Palantir Technologies has named Nebius Group as its preferred sovereign AI infrastructure partner for commercial customers, a deal that stitches together Nebius’ compute muscle with Palantir’s enterprise software stack. The announcement was made on September 8.

The partnership integrates Nebius’ compute and inference capabilities directly within Palantir’s enterprise perimeter. That perimeter includes AIP, Ontology, Foundry, and Apollo, the suite of products Palantir has spent years building into the operating system for data-heavy organizations.

In practical terms, customers can deploy open AI models and fine-tune them using their own proprietary data without handing control of their compute, models, or data to a third party.

Nebius, which trades on the Nasdaq under the ticker NBIS, brings modular data centers located at secure power sites to the arrangement. These purpose-built environments are designed to resolve the compute bottlenecks that have become a limiting factor in enterprise AI adoption.

Palantir CEO Alex Karp emphasized the partnership’s sovereignty focus, stating it enables organizations to “run your own AI models under conditions you control.”
