From the speaker
- OpenAI communicated very little with the IMO
- prior to announcing their success
- In contrast
Our interpretation
- Very little means limited exchanges rather than sustained coordination over the model's participation and assessment.
- It does not mean no communication.
- The period ends with OpenAI's July 19, 2025 announcement. Month precision accommodates the sources' approximate dates for earlier contact; it does not include subsequent communication.
Counts as supported if: Accounts from participants or organizers describe limited prior exchanges, without substantive coordinated participation.
Counts as contradicted if: Correspondence or participant accounts establish extensive prior communication about participation, assessment, or announcement arrangements.
Retrospective: these criteria were written after the outcome was public.
Current assessment
Was it true for the period described?
Outcome: Supported
The dated evidence matches what the claim committed to, under the criteria frozen before grading.
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
OpenAI's own researcher described contact with one organizer before announcing the result. He separately acknowledged an earlier invitation that OpenAI declined. Together, these accounts support Marcus's ordinary claim of limited communication. They do not support a stronger claim of no contact.
Limitations
- The conclusion relies on participant accounts rather than a complete correspondence record.
- This verdict does not decide the separate dispute about announcement timing or an embargo.
Evidence (2 items)
Supports the claim: Noam Brown, OpenAI, via X,
one organizer
Why it matters here: Brown describes a limited notification to one organizer before the announcement. This directly supports limited prior communication.

Context only: Noam Brown, OpenAI, via X,
the IMO emailed us
Why it matters here: Brown also acknowledges an earlier invitation, which his full post says OpenAI declined. This rules out interpreting the claim as no contact at all, while remaining consistent with limited communication.
