Palantir is still using Anthropic’s Claude as Pentagon blacklist plays out, CEO Karp says

Palantir is still using Anthropic’s Claude as the artificial intelligence startup’s clash with the Pentagon plays out, CEO Alex Karp told CNBC Thursday.

“The Department of War is planning to phase out Anthropic; currently, it’s not phased out,” Karp told CNBC’s Seema Mody at Palantir’s AIPcon 9 in Maryland. “Our products are integrated with Anthropic, and in the future, it will probably be integrated with other large language models.”

The Department of Defense officially designated Anthropic a supply-chain risk last week, but is still using Claude models to support the war in Iran, as CNBC previously reported.

Anthropic sued the Trump administration on Monday to reverse the supply chain risk designation and is seeking a stay on the DOD action.

This is the first time that Palantir has commented since the Pentagon’s designation. Anthropic and Palantir partnered with Amazon Web Services to support the DOD in 2024.

Other defense tech companies have told employees to stop using Claude as the clash plays out, including Lockheed Martin.

Defense Department CTO Emil Michael told CNBC Thursday that it would take time for the government to transition away from Anthropic’s models.

“You can’t just rip out a system that’s deeply embedded overnight,” Michael told CNBC’s “Squawk Box.”
