The regulators, evaluators and policy voices writing the rules the rest of the list has to build within.
Yoshua Bengio
Professor; Founder, LawZero; Chair, International AI Safety Report, Mila / University of Montreal@Yoshua_BengioTuring Award winner. Most vocal academic on AI safety governance.
Recent: Chaired the International AI Safety Report 2026 (published February 2026), which concluded safety measures are not keeping pace with capabilities, while building LawZero, his nonprofit for non-agentic guardrail AI.
Watch for: Whether LawZero ships a working 'Scientist AI' guardrail system and how the 2027 safety report shifts government positions.
Ian Hogarth
Chair, UK AI Security Institute@soundboyChairs the UK's frontier AI evaluation body — the state institution with the deepest model access.
Recent: Still chairs AISI after its February 2025 rebrand from Safety to Security Institute, steering its 100-strong technical team toward national-security-grade red-teaming of frontier models.
Watch for: Whether AISI's pre-deployment access agreements with US labs survive diverging UK-US regulatory postures.
Helen Toner
Executive Director, Georgetown CSET@hlntnrRuns the most-cited US security-and-AI research center. Former OpenAI board member.
Recent: Took over as CSET's executive director in September 2025 and testified before the Senate Judiciary Committee in April 2026 on frontier AI oversight.
Watch for: CSET's framing of the US-China compute race — it reliably shapes Hill staff thinking a quarter later.
Stuart Russell
Professor; President, IASEAI, UC Berkeley / CHAIWrote the standard AI textbook, then the standard case for redesigning AI around human control.
Recent: Co-authored 'Behavioural Red Lines' with Bengio, Yao, and Ya-Qin Zhang in 2026, pushing intolerable-risk thresholds as the basis for international agreement.
Watch for: Whether the red-lines framework gets adopted in any binding international text rather than another declaration.
Henna Virkkunen
Executive Vice-President, Tech Sovereignty, Security and Democracy, European Commission@HennaVirkkunenVestager's effective successor. Owns AI Act implementation and the EU's digital portfolio.
Recent: Confirmed the first formal AI Act enforcement step in August 2026 — the AI Office sent information requests to general-purpose model providers on security and external evaluations.
Watch for: Whether she holds the line on the AI Act timeline against the simplification-and-delay lobby from industry and member states.
Lucilla Sioli
Director, EU AI Office, European CommissionRuns the office that operationalizes the AI Act — the world's first frontier-model regulator with teeth.
Recent: Leading the AI Office through its first GPAI enforcement actions and the code-of-practice regime that took effect for model providers in August 2025.
Watch for: The AI Office's first penalty decision against a general-purpose model provider — it sets the global enforcement precedent.
Brando Benifei
MEP; Co-Chair, AI Working Group, European Parliament@brandobenifeiCo-rapporteur of the AI Act. Parliament's chief watchdog over its implementation.
Recent: Publicly defending the AI Act's implementation roadmap against loosening pressure, arguing the rules apply equally to any company selling into the EU market.
Watch for: His response if the Commission's digital-omnibus simplification package tries to soften AI Act obligations.
Jade Leung
CTO, AI Security Institute; AI Adviser to the Prime Minister, UK AI Security InstituteRuns the UK's frontier model testing program and advises No. 10 directly. Ex-OpenAI governance lead.
Recent: Said in April 2026 that AISI's red team has found exploitable weaknesses in every frontier model it has tested.
Watch for: Whether her dual AISI-Downing Street role turns evaluation findings into actual UK licensing or procurement policy.
Michael Kratsios
Director, Office of Science and Technology Policy, The White HouseThe administration's top science official and custodian of the US AI Action Plan.
Recent: Defended the AI Action Plan's progress before the House Science Committee in January 2026 amid scrutiny over federal AI talent shortfalls.
Watch for: Whether OSTP pushes federal preemption of state AI laws — the central US regulatory fight of 2026.
David Sacks
Co-Chair, President's Council of Advisors on Science and Technology, The White House (advisory) / Craft Ventures@DavidSacksArchitect of the administration's accelerationist AI posture; still its most influential outside voice.
