A new court hearing in Washington, starting this Tuesday, will reactivate the dispute between the Pentagon and the artificial intelligence company Anthropic, which for now has been limited to participate in defense projects, since the Administration of the president of the United States, Donald Trump, classified it as a “risk” to national security.
An Appeals Court in the US capital will hear arguments on the Pentagon’s decision to classify Anthropic as a possible “risk to the supply chain”, a measure that can block federal contracts and limit its presence in defense-related projects.
These are the keys to understanding a case that has opened a debate that goes beyond a single technology company and fuels the discussion about the role that AI companies should play in military programs.
1.- The beginning of the battle
The dispute began last February, when Secretary of War Pete Hegseth announced that the Pentagon would designate Anthropic as a “supply chain risk,” a figure used by the US government to restrict suppliers considered problematic for national security.
According to US media and the company itself, the conflict arose after Anthropic tried to maintain restrictions to prevent its AI model from being used in mass surveillance of US citizens or in fully autonomous weapons.
The company sued the Pentagon in March and Hegseth defended the government’s position, saying that “American warfighters will never be held hostage to the whims of Big Tech.”

2.- What does Anthropic argue?
Anthropic, founded in 2021 by former OpenAI researchers including Dario and Daniela Amodei, focused on security and control, maintains that the Pentagon’s decision was arbitrary and that the administrative process did not respect basic legal guarantees contemplated in federal legislation.
The technology company said, at the beginning of the dispute, that it had “no choice” but to challenge the grievance in court and federally sued the Pentagon on the grounds that the designation jeopardizes the rights of freedom of expression and due process.
Finally, the company maintains that the case marks a historical precedent regarding the limits of government power to restrict the scope of artificial intelligence providers.
3.- The judicial path
The litigation has progressed through different levels of the judicial system with files open in both Washington and California.
In its first phase, the case was filed in Federal Court in San Francisco, where Anthropic requested an injunction to stop the immediate application of the Pentagon’s designation as a “supply chain risk.”
In that instance, the judge allowed a partial temporary blocking of the measure while the underlying arguments were analyzed, considering that there were indications of possible administrative retaliation and violations of freedom of expression.
Subsequently, the case was transferred to federal courts in the capital, where the core of the litigation remains and in this jurisdiction, the Pentagon was authorized to provisionally maintain the designation, stating that the Executive has a wide margin of “discretion” when invoking reasons of national security.
4.- A new audience in Washington
This Tuesday’s hearing corresponds to the oral arguments phase of the appeal process that pits Anthropic against the War Department.
This is not a final trial, but rather an instance in which lawyers from both sides will present their arguments before federal judges.
The judges will have to evaluate whether the Pentagon acted within its powers by classifying the company as a possible strategic risk to federal and military technological infrastructure.
5.- What is at stake
The conflict between Anthropic and the Pentagon has been described by analysts and local media as a case that could mark the extent of government oversight over artificial intelligence companies that work with the public sector.
According to newspaper reports Washington Postexecutives from the technology and defense sectors have warned that the case could have a direct impact on federal contracts for companies that develop artificial intelligence.
Among them, executives linked to companies that already work with the Pentagon have indicated, on condition of anonymity, that a designation as a “risk to the supply chain” could generate uncertainty in future tenders and in the continuity of agreements already signed.
The process is closely followed by the sector due to the possible effect on future tenders and public-private alliances and as well as possible restrictions to develop tools in the military field.
