Anthropic Hires Former Carnegie Endowment President and California Supreme Court Justice as Its First Chief Global Affairs Officer

Anthropic has appointed Mariano-Florentino (Tino) Cuéllar as its first Chief Global Affairs Officer — a hire that signals the company is moving from reactive policy engagement to a proactive, institutionalised approach to shaping how governments around the world govern AI.

Who Is Tino Cuéllar?

Cuéllar arrives at Anthropic with one of the most genuinely cross-domain CVs in AI policy. He most recently served as President of the Carnegie Endowment for International Peace, a 110-year-old independent research institution with scholars operating across 20 countries. Before that, he was a Justice of the Supreme Court of California — a role in which his written opinions addressed technology and privacy, international agreements, and separation-of-powers questions that increasingly intersect with AI governance.

His academic footprint at Stanford is equally substantial: he served as director of the Freeman Spogli Institute for International Studies, co-directed Stanford's Center for International Security and Cooperation, and founded the Stanford Cyber Initiative. He has served on the President's Intelligence Advisory Board, the US Department of State's Foreign Affairs Policy Board, and worked inside the White House and federal agencies across three presidential administrations. The National Academy of Sciences appointed him to its Committee on Responsible Computing Research. He also co-chaired the bipartisan Task Force on Nuclear Proliferation and American Security and co-led California's Frontier AI Working Group.

Cuéllar is currently the Cameron Schrier Family Professor at Stanford Law School — where he began teaching classes on artificial intelligence nearly a decade ago — and a Senior Fellow at Stanford's Institute for Human-Centered Artificial Intelligence.

Why This Role, Why Now

The Chief Global Affairs Officer title is new at Anthropic. The company is creating it specifically to formalise what has until now been more ad-hoc: structured engagement with governments, international bodies, and civil society on AI policy, safety standards, and the economic and security implications of frontier models. Cuéllar will lead policy, strategic international engagement, and government relationships worldwide.

"Policymakers in the US and around the world are increasingly realising that we are at a critical inflection point when it comes to how we govern and develop artificial intelligence," Cuéllar said in Anthropic's announcement. "Democracies must set the terms on which this technology advances, and there is no more consequential place to be shaping that work right now than Anthropic."

Daniela Amodei, Anthropic's President, framed the appointment in terms of institutional trust: "At all levels of government, the law, and academia, Tino has served with sound judgment and civic-mindedness, and we're looking forward to him putting these principles to work at Anthropic."

The Trust Connection

Cuéllar's relationship with Anthropic predates this appointment. He has served as a Trustee of Anthropic's Long-Term Benefit Trust since January 2026 — the governance structure Anthropic established to ensure the company's mission remains focused on long-term benefit to humanity. He has stepped down from the Trust to join the company in an executive capacity; the Trust will select a successor through its normal process.

That prior trusteeship is significant. It means Cuéllar has already operated inside Anthropic's governance framework and understands the company's safety-first philosophy at an institutional level — not as an outsider being briefed up but as someone who helped shape oversight from within.

Reading the Strategic Signal

The appointment reflects a broader pattern across the frontier AI industry. As governments accelerate AI legislation — from the EU AI Act's enforcement timelines to US executive actions and emerging bilateral AI frameworks — the companies building frontier models are building the institutional capacity to engage those processes rather than simply respond to them.

Anthropic's choice to hire a former Supreme Court Justice and Carnegie Endowment president — rather than a conventional tech lobbyist — is a deliberate positioning move. It signals that the company intends to engage regulators as a peer institution, bringing legal and policy credibility to conversations about liability, safety standards, and international AI governance that will define the industry's operating conditions for the next decade.
