Who is Tino Cuéllar?

He is a former justice of the Supreme Court of California and, until this appointment, president of the Carnegie Endowment for International Peace . He has also advised three US presidential administrations on foreign and security policy.

What will Cuéllar do at Anthropic?

As Chief Global Affairs Officer — a newly created role — he will lead Anthropic’s policy work, international engagement and government relationships, reporting to company president Daniela Amodei.

Why is Anthropic creating this role now?

The hire follows the Pentagon blacklisting some of Anthropic’s technology and a brief federal export-control directive that halted overseas sales of its top models earlier this year — friction that has pushed the company to invest more heavily in government relations.

Is this Cuéllar's first involvement with Anthropic?

No. He joined Anthropic’s Long-Term Benefit Trust, the independent body overseeing the company’s mission, as a trustee in January 2026 before moving into this operating role.

Anthropic Names Tino Cuéllar as First Chief Global Affairs Officer

Anthropic named Mariano-Florentino “Tino” Cuéllar as its first Chief Global Affairs Officer on August 4, putting him in charge of policy work, international engagement and government relationships as the company works through a run of friction in Washington, according to a company announcement.

Cuéllar arrives from the Carnegie Endowment for International Peace, where he recently stepped down as president. He previously served as a justice of the Supreme Court of California, sat on the President’s Intelligence Advisory Board and the State Department’s Foreign Affairs Policy Board, and has advised three US presidential administrations, Anthropic said. He is taking a leave of absence from his professorship at Stanford Law School, where he also holds a senior fellowship at the Stanford Institute for Human-Centered Artificial Intelligence.

The appointment follows a brief stint on Anthropic’s Long-Term Benefit Trust, the independent body that oversees the company’s mission. Cuéllar joined the trust only in January before moving into this new operating role, alongside the trust’s other recent addition, former Federal Reserve chair Ben Bernanke.

A rockier stretch of government relations

The hire lands as Anthropic works through a harder-than-usual patch with Washington. The Pentagon blacklisted some of the company’s technology earlier this year, and a brief federal export-control directive temporarily halted sales of its top-tier models abroad — a disruption serious enough that Austria lobbied the EU to host Anthropic as an alternative base. Anthropic and OpenAI have also both pushed federal lobbying spending to record levels this year, according to public disclosures.

Cuéllar will be based at Anthropic’s San Francisco headquarters and report to company president Daniela Amodei. “Tino has spent his career helping public institutions respond to times of change with thoughtfulness and pragmatism,” Amodei said in the announcement.

Cuéllar described the move as a chance to help shape how democratic governments respond to advanced AI. “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,” he said.
