GM Backs US Rare Earth Magnet Firm After Selling Tech to China
GM is investing in MP Materials to rebuild domestic magnet production 30 years after selling its pioneering Magnequench business to Chinese investors.
General Motors is throwing its weight behind MP Materials, a new American rare earth magnet company, in a strategic bid to rebuild a critical EV supply chain that the automaker itself helped dismantle three decades ago. The move comes after GM sold its groundbreaking magnet subsidiary Magnequench to Chinese investors — a decision now widely regarded as one of the costliest industrial miscalculations in American automotive history.
MP Materials is building what its backers describe as the only full-scale permanent magnet manufacturing facility in North America. The plant is designed to produce the high-performance magnets that sit at the heart of modern electric vehicle motors, components that determine how efficiently those motors convert electricity into motion. Without reliable domestic sources, automakers have remained deeply exposed to foreign supply disruptions.

The rare earth magnet supply chain is extraordinarily complex, requiring raw material extraction, refining, alloying, and precision manufacturing — each step historically dominated by Chinese producers. GM's partnership with MP Materials signals a broader industry recognition that globalization-era outsourcing decisions created national security and commercial vulnerabilities that now demand costly correction.
The timing is pointed. As American automakers race to compete with lower-cost Chinese EVs both at home and abroad, controlling the supply of key drivetrain components has become a competitive imperative, not merely a policy talking point. GM's investment in MP Materials represents a bet that vertical integration and domestic sourcing can offset the pricing advantages Chinese manufacturers currently enjoy.
The arc from Magnequench's sale in the mid-1990s to today's MP Materials partnership illustrates how strategic decisions made in an era of uncritical globalization continue to shape — and constrain — American industrial policy a generation later. Continue reading at The Autopian.
