Pentagon inks classified AI deals with Nvidia, Microsoft, AWS after dropping Anthropic

The Pentagon formalized classified artificial intelligence agreements on May 1 with Nvidia, Microsoft, Amazon Web Services, and Reflection AI, bringing the total number of companies operating on secret military networks to seven. These new pacts join earlier deals with SpaceX, OpenAI, and Google , the latter having signed its own classified AI arrangement just days prior. Every agreement now permits what the Defense Department calls “lawful operational use,” a carefully chosen phrase that officials say advances the goal of transforming the U.S. military into an “AI-first fighting force.” That wording is no accident. It directly replaces the safety restrictions that Anthropic, the developer of the Claude model, tried to embed in its own Pentagon contract. When Anthropic refused to drop those limits, the Defense Department removed the company from its supply chain. The seven firms that remain have accepted terms Anthropic would not.

The core difference lies in what “classified military AI” actually allows. Anthropic’s stance, before the Pentagon labeled it a supply chain risk in February, was straightforward: it would not let its models be used for mass domestic surveillance of American citizens or for fully autonomous weapons systems. These were not vague aspirations but contractual red lines written into its $200 million Pentagon agreement awarded in July 2025. During renegotiations in late 2025 and early 2026, the Pentagon refused to accept those restrictions. When Anthropic held its ground, the Defense Department moved to eject the company entirely and replace it with rivals willing to sign broader terms.

The resulting phrase , “lawful operational use” , is expansive enough to cover targeting assistance, intelligence synthesis, and operational planning on secret and top-secret networks, without the specific prohibitions Anthropic demanded. Defense officials briefed on the matter say the new agreements give the Pentagon wide leeway to potentially use powerful advanced AI for secret combat operations, including targeting. The Pentagon pushed its deal with AWS late into Thursday evening, signaling urgency in finalizing the full set of contracts. An AWS spokesperson, asked about the arrangement, referred to the Defense Department as “the Department of War” , its name before 1947 , and said AWS “looks forward to continuing to support” its modernization efforts.

The seven companies now operating on classified Pentagon networks represent virtually the entire infrastructure layer of the American AI industry. Nvidia supplies the chips. Microsoft and AWS provide cloud infrastructure. Google offers Gemini. OpenAI provides GPT. SpaceX contributes satellite communications and, following its acquisition of xAI, AI models trained on data from X. Smaller defense-focused AI firms are also building for sovereign military applications, but the Pentagon’s priority is clearly the largest providers. Reflection AI, the least-known name among the seven, specializes in AI for classified and intelligence community applications.

The breadth of the arrangement is intentional. Defense officials have said they want to ensure the U. S. military “avoids depending on any one single company or set of limitations” , a statement that directly references the Anthropic fallout. The Pentagon does not want a single AI company’s ethical red lines to constrain military operations. The solution is diversification across seven providers, all of whom have agreed to terms that exclude the restrictions Anthropic insisted upon. The “AI-first fighting force” the Pentagon envisions requires AI available for any lawful purpose the military defines, without prior constraints imposed by the companies that build it.

Anthropic’s story runs in the opposite direction. The company was designated a supply chain risk , a label previously reserved for Chinese firms like Huawei and ZTE. Its $200 million Pentagon contract was effectively voided. Senior defense officials publicly criticized the company, and the Trump administration has since expanded the dispute to include opposition to Anthropic’s Mythos model and restrictions on its deployment in government systems. Commercially, the damage has been negligible. Anthropic’s valuation has risen to approximately $900 billion, up from $380 billion in February. Its largest compute deal, with Google and Broadcom, dwarfs the Pentagon contract it lost. The company’s revenue run rate is roughly $30 billion. Being ejected from the Pentagon’s classified networks has not, at least in the short term, hurt its business.

What it has done is establish a clear precedent. Any AI company that sets specific limits on military use of its technology will be replaced by one that does not. The Pentagon’s message, delivered through seven simultaneous agreements with competitors, is that the Department of Defense will not negotiate the scope of military AI use with the companies that build it. “Lawful operational use” means the military decides what is lawful and what is operational. The companies provide the technology. The question of whether AI should assist with targeting, or whether fully autonomous systems should make lethal decisions, is not one the Pentagon intends to resolve through commercial contracts. It is one the Pentagon intends to resolve by selecting vendors who do not ask it.

The practical implications are significant. AI deployed on Impact Level 6 and Impact Level 7 classified networks will be used for intelligence analysis, operational planning, and synthesizing data from sources that are themselves classified. The Pentagon’s statement says these tools will “streamline data synthesis, elevate situational understanding, and augment warfighter decision-making in complex operational environments.” In plain terms: AI will help analysts process intelligence faster, help commanders understand battlefields in closer to real time, and help targeting teams identify and prioritize objectives. SpaceX’s expanding AI capabilities, acquired through its merger with xAI, add a dimension that did not exist when the Pentagon first began negotiating these deals: a satellite communications company that also builds AI models, operating on the same classified networks that process targeting data.

The speed of the Pentagon’s pivot is itself a statement. Five months ago, Anthropic held a $200 million contract and was the most prominent AI company working on classified military systems. Today, seven competitors have signed agreements that collectively render Anthropic’s military contribution replaceable. The Pentagon has answered a question the AI industry has debated since the first Google employee protested Project Maven in 2018: whether the companies that build the most powerful AI systems will have a say in how those systems are used by the military. The answer, delivered across seven contracts in a single week, is no.
