# Gross vs Net: Why Two Honest Numbers for Anthropic's Revenue Differ by Billions — and What That Says About Your ARR

> OpenAI told staff Anthropic's ~$30B run-rate is really ~$22B. Both numbers can be GAAP-legal. The gap is one accounting choice — and the same choice quietly inflates a lot of startup ARR.

## Key takeaways

- In an April 13, 2026 internal memo, OpenAI's chief revenue officer told staff that Anthropic's ~$30B run-rate was overstated by roughly $8B — that on a comparable basis it was closer to ~$22B. The disagreement isn't fraud; it's one accounting choice: gross vs net revenue recognition.
- When a customer buys Claude through AWS, Azure, or Google Cloud, Anthropic books the *full* amount the customer pays as revenue (gross) and records the cloud's commission as an expense. Report it net — only the slice Anthropic keeps — and the top line shrinks by the marketplace cut. Both treatments are legal under US GAAP; which one applies turns on whether you're the 'principal' or the 'agent' under ASC 606.
- Why a founder should care: the exact same choice sits inside your ARR. If you resell an LLM API — bill customers for Claude or GPT with a markup — you may be booking pass-through token spend as your own revenue. That can double a headline ARR that a sophisticated investor will immediately normalize down to the margin you actually keep.
- The rule of thumb: gross when you control the service and bear its risk; net when you're arranging someone else's service for a fee. Know which one you are before a term sheet forces the question.

## At a glance

| Question | Gross (principal) | Net (agent) |
| --- | --- | --- |
| What you record | Full amount the customer pays | Only your fee or margin |
| Partner/cloud commission | A cost line below revenue | Never in your revenue at all |
| ASC 606 test | You control the service; bear its risk; set the price | You arrange another party's service for a fee |
| Effect on headline ARR | Larger — includes pass-through spend | Smaller — reflects what you keep |
| Who it flatters | Fast-scaling resellers and marketplaces | Nobody; it's the conservative number |
| The founder trap | Booking token pass-through as 'your' revenue | — (this is the number investors restate you to) |

## By the numbers

- **~$30B → ~$22B** — Anthropic's run-rate on a gross basis vs the comparable net figure OpenAI's memo cited
- **~$8B** — the gap OpenAI's April 13, 2026 memo attributed to gross revenue recognition
- **ASC 606** — the US GAAP standard whose principal-vs-agent test decides gross or net
- **2–3x** — how far a pass-through reseller's gross ARR can sit above the margin it actually keeps

**The short version:** In an April 13, 2026 internal memo, OpenAI's chief revenue officer told employees that Anthropic's roughly **$30B run-rate** was overstated by about **$8B** — that measured comparably, it was closer to **~$22B**, behind OpenAI's ~$25B at the time ([Implicator.ai](https://www.implicator.ai/openai-cro-tells-staff-anthropic-inflates-run-rate-by-8-billion/)). Nobody is accusing anybody of inventing customers. The entire ~$8B gap comes down to **one accounting choice: gross vs net revenue recognition**. It's the same choice sitting quietly inside a lot of startup ARR — quite possibly yours.
Where the gap comes from
When a customer buys Claude through **AWS, Azure, or Google Cloud**, money flows through the marketplace: the customer pays the cloud, the cloud takes a commission, and the rest goes to Anthropic. The accounting question is how much of that transaction Anthropic gets to call *its own revenue*.
- **Gross (principal) treatment:** record the **full amount the customer pays**, and book the cloud's commission as an expense below the revenue line.
- **Net (agent) treatment:** record **only the slice Anthropic keeps** — the marketplace cut never appears in revenue at all.

Same cash. Same profit. A materially different **top line**. Anthropic books gross; OpenAI reports its Microsoft-channel revenue net of Redmond's cut — so when you line up "$30B" against OpenAI's number, you're comparing a gross figure to a net one. That's the apples-to-oranges the memo was really flagging. Both methods, importantly, are **compliant with US GAAP**.
> Gross revenue answers "how much economic activity flows through this company?" Net answers "how much does it actually keep?" Neither is a lie. The lie is comparing one company's gross to another's net — and then ranking them.

The rule that decides it: ASC 606, principal vs agent
Under [ASC 606](https://asc.fasb.org/1943274/2147480565) (and its international twin, IFRS 15), the gross-or-net call turns on a single word: **control**. Do you control the good or service *before* it's transferred to the customer? If yes, you're the **principal** and you recognize gross. If you're merely *arranging* for someone else to provide it, you're the **agent** and you recognize net.
The standard lists indicators of a principal:
- you're **primarily responsible** for fulfilling the promise to the customer;
- you carry the **risk** if the service fails or the customer doesn't pay;
- you have **discretion in setting the price**.

