What the First Half of 2026 Shows
Anthropic's revenue rose from $1,163 million to $16,286 million in six months, but its $80,748 million net loss is mostly a valuation mark, not operations.
Anthropic makes Claude, the assistant that drafts these posts, so read this one with that in mind. This is a filing, not a results release: the Form S-1 gives no share price, no share count and no price range, so there is nothing yet to value. Figures are for the six months ended June 30, 2026 (H1 2026) against H1 2025 unless a full year is named, in US dollars, and cash items are kept apart from non-cash ones.
Operations came close to break-even on the filing's own numbers
The operating loss shrank to $693 million from $2,135 million while revenue grew 14 times. Revenue was up 1,300%. The company says higher usage after new model releases drove it, with consumption-based revenue up $12.1 billion and subscription-based up $3.0 billion. Operating margin improved from (184)% to (4)%. The quarterly table shows the turn inside the half: an operating loss of $1,667 million in Q1 2026 and an operating income of $974 million in Q2 2026, on revenue of $11,555 million (8.4%). Compute and infrastructure cost was 55% of revenue, down from 201%, against a compute base that the filing says was primarily committed in advance and did not fluctuate with in-period demand.
The $80.7 billion loss is mostly a non-cash fair-value change
$72,388 million of the net loss is the change in fair value of convertible notes, derivative liabilities and SAFEs, which moves with the company's own valuation. A convertible note» is a loan that converts to shares; when the company's valuation rises, the value of the shares those notes will become rises too, and the increase is booked as a loss. The filing says the changes were "primarily driven by an increase in the fair value of our outstanding convertible promissory notes resulting from an increase in our enterprise valuation". A further $8,757 million of other expense, net, is described as primarily driven by fair-value effects under the note purchase agreements. Interest income of $1,111 million, the operating loss of $693 million and a $21 million tax provision complete the bridge to the $80,748 million net loss: (693) + 1,111 - 72,388 - 8,757 - 21. Neither the fair-value change nor the other expense is described as cash leaving the business.
The cash obligations are the real exposure
The company has $131,651 million of cash and short-term investments, and named compute commitments that add to about $637 billion. Cash from operations was positive, $3.9 billion in H1 2026 against an outflow of $1.5 billion a year earlier, a swing of $5.4 billion, helped by timing of vendor payments and customer receipts as the filing itself says. Against that, the filing lists contracts that oblige it to pay for capacity whether or not it uses it. The filing's own total of committed spend is left blank in the draft prospectus.
The Prescription
For Anthropic, the company-level move the filing points to is to bring compute on in step with revenue: the company says compute is committed ahead of the revenue it supports and that margins may compress as large new capacity arrives, so the commitments, not the headline loss, are what to manage. Do not form a view on this company from the headline loss or the headline growth: read the operating loss ($693 million) for operations and the commitments (about $637 billion across named contracts) for risk, and wait for the price range before deciding anything about value. Stop treating the $80.7 billion net loss as a measure of how the business is doing.
Key Financial Metrics
US$ billion; margin is operating income as a percent of net revenue, per quarter.
| Metric | H1 2026 (USD) | H1 2025 (USD) | Change | Reason |
|---|---|---|---|---|
| Net Revenue | $16,286 million | $1,163 million | +1,300% | Higher usage after successive model and product releases |
| Adjusted EBITDA | Not reported | Not reported | n/a | The filing does not report this measure |
| Operating Income | $(693) million | $(2,135) million | Loss narrowed by $1,442 million | Revenue grew faster than compute cost |
| Net Income | $(80,748) million | $(12,969) million | Loss widened by $67,779 million | $72,388 million fair-value change on convertible notes, derivatives and SAFEs |
The filing instead reports Adjusted Operating Income of $1,618 million (10% adjusted margin) and Adjusted Net Income» of $2,671 million for H1 2026, against $(1,849) million and $(1,741) million a year earlier.
Annual revenue: $41 million (2023), $386 million (2024), $4,585 million (2025). Quarterly revenue rose each quarter from $376 million (Q1 2025) to $11,555 million (Q2 2026).
