Palantir Technologies cooperation with Poland sparks protests

Activists and civil society groups in Warsaw have organized protests against a potential partnership between the Polish Ministry of National Defense and the American software company Palantir Technologies. The initiative, led by the group Nasze Dane, raised concerns regarding the security and privacy of sensitive military data.

Protesters delivered an open letter signed by over 3,000 people to the Presidential Palace, calling on President Karol Nawrocki to mandate an independent legal and technical audit of the agreement. Demonstrators are seeking transparency regarding who will access military data, where it will be stored, and the extent of Poland's control over the technology.

Recent developments include a memorandum of understanding signed between the Cyber Defense Command and Palantir in December 2024, as well as a letter of intent signed in October 2025 by Deputy Prime Minister and Defense Minister Wladyslaw Kosiniak-Kamysz and Palantir CEO Alexander Karp. The cooperation aims to explore the use of the Maven Smart System, an AI-powered platform designed to support military analysis and planning by aggregating data from various sources.
