Palantir Technologies (PLTR) surged 4.6% on Monday, April 14 following news that NATO closed a contract to deploy the Maven Smart System NATO (MSS NATO) technology, which is an artificial intelligence-based battlespace awareness platform created by U.S.-based software provider Palantir. The agreement represents a huge win for Palantir in European defense markets, expanding from its partnership with U.S. military forces to all of NATO.
This comes after an unpredictable couple of months for PLTR stock. After hitting new 52-week highs above $125 in early 2025, shares came under pressure as news emerged that President Donald Trump intended to slash the defense budget over the next several years.
