OpenAI’s reported annualized revenue is about $50 billion—not $70 billion—in Axios’s October 8, 2026 report. The earlier $70 billion figure was described as a comparison-oriented gross-up intended to align OpenAI’s presentation more closely with Anthropic’s. The difference reflects how some cloud-partner sales are presented, but it does not mean the two companies’ underlying customer payments changed by $20 billion or that accounting explains their entire revenue gap.
Why did OpenAI’s figure change from $70 billion to $50 billion?
Axios reported on October 8, 2026, that OpenAI’s annualized revenue was about $50 billion. The roughly $70 billion figure reported earlier was an effort to gross up OpenAI’s revenue for a more direct comparison with Anthropic’s accounting presentation. Axios characterized the newer $50 billion figure as the company’s annualized revenue and the $70 billion figure as a comparison adjustment—not as two audited results or a published reconciliation. Axios’s October report does not provide enough public detail to reproduce the adjustment.
That distinction matters: a gross-up changes how a top-line figure is presented for comparison. It is not, by itself, evidence that OpenAI earned an extra $20 billion in customer payments, or that the company’s actual revenue suddenly fell by that amount.
How the companies treat some cloud-partner sales
The difference described by Axios is gross versus net presentation for certain sales made through cloud partners. In the explanation reported by Axios, Anthropic includes the full customer payment in revenue and records the cloud provider’s share as an expense. OpenAI records only its own share for certain partner sales. Axios’s September explainer describes the distinction.
#1 Best Overall
| Presentation | What appears as revenue | Where the partner’s share appears |
|---|---|---|
| Gross presentation described for Anthropic’s partner sales | The full customer payment | As an expense |
| Net presentation described for certain OpenAI partner sales | OpenAI’s share | Excluded from OpenAI’s reported revenue |
For a simplified illustration, if a customer pays $100 through a partner and the partner retains $20, gross presentation would show $100 of revenue and $20 of expense; net presentation would show $80 of revenue. The illustration isolates presentation only: it does not establish either company’s actual contract terms, margins, or overall accounting treatment.
Why the accounting judgment depends on the transaction
The relevant accounting question is whether a company is the principal or an agent in a particular sale. Axios’s accounting coverage says that assessment turns on transaction facts, including who controls the customer relationship and who is responsible for delivering the service. The companies may both comply with GAAP while reaching different conclusions for different arrangements; GAAP compliance alone does not make their figures directly comparable. The underlying contracts and accounting memoranda needed to assess the companies’ specific judgments are not publicly established in the cited reporting.

What the Anthropic revenue figures measure
Anthropic’s revenue headlines refer to different periods and kinds of measurement. A run rate extrapolates a recent pace; it is not the amount earned during a completed year. A preliminary quarterly figure refers to a particular quarter, while a July run rate projects from the pace at that point.

| Figure | What it describes | Source and qualification |
|---|---|---|
| $14 billion | Anthropic’s current run-rate revenue at the time of its 2026 Series G announcement | Company-reported run rate, not audited annual revenue. Anthropic’s Series G announcement |
| More than $11.5 billion | Preliminary Q2 2026 revenue | Axios attributed the figure to Bloomberg reporting. It is preliminary quarterly revenue, not a full-year result. Axios’s August report |
| Above $65 billion | Anthropic’s July 2026 run rate | Axios attributed the figure to Bloomberg reporting; it is a projection from a short period, not revenue booked in July or during a completed year. Axios’s August report |
| Above $65 billion for Anthropic; above $40 billion for OpenAI | Annualized revenue figures cited in September 2026 reporting | Axios cautioned that these were not apples-to-apples. Its report said accounting could not explain the entire reported $25 billion difference on the information then available. Axios’s September explainer |
| About $50 billion for OpenAI; about $70 billion as an earlier comparison gross-up | OpenAI annualized revenue and a prior comparison-oriented presentation | Figures reported by Axios on October 8, 2026; not a public audited reconciliation. Axios’s October report |
Anthropic’s Series G announcement also said it had more than 500 customers spending over $1 million annually on an annualized basis, up from 12 two years earlier. That is a company-reported customer metric, not a revenue figure for a completed year. The same announcement said run-rate revenue had grown more than tenfold annually in each of the preceding three years.
Earlier milestones help show how quickly the reported pace changed, but they should not be confused with current booked revenue: Anthropic reported about $1 billion in run-rate revenue at the beginning of 2025 and more than $5 billion in August 2025. Anthropic’s 2025 Series F announcement gives those company-reported milestones.
Are the companies’ revenue figures comparable?
Not reliably from the headlines alone. Before comparing them, an investor needs to know whether each number is booked revenue or an annualized run rate, how long the measurement window is, which sales channels and revenue streams are included, and whether partner sales are reported gross or net. A figure from one month’s pace cannot be treated as equivalent to revenue earned over a completed year.
Accounting presentation is only one part of the apparent gap. In September, Axios said the available information did not allow accounting differences to explain the entire reported $25 billion difference. That is a dated assessment, not a final reconciliation: public reporting cited here does not provide a complete company-to-company bridge across periods, channels, and accounting treatment.

What revenue headlines do not tell investors
Run-rate revenue is a measure of sales pace, not a measure of profit, cash flow, or valuation. Gross and net presentation can alter the top line without changing the total a customer pays or the provider’s share, while costs and cash needs require separate analysis. The cited reports do not establish that either company is profitable or provide audited current-period statements that settle the comparison.
