Grok Gains Access to US Military Classified Systems as Pentagon Leadership Shifts; Anthropic Excluded for Refusing Surveillance

The global military AI landscape is undergoing a major shift. On February 24, 2026, according to cnBeta , Axios reported that Elon Musk's AI company xAI has officially signed an agreement with the U.S. Department of Defense, enabling its large model Grok to be deployed within the military's most sensitive classified systems.
Key Shift: Grok Fills the Void Left by Anthropic
Previously, Anthropic 's Claude served as the sole AI backbone for the U.S. military's classified systems, handling weapons development and battlefield intelligence. However, serious disagreements have recently surfaced between the two parties:
Disagreement on Principles: Anthropic strictly forbade Claude from being used for mass surveillance or the development of fully autonomous weapon systems.
Musk's "Straightforward" Approach: In contrast, xAI accepted the Pentagon's "usable for all legal purposes" standard, opening the door for military use in sensitive areas.
Breakthrough: Pentagon Threatens Sanctions Against Anthropic
The Pentagon has adopted a firm stance against Anthropic 's refusal to cooperate:
"Last Chance": Defense Secretary Pete Hegseth plans to meet with Anthropic CEO Dario Amodei this week. If the company does not lift its usage restrictions, the Pentagon may label it as a **"supply chain risk"** and impose penalties.
Replacement Cost: While the Pentagon has begun searching for alternatives, officials acknowledge that removing and replacing the deeply integrated Claude system from critical missions is an extremely complex process.
Corporate Competition: Gemini and ChatGPT Speed Up Their Bid for Entry
The opportunity to access the classified system is driving a competitive rush among Silicon Valley giants:
Google Gemini: It is reportedly "close" to finalizing an agreement for deployment within the classified system.
OpenAI: While already in use by the U.S. military in non-classified settings, its advancement into the classified system has been slow.
Unified Standards: Officials from the Biden administration have stressed that any model entering the classified system must comply with the "full-use" standard, placing AI vendors squarely in a dilemma between technical ethics and government contracts.
Industry Insight:
Musk's xAI has seized the opportunity with a more flexible (or more aggressive) compliance stance, significantly enhancing its standing in the military AI space while signaling that future AGI competition will inevitably be deeply intertwined with national security and weaponization.