Key Operational Metrics
- Customers with $100,000 or more of trailing-twelve-month revenue: more than 6,000 at June 30, 2026, from more than 600 a year earlier. They produced $12.0 billion, about 74% of H1 2026 revenue.
- Compute and infrastructure expense as a share of revenue: 55%, from 201%.
- Net Revenue Retention: approximately 900% as of September 30, 2026, a date after the half-year. No arrow is shown because the S-1 gives no prior-period figure for it.
Arrows show the direction since the prior period, with the colour marking whether that is better; no arrow where no prior period is stated.
Beyond the Usual
Named compute contracts total about $637 billion
The filing names Microsoft at least $44.9 billion (non-cancelable except for breach, regardless of actual usage), Google at least about $114.5 billion, Amazon at least $110.0 billion, rent on Broadcom equipment of about $161.2 billion over five-year finance leases[»](/glossary/#finance-lease), SpaceXAI up to $120.5 billion, Nscale about $44.6 billion and Lambda about $41.3 billion. They add to about $637 billion, against $131.7 billion of cash. The mix is not like for like: SpaceXAI can be cancelled on 90 days' notice after early 2027, and some fees accrue only as capacity is delivered. The three non-cancelable cloud contracts alone add to $269.4 billion, 2.05 times the cash. Two more items sit outside the table: an estimated $125 to $150 billion for additional TPU compute, and, for AMD, no fixed dollar commitment but expected spending above $20.0 billion if the full initial capacity is procured.
Three-quarters of revenue comes from about 6,000 customers
Customers with $100,000 or more of trailing-twelve-month revenue produced $12.0 billion of the $16,286 million of H1 2026 revenue, 74%. The filing also says no single customer represented more than 10% of revenue for the nine months ended September 30, 2026. The filing's risk language says Run-Rate Revenue annualizes a short measurement period and may not match revenue ultimately recognized. The 900% retention figure is measured at September 30, 2026, three months after the financial statements end.
The adjusted measures remove $2.3 billion of costs
GAAP operating loss was $(693) million; the filing's Adjusted Operating Income was $1,618 million, a gap of $2,311 million. Stock-based compensation inside personnel cost was $2.2 billion in H1 2026, up from $286 million.
A trust elects the board, and the founders hold 50.1% of votes
The Long-Term Benefit Trust, five financially disinterested trustees, controls a special Class T share that lets it elect and remove directors who will make up a majority of the board. A separate Class F share, to be issued just before the offering to a limited liability company of which the seven co-founders will initially be the sole members, will carry 50.1% of the voting power on general matters. This is a dual-class» structure, and the buyer of Class A shares will not control the board.
Five percent of the company went to a public benefit fund
The company contributed 846,840,960 Class N shares, 5% of fully diluted shares at June 30, 2026, to a wholly owned subsidiary, the Anthropic Public Benefit Fund, and the board can issue up to an additional 2% of then-outstanding shares (plus shares subject to options and other convertible securities) each time the share price rises 50% above the prior milestone, starting at the offering price.
A $1.5 billion settlement, and investors that are also suppliers
The filing records a $1.5 billion settlement of the Bartz copyright class action, agreed in September 2025 and approved in July 2026. It also says Amazon, Google and Microsoft have made significant equity investments in the company, supply much of its compute, and are also its customers and competitors.
Valuation
No verdict is possible. The S-1 sets no price, share count or price range, so there is no market cap, enterprise value or multiple, and no basis for a peer table or a discounted cash flow.
The only share count in the S-1 is the weighted-average of 2,024,972,990 shares (basic and diluted) for H1 2026, used to compute the reported net loss per unit; it is an average over the six months, not shares outstanding at any date, and it excludes the conversions and the new offering, so it cannot be multiplied by a price to give a market cap.
A verdict needs a price and a point-in-time count; until the range is set, any valuation here would be a guess. When it is set, check three things: how much of the fair-value swing falls away once the convertible notes convert (the filing shows a pro forma adjustment for that); how the compute commitments compare with the cash raised; and how many votes the Class A shares carry.
