On Monday, Anthropic filed its S-1 prospectus to go public on the Nasdaq under the ticker “ANT,” and for the first time we can see its books. The growth is staggering. Revenue went from $41 million in 2023 to $386 million in 2024, $4.6 billion in 2025, and $16.3 billion in just the first six months of 2026.

So are the losses. Net loss went from $1.5 billion in 2023 to $8.3 billion in 2024, $42 billion in 2025, and $80.7 billion in the first half of 2026. A Wall Street Journal report noted that pace would dwarf the record for the largest annual loss ever reported by a public company. As of June 30, Anthropic’s accumulated deficit stood at $132.9 billion.

Here’s the part most headlines skip. About $72.4 billion of that six-month loss came from changes in the fair value of convertible notes and similar instruments, which the company says were driven mainly by its own rising valuation. In plain English: as Anthropic got more valuable, what it owes early investors who hold convertible notes went up on paper. It’s a real accounting loss, but it is a non-cash expense.

Strip that out and the picture changes, but doesn’t get comfortable. The operating loss was $8.1 billion in 2025 and $693 million in the first half of 2026. The business is getting close to breaking even, but only because revenue is growing faster than its enormous compute bill. Compute and infrastructure alone cost $8.9 billion in the first half of 2026. And the company has signed compute and infrastructure commitments that stretch from now through 2045, with the total dollar figure still blank in this draft filing.

The $80 billion headline overstates how much cash Anthropic is burning.

But the real worry is that the whole business depends on revenue continuing to grow at an extraordinary pace to cover compute bills it has already promised to pay for nearly two decades. If growth slows even a little, those commitments don’t shrink.

That’s a big bet, and soon everyday investors will be asked to share it.

How worried?: 🟠 4/5 — Serious

(Pls note: This is a hypothetical scenario, not a prediction.)

Imagine ANT prices well below expectations, or opens and slides. Anthropic itself would be fine for a while thanks to its cash pile. The bigger danger is what it would signal to everyone else.

The AI industry is built on a web of companies that are each other’s investors, suppliers, and customers. Cloud giants invest in AI labs, the labs spend that money renting those same clouds, and chipmakers sell to both. Amazon, for example, holds convertible notes in Anthropic that convert to shares at the IPO. A weak debut would force investors to mark down those stakes and ask harder questions about the hundreds of billions in AI spending they’ve been funding.

That spending is already making markets nervous. AI infrastructure costs around $1 trillion a year and climbing, and tech companies are borrowing heavily through bonds, crowding out demand for other debt, including Treasuries. On October 22, the Nasdaq fell 2.6%, and Reuters reported the semiconductor index was more than 26% below its June record. An expected wave of fall AI IPOs hasn’t materialized, and OpenAI has reportedly pushed its own IPO to next year.

If the most-anticipated AI listing stumbles, the window could slam shut for others. Chipmakers could see order books questioned. Lenders could charge more to fund data centers. And the jobs and 401(k)s tied to the AI boom would feel it. The flip side is that a strong debut could do the opposite and pour fuel on the trade. Either way, ANT is becoming a referendum on the entire AI economy. And maybe the entire U.S. economy.