Run a frontier lab through that test and gross looks defensible: Anthropic runs the inference, owns the model quality, and sets the price — the cloud is closer to a reseller taking a distribution fee. Run a **thin API wrapper** through the same test and it starts to look like an agent: if you just pass tokens through at a markup and the customer knows they're getting Claude, you may be arranging someone else's service for a fee.
Why this is your problem, not just theirs
Here's the part that matters for a company with four employees instead of four thousand. **The exact same lever is inside your ARR.**
If you resell a foundation-model API — you bill customers for usage and pay Anthropic or OpenAI out of it — booking the *full customer payment* as revenue can make your headline ARR look **2–3x larger** than the margin you actually retain. It's not illegal. But it's also not durable: a diligence-stage investor or an acquirer will restate you to net in about ten minutes, and the "growth" that was really just rising **cost of goods sold** disappears from the model. You don't want to discover that your $3M ARR is a $1M ARR *at the table*, after you've anchored a valuation on the bigger number.
The move is boring and it works:
- **Report the number you keep.** Lead with net revenue — your margin after model costs — and show gross separately as "platform volume" if it's genuinely impressive. Sophisticated readers trust the founder who volunteers the net.
- **Know your ASC 606 story before you raise.** If you're clearly the principal (you control the workflow, own the outcome, set the price, eat the risk), gross is fair — say why. If you're closer to an agent, don't inflate; you'll only get repriced.
- **When you compare vendors or competitors, match the basis.** Gross-to-gross or net-to-net. A scoreboard that mixes the two — the thing that just triggered a public spat between the two biggest labs — tells you nothing.

The Anthropic–OpenAI fight is a trillion-dollar version of a question every reseller-shaped startup answers whether it means to or not. The labs will settle theirs in an S-1 footnote reviewed by an army of accountants. You settle yours the first time an investor opens your revenue model — so decide which number is really yours before someone else decides for you.
*This is the accounting question underneath [Anthropic's IPO filing](/posts/anthropic-confidential-s1-ipo-what-a-public-claude-means-for-founders.html). For the strategic side — what a publicly-traded model vendor means for the startup built on it — start there.*

## FAQ

### What exactly did OpenAI accuse Anthropic of?

Per reporting on an April 13, 2026 internal memo, OpenAI's chief revenue officer told employees that Anthropic's roughly $30B run-rate was inflated by about $8B, and that on a comparable basis the figure was nearer ~$22B — behind OpenAI's ~$25B at the time. The claim is specifically about *accounting method*, not invented customers: Anthropic books revenue on a gross basis, counting the full amount customers pay through cloud marketplaces including the partner's commission. Both companies' methods are described as compliant with US GAAP.

### What is gross vs net revenue recognition?

It's the question of how much of a transaction you're allowed to call your own revenue. Under gross (principal) treatment, you record the entire amount the customer pays and book what you owe partners as a cost. Under net (agent) treatment, you record only your own slice — the fee or margin — because you're arranging someone else's service. Same cash flows, same profit; very different top line. The distinction is set out in ASC 606 (and IFRS 15).

### How do you tell whether you're the principal or the agent?

ASC 606 turns on *control*: are you the one who controls the good or service before it reaches the customer? The standard's indicators of a principal include being primarily responsible for fulfilling the promise, bearing the risk if it goes wrong, and having discretion over pricing. A model lab that runs the inference, sets the price, and owns the service quality has a real argument that it's the principal — which is why gross is defensible. A thin reseller that just passes tokens through at a markup looks more like an agent.

### Why does this matter for my startup's ARR?

Because the same lever is inside your numbers. If you wrap a foundation-model API and bill customers for usage, booking the full customer payment as revenue can make your ARR look 2–3x larger than the margin you actually retain after paying the model provider. It isn't illegal, but a diligence-stage investor or acquirer will restate it to net in about ten minutes, and the 'growth' that was really just rising COGS evaporates. Knowing your own gross-vs-net story before you raise keeps you from getting repriced across the table.

### So which number is 'true' — $30B or $22B?

Both, for different questions. Gross answers 'how much economic activity flows through this company?' Net answers 'how much does the company actually keep?' Neither is a lie; they measure different things. The mistake is comparing one company's gross to another's net — which is exactly the apples-to-oranges the OpenAI memo was flagging. When you compare labs, or pitch your own ARR, make sure both sides of the comparison are measured the same way.
