Advanced Materials Companies in the United States
Composites, energetics, rare earth magnets, critical minerals and in-orbit manufacturing. Dependence on China for key inputs has turned materials into a national security issue, and a new group of US companies is working to rebuild domestic supply. Together they have disclosed $383M in funding, led by Phoenix Tailings (>$150M). The newest round on record is INTALUS's Seed extension (Jul 2026).
