Anthropic IPO revenue: the draft prospectus shows $16.3 billion in first-half sales and an $80.7 billion loss, as reported

Anthropic's IPO revenue figures have surfaced from its draft prospectus. On October 20, 2026, The Wall Street Journal reported that Anthropic brought in $16.3 billion of revenue in the first half of 2026, up from $1.1 billion a year earlier. The same day, Reuters, which said it had reviewed the draft, reported a first-half net loss of $80.7 billion. Most of that loss, about $72 billion, was an accounting charge on convertible bonds, not cash spent running the business. Anthropic hasn't published the document. Its IPO date, price and ticker remain unconfirmed, as our Anthropic IPO explainer sets out.

This analysis is based on Reuters' October 20 report (read through syndicated wire copies), the WSJ's report as relayed by Al Jazeera, Investing.com and The Next Web, Reuters' September reporting on the same draft, and searches of SEC EDGAR, checked October 23, 2026. It describes reported facts only and isn't investment advice.

The short version

• Revenue (WSJ): $16.3 billion in the six months to June 30, 2026, against $1.1 billion a year earlier.
• Net loss (Reuters): $80.7 billion in the first half, against $13 billion a year earlier.
• Why the loss is so large (Reuters): a $72 billion accounting charge tied to a rise in the estimated value of bonds that can convert into Anthropic shares. Reuters says the charge was not a cash operating cost.
• Compute spending: nearly $9 billion in the first half (Reuters and the WSJ), against $2.3 billion a year earlier (Reuters) and $7.3 billion in all of 2025 (WSJ).
• Commitments: the reported totals range from about $450 billion to about $750 billion, depending on the outlet and what is counted.
• Not public: no Anthropic S-1 appears in EDGAR as of 9:50 a.m. ET on October 23, 2026. Yahoo Finance reported on October 21 that Anthropic could file it publicly as soon as that day. Anthropic didn't respond to Reuters.

What did the draft prospectus report about Anthropic's revenue?

The WSJ reported first-half 2026 revenue of $16.3 billion, according to Al Jazeera and Investing.com, which both attribute the figure to the Journal. Reuters' October 20 story doesn't give a first-half total. It says second-quarter revenue "had more than doubled from the first quarter to $11.6 billion." Taken together, the two reports imply first-quarter revenue of about $4.7 billion, the same figure our $16.8 billion quarter analysis used.

That $16.8 billion is a different period. It's third-quarter revenue (July to September), which Reuters, the FT and Bloomberg reported from an October 14 investor meeting. So one quarter, Q3, roughly equaled the whole first half. There's no conflict between the $16.3 billion and $16.8 billion figures, only a difference in periods.

There is one small conflict. The FT, as summarized by TechCrunch on September 28, put second-quarter revenue at $11.5 billion, while Reuters says $11.6 billion. Neither report says whether partner sales are counted gross or net, the question raised in our revenue accounting explainer.

Why is Anthropic's net loss over $80 billion?

Mostly because of an accounting charge, according to Reuters. Its October 20 report says the loss was "in large part due to a rise in the fair value of bonds convertible into shares," and describes "a $72 billion accounting charge reflecting an increase in the estimated value of bonds." Reuters says the document describes this as not a cash operating cost. The WSJ, as relayed by Investing.com, called it non-cash adjustments tied to convertible notes and other financing instruments.

A convertible bond is debt that can turn into shares. When a company's estimated value rises, those instruments become worth more, and under the accounting rules the draft applies, the increase is booked as a loss. Neither report explains the specific accounting standard, and neither breaks down the remaining roughly $8.7 billion of the loss (the $80.7 billion total minus the $72 billion charge). We don't speculate about what that remainder contains.

The same pattern shows up in 2025. Reuters reported in September that Anthropic's 2025 net loss was $42 billion, and Computing, summarizing that report, said about $34 billion of it came from an accounting charge. Excluding the charge, Reuters says, Anthropic had an operating loss of about $8.1 billion on $4.6 billion of revenue.

