# Anthropic's Leaked Draft Prospectus Targets a Valuation Above $2 Trillion on $4.6 Billion of Revenue

The filing reviewed by Reuters shows a $42 billion net loss for 2025, about $34 billion of it a non-cash charge tied to convertible financing, and $518 billion in planned compute and infrastructure spending.

A draft of Anthropic's prospectus for an initial public offering reached Reuters on Monday, and it contains the most detailed public accounting yet of what it costs to build a frontier AI lab. The company reported [$4.6 billion of 2025 revenue against roughly $13 billion of operating expenses](https://t.me/aipost/8307), an operating loss above $8 billion, and a net loss near $42 billion.

The gap between the operating loss and the net loss is significant. About [$34 billion of the net loss is a non-cash charge](https://fortune.com/2026/09/29/anthropic-ipo-s-1-prospectus-income-statement/) tied to convertible financing that was revalued upward as Anthropic's own valuation rose. No cash left the company because of that item. Anthropic reported $20.28 billion in cash, against a stated plan to spend $518 billion on cloud computing, compute and infrastructure in the coming years.

The risk section is the other unusual feature of the filing. Anthropic devoted [80 pages to risk factors against 48 pages describing the business](https://fortune.com/2026/09/29/anthropic-leaked-ipo-prospectus-losses-growth-ai-end-humanity/), and stated that the technology it is building could pose a catastrophic or existential risk to humanity. That language matches the lab's public position, including the [economic scenario model](https://www.anthropic.com/institute/econ-scenarios) its economics team published this month, and it is now a disclosure item that public-market investors must weigh.

A listing could come as soon as November at a valuation above $2 trillion, according to the reporting. The document is a draft, and neither the valuation nor the timing is final.

## What this means

The mechanism is disclosure. A private lab's cost structure becomes an audited public benchmark that every other AI capital raise gets measured against. Exposed are Anthropic's private-round investors, whose valuations now face a public comparison, the cloud providers holding those $518 billion in forward commitments, and OpenAI, which will face the same questions about revenue relative to compute spending whenever it approaches public markets. The key is separating the accounting from the operating performance: an $8 billion operating loss on $4.6 billion of revenue describes a materially different company than a $42 billion headline loss does. The likelier outcome over the coming months is that gross margin and compute-commitment figures, not the headline valuation, determine how the offering is received, and that rival labs speed up their own disclosures to shape the comparison. This would be proved wrong if the listing is pulled or priced sharply lower than expected, which would indicate that public investors are rejecting the compute-spending strategy rather than the accounting method.

## What to watch

- Whether the final prospectus keeps the existential-risk language in its risk factors. Securities lawyers typically push to soften wording that could increase legal liability.
- Gross margin per dollar of inference revenue in the audited filing. That single figure shows whether serving costs are falling as fast as vendors claim.
- Whether the $518 billion infrastructure figure is backed by signed contracts or only by stated intent. That determines how much of it is a binding obligation on cloud partners.
