OpenAI Hardware Chief Kalinowski Resigns Over Military Deal Dispute
On March 8, 2026, Caitlin Kalinowski, head of hardware development at OpenAI, announced her resignation. Her departure was prompted by a controversial new partnership between OpenAI and the U.S. Department of Defense. Kalinowski, a key figure who previously led augmented reality projects at Meta, joined OpenAI in November 2024. Her exit during a pivotal phase for the company's hardware strategy has attracted significant industry attention.

In a social media statement, Kalinowski described her decision as "a matter of principle." She expressed concern that the agreement enables surveillance without judicial oversight and grants AI lethal autonomous authority, issues she felt were not properly debated. She criticized OpenAI for announcing the partnership before establishing clear safeguards, calling it a major governance failure.
Partnership Backlash and Market Reaction
The controversy started a week prior when the Pentagon engaged OpenAI after talks with Anthropic stalled. Anthropic had been deemed a "supply chain risk" for refusing clauses related to mass surveillance and autonomous weapons. OpenAI agreed to the partnership, pledging to implement technical guardrails within a secure government cloud. This abrupt move sparked public and internal employee backlash.
Key Data and Impact:
User Loss: Following the announcement, daily uninstalls of the ChatGPT app in the U.S. surged by 295%.
Market Shift: Competitor Anthropic's Claude app quickly rose to the top of the U.S. App Store, displacing ChatGPT.
Internal Protest: Nearly a thousand tech workers from OpenAI, Google, and other firms signed an open letter condemning the militarization of AI.
An OpenAI spokesperson stated the partnership represents a responsible path for AI in national security. However, CEO Sam Altman later acknowledged that announcing the deal at this time was "opportunistic and rushed."
