Pentagon Nears Complete Migration of Classified AI Workloads Off Anthropic by October

BLUFDOD will likely finish removing all classified AI workloads from Anthropic by late September, rendering the pending D.C. Circuit ruling operationally moot regardless of outcome.

Under Secretary of Defense for Research and Engineering Emil Michael told reporters at the NDIA Emerging Technologies for Defense Conference that roughly 90% of the Pentagon's classified AI workloads have already shifted off Anthropic models, with full migration targeted by the end of September 1. He said all Maven Smart System and Palantir-related work moved months ago 1. Michael attributed the shift to a breakdown in contract talks after Anthropic sought restrictions on surveillance and autonomous-weapons uses that DOD deemed incompatible with "all lawful purposes" requirements, leading the department to designate Anthropic a national security supply chain risk 1. Michael said the dispute is now being litigated in two courts, with a D.C. Circuit ruling expected within one to two months, and separately rejected an Anthropic researcher's public AI-risk warning 12.

Analysis
Full migration of classified AI workloads off Anthropic by September 30 is likely, with the pending D.C. Circuit ruling largely irrelevant to operational posture: Maven Smart System and Palantir integrations completed months ago, and the remaining share now runs on an internal schedule rather than awaiting judicial action. A ruling expected within one to two months could lift the supply-chain-risk designation, but DOD's build-out of OpenAI, xAI, and Google alternatives forecloses near-term reinstatement to classified networks regardless of outcome. Confidence is high, given consistent on-record statements from the same senior DOD official across venues and no sign the residual workload faces technical obstacles, though sourcing rests on one primary briefing thinly corroborated by a second outlet. Officials may be publicizing operational independence to bolster DOD's legal position ahead of the ruling rather than describing a purely technical timeline. A completed migration closes off near-term reinstatement even if the court rules against DOD, leaving only a narrow window for negotiated restoration should the migration stall.
