Jack Clark

Jack Clark is a technology writer and AI policy leader who co-founded Anthropic. He studied English literature and creative writing at the University of East Anglia. Before working inside AI organizations, he reported on technology, including at Bloomberg, developing an interest in the practical and social consequences of advances in machine learning.

Clark joined OpenAI in 2016 and worked on policy and communication around AI research. He also created Import AI, a newsletter tracking technical developments and their implications. His work has included involvement with the AI Index and engagement with government and research institutions concerned with measuring and governing AI progress.

In 2021, he co-founded Anthropic with other former OpenAI colleagues. His role has focused on the relationship between increasingly capable systems and the wider world. That includes questions about policy, economic change, security, and the information public institutions need when making decisions about AI development and deployment.

In 2026, Anthropic named Clark its head of public benefit, leading the Anthropic Institute. The institute brings together work on societal consequences and preparedness as model capabilities grow. His contribution to AI is therefore primarily about accountability, analysis, and institutional communication: helping technical findings become information that policymakers and the public can use to understand possible benefits and risks.
