U.S. appeals court upholds Pentagon’s blacklisting of Anthropic
A U.S. appeals court has upheld a Pentagon order blacklisting AI startup Anthropic from military contracts due to national security concerns. Anthropic is currently reviewing its legal options following the ruling, which impacts its business reputation ahead of a planned IPO.
Why it matters
This case highlights the growing tension between national security interests and the rapid development of private AI companies seeking government partnerships.
A federal appeals court on Friday (September 25, 2026) declined to block a Defense Department order blacklisting Anthropic from military contracts and deeming the AI startup a national security risk.
The ruling from the U.S. Court of Appeals for the District of Columbia Circuit came in a lawsuit by Anthropic challenging its designation by the Pentagon as a national security supply chain risk, which the startup says has cost it billions of dollars in lost business and damaged its reputation ahead of a highly anticipated initial public offering.
Anthropic said in a statement that it respectfully disagrees with the decision but remains confident in its position and is considering its options, including further judicial review.
