Palantir faces the difficult task of excising Anthropic’s Claude from a key military software product after a government directive barred agencies and their contractors from working with the AI lab. The affected product, Maven Smart Systems, provides intelligence analysis and targeting workflows to military users and incorporates multiple prompts and processes developed with Claude, according to people familiar with the matter.
U.S. authorities recently ordered that government entities stop using Anthropic following a dispute between the Pentagon and the AI company over whether Anthropic’s safety policies could limit certain military applications, including autonomous weaponry and surveillance. As a result of that directive, Palantir, which holds Maven-related contracts with the Defense Department and other U.S. national security agencies with a potential value in excess of $1 billion, will be compelled to substitute Claude with an alternate AI model and rebuild affected sections of the software, one source said.
How long the replacement and rebuilding process will take is not known. Defense Secretary Pete Hegseth has indicated the change should be immediate, saying: "Effective immediately, no contractor, supplier or partner that does business with the United States military may conduct any commercial activity" with Anthropic. The Pentagon, Anthropic and Palantir declined to comment.
Palantir’s chief executive voiced criticism of tech companies involved in debates around AI and national security without naming Anthropic. He argued at a defense technology conference in Washington that Silicon Valley firms that claim AI will displace white-collar work while also opposing military uses of the technology risk pushing the United States toward "the nationalization of our technology," according to his remarks posted on X.
The presence of Anthropic inside Maven highlights the practical and potentially expensive problem for the Pentagon, other federal agencies and U.S. companies that must unwind relationships with a single AI provider now embedded in both public sector systems and private-sector supply chains. Legal counsel specializing in government contracting and technology said defense contractors are expected to comply with the Pentagon’s order by removing Anthropic’s tools from their systems, even though the administration’s ban could face judicial challenges.
Maven is the Pentagon’s flagship artificial intelligence program. It is designed to aggregate data from numerous sources to flag military points of interest and accelerate intelligence analysis and targeting decisions. The system has been involved in recent U.S. military operations. It could not be immediately determined whether Maven was used in the January operation in Venezuela that resulted in the capture of former President Nicolas Maduro, or whether it played a role in the recent strikes on Iran.
Palantir’s software has become a central element in the Pentagon’s push to fold artificial intelligence into military operations. That role has elevated the company from a specialized intelligence contractor to a core supplier for defense modernization efforts, a shift that coincided with a market valuation of about $350 billion.
In the near term, Palantir must identify a replacement AI model compatible with Maven’s workflows, modify prompt structures and rebuild any integrations that depend on Claude. The technical work will involve both reengineering software components and validating that new models meet operational and safety requirements imposed by defense customers.
The sequence of actions by other defense suppliers is likely to mirror Palantir’s challenge. Attorneys working in government contracting and technology expect major contractors to purge Anthropic tools from their supply chains and systems to align with the Pentagon’s directive.
Until the necessary changes are completed, questions remain about continuity of service, potential schedule disruptions on classified programs and the broader implications for firms that have integrated Anthropic’s code into mission-critical applications.
Palantir’s ability to carry out the required transition, the timetable for doing so and the wider impact on defense procurement and contractor operations are all uncertain at this stage. The Pentagon, Anthropic and Palantir did not provide public comment on the technical details or the expected duration of the remediation work.
