Federal Court Rejects Anthropic Challenge to National Security Label

A ruling that keeps the Trump administration's supply-chain risk designation legally intact, while a separate injunction continues to limit its immediate operational effect, creates an unresolved...

A federal appeals court on September 25, 2026, rejected artificial intelligence company Anthropic PBC's legal challenge to the Trump administration's designation of the firm as a supply-chain risk to U.S. National security, according to reporting by Bloomberg.

The court's decision leaves the national security label in place as a matter of law. However, Bloomberg reported that an earlier court ruling that had lifted an operational ban on Anthropic appears to remain in effect for the time being, meaning the company continues to operate under that prior judicial protection even as the underlying designation stands.

The Trump administration's designation of Anthropic as a supply-chain risk is rooted in executive authority over national security and federal procurement. The specific statutory or executive order basis for the classification was not identified in the available source material. The document that would clarify the precise legal authority is the administration's formal designation notice, which would be on file with the relevant federal agency.

Anthropuc PBC, a privately held AI safety company founded in 2021, develops large language models and competes in a sector that has drawn increasing federal scrutiny. The company has received investment from major technology and venture capital sources, and its designation as a supply-chain risk is distinct from any criminal or civil enforcement action. No criminal charges have been filed against the company, according to available public records.

The supply-chain risk framework allows the federal government to restrict or condition agency use of products or services from companies deemed to pose a risk to the integrity of federal information systems or critical infrastructure. Prior high-profile applications of this authority targeted foreign-linked firms such as Huawei and ZTE, which were added to restricted lists through actions by the Federal Communications Commission and the Department of Commerce. Applying a comparable designation to a domestically incorporated U.S. Company represents a different application of that framework.

The legal posture created by the appeals court decision is layered. The designation itself is now judicially affirmed at the appellate level. The earlier injunction lifting the operational ban, if still active, would be a separate order, and its continued effect would depend on whether the government or the court takes further action in light of the new ruling. The precise scope of both orders, including which specific business activities are covered or excluded, is not fully detailed in the available source material. The full text of the appellate opinion would specify those parameters.

For federal contractors and technology vendors, the case signals that courts are willing to uphold the executive branch's authority to apply national security designations to domestic AI companies. Legal practitioners following federal procurement law have noted that supply-chain risk authority has expanded substantially since the 2018 National Defense Authorization Act, which codified restrictions on certain vendors in federal contracts.

Congress has not acted legislatively to define the precise boundaries of supply-chain risk designations for domestic AI firms. The Senate Commerce Committee and the House Science, Space, and Technology Committee both have jurisdiction over issues touching AI and federal technology procurement, but no hearing specifically addressing the Anthropic designation appeared in the congressional record as of the date of this report.

The White House has not issued a public statement specifically addressing the appellate ruling as of September 25, 2026, according to available sources. Anthropic's public response to the ruling, if any, was not available in the source material reviewed.

For context on broader federal AI policy activity, the White House has separately convened meetings with AI executives on related regulatory and competitiveness questions, as previously reported by The Congressional Times in Trump and Johnson to Meet AI Executives at White House Tuesday.

What remains unknown is whether the government will seek to vacate the earlier injunction in light of the appellate ruling, and whether Anthropic will seek review by the full appeals court or petition the Supreme Court. The full appellate opinion, the original designation notice from the relevant federal agency, and any forthcoming agency action would be the public documents that would answer those questions.
