Key takeaways

Reuters and The Wall Street Journal reported on 20 October 2026 that a draft IPO prospectus for Anthropic shows a net loss of $80.7 billion for the first half of 2026, up from $13 billion a year earlier.
About $72 billion of that loss is a non-cash accounting charge linked to the rising estimated value of convertible instruments, not money spent running the business, according to Reuters.
Revenue for the six months to 30 June was reported at $16.3 billion, against $1.1 billion a year earlier (WSJ, as cited by Al Jazeera).
The prospectus has not been made public. Anthropic confirmed in June that it had confidentially submitted a draft Form S-1 to the SEC, but it did not respond to requests for comment on the new figures.
The headline loss, the operating loss and cash burn are three different measures. Investors in AI companies preparing to list are watching all three.

What was reported

Anthropic's net loss reached $80.7 billion in the first half of 2026, up from $13 billion a year earlier, according to a draft IPO prospectus reviewed by Reuters. About $72 billion of it is a non-cash charge linked to convertible instruments. Reports have since put a value on early backers' stakes; see what an Anthropic IPO could mean for Spark Capital and Iconiq.

Both outlets traced most of the loss to one line item. Reuters described a $72 billion accounting charge reflecting a higher estimated value of bonds that could convert into Anthropic shares, and said the charge did not represent cash operating costs. Al Jazeera, citing the Journal, described $72 billion in non-cash charges tied to changes in the value of convertible notes and other financial instruments the company used to raise money.

Al Jazeera, again citing the Journal, reported revenue of $16.3 billion for the six months ended 30 June, up from $1.1 billion a year earlier. Reuters reported that second-quarter revenue more than doubled from the first quarter to $11.6 billion. Reuters also cited people familiar with an investor meeting on 14 October, where Anthropic reportedly told prospective IPO investors that third-quarter revenue rose 45% from the previous quarter to $16.8 billion. That third-quarter figure comes from unnamed sources, not from the draft document, and Reuters said some investors were disappointed that growth had slowed from quarter to quarter.

Reported versus on the record

Readers should know where these figures come from. None of them has been published by Anthropic or appeared in a public SEC filing. As of 21 October, an EDGAR company search for "Anthropic" returned only investment vehicles that use the name, and no registration statement from the company itself.

What is on the record is narrower. On 1 June 2026, Anthropic announced that it had "confidentially submitted a draft registration statement on Form S-1" to the SEC for a proposed IPO of its common stock. The company said the share count and price had not been set and that the offering would depend on market conditions. Under SEC staff procedures, a company that uses the confidential review route must file its registration statement and earlier drafts publicly at least 15 days before the roadshow for an IPO. If the listing goes ahead, audited figures should become public before shares are marketed.

Until then, the numbers are draft figures that news organisations say they have reviewed. Draft financial statements can change during SEC review. Anthropic did not respond to requests for comment from Reuters or Al Jazeera, and Al Jazeera noted that the figures could not be independently verified.

The numbers side by side

Measure	Full year 2025	H1 2025	H1 2026	Reported by
Revenue	Nearly $4.6bn	$1.1bn	$16.3bn	Reuters (2025); WSJ via Al Jazeera (H1)
Net loss	About $42bn	$13bn	$80.7bn	Reuters
Non-cash charge on convertible instruments	About $34bn	Not reported	About $72bn	Reuters
Operating loss	More than $8bn	Not reported	Not reported	Reuters
Compute and infrastructure spending	$7.33bn	$2.3bn	Nearly $9bn	Reuters

Figures are as reported up to 00:00 UTC on 21 October 2026. The full-year 2025 numbers come from Reuters' 28-29 September reports on an earlier draft prospectus. All figures are in US dollars, rounded as published.

Net loss, operating loss and non-cash charges

The size of the headline loss makes more sense once three measures are separated.

Operating loss

Operating loss is revenue minus the cost of running the business: computing power, staff, research and sales. For 2025, Reuters reported an operating loss of a little over $8 billion on nearly $4.6 billion of revenue, with about $7.33 billion spent on compute and infrastructure. This measure shows whether the core business costs more than it brings in. The reports seen so far do not give an operating figure for the first half of 2026.

