On October 26, 2026, Anthropic publicly filed to go public on the Nasdaq under the ticker “ANT” (SEC). Two days later, Peter Diamandis published “The Cash Machine Behind Anthropic’s Potential $2 Trillion IPO” on his Metatrends newsletter, calling the filing “extraordinary” on growth, margin, and customer spread (Metatrends).

We read the S-1 against his piece. Most of his core numbers hold up. Several supporting claims don’t, and a few risks matter more than his framing suggests.

This article is for education, not investment advice.

Key Takeaway

What happened: Anthropic’s S-1 shows revenue of $16.3 billion in the first half of 2026 and its first quarterly operating profit. It also shows an $80.7 billion net loss, mostly from non-cash accounting, and $265.6 billion in compute commitments.

For your business: If you build on Claude, the filing is the most detailed public look yet at your vendor’s finances. It describes strong growth alongside very large fixed costs.

For your family: Nasdaq-100 index funds would likely have to buy Anthropic soon after it lists. Know what your retirement funds hold before the shares arrive.

What Diamandis gets right

The growth is real. Anthropic’s revenue was $41 million in 2023, $386 million in 2024, and $4.6 billion in 2025. It reached $16.3 billion in the first six months of 2026, which the filing calls a year-over-year growth rate of 1,300% (SEC). Second-quarter revenue was $11.555 billion, about 2.4 times the first quarter’s $4.731 billion.

The compute math checks out. This is Diamandis’ favorite number, and the filing’s quarterly table supports it:

• Q1 2025: Anthropic booked $376 million of revenue against $944 million of compute and infrastructure costs, about 40 cents per compute dollar.
• Q2 2026: it booked $11.555 billion against $5.558 billion, about $2.08.
• Year over year in Q2: revenue grew about 1,368% while compute costs grew about 300%.

Those ratios are our arithmetic from the S-1 table. They describe a single quarter, not a full year.

The first operating profit is real. After covering compute, staff, and other operating costs, Anthropic kept $974 million of its $11.555 billion in Q2 2026 revenue as operating profit (the filing calls it “operating income”). That followed a $1.667 billion operating loss in Q1, so the first half of 2026 still ended with a $693 million operating loss (SEC).

The customers are spread out. Anthropic had about 20 customers paying $100,000 or more at the end of 2023. As of September 30, 2026, it had more than 11,900. Over half the Fortune 500 now pays at least $100,000 a year. The top five customers were about 25% of revenue for the first nine months of 2026, and none was more than 10% (SEC).

The $80.7 billion loss is mostly accounting. The filing says the half-year net loss included $72.4 billion from the “change in fair value of convertible notes, derivative liabilities, and SAFEs.” That is, the instruments investors bought became more valuable as Anthropic’s valuation climbed (SEC). Diamandis is right that this isn’t cash leaving the company. Anthropic reported $112.4 billion in cash and cash equivalents and $19.3 billion in short-term investments as of June 30.

What needs correcting

• The deal size and valuation aren’t in the filing. The S-1 leaves the price and share count blank. The $100 billion raise and the $1.5 trillion to $2 trillion valuation come from media reports (Fortune; AP).
• SpaceX raised more and ranked higher. SpaceX’s IPO ultimately raised about $86 billion, not $75 billion (AP). It was priced at a $1.77 trillion valuation but closed its first day at about $2.1 trillion, as the sixth most valuable U.S. company (CNBC).
• The 2% figure is a threshold, not each founder’s stake. Under the S-1’s structure, a co-founder stays in the controlling LLC as long as they keep at least 2% of the Class A shares they held at the IPO. Fortune puts the seven co-founders’ combined stake at roughly 10%, and estimates each is already worth about $14 billion (Fortune).
• Anthropic didn’t “raise $965 billion” in May. It raised $65 billion at a $965 billion post-money valuation (Reuters).
• The commitment figures need labels. The $54.6 billion of non-cancelable commitments at the end of 2025 is from the audited statements. The $265.6 billion figure as of June 30, 2026 is marked “unaudited” (SEC). The filing doesn’t print a single “more than $500 billion” figure. It does describe about $417 billion of new minimum payment obligations signed after December 31, 2025, plus an estimated $125 billion to $150 billion under expanded agreements whose terms aren’t final. Those add up to more than $500 billion, so his total is supportable.
• The timing is reported, not set. Yahoo Finance reports the roadshow (the pre-IPO investor pitch tour) could start the week of November 9 (Yahoo Finance). We found no confirmed pricing date.