So the cash picture is smaller than the headline, but it is still a loss. First-half compute spending of nearly $9 billion is more than half of first-half revenue, and above the $7.3 billion the WSJ says Anthropic spent on infrastructure in all of 2025.

How much has Anthropic committed to spend on compute?

The answer depends on which report you read, and they don't match:

WSJ: cloud deals over 7–10 years	450

Axios, citing WSJ: future infrastructure costs	600
WSJ: possible spend incl. deals under negotiation	750

• Reuters: "Anthropic has committed to spending at least $518 billion over a decade on cloud services," computing and infrastructure. Computing's summary of Reuters' September story said the $518 billion covers infrastructure from six partners.
• WSJ, via Investing.com and The Next Web: about $450 billion of cloud agreements over the next seven to ten years, most of them noncancelable, including $111 billion with Google Cloud, $110 billion with AWS and $31 billion with Microsoft.
• Axios, citing the WSJ, as summarized by The Next Web: more than $600 billion in future infrastructure costs, with deals under negotiation that could add about $150 billion.
• WSJ: Anthropic could spend about $750 billion in coming years, including deals still being negotiated.

These aren't necessarily contradictions. They appear to count different things: signed cloud contracts, all infrastructure partners, and deals not yet signed. But no report we read reconciles them, and a summary syndicated on Yahoo Finance lists itemized deals that add up to neither total. Until the S-1 is public, treat each figure as one outlet's reading of a draft. Debt raised to pay for some of this compute is covered in our story on Anthropic's credit rating.

What else did the reports say is in the draft?

• Customer concentration: about 20% of first-half revenue came from two customers, the WSJ reported, via Investing.com. The FT had reported in September that nearly a quarter of 2025 revenue came from two unnamed clients, according to TechCrunch.
• Capacity: the WSJ reported that Anthropic said it sought more capacity than cloud providers were willing to supply, and is pursuing third-party data center projects.
• Risk factors: the draft warns of liability from severe AI incidents that could exceed insurance limits, and of model behaviors such as attempts to resist shutdown, according to the WSJ and earlier Reuters reporting.
• Governance: earlier reporting on the same draft described a founders' vote and the Long-Term Benefit Trust's board role, covered in our trust explainer. The WSJ also reported the co-founders' pledges of 80% of their equity, which Anthropic counted alongside the Public Benefit Fund it announced on October 18.

Is Anthropic's S-1 public yet?

Not yet. Searches of SEC EDGAR at 9:50 a.m. ET on October 23, 2026, found no S-1 filed by Anthropic and no EDGAR filer registered under the name Anthropic PBC. That may change soon: Yahoo Finance reported on October 21, citing three people familiar with the plans, that Anthropic could file its S-1 publicly as soon as Friday, October 23. Anthropic didn't comment on the timing. Anthropic said on June 1, 2026, that it had confidentially submitted a draft. Under SEC guidance, as our IPO explainer notes, a confidentially filed S-1 must be made public at least 15 days before the roadshow. Reuters reported on October 20 that the IPO is expected in November. Al Jazeera, citing Reuters, said investors discussed a valuation around $1.5 trillion, below the roughly $2 trillion previously reported. None of that has been confirmed by Anthropic.

What's confirmed, reported and uncertain

• Confirmed: Anthropic confidentially submitted a draft S-1 on June 1, 2026. No public S-1 appears in EDGAR as of 9:50 a.m. ET on October 23.
• Reported (Yahoo Finance, October 21): Anthropic could file its S-1 publicly as soon as October 23.
• Reported (Reuters, which reviewed the draft): the $80.7 billion first-half loss, the $72 billion non-cash charge, nearly $9 billion of compute spending, $11.6 billion Q2 revenue and at least $518 billion of commitments.
• Reported (WSJ, via relays): $16.3 billion first-half revenue, the 20% two-customer share, $7.3 billion of 2025 infrastructure spending, and the $450 billion and $750 billion commitment figures.
• Uncertain: what makes up the rest of the loss beyond the charge; how the commitment figures relate; whether the final S-1 will match the draft; gross vs net revenue treatment.
