Research Findings

The investigation reveals extensive Palantir Technologies lobbying activity between 2019-2024, primarily focused on US policymakers regarding immigration enforcement, homeland security, and border security technologies. Palantir spent over $11.9 million on US lobbying in 2024-2025 alone, including $360,000 specifically on border security issues. The company secured major ICE contracts worth $145 million for immigration surveillance systems including ImmigrationOS. While this lobbying directly affects UK operations through the transatlantic intelligence-sharing relationship, the evidence shows Palantir's UK strategy relied more on high-level introductions (via Sir John Sawers and Peter Mandelson) than formal lobbying disclosures. Louis Mosley, Palantir's UK chief, has advocated for a 'common operating system' integrating UK government data, suggesting coordination between US immigration technology development and UK data integration ambitions. The company's position as the second-largest AI supplier to UK public sector demonstrates how US lobbying success on immigration technology translates into UK government influence.
