- Defense CTO Emil Michael said Anthropic’s Claude has a built‑in “constitution” that imposes policy preferences, arguing the military must be free to use AI for all lawful purposes.
- An internal memo set a roughly 180‑day phase‑out of Claude from defense systems and requires contractors to certify non‑use, with limited exemptions for mission‑critical cases lacking alternatives.
- Anthropic sued in federal court, calling the designation unlawful and warning of irreparable harm to hundreds of millions in contracts as it seeks to block enforcement.
- Palantir CEO Alex Karp confirmed Claude remains in use on U.S. military operations during the transition, with Pentagon officials saying the technology cannot be removed overnight.
- Microsoft filed an amicus brief supporting temporary relief for Anthropic and warning of disruptions, as rivals move to replace Claude on classified networks and OpenAI acknowledged revising its own deal after backlash.
