Anthropic names Tino Cuellar as first Chief Global Affairs Officer

Anthropic created a Chief Global Affairs Officer position and named Mariano-Florentino (Tino) Cuellar to fill it on August 4, 2026. The hire gives the company its first dedicated executive for U.S. government relations, international policy engagement, and AI governance work across governments and civil society organizations.

Who Cuellar is

Cuellar served as a Justice of the California Supreme Court and as President of the Carnegie Endowment for International Peace, one of the oldest U.S. foreign-policy think tanks. His government record spans three presidential administrations, including White House and federal agency roles, membership on the President's Intelligence Advisory Board, and a seat on the State Department's Foreign Affairs Policy Board, per Anthropic's announcement.

At Stanford, he directed the Freeman Spogli Institute for International Studies, co-directed the Center for International Security and Cooperation, and led the Stanford Cyber Initiative. He also co-led California's Frontier AI Working Group, a state-level body that produced binding recommendations on the oversight of advanced AI systems, and held a faculty appointment at Stanford Law School.

Cuellar had been a member of Anthropic's Long-Term Benefit Trust since January 2026 and stepped down from that role upon accepting the executive appointment.

What the role covers

The Chief Global Affairs Officer function is new inside Anthropic. Per the company's announcement, Cuellar will shape AI governance policy, advance what Anthropic describes as "democratic influence on AI development," and build direct relationships with governments and civil society internationally.

Cuellar stated: "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."

Why it matters

The appointment signals that Anthropic is treating government engagement as a structural priority, moving it from the legal function into the C-suite. Creating a dedicated C-suite role and filling it with a former state supreme court justice who has worked inside three presidential administrations positions the company with standing in both domestic regulation debates and international AI governance discussions.

The timing reflects pressure on frontier AI labs from U.S. federal regulators and the White House. Cuellar's intelligence-board experience and his prior work co-leading California's frontier AI working group give him a specific profile for federal engagement that extends beyond standard lobbying operations.

For AI-tool operators tracking how safety-focused labs manage regulatory risk, the creation of this role is a structural signal: Anthropic is betting that proactive policy engagement is a competitive and operational necessity.

What to watch next

Cuellar's first public policy statements or congressional testimony will indicate how Anthropic intends to engage on pending federal AI legislation. His co-leadership of California's Frontier AI Working Group also suggests involvement in state-level regulatory processes, which have gained legislative traction since 2024.
