On September 9, 2026, OpenAI said Paul Christiano—ARC founder, former OpenAI alignment lead, and CAISI/NIST senior advisor—joins the OpenAI Foundation Board as a non-voting observer on the Group PBC board and the Foundation Safety and Security Committee with chair Zico Kolter.
TLDR
OpenAI on Wednesday, September 9, 2026 published “Paul Christiano joins OpenAI Foundation Board.” Non-voting observer on the OpenAI Group PBC board. Joins Foundation Safety and Security Committee with chair Zico Kolter. Background: CAISI/NIST Senior Tech Advisor (two administrations); founder ARC; led OpenAI alignment 2017–2021 (RLHF). Builds on prior Foundation recaps and CA+DE AG reviews. Leadership/governance lane, not a model.
Product-line de-dupe: not Astra (3), not Lightcap departure (Aug 11), not Rajic CRO (Aug 13).
Why this story matters
Christiano is the alignment brand OpenAI lost and is now borrowing back as a Foundation observer—after Critical Astra and the HF/DseWiki week. Watch: whether observer status can stop a run, or only write memos.
