When an AI lab brings a former supreme court justice on board, that’s not your average hire. On August 4, Anthropic announced that Mariano-Florentino Cuéllar — everyone calls him Tino — is joining as its first Chief Global Affairs Officer. He’ll lead the company’s entire policy, government, and international engagement work.
Who is Tino Cuéllar?
His résumé reads like three careers rolled into one. Most recently he was president of the Carnegie Endowment for International Peace — one of the most respected global policy think tanks, with scholars in 20 countries. Before that he was a Justice on the Supreme Court of California, ruling on technology, privacy, and the separation of powers, among other things. And before that he worked in the White House across three different US administrations.
The AI connection isn’t new either. Cuéllar started teaching classes on artificial intelligence at Stanford Law School nearly a decade ago. He co-led California’s Frontier AI working group — the very group advising the state on how to regulate AI. And since January 2026 he sat on Anthropic’s Long-Term Benefit Trust, the body meant to watch over the company’s long-term direction. He stepped down from that seat to take the job.
Why it matters
Anthropic has spent months positioning itself as the lab that doesn’t just tolerate regulation but actively wants to help shape it. The timing fits: California just brought its AI Transparency Act into force, the White House let a deadline for a frontier AI framework slip, and governments everywhere are wrestling with the question of who actually sets the rules for this technology.
Cuéllar puts it bluntly: democracies must set the terms on which AI advances. And right now, he says, there’s no more consequential place to shape that work than Anthropic. That’s confident — and it says a lot about how the company sees itself.
My take
What surprises me isn’t that Anthropic is beefing up its policy shop — it’s who they picked. This isn’t a Beltway lobbyist. It’s someone with a judicial past and academic standing. The signal is clear: Anthropic doesn’t want to approach governments as a supplicant. It wants to talk as an equal — about safety, about competition, about who ultimately benefits from this technology.
Whether that pays off depends less on Cuéllar’s title than on substance. But a hire like this shows the AI race is no longer decided only in the models — it’s decided in parliaments, courts, and ministries. And that’s where Anthropic now intends to play.
