Checked 12 September 2026. Public research only. Sources are institutional accounts or authored policy statements, with their limits retained.
MIRI current roles: https://intelligence.org/team/ . Yudkowsky is listed under Leadership and Board. Malo Bourgon is CEO; Nate Soares is President. Earlier Singularity Institute name: https://intelligence.org/transparency/ . These are institutional roles, not proof of personal control over all linked organizations.
Contributor history: https://intelligence.org/topcontributors/ . The displayed update is 30 April 2026. Credits are cumulative and include matching leveraged; the recent category means some support in the preceding five years. Thiel and Alameda appear under past contributors. Do not allocate these totals to any specific current campaign.
Primary donation details: https://intelligence.org/2021/05/13/two-major-donations/ . Anonymous donor's MKR liquidation and spending limits are a distinct transaction; the issuer of the token was not named as the donor. Vitalik's separate ETH gift is included in historical support rather than added again to lifetime credits.
Correction essential to funding genealogy: https://intelligence.org/2020/04/27/miris-largest-grant-to-date/ . The proposed Ben Delo partnership was cancelled and other funders supplied the grant. Do not preserve a cancelled proposal as a completed payment.
Policy record: https://time.com/6266923/ai-eliezer-yudkowsky-open-letter-not-enough/ is a 2023 authored position advocating international restrictions on large AI training and willingness to enforce them against infrastructure, including military action. It does not establish enacted powers or a policy of executing researchers. The later MIRI treaty is a separate document/version; campaign notes contain its safeguards and operational limitations.
Advocacy adoption: https://controlai.org/blog/the-campaign promotes Yudkowsky/Soares's book. https://controlai.org/blog/briefing-70-lawmakers-on-ai invokes Yudkowsky's explanation of inferential distance. These support transmission of arguments and methods, not a funding or command edge.
Strategic differences: https://controlai.org/blog/prevent-asi-plan (20 April 2026) praises the book while explaining ControlAI's more repeatable campaign operations. https://controlai.org/designing-the-dip criticizes some evaluator and elite-placement strategies and notes Yudkowsky's shift toward public awareness. Institutional overlap does not erase these strategic differences.
Direct access: https://intelligence.org/2026/03/19/miri-newsletter-125/ explicitly records Yudkowsky and Soares briefing Sanders; links the official video https://www.youtube.com/watch?v=1oS35oWWl28 . Official upload metadata dates that video 4 March 2026. The full video was not watched in this pass. This supports briefing access, not authorship of later legislation.
Local scope: the inspected portable Editorial v2 dataset lacks a named Yudkowsky/MIRI entity profile, while local media-surge research contains MIRI treaty analysis. Correctly record this as an integration gap in that snapshot, not as an absence from all research.
Independent editorial challenge upheld the keystone assessment within the AI-risk/prohibition network, with boundaries on historical donor attribution, operational leadership, policymaker access versus drafting, and intellectual influence versus organizational control.
