From the speaker
- According to the documents viewed by this newsletter
- OpenAI spent $5.02 billion
- on inference alone with Microsoft Azure
- in the first half of Calendar Year CY2025
Our interpretation
- The target period is January 1 through June 30, 2025.
- Assess the spending amount, not merely whether Zitron reported seeing documents. The document attribution is a sourcing qualification, not a conditional forecast.
- Read spending as charges incurred for Azure inference during the period, separate from training and revenue-sharing payments. The wording does not establish that every charge was settled in cash.
- Treat $5.02 billion as rounded to the nearest $0.01 billion.
- Use company_reported because the claim purports to reproduce company financial records. This classification does not authenticate those records or establish GAAP treatment.
- Read the amount as gross inference spending before offsetting separate revenue flows between the companies.
Counts as supported if: Authenticated company records or independently corroborated reporting establish that OpenAI incurred Azure inference charges during January–June 2025 that round to US$5.02 billion, with the accounting treatment identified.
Counts as contradicted if: Comparable records establish a different January–June 2025 Azure inference total outside the stated rounding precision, or demonstrate that the claimed total includes material spending outside the specified service or period.
Retrospective: these criteria were written after the outcome was public.
Current assessment
Was it true for the period described?
Outcome: Unresolved
The record was checked, and the evidence available by the cutoff does not settle it.
Scored on a plain reading. The speaker named no measure for this claim, so it was judged on the reading an informed reader would take, stated below under our interpretation. Both reviews had to find that reading fair.

Rationale
The search did not locate accessible records or independent verification establishing OpenAI's Azure inference spending for January–June 2025. Coverage repeating Zitron's figures does not independently confirm them. The reported qualification about incomplete accounting also supplies no corrected H1 amount. The evidence therefore establishes neither support nor contradiction.
Limitations
- The underlying financial records were unavailable for inspection.
- Relevant original reporting was inaccessible through read_page.
- Failure to verify the amount is not evidence that Zitron's report was false.
Evidence (1 item)
Context only: The Register,
Another source familiar with OpenAI suggested to the FT that the figures offered an incomplete accounting of the two company's dealings.
Why it matters here: This is a material qualification reported through another outlet, not a corrected measurement of H1 spending. It cannot establish that the specified inference total is false.

What would settle it
Authenticated Microsoft or OpenAI records, or independent verification of them, showing the January–June 2025 Azure inference total and explaining credits, offsets, and the distinction between charges incurred and cash paid.
