Pentagon Signs AI Deals with OpenAI, Google, Microsoft, and SpaceX for Classified Networks

The Pentagon has signed agreements with OpenAI, Google, Microsoft, and SpaceX to deploy artificial intelligence tools on classified military networks, according to reporting from Tech Startups in May 2026.

The deals mark a significant expansion of AI use in US defense operations. Details about the specific capabilities being deployed remain limited due to the classified nature of the networks involved.

The agreements come as AI defense startups are also attracting major investment. Allen Control Systems, which specializes in autonomous counter-drone systems, is in discussions for a new funding round at a $2 billion valuation.

The military AI push is happening alongside growing warnings about cybersecurity risks. Cybersecurity agencies from the United States, United Kingdom, Canada, Australia, and New Zealand issued a joint warning about new risks from AI agents deployed in enterprise and critical infrastructure environments.

A separate incident highlighted those risks in practice. A ransomware group called ShinyHunters claimed responsibility for breaching Instructure, the parent company of the Canvas learning management system, affecting millions of student records during final-exam week.

Reports also indicate that threat actors used Claude AI to guide intrusions into operational technology assets of a Mexican water utility, demonstrating that AI tools are being used by attackers as well as defenders.

US cybersecurity officials are considering shorter deadlines for fixing critical government IT vulnerabilities, anticipating that AI tools will allow attackers to exploit weaknesses faster than before.

The US Treasury Secretary stated that banks are strengthening defenses against AI-enabled cyber threats, reflecting the financial sector's awareness of the growing risk.
