The intersection of artificial intelligence and military power is generating some of the most consequential — and least transparent — policy battles in Washington. Defense AI spending is projected to exceed $18 billion in fiscal year 2027, and the companies competing for those contracts are spending heavily to shape the rules. Palantir Technologies, the data analytics firm co-founded by Peter Thiel, leads the pack with over $8 million in total federal lobbying spend focused heavily on defense and intelligence AI applications.
The Pentagon's adoption of AI has accelerated dramatically. The Replicator initiative, launched in 2023 to field autonomous drones and systems at scale, has awarded contracts worth over $2 billion. Project Maven, the controversial AI surveillance program that prompted a Google employee revolt in 2018, has expanded under new contractors. The Department of Defense's Chief Digital and AI Office (CDAO) now oversees an AI portfolio spanning logistics, intelligence analysis, predictive maintenance, and — most controversially — autonomous weapons systems.
Palantir's lobbying strategy offers a window into how defense AI companies operate in Washington. The company employs lobbyists from six firms, including former senior Pentagon officials and ex-congressional defense committee staffers. Its lobbying disclosures reference AI-related provisions in the National Defense Authorization Act (NDAA), autonomous systems policy, and intelligence community AI procurement.

Beyond Palantir, the defense AI lobbying landscape includes traditional primes and newcomers alike. Lockheed Martin, Northrop Grumman, and Raytheon (RTX) have all expanded their AI lobbying as autonomous weapons and AI-enabled command systems become central to defense strategy. Newer entrants like Anduril Industries (founded by Palmer Luckey), Shield AI, and Rebellion Defense are spending millions to challenge incumbent contractors for AI-specific programs. Combined, defense-focused AI companies spent over $31 million on federal lobbying in 2025.
The policy debate centers on autonomy and accountability. The Department of Defense Directive 3000.09 requires a human in the loop for lethal autonomous weapons, but critics argue the directive is outdated and its definitions are too vague to constrain current AI capabilities. Congress has held hearings on updating the directive, with testimony from military officials, AI researchers, and — notably — the companies building the systems. The AI Now Institute and Human Rights Watch have called for binding international regulation of autonomous weapons, while industry groups argue that restricting military AI would cede strategic advantage to China and Russia.
Campaign contributions from defense AI companies flow disproportionately to members of the Armed Services and Intelligence committees. Palantir's PAC contributed to 47 federal candidates in the 2024 cycle, with 68% going to Republicans. The company's contributions track closely with committee assignments relevant to its business interests. This pattern — targeted spending on lawmakers with direct oversight authority — is standard practice in defense lobbying but raises questions about whether AI weapons policy is being shaped by national security considerations or commercial ones.
