Humanoid Robots Could Ignite a Rare-Earth Magnet Boom-but China Owns the Starting Grid

Highlights

• Morgan Stanley projects over one billion humanoids deployed by 2050, with China operating roughly 302 million versus 78 million in the U.S.
• China's dual dominance in humanoid manufacturing and rare-earth magnet production creates a self-reinforcing cost advantage that is difficult for U.S. firms to break.
• Tesla is the only U.S. humanoid maker with clearly documented Chinese magnet dependency; other firms like Figure AI and Agility Robotics carry unquantified embedded exposure.
• MP Materials' Northlake plant targets 10,000 tonnes of NdFeB annually by 2028, but REEx gives only 35% odds that U.S. humanoid makers achieve majority-domestic magnet sourcing by 2030.
