In the week since Fluet’s initial analysis of the President’s directive to phase out Anthropic technologies from Executive Branch agencies, significant details have emerged regarding the dispute between the Administration and Anthropic.

  • The Pentagon has invoked both 10 U.S.C. § 3252 and 41 U.S.C. § 4713 to implement the policy put out by the White House. Designation of Anthropic as a “supply-chain risk to the national security” under both § 3252 & 4713 effectively mandates elimination of Anthropic products from the federal supply chain, potentially impacting contractors and subcontractors at every tier.
  • Anthropic has filed two federal lawsuits in response:
  • Meanwhile, according to reports, the military continues to use Claude incorporated into systems used in active combat operations in Iran.

For federal contractors, this situation has moved from a “watch and wait” posture to one requiring active risk management. The pace of the Administration’s actions has outrun the legal and regulatory processes. Contractors caught in the middle need to understand the new legal landscape emerging from the Administration’s broader acquisition reform and industrial policy agenda.

Here are four critical implications every federal contractor needs to understand:

1) The Anthropic Suits Have Broad Implications

The Pentagon chose to employ all the options available against Anthropic and, as expected, Anthropic has chosen to challenge these actions in court. The actions by the Pentagon and the legal theories raised by Anthropic have implications far beyond this single dispute. If the government can designate a domestic company as a supply chain risk, using authorities historically reserved for foreign adversaries, as retaliation for refusing to accept the government’s preferred contract terms, the precedent would fundamentally alter the bargaining position of every government contractor. As Anthropic stated in its complaint, this would mean the government can “wield its enormous power to punish a company for its protected speech.” This action impacts not just Anthropic. All Federal contractors may find themselves in the crosshairs. The outcomes of the Anthropic challenges will shape the boundaries of government authority in procurement for years to come

2) The Supply Chain Risk Designation Functions as De Facto Debarment and Will Provide the Basis for Future Suspension and Debarment Actions

One of the most troubling aspects of the Administration’s approach is the way the supply chain risk designation operates in practice. As we noted in our initial analysis, formal suspension and debarment under FAR Subpart 9.4 requires specific procedural steps—notification, an opportunity to respond, and a decision by a properly designated Debarring Official. These procedures exist to prevent arbitrary government action and protect the due process rights of contractors.

Designation of Anthropic as a supply chain risk is, in effect, a debarment—achieved through executive fiat rather than administrative process. As Professor Jessica Tillipman of GW Law School argues in a comprehensive analysis published in Lawfare today, the federal procurement framework is now carrying policy questions it was never designed to answer, and the Administration’s approach is “dismantling the governance infrastructure” that might have answered them. When the government can effectively exclude a company from the federal marketplace through social media posts and supply chain designations, bypassing the procedural protections established through decades of jurisprudence and regulations promulgated by federal agencies addressing contractor responsibility, every contractor is at risk.

Furthermore, designation of Anthropic products and services as “covered articles” under § 4713 renders every federal contractor and subcontractor that uses Claude or incorporates Anthropic products in its IT infrastructure a supply chain risk by extension. By this designation, these contractors face significant legal uncertainty now and, once the phase-out period expires, will be exposed to the full range of remedies available to the government, including suspension or debarment.

3) The Administration Is Governing by Speed, Not by Process

The Anthropic situation should be understood in the context of the Administration’s broader strategy of prioritizing speed over established regulatory process. The pattern is now unmistakable: the Revolutionary FAR Overhaul (RFO) is using class deviations to implement sweeping changes to the Federal Acquisition Regulation prior to formal rulemaking; the “Prioritizing the Warfighter” Executive Order sought to impose unprecedented government control over contractor corporate governance with 15-day remediation timelines; and the Hegseth AI Strategy Memo gave vendors 180 days to accept “any lawful use” language or face exclusion.  The emphasis across the board is speed and getting in line with Administration policy over deliberation and process.

4) Contractor Compliance Obligations Are Materializing

What was a theoretical risk in our initial analysis has materialized into a concrete compliance obligation. The formal supply chain risk designation letter has been issued. Contractors are now likely expected to certify non-use of Anthropic’s products in their work with all federal agencies. The six-month phase-out window is running.

What to Watch Next

  • Court Cases. We will be monitoring the Anthropic suits closely, as their outcome will have significant bearing on all government contractors.
  • Congressional Response. Congressional reaction over time will be telling.  Legislative action such as oversight hearings, appropriations riders, or additions to the National Defense Authorization Act for Fiscal Year 2027 could alter the landscape for contractors and either accelerate the Administration’s actions or be a countervailing force.
  • Scope of Contractor Certifications. The practical scope of the non-use certification requirements remains uncertain. Contractors need clarity on whether certifications cover only direct use of Anthropic products and services or extend to third-party applications that incorporate Anthropic products. Fluet will be monitoring agency actions and guidance on implementation closely.
