Palantir jumps 4% on Nvidia sovereign AI deal, lifting software stocks

Palantir Technologies rose more than 4% after partnering with Nvidia to bring open-source AI models to US government agencies, sparking a broad rally in AI application software stocks.

Palantir Technologies rose more than 4% after partnering with Nvidia to run its Nemotron open-source AI models in sovereign environments for US government agencies and critical infrastructure operators, addressing a key security concern that has limited AI adoption in classified settings.

"Combining Palantir infrastructure with NVIDIA's AI and Nemotron models will allow the U.S. government to unleash the full power of LLMs while removing the underlying security risks and rational concerns around proprietary insights migrating into the weights of closed models," Alex Karp, co-founder and chief executive officer of Palantir, said.

The joint offering combines Nvidia's AI platform — including its Nemotron open models and NIM microservices — with Palantir's AIP, Ontology, Foundry and Apollo platforms. Key capabilities include explicit data authorization, secure perimeter enforcement, customer-specific isolation and full auditability, according to the companies. The system collects user telemetry and trace data to continuously post-train and align models for specific operational tasks, creating a self-improving feedback loop tailored to each agency's mission.

The broader AI software sector followed Palantir higher. Roblox surged nearly 12%, Applovin rose 5%, ServiceNow gained 4% and Shopify added 3%, reflecting broad investor appetite for AI application software after the partnership announcement.

How the Sovereign AI Engine Works

The intelligent engine allows government agencies to deploy base and customized Nemotron models in classified, air-gapped and other sensitive environments. Nvidia Chief Executive Officer Jensen Huang called open-source AI "foundational to national security, public safety and U.S. technology leadership." The offering includes deployment engineering for sensitive environments, context engineering to optimize model behavior around operational use, and model engineering that lets agencies change model weights based on proprietary data and mission outcomes. Nvidia's Nemotron open models deliver frontier capabilities for specialized workloads while enabling organizations to retain control of their data, intellectual property and AI systems, the companies said.

What's at Stake for Investors

Palantir shares have been sensitive to government AI contract news, with the company positioning its platforms as essential infrastructure for national security. The Nvidia partnership gives Palantir a differentiated offering in the sovereign AI segment, where competitors including Microsoft and Amazon Web Services also offer government cloud solutions but with different approaches to model openness and data control. For Nvidia, the deal extends its reach beyond enterprise and consumer AI into the government sector, where long-term contracts and high security requirements create sticky revenue streams. Palantir trades at roughly 55 times forward earnings, reflecting the premium investors place on its government AI exposure, while Nvidia trades at about 30 times forward earnings.
