From the speaker
- Through September
- Microsoft’s revenue share payments totalled $865.9 million
- OpenAI’s revenues are at least $4.329 billion
Our interpretation
- Context fixes the period as January through September 2025, not Microsoft's fiscal year.
- Assess the payment total and the implied revenue floor together, using the contextual 20% rate.
- Preserve the lower-bound wording. Higher actual revenue would be compatible with the claim.
- Accounting basis is estimate because the amounts are journalist-reported from nonpublic documents. Gross versus net treatment is unspecified.
Counts as supported if: Independent records establish $865.9 million in period-attributable revenue share through September 2025, and the applicable percentage, revenue base, and settlement treatment establish a floor of at least $4.329 billion.
Counts as contradicted if: Comparable records establish a materially different payment total, or the agreement and accounting treatment show that the stated floor does not follow.
Retrospective: these criteria were written after the outcome was public.
Current assessment
Was it true for the period described?
Outcome: Unresolved

Rationale
The official announcement confirms a revenue-sharing arrangement but does not disclose the earlier payment amounts or percentage. Accessible reports of the total trace to Zitron. Dividing his stated amount by 20% yields a floor close to his figure, but correct conditional arithmetic cannot authenticate the input. Neither support nor contradiction is established.
Limitations
- The cited primary announcement concerns a later agreement update.
- No ledger, payment reconciliation, or complete contract was obtained.
Evidence (1 item)
Context only: OpenAI,
The revenue share agreement remains until the expert panel verifies AGI, though payments will be made over a longer period of time.
Why it matters here: This confirms the arrangement's existence, not the January–September payment total or rate. The later payment provision cannot establish how the earlier periods were accounted for.

- Company disclosure: the company describing itself, not an independent finding
- Arithmetic
- 865.9 / 0.20 = 4329.5 million. (inputs: Claim-stated January–September payment: $865.9 million, independently unverified.; Claim-context revenue-share rate: 20%, not disclosed in this company announcement.; The claim's $4.329 billion minimum is $0.5 million below the quotient. This is conditional arithmetic, not verification of the inputs.)

What would settle it
Authenticated January–September 2025 payment or accrual records, together with the applicable revenue-share terms and reciprocal-offset reconciliation.
