Defense designations reshape AI markets

When the U.S. military or other large federal purchasers formally labels an AI model or vendor a 'supply‑chain risk' (or bans its use), that designation can force prime contractors and cloud providers to divest, cut ties, or switch suppliers, immediately altering valuations, partnerships, and which models scale into critical infrastructure. — This creates a lever by which national‑security policy can rapidly reallocate commercial AI power and influence geopolitical competition and corporate strategy.
