Despite Trump administration backing, US rare earth element miners are selling their output to Japan and South Korea rather than building a domestic supply chain. The shift reflects weak domestic demand from US manufacturers, undermining efforts to reduce American reliance on Asian sources for critical materials used in semiconductors, defense systems, and AI hardware.
Why it matters: Supply chain resilience for rare earth elements is foundational to US semiconductor and AI competitiveness, making this divergence between policy intent and market reality a significant indicator of structural challenges in reshoring critical manufacturing.
