Palantir Technologies Inc. (NASDAQ:PLTR) and Armada today announced a partnership to deliver sovereign AI on infrastructure manufactured in the United States and allied nations, with Palantir naming Armada its Inaugural Certified Modular Data Center Partner. The joint offering combines Palantir's Sovereign AI Operating System with Armada's infrastructure layer: modular data centers, the Armada Platform that keeps every deployment under the customer's control, and the Sovereign AI Grid that connects deployments into a resilient distributed system. Enterprises and governments gain the ability to run open-weight models on compute, data, and physical infrastructure they own and control outright, deployed in months rather than years.