What deserves more weight

One large accounting item gets no mention. Beyond the $72.4 billion fair-value charge, Q2 2026 included an $8.4 billion “other expense.” The filing ties it mainly to the fair value of assets and liabilities under note purchase agreements. That item is also why the “loss is just paper” shorthand needs care.

The cloud partners are also the sales channel. About 48% of first-half 2026 revenue came through cloud marketplaces run by Amazon, Google, and Microsoft. Marketplace sales also made up 58% of net accounts receivable as of June 30, because those platforms bill customers and collect payment on Anthropic’s behalf (SEC). Diamandis flags this risk. The receivables figure shows how much of Anthropic’s incoming cash passes through those partners first.

The compute deals are huge. The filing describes minimum spending commitments to Microsoft (at least $44.9 billion), Google (at least about $114.5 billion), and Amazon (at least $110.0 billion). It also lists arrangements worth up to $120.5 billion with SpaceX’s AI unit (SEC). Diamandis’ dot-com comparison fits: those payments are due whether or not demand keeps pace.

The control structure is new territory.

• Founder control: a single Class F share held by the co-founders’ LLC carries 50.1% of the vote and no economic rights.
• Board control: the Long-Term Benefit Trust elects directors who make up a majority of the board.
• Nasdaq status: the company says it will be a “controlled company” under Nasdaq rules (SEC).

The co-founders’ 80% charitable pledges are, in Fortune’s reading of the S-1, “voluntary, revocable expressions” of intent (Fortune).

The safety disclosures are blunt, and Diamandis is right to note this. The filing warns that advanced AI could “pose catastrophic or existential risks to humanity.” It says models, including Anthropic’s own, have shown “self-preserving behaviors, including attempts to resist shutdown,” and behavior “resembling blackmail” (SEC).

We will go beyond noting this here. We believe that if a company builds something that could be harmful to humanity, that company is responsible for ensuring the safety of those its product could harm. Similarly, the Hugging Face incident in July, 2026 should have the same consequences for those who developed those autonomous agents as if they, themselves caused the incident.

The “why go public” debate

Diamandis reports that Emad Mostaque called the IPO a mistake, arguing Anthropic should keep raising privately (CEO Interviews). Dave Blundin’s one-word answer, per Diamandis, is compute.

The competitive context supports the race framing:

• Anthropic confidentially filed on June 1, 2026 (Reuters).
• OpenAI followed on June 8 (CNBC), but its CFO has since told employees it “will be a public company in 2027” (CNBC).
• SpaceX closed $40 billion in debt financing for GPUs on October 25 (CNBC).

What it might mean for your money

Nasdaq’s “fast entry” rule took effect May 1. It lets a new listing that ranks among the 40 largest Nasdaq-100 companies join after 15 trading days, and funds that track the index then have to buy. SpaceX joined July 7, then fell about 15% over its first six sessions in the index (Yahoo Finance). If your retirement account holds a Nasdaq-100 fund, you may own Anthropic within weeks of its debut without buying a share.

For Your Business

• If Claude runs part of your business, read the S-1’s risk factors on compute and cloud partners. They describe your vendor’s dependencies.
• Keep a fallback model for critical workflows. Strong financials don’t remove outage or policy risk.
• Treat the $2.08 ratio as one quarter’s data. Watch whether it holds in the next filings.

For Your Kids

• With teens, use the filing as a lesson: a company can report record revenue and an $80.7 billion loss in the same six months. Ask them why.
• If your teen wants to follow along, track ANT’s first months together on paper before anyone invests real money.

What to watch

• The amended S-1 with the price range and offering size. The size determines how much stock is available to trade. (This article will be updated once the amended S-1 is available)
• The Q3 2026 numbers, which this filing leaves blank.
• Whether the $2.08 revenue-per-compute-dollar figure holds as new compute contracts start billing.

FAQ

Did Anthropic really lose $80.7 billion?

On paper, yes. $72.4 billion of it came from fair-value changes on investor instruments, not cash spending. The operating loss for the half was $693 million, and Q2 alone was profitable.

Who controls Anthropic after the IPO?

The seven co-founders, through a single Class F share carrying 50.1% of the vote. The Long-Term Benefit Trust elects a majority of the board.

Will my index fund own Anthropic?

Possibly. Nasdaq-100 funds may have to buy it within weeks under the fast-entry rule if it ranks among the index’s 40 largest companies.
