Peter Thiel-Backed Palantir Stock Rallies After NATO Acquires Its AI-Enabled Warfighting System

Shares of Palantir Technologies Inc. (PLTR) soared nearly 6% on Monday morning after the NATO Communications and Information Agency (NCIA) said the agency and Palantir have finalized the acquisition of an AI-enabled warfighting system.

Palantir is chaired by noted investor and Donald Trump-backer Peter Thiel, one of Facebook's earliest investors.

Palantir’s Maven Smart System NATO (MSS NATO) will be employed within NATO’s Allied Command Operations (ACO), enabling a significant advancement in the modernization of its warfighting capabilities.

The NCIA said that the MSS NATO capability empowers commanders and warfighters to leverage cutting-edge artificial intelligence (AI) safely and securely in core military operations.

Through MSS NATO, the Supreme Headquarters Allied Powers Europe (SHAPE) is also looking to accelerate the adoption of novel capabilities like new, emerging AI models and modeling and simulation.

The development comes as Trump has threatened to stop protecting Europe if countries do not spend more on defense while rivals like China are increasing their AI-powered military capabilities.

The NCIA said that the procurement of MSS NATO was “one of the most expeditious in NATO’s history, taking only six months from outlining the requirement to acquiring the system.”

NATO’s Allied Command Operations (ACO) is expected to start using the new system within the next 30 days.

SHAPE Chief of Staff General Markus Laubenthal said that Maven Smart System NATO enables the Alliance to leverage complex data, accelerate decision-making, and add true operational value.

PLTR shares have gained over 24% in 2025 and over 326% in the past 12 months.
