Anthropic's $11.5B quarter turns on whether cloud-partner sales are booked gross or net
The run rate climbed from about $9B to more than $65B in seven months, and prospective buyers are now asking for the accounting basis rather than the growth story, because the gross-or-net answer moves the multiple and the margin in opposite directions.
The Investor · Invest desk
What happened
- Preliminary second-quarter 2026 revenue was $11.5B, against $4.73B in the first quarter of 2026 and $787M in the same quarter a year earlier.
- The company posted its first quarterly operating profit in that quarter, approximately $559M.
- A confidential draft S-1 went to the SEC in June 2026, and the public filing is anticipated in late September with a roadshow potentially starting in mid-October.
Why it matters
- What it limits constraint The one concentration datapoint on offer, 1,000-plus customers each spending at least $1M a year, accounts for at least $1B, or about 1.5% of a $65B run rate, so it cannot tell a buyer where the other 98% sits.
- Who has to decide decision The two cloud providers holding about 36% of the equity between them are also the channel whose revenue treatment is in dispute, so the syndicate has to decide whether that revenue prices like third-party demand.
- Who's exposed exposure Amazon's roughly 21% holding is worth about $203B at the private mark and about $420B at $2 trillion, so its largest single AI position swings by around $217B on a print it does not control.
- What it sets up precedent Every AI issuer behind Anthropic in the queue gets priced against whatever multiple this book clears at, which is why the definition of the revenue line travels well beyond one company.

Nscale seeks a $35bn listing with cost of revenue running $49m above revenueConfirmed6 publishers
Two revenue numbers are in circulation and they do not describe the same thing. A quarter of $11.5B annualizes to $46B [23], while the run rate quoted for the end of July, in figures cryptobriefing.com reports are being shared with prospective backers, was above $65B [1], which leaves roughly $19B of the headline figure resting on whatever July alone did [24]. That implies about $5.4B of revenue in July against a second-quarter average nearer $3.8B a month [25]. Annualizing an exit month is a normal thing to do when the growth is real and the cash is collected; it is also the presentation that flatters fastest, and it matters because the multiple hangs off which denominator the book uses. At a $2 trillion price, the candidates are about 31 times the run rate and about 43 times the annualized quarter [10], and the whole distance between them is a choice of window.
The reseller question is a second lever on the same denominator. When Claude is sold through a partner, booking gross means the full amount the customer pays and booking net means Anthropic's share after the cloud provider's cut [12], and prospective IPO investors are pressing on which is being used [11]. If a slice of that revenue is presented gross and later restated to net, revenue falls while operating profit does not, because gross presentation adds the provider's cut to revenue and to cost of revenue in equal measure [26]. So the $559M reported for the second quarter is the durable figure and the 4.9% operating margin it implies against $11.5B [21] is the fragile one, which also decides whether the comparable set is software or the distribution of someone else's compute. Enterprises are about 80% of revenue [13], and many of the largest reach Claude through AWS Bedrock or Google Cloud's Vertex AI [15].
Internal projections put 2028 revenue at $190B to $200B [5], which is 2.9 to 3.1 times the current run rate and 4.1 to 4.3 times the annualized quarter [19]; at the top of that range, $2 trillion is 10 times 2028 revenue [20]. Against that, the same report notes fewer than four quarters of meaningful history from which to model churn, seasonality or customer concentration [8]. The $65B Series H closed in late May at $965B post-money [4], which is between 50% and 55% of every private dollar the company has ever raised [32], so the marginal private holder is a few months old and needs a print above its own mark, and $2 trillion is 2.07 times that mark [16].
The counter-thesis is respectable. The cash is the same cash whichever line it lands on, sequential growth of 2.43 times [30] is not something a presentation convention manufactures, and the extrapolation to 2028 is a larger hole in the book than the bookkeeping. What would break the accounting thesis is a filing that shows channel revenue as a modest share already presented net, at which point pricing goes back to arguing about the trend line. None of these figures sit in a public document yet, since the June draft was confidential and the public version is only anticipated for late September [22]. The denominator becomes checkable then.
What to watch
- Whether the late-September filing breaks revenue out by channel or aggregates direct and cloud-marketplace sales into a single line.
- Any restatement between the confidential June draft and the public S-1, which the SEC comment process would drive.
