**Mikirduit –** Anthropic has released a preliminary prospectus ahead of its planned IPO, which is targeted to list in mid-November 2026\. The filing leaves some key terms blank, but it already reveals a lot about the company’s growth, spending commitments, and how insiders may sell shares. Here are five takeaways for investors.

### Key Takeaways

- **Growth is explosive but cooling.** First-half 2026 revenue jumped 1,300% to $16.28 billion, but quarterly growth slowed from 144.2% in Q2 to 45.4% in Q3\. Reported IPO valuation talks have reportedly fallen to around $1.5 trillion from earlier expectations of about $2 trillion.
- **Spending commitments are enormous.** Anthropic has recorded $265.6 billion in long-term purchase commitments and $321.4 billion in signed leases that haven’t started, while remaining performance obligations are only $10.8 billion.
- **Share supply and dilution are the main risks.** Lock-ups release shares in stages through 2027, and convertible notes, new funding commitments, and Broadcom’s $42 billion convertible facility could add dilution. The final share count is still unknown.

## Key terms are still blank

The prospectus does not yet state the number of new shares or the offering price. It does say the offering will include shares sold by existing shareholders (“selling stockholders”). Those proceeds go to the sellers, not to Anthropic.

The filing doesn’t say who will sell or how many shares they will offer. It does indicate that the company’s seven founders could be among the sellers. Their listed holdings are:

- Dario Amodei: 240.63 million shares
- Daniela Amodei: 241.4 million shares
- Tom Brown: 244.71 million shares
- Jack Clark: 242 million shares
- Jared Kaplan: 242 million shares
- Sam McCandlish: 231.8 million shares
- Christopher Olah: 242 million shares

These figures are not all issued, outstanding stock. They also include shares held through trusts, options exercisable within 60 days, and restricted stock units.

## Revenue is growing faster than compute costs, but net loss is huge

In the first half of 2026, revenue rose 1,300% to $16.28 billion. Compute costs rose 283% to $8.94 billion. Operating loss narrowed to $693 million, from $2.13 billion a year earlier.

The net loss, however, ballooned to $80.74 billion, compared with $12.96 billion in the same period last year. Most of that comes from non-cash accounting charges. Changes in the fair value of convertible notes, derivative liabilities, and SAFEs totaled $72.38 billion. Together with other financial instruments, fair-value changes totaled $81.1 billion.

Growth is also slowing from its peak. According to Reuters, third-quarter 2026 revenue rose 45.4% to $16.8 billion. That is still strong, but well below the second quarter’s 144.2% growth to $11.55 billion.

After these disclosures, some investors have reportedly discussed an IPO valuation of around $1.5 trillion, below earlier expectations of about $2 trillion. That figure is not an official offering valuation set by the company.

## Two revenue streams: usage-based and subscriptions

Anthropic earns money in two ways:

- **Consumption-based (80.2%):** Customers pay based on how much they use Claude, measured in tokens. This brought in $13.06 billion in the first half of 2026.
- **Subscription-based (19.8%):** Consumers pay for plans with usage limits. This brought in $3.22 billion.

Geographically, the U.S. accounted for 72.2% of revenue ($11.76 billion). International markets contributed about $4.52 billion.

## Massive spending commitments could pressure margins

Anthropic has committed to infrastructure payments over the next several years, but the revenue to cover them is not yet locked in. Remaining performance obligations (RPO) were only $10.8 billion as of June 2026, and most revenue is usage-based and can change with customer activity.

The prospectus lists two large recorded items:

- Long-term purchase commitments of $265.6 billion
- Signed leases that have not yet started, worth $321.4 billion, with start dates expected between 2026 and 2028

Among the contracts disclosed:

- **Microsoft:** at least $44.9 billion, November 2026 to May 2033
- **Google:** at least $114.5 billion, April 2026 to July 2033
- **Amazon:** at least $110 billion, May 2026 to April 2036
- **Additional Tensor processing unit capacity:** $125 billion to $150 billion, to be delivered in 2028–2031, depending on capacity and deployment
- **SpaceXAI:** $120.5 billion through 2029
- **Nscale:** $44.6 billion through 2033
- **Lambda:** $41.3 billion through 2034
- **AMD:** $20 billion, if initial capacity is fully delivered

## Lock-up rules 

Anthropic has set up four lock-up categories. Shares are released in stages rather than all at once.

**Non-founder directors, officers, and certain employees and consultants:** Up to 10% of holdings can be sold starting from the first trading day. Another 35% can be sold after FY2026 earnings are announced. The remainder can be sold after Q1 2027 earnings.

**Certain investors (up to 180 days):** Shares are released in steps. About 26% becomes available on days 27, 48, 62, and 76 after the prospectus date (6%, 6%, 7%, and 7%). Another 12.5% is released after FY2026 earnings, followed by 9.5% every 14 days over the next five periods. The rest is released at the earlier of Q1 2027 earnings or day 180.

**Certain large investors (up to 365 days):** This applies to holders of more than 0.5% of fully diluted shares before the IPO, though not every such holder is automatically included. Shares are released in smaller steps over a longer period, with the final portion released at the earlier of Q3 2027 earnings or day 365.

**The seven founders:** They can sell in three stages:

1. In the IPO itself, they may sell Class A shares allocated to the offering.
2. At the earlier of Q1 2027 earnings or day 180, they may sell 29% of their holdings.
3. At the earlier of Q3 2027 earnings or day 365, they may sell the rest.

## Dilution risk

It is too early to measure dilution, since the number of new shares is unknown. But the filing points to four sources:

1. **Preferred stock conversion.** All outstanding preferred shares are expected to convert automatically into Class A or Class N common stock just before the IPO closes. This isn’t necessarily new dilution for IPO buyers if the conversion is already built into the share count used for valuation. The filing also lists past preferred purchases, including Google’s $10 billion and Amazon’s $5 billion in the Series H round, and Series H-1 purchases by Spark Capital entities (about $440 million) and Bodhi LLC (about $10 million). These are not the investors’ total holdings.
2. **Amazon’s older rollover notes.** As of June 2026, Amazon held rollover notes with about $6.203 billion in principal. At the disclosed fixed conversion price, they could convert into about 1.84 billion Class N shares, before applying an ownership cap. Some may convert at the IPO, while any portion held back by the cap could stay outstanding and convert later.
3. **New funding commitments.** Amazon ($15 billion), Google ($20 billion), and AMD ($5 billion) have committed new funding that could dilute shareholders if drawn. The money may not all be used right away.
4. **Broadcom’s convertible facility.** Broadcom is letting Anthropic defer certain lease payments by issuing convertible debt, in a facility totaling $42 billion.

The overall picture is still unclear because the filing doesn’t yet give the share count or the remaining capacity under these debt and preferred-stock arrangements.

## The bottom line

Anthropic’s growth is remarkable, but the IPO comes with real risks: slowing quarterly growth, enormous spending commitments, a staggered but substantial supply of shares coming to market, and open questions about dilution.

Macro conditions matter too. If the IPO happens in mid-November, a possible 50-basis-point rate hike in December 2026 could weigh on sentiment. Higher rates could also affect floating-rate credit facilities. And if the stock falls, convertible financing priced off the volume-weighted average price (VWAP) would convert into more shares for the same amount of funding, increasing dilution.

For short-term traders, the stock could become interesting once it stabilizes after any early selling pressure. For long-term investors, the picture still looks volatile, especially if rates rise aggressively because of inflation driven by higher commodity prices.
