Palantir Designates Nebius as Preferred Sovereign AI Infrastructure Partner
On September 8, 2026, Palantir Technologies and Nebius Group announced a strategic partnership in which Palantir designated Nebius its preferred sovereign AI infrastructure partner. Under the agreement, Palantir will integrate Nebius compute and inference endpoints within the Palantir enterprise perimeter, allowing eligible commercial customers to access Nebius's infrastructure while maintaining control over their data, models, and compute resources.
The companies will collaborate to accelerate deployment of new compute capacity to Palantir customers through modular data-center deployments at sites with existing power infrastructure, avoiding the need for new power installations before capacity comes online. Palantir selected Nebius because the provider was built for AI from the ground up rather than adapted from general-purpose computing, with infrastructure and software designed together for demanding AI workloads. Critically, Nebius can integrate directly into Palantir's Sovereign AI Operating System—a capability Palantir described as rare among providers.
The Sovereign AI Operating System rests on four integrated platforms: AIP, Ontology, Foundry, and Apollo. According to Palantir's documentation, Apollo is the continuous delivery platform managing underlying infrastructure and orchestrating zero-downtime upgrades. Foundry provides core data operations capabilities including data management, logic authoring, Ontology development, analytics, and workflow tools. AIP is the generative AI layer, offering secure connectivity to large language models, development toolkits for agents and automations, AI-enabled applications, and production governance frameworks. The integrated architecture functions as an enterprise operating system with a unified security model spanning infrastructure, platform, and enterprise layers, employing zero-trust principles at the infrastructure level and role-based, marking-based, and purpose-based access controls at the platform level.
Eligible Palantir customers will be able to deploy open models on Nebius infrastructure and continuously refine them using proprietary data for specific domains, enabling organizations to build domain-specific AI that outperforms general-purpose closed models while retaining control of both data and resulting models. The partnership reflects a shared conviction that open models combined with customer data create superior domain intelligence and stronger security posture.
"Nebius' compute infrastructure powers your ability to run your own AI models under conditions you control," said Alex Karp, co-founder and CEO of Palantir. "Our ontology and their infrastructure will undergird the sovereignty our partners are demanding."
Arkady Volozh, founder and CEO of Nebius, added: "Organizations need both the performance of large-scale AI infrastructure and control over their data and models. Together with Palantir, we are bringing this to commercial clients enabling them to run their optimized open models on trusted infrastructure."
Nebius, listed on Nasdaq and headquartered in Amsterdam, is building a full-stack AI cloud platform spanning data and model training through production deployment. The platform serves startups and enterprises developing AI products, agents, and services. The partnership enables commercial organizations without prior access to sovereign infrastructure options to run their own models on trusted, controlled systems.
