Anthropic generated $33.24 billion in revenue over the first nine months of 2026 while recording a net loss of $104 billion, according to an amended Form S-1 the maker of the Claude AI assistant filed with the U.S. Securities and Exchange Commission as of November 2, 2026. The filing is part of the company's preparations for a potential Nasdaq listing under the ticker symbol ANT.

While the size of the loss draws attention, the drivers behind it matter more than the headline figure itself.

A Loss That Mostly Exists on Paper

The bulk of the $104 billion net loss does not represent cash that left the company. According to the filing, it primarily reflects non-cash accounting charges tied to the rising fair value of convertible notes and derivative liabilities.

The mechanics are worth understanding: when a company's implied valuation climbs, the fair value of convertible instruments it has issued rises along with it, and accounting rules require that increase to be recorded as a loss — even though no money actually leaves the business.

Fair-value charges on the convertible notes totaled $72.4 billion in the first half of 2026, with an additional $23.3 billion in the third quarter. Together, those two figures account for most of the reported loss.

Revenue Growth at an Unusual Pace

Once the accounting charges are set aside, the top line stands out. Revenue of $33.24 billion for the nine-month period represents growth of approximately 1,200% year over year.

Third-quarter revenue reached nearly $17 billion, with estimates placing it between $16.96 billion and $17 billion. That equates to roughly 1,127% growth compared with the same quarter a year earlier and a 47% increase from the second quarter.

Customer metrics point in the same direction: the company counts more than 11,900 customers that each generate at least $100,000 in trailing twelve-month revenue.

There is, however, a caveat on the operating side. Anthropic swung to an operating loss of $567 million in the third quarter after posting an operating profit in the second quarter, meaning the core business slipped back into the red before the convertible-note charges, even as sales surged.

The $895.4 Billion in Commitments

Where the net loss is largely an accounting matter, the commitments figure involves real money. The filing discloses approximately $895.4 billion in purchase commitments and lease agreements, primarily for compute and infrastructure. These are contractual obligations — amounts the company has committed to pay in future periods — and the kind of forward obligation prospective shareholders typically scrutinize in a prospectus.

For context, Anthropic has raised roughly $141 billion in capital to date and holds a considerable cash reserve, but its forward commitments amount to several times that total. The company has itself flagged infrastructure costs as a critical variable and warned that it may require additional funding.

How the Filing Came Together

The amended filing follows Anthropic's initial S-1 and earlier reports of significant losses in 2025 and the first half of 2026. An S-1 is the registration document a company files with the SEC before its shares can be offered to the public, laying out financials, risk factors, and business details; successive amendments are a standard part of the process as the offering is refined ahead of pricing. The contemplated listing could rank among the largest initial public offerings ever, with early discussions among investors reportedly pointing to a valuation near $1.5 trillion. Nothing regarding final pricing or timing has been confirmed, and the IPO remains a potential event rather than a completed transaction.

Reading the Two Sides of the Filing

The document presents two distinct pictures of the company. One is a business adding revenue at a pace few companies of any size have matched, supported by a broad base of high-value customers. The other is a business that has committed to nearly $900 billion in infrastructure obligations and states outright that it may need more capital.

The non-cash charges warrant careful reading. Because they are linked to the company's valuation, reported net income could vary dramatically from quarter to quarter without any change in the underlying business. The convertible notes also represent potential future dilution for shareholders.

The operating line may be the more telling metric. The move from an operating profit in the second quarter to a $567 million operating loss in the third illustrates how quickly compute costs can erode gains, even with revenue up 47% in a single quarter.

Items to watch going forward include any further amendments to the S-1, the final IPO pricing and timing, and how Anthropic describes its plans to fund the compute commitments.