Non-cash charges on convertible instruments

Fast-growing private companies often raise money through notes or similar instruments that can later convert into shares. Under US accounting rules, some of these instruments are carried on the balance sheet at their estimated fair value. When the company's valuation rises, the instruments are worth more to their holders, so the liability grows and the increase is recorded as a loss. No cash leaves the company. As a result, a company whose valuation is climbing can report a larger net loss because of that climb.

Reuters reported that the estimated fair value of these notes roughly tripled during 2025 as Anthropic's valuation rose, producing a charge of about $34 billion. The first-half 2026 charge was about $72 billion. Such instruments usually convert into equity when a company lists, and the charge does not normally recur once they do. The exact treatment will be set out in the final prospectus.

Net loss

Net loss is the bottom line after everything: operating results, financing items such as fair-value changes, interest and taxes. Subtracting the $72 billion charge from the $80.7 billion net loss leaves about $8.7 billion. That remainder is a simple difference and should not be read as the operating loss, because other financing and tax items may be included.

Why the distinction matters for AI labs heading to market

Large AI developers combine fast revenue growth with very large spending on chips and data centres. Each of the three measures answers a different question. The operating line shows whether the products cover their running costs. Cash flow and commitments show how much capital the business needs. Non-cash fair-value charges mostly reflect the price at which the company has raised money.

The commitments are large. Reuters reported that Anthropic has committed to spend at least $518 billion over a decade on cloud services, computing and infrastructure. Al Jazeera, citing the Journal, reported that the company indicated it could spend up to $750 billion on additional computing capacity in coming years, including deals still under discussion. Reuters' September report also said nearly a quarter of 2025 revenue came from two customers, and that many large customers are not bound by long-term contracts.

Investors are scrutinising AI spending well beyond the labs. Tesla cut its 2026 capital-spending plan to about $20 billion, and Reuters reported its shares slipped as investors questioned Musk's AI and robotics push. Policy is changing the funding picture as well: a proposed Treasury rule under the COINS Act would turn US investment in Chinese AI companies into an outright ban.

What it means

For readers following the AI sector, the $80.7 billion headline says more about how Anthropic raised money than about how its products performed during the half. Most of it is an accounting result of the company's rising valuation. The figures that will shape the IPO debate are less dramatic: how fast revenue keeps growing, how large the operating loss is relative to that revenue, and how the company will fund hundreds of billions of dollars in compute commitments.

Valuation is the other open question. Reuters reported that some investors are weighing a valuation of around $1.5 trillion after the latest disclosures. Al Jazeera described an earlier expectation of roughly $2 trillion for a share sale anticipated in November. Neither figure has been confirmed by the company. Reuters added that a cooler reception could weigh on the wider AI market, and that rival OpenAI may list next year. Several things are still unknown: the final audited figures, the first-half operating result, the offering size and price, and the listing date. They should become clearer once a public S-1 is filed.

Frequently asked questions

How large was Anthropic's reported first-half 2026 loss?

Reuters and The Wall Street Journal reported a net loss of $80.7 billion for the six months to 30 June 2026, compared with $13 billion a year earlier, based on a draft IPO prospectus. Anthropic has not published or confirmed the figures.

Why is the loss so large?

According to Reuters, about $72 billion is a non-cash accounting charge reflecting the higher estimated value of convertible instruments that could turn into Anthropic shares. It is not cash spent on operations.

What is the difference between net loss and operating loss?

Operating loss measures the cost of running the business against revenue. Net loss also includes financing items such as fair-value changes on convertible notes, plus interest and taxes. For 2025, Reuters reported an operating loss of a little over $8 billion against a net loss of about $42 billion.

Is Anthropic's prospectus public?

No. Anthropic announced on 1 June 2026 that it had confidentially submitted a draft Form S-1 to the SEC. Under SEC staff procedures, the registration statement must be filed publicly at least 15 days before an IPO roadshow.