- Whether the mid-October roadshow range opens above or below the $965B post-money mark set in late May.

Claim ledger
Ranked by verification strength, evidence, and original report placement.
- [1]
Anthropic's annualized revenue run rate grew from roughly $9B at the end of 2025 to over $65B by the end of July 2026.
- [2]
Some prospective IPO investors are projecting a public market valuation north of $2 trillion.
- [3]
Anthropic posted its first quarterly operating profit, approximately $559M, in Q2 2026.
- [4]
A record $65B Series H completed in late May 2026 valued Anthropic at $965B post-money.
- [5]
Internal revenue projections for 2028 sit in the $190B to $200B range, according to figures being shared with potential backers.
- [6]
Anthropic confidentially submitted its draft S-1 registration statement to the SEC in June 2026, working with Goldman Sachs, Morgan Stanley and JPMorgan as underwriters.
- [7]
The public filing of the S-1 is anticipated in late September 2026, with a roadshow potentially starting in mid-October.
- [8]
Revenue growing from $787M to $11.5B in a year leaves very little historical baseline for predicting churn, seasonality or customer concentration risk, and investors projecting $190B to $200B for 2028 are extrapolating from fewer than four quarters of meaningful data.
- [9]
Anthropic's preliminary Q2 2026 revenue was $11.5B, up from $4.73B in Q1 2026; Q2 2025 revenue was $787M.
- [10]
A $2 trillion valuation is about 31 times a $65B run rate and about 43 times the annualized second quarter of $46B.
- [11]
Prospective IPO investors are focused on how Anthropic accounts for revenue generated through cloud reseller partnerships.
- [12]
When Anthropic sells models through a partner such as AWS or Google Cloud, the question is whether it books the full amount customers pay (gross) or only its share after the cloud provider's cut (net).
- [13]
Enterprise customers account for roughly 80% of Anthropic's revenue.
- [14]
Over 1,000 businesses were spending at least $1M annually on Anthropic's products as of April 2026.
- [15]
Many enterprise customers access Claude through AWS Bedrock or Google Cloud's Vertex AI, so the gross-versus-net question touches a significant portion of total revenue.
- [16]
A $2 trillion valuation is 2.07 times the $965B post-money mark set in late May 2026.
- [17]
Amazon holds approximately 21% of Anthropic and Alphabet owns around 15%.
- [18]
A 21% stake in a company valued at $2 trillion would be worth roughly $420B.
- [19]
2028 projections of $190B to $200B are 2.9 to 3.1 times the current run rate and 4.1 to 4.3 times the annualized second quarter.
- [20]
At $200B of 2028 revenue, a $2 trillion price is 10 times 2028 revenue.
- [21]
A $559M operating profit on $11.5B of quarterly revenue is a 4.9% operating margin.
- [22]
Because the draft S-1 was submitted confidentially in June 2026 and the public filing is only anticipated for late September 2026, none of the reported figures are yet in a public SEC document.
- [23]
Q2 2026 revenue of $11.5B annualizes to $46B.
- [24]
The stated end-July run rate of more than $65B exceeds the annualized second quarter by roughly $19B.
- [25]
A $65B annualized run rate implies about $5.4B of monthly revenue, against a Q2 average of about $3.8B a month.
- [26]
Because gross presentation adds the cloud provider's cut to both revenue and cost of revenue, a restatement from gross to net lowers reported revenue while leaving operating profit in dollars unchanged, so the margin percentage rises as the revenue multiple worsens.
- [27]
The 1,000-plus customers spending at least $1M a year account for at least $1B of annualized revenue, about 1.5% of a $65B run rate.
- [28]
Amazon and Alphabet together hold about 36% of Anthropic.
- [29]
Amazon's 21% stake is worth about $203B at the $965B post-money mark and about $420B at $2 trillion, a difference of roughly $217B.
- [30]
Second-quarter revenue of $11.5B is 2.43 times the first quarter's $4.73B.
- [31]
Anthropic has raised between $118B and $130B in private capital across its funding history.
- [32]
The $65B Series H is between 50% and 55% of the $118B to $130B of private capital Anthropic has raised in total.
- [33]
Anthropic's IPO will function as a pricing signal for the AI industry, and a $2 trillion valuation would effectively set a new ceiling for what public markets pay for frontier AI capabilities.
