difference

For an unlisted or newly listed company, the most common shorthand is the price-to-sales ratio — market value divided by revenue. The catch is which revenue. That single choice can change the conclusion entirely. Using the two revenue figures disclosed for Anthropic:

The same $2 trillion valuation is 435x 2025 revenue, 31x the end-July run-rate and 19x the year-end expectation — a spread of more than 14 times. This is the single most common mistake in valuing a high-growth company: without knowing the base, the multiple means nothing.

Dilution is another angle: a $100 billion raise against a $2 trillion valuation equates to roughly 5% new shares. Also note the company was valued at $965 billion post-money in May, meaning its reported value could double again within six months.

3. Reading a $42bn loss: $34bn is not cash

"A net loss of close to $42 billion" is the most quotable number, but unpacking it reveals three layers.

Layer one: about $34 billion is a non-cash accounting charge. It comes from the rising value of convertible instruments that may later convert into shares. That revaluation flows through the income statement, but the company did not pay out that cash.

Layer two: the true operating loss was $8.06 billion, up from $2.98 billion in 2024 — roughly 1.7 times wider. That is the number that reflects operations. It widened largely because of compute spending: $7.33 billion on compute and infrastructure in 2025, about three times the 2024 figure and more than half of total operating expenses of $12.65 billion.

Layer three: cash. At the end of 2025 the company held $20.28 billion in cash, cash equivalents and short-term investments. Reports also say it is finalising a pre-IPO revolving credit facility of about $15 billion to fund further compute spending.

A general rule for loss-making companies: first ask whether the number is cash or non-cash, then whether it is one-off or recurring. The same headline "$42 billion loss" describes two different things depending on which layer you are reading.

4. Two long-dated commitments: $518bn of compute and $42bn of financing

The draft prospectus discloses at least $518 billion of compute and infrastructure commitments over ten years, around 80% of which cannot be cancelled. Against $20.28 billion of cash and short-term investments at end-2025, that commitment is roughly 26 times the cash position — the structural trade-off of high growth that requires heavy upfront spending.

A second arrangement drawing attention is financing. According to Reuters, citing the filing, chipmaker Broadcom has agreed to provide up to $42 billion of financing for Anthropic's AI infrastructure build-out. The filing also discloses that Broadcom acts as both hardware supplier and financing partner, which may create a potential conflict of interest. The market calls this pattern "reciprocal spending" — a supplier lending money to a customer to buy its own products.

Supporters see it as using financial strength to drive chip sales; sceptics question whether the end-customer revenue of AI companies is sufficient to support such heavy infrastructure investment. Both readings can hold, but for an investor the practical point is this: when reading AI-related results, look at how much revenue comes from the same group of shareholders and customers, because that revenue is not the same quality as revenue from an unrelated third party.

5. SpaceX and recent listings: two ways a hyped IPO ends

If Anthropic lists at $2 trillion and raises $100 billion, it would beat the record set by SpaceX in June this year (a valuation of about $1.77–1.8 trillion and a raise of $75–86 billion). The underwriting syndicate is reported to include Morgan Stanley, Goldman Sachs, JPMorgan and Citi, with Nasdaq the expected venue.

But big, hyped and profitable are three separate things. On 29 September, four Hong Kong IPOs debuted on the same day and three fell below their issue price immediately. One company's public tranche was more than 200 times subscribed with a 60% one-lot allocation rate, and its shares still barely moved on day one; another with a subscription rate below 3x and a 100% allocation rate fell more than 10%. There was also an extreme case at the other end: a stock listed on 30 September, more than 3,500 times subscribed, opened about 1.85 times higher — and gave back a large part of those gains on the next trading day.

The conclusion is the same every time: subscription multiples and allocation rates measure demand, not return. Judging whether a new listing is worth it still comes down to two questions — what price are you paying, and what assumptions justify that price.

6. Three things Hong Kong investors must understand before taking part

First, there is no IPO subscription mechanism like Hong Kong's. Hong Kong IPOs include a public tranche where retail investors apply, with a lot size, an entry cost and an allocation rate. Large US IPOs allocate shares mainly to institutions and major clients through the syndicate, so retail investors generally buy in the secondary market after listing. In other words, the IPO price is not an order you can place; what you actually pay is the post-listing market price.

Second, understand the trading mechanics.Buying US shares requires a broker with US market access, and the session runs through Hong Kong's evening and early morning. The USD/HKD rate affects your realised return in Hong Kong dollar terms, and commissions, platform fees and regulatory levies add up. There are also no daily price limits on US stocks, so first-day moves can be extreme in both directions.

Third, do not confuse a great company with a good price. A leading AI company listing is an industry milestone, but valuation is a separate matter. Buying the same stock at 19x sales and at 435x sales are two entirely different bets: the first assumes moderate growth, the second assumes growth multiplying several times over. Knowing which assumption you are buying matters far more than predicting the first-day move.

7. Three things to do before placing an order

One, fix the base first. Before looking at any multiple, establish which period the revenue covers, whether it is a full-year or annualised figure, and whether it is booked or collected. The same company can produce a 14-fold difference.

Two, separate cash from accounting. Work out how much of a loss is non-cash and how much is one-off, then compare the cash position against long-dated commitments.

Three, write your assumptions down. Before buying, write two sentences: what revenue do I assume in a few years, and what multiple am I applying. When the price moves later, you will know whether your assumption broke or it is just sentiment.

Frequently asked questions

Q1: When will Anthropic list?As of 2 October it remains a report, not a confirmed plan. Bloomberg, citing sources, points to a roadshow in the week of 9 November, a listing before Thanksgiving on 26 November and completion by year-end at the latest. The timetable has been revised several times and the company has not confirmed it.

Q2: Is a $2 trillion valuation reasonable?There is no single answer. On 2025 revenue of $4.6 billion the price-to-sales ratio is about 435x; on an end-July run-rate above $65 billion it is about 31x; on the year-end expectation, about 19x. Whether it is reasonable depends on which revenue base and growth assumption you accept.

Q3: Is a $42 billion loss alarming?Look at it in layers. About $34 billion is a non-cash accounting charge. The true operating loss was $8.06 billion, roughly 1.7 times wider year on year, but it includes $7.33 billion of compute spending that is investment in future capacity. The key question is whether $20.28 billion of cash at end-2025 can support the long-dated commitments.

Q4: Can Hong Kong residents subscribe to Anthropic's IPO?Generally no. Large US IPOs allocate mainly to institutional investors, so retail investors typically buy in the secondary market after listing, at the post-listing price rather than the IPO price. You need a broker with US market access, and you should factor in exchange rate, trading hours and fees.

The bottom line: valuation is a question, not an answer

"$2 trillion" is a striking number, but behind it sits a set of assumptions: which revenue base, how long growth persists, and who ultimately carries the 80% of compute commitments that cannot be cancelled. Read the same document pessimistically and optimistically, and you get two different stories.

For an investor, the most valuable thing is not being first to call the first-day move, but building a repeatable method: establish the base, separate cash from accounting, and write your assumptions down. Those three steps will not make you right every time, but they will make your losses legible.
