The escalating demand for rare earth elements critical to artificial intelligence (AI) and advanced technologies is prompting renewed attention to domestic supply chains in the United States, amid broader geopolitical tensions and supply vulnerabilities. A recently highlighted deposit in Mountain Pass, California, long regarded as a dormant mining site, is thought to contain vast reserves of neodymium, gallium, lithium, and other rare earth elements essential for powering AI infrastructure, semiconductors, electric vehicles, and data centres. According to an analysis by Brownstone Research, this discovery could be worth an estimated $100 trillion in future AI metal value, potentially transforming America’s position in the global race for technological independence.
These rare earth elements, sometimes termed “AI metals,” are indispensable due to their unique electromagnetic and thermal properties that enable high-performance computing, energy storage, and manufacturing efficiency. For instance, neodymium is critical for electric vehicle motors and data centre magnets, gallium is key in ultra-fast AI chips, and lithium fuels high-capacity batteries. As AI technologies proliferate, the pressure to secure reliable sources of these materials is intensifying, especially given China’s dominant control over over 80% of global rare earth production and 90% of processing capacity. This dominance has repeatedly exposed Western companies and governments to supply chain disruptions, motivating increased domestic production efforts and legislative support through initiatives like the U.S. CHIPS Act and Department of Energy funding.
Within this context, MP Materials, the operator of the only significant rare earth mine in the U.S., stands out as a pivotal player. The company, revived from bankruptcy by hedge fund manager James Litinsky, has recently cemented major partnerships that underscore the strategic importance of securing these materials domestically. Notably, MP Materials secured a $400 million investment from the U.S. Department of Defense and a $150 million low-interest loan, alongside a $500 million deal with Apple to produce recycled rare earth magnets for use in iPhones. The Pentagon’s deal includes a commitment to purchase all magnets produced at a new factory over the next decade and sets minimum price guarantees for critical elements like neodymium and praseodymium. These arrangements aim to shield MP Materials from volatile pricing influenced by China and secure a steady supply for defence and high-tech industries.
These commercial and government partnerships have bolstered MP Materials’ market valuation to nearly $9 billion and catalysed a 50% surge in its stock price following announcement, reflecting investor optimism on reshoring critical mineral supply chains. Yet, despite these advancements, analysts caution that MP Materials alone cannot satisfy the total U.S. demand for rare earths, signalling a broader need for investment in mining and processing infrastructure across the supply chain.
In parallel, trade tensions and export controls are shaping the rare earth and AI materials landscape. Recent negotiations have seen the U.S. ease export restrictions on Nvidia’s AI chips to China, following China’s agreement to relax control on seven rare earth elements vital for defence and clean energy. This move, confirmed by the U.S. Commerce Secretary, highlights the complex dynamics where technological leadership and supply chain security are closely intertwined. Nvidia’s CEO warned that extended restrictions might undermine U.S. dominance in AI development, while the administration balances strategic containment with market considerations. This bilateral adjustment contrasts with the more nationalist tone of American mining executives like Litinsky, who now publicly criticise Chinese market practices despite previous partnerships.
Broader market projections suggest demand for these AI-critical metals could surge exponentially through 2030, with expected annual investment in global AI infrastructure exceeding $2 trillion. This demand growth is propelled by the convergence of AI technologies, electric vehicles, renewable energy systems, and next-generation computing platforms. Governments in the U.S. and Europe are prioritising mineral independence and supply chain resilience as core elements of industrial strategy, investing heavily in capacity expansion, processing technologies, and sustainability initiatives aimed at reducing environmental impacts. Recycling and circular economy practices are also emerging as key avenues to supplement primary mining and address ethical concerns surrounding extraction.
However, investment in the rare earth sector carries notable risks. Commodity price volatility, geopolitical tensions, regulatory uncertainties, technological substitution, and operational hazards pose challenges to both producers and investors. Analysts highlight the cyclical nature of commodity markets, with boom-bust cycles that can lead to financial instability if not carefully managed. Environmental, social, and governance (ESG) considerations have grown in prominence, influencing financing and regulatory landscapes, and necessitating advances in sustainable mining methods.
In summary, the rediscovery and development of AI-critical rare earth deposits such as Mountain Pass, coupled with strategic government and corporate initiatives exemplified by MP Materials, represent significant steps towards reducing the U.S.’s reliance on China for high-tech minerals. While these efforts offer a pathway to technological self-sufficiency and greater geopolitical leverage, the complexity of global supply chains and growing demand will require sustained investment, innovation, and regulatory coordination to secure a resilient and sustainable AI metal ecosystem.
