Palantir Technologies and Anduril will develop software for the United States Golden Dome antimissile shield program. Palantir shares gained 2.51% following the announcement. The stock closed at $158.67 on March 25, 2026.
The defense contract served as the primary catalyst for the stock's rebound from a previous decline. Earlier in the week, the Pentagon designated Palantir's Maven AI system as an official program of record.
This designation ensures long-term funding for the AI system. It also facilitates deeper integration of Palantir technology within the U.S. military.