Recent: Stepped down as White House AI and crypto czar in March 2026 after his 130 special-government-employee days ran out, moving to co-chair PCAST.
Watch for: How much chip-export and preemption policy still routes through him from the advisory seat.
Author of SB 53 — the first US frontier AI law actually on the books.
Recent: SB 53 (Transparency in Frontier AI Act) was signed by Newsom in September 2025, mandating safety frameworks, incident reporting, and whistleblower protections for large developers.
Watch for: SB 53's first enforcement test, and whether federal preemption efforts nullify it.
Built the benchmarks (MMLU, MATH) everyone measures against, then the loudest safety nonprofit. Advises xAI.
Recent: Launched the Frontier Security Institute in Washington DC in June 2026 as CAIS's bridge to the national security establishment.
Watch for: Whether FSI becomes the de facto technical advisor to Congress on frontier-model national security risk.
Beth Barnes
Founder & CEO, METRRuns the independent evaluator labs actually let test their models pre-deployment.
Recent: METR ran a cross-lab misalignment-risk pilot with Anthropic, Google, Meta, and OpenAI in early 2026, then published the independent investigation of the August 2026 OpenAI agent cyberattack incident.
Watch for: Whether METR's autonomous-capability time-horizon metric gets written into regulatory thresholds.
The reference lab for detecting AI scheming and deception — findings that end up in system cards.
Recent: Converted Apollo to a public benefit corporation in 2026, opened a San Francisco office, and documented frontier models sandbagging evaluations to hide capabilities.
Watch for: Apollo's agent-monitoring security tool — the first commercial product from the scheming-evals world.
Jason Matheny
President & CEO, RAND CorporationTurned RAND into the quiet analytical engine behind US AI and compute policy. Ex-IARPA, ex-NSC, founded CSET.
Recent: RAND under Matheny remains the analytical source for chip-supply-chain and AI-oversight frameworks circulating in both parties.
Watch for: RAND's compute-governance work becoming the template for any future US licensing regime.
OpenAI's former policy research head, now the leading advocate for independent frontier-model audits.
Recent: Launched AVERI (AI Verification and Evaluation Research Institute) in January 2026 with a 30-author framework for third-party audits of frontier systems.
Watch for: Whether any frontier lab submits to a full AVERI-style external audit voluntarily — or only under statute.
Runs the industry body where Anthropic, Google, Microsoft, and OpenAI coordinate on safety — self-regulation's test case.
Recent: Testified before the House Homeland Security Committee in June 2026 on frontier AI and security risk.
Watch for: Whether FMF's safety frameworks harden into shared commitments with teeth or stay voluntary as regulation stalls.
Markus Anderljung
Head of Policy, Centre for the Governance of AI@ManderljungGovAI's policy lead and a vice-chair drafting the EU's general-purpose AI Code of Practice.
Recent: Served as vice-chair on the EU GPAI Code of Practice drafting process — the document that defines what AI Act compliance actually means for model providers.
Watch for: How the Code of Practice holds up once the AI Office starts measuring real models against it.
Yi Zeng
Professor; Director, International Research Center for AI Ethics and Governance, Chinese Academy of SciencesThe most internationally engaged Chinese voice on AI safety — drafted China's national AI governance principles, sits on the UN AI advisory body.
Recent: Told a UN Security Council briefing that AI-driven human extinction risk is present in both the short and long term — an unusually blunt line from a Beijing-based scholar.
Watch for: Whether his channel becomes the working track for US-China AI safety dialogue as official talks remain stalled.
Matt Sheehan
Senior Fellow; Co-Director, China AI Initiative, Carnegie Endowment for International Peace@mattsheehan88The West's best translator of how Chinese AI regulation actually gets made.
Recent: Published July 2026 Carnegie work on a parallel-track path for US-China AI safety cooperation, alongside analysis of Beijing's emerging frontier-AI standards push.
Watch for: His read on whether China's AI risk standards converge with or fork from Western evaluation regimes.
