Artificial intelligence is reshaping economies, societies, and the conduct of war. As governments race to harness it, their choices about military AI, governance, and sovereign capability will shape the balance of power between democracies and authoritarian states. This hub follows the policy frontier of artificial intelligence: the rise of military AI on the battlefield, the pursuit of sovereign AI and secure compute, AI governance and the rules that will constrain the technology, and the China AI challenge as Beijing races on frontier models. Fellows and analysts examine how AI intersects with defense, semiconductors, and national security, what sound AI governance looks like, and how the China AI contest reshapes strategy. Explore expert analysis and commentary on artificial intelligence and military power, sovereign AI, AI governance, and the technology competition defining the coming decade.
