Rare Earth Minerals & AI Supply Chain Geopolitics
Premium Analysis
The AI revolution runs on rare earth elements. Every GPU cooling fan, every data center motor, every robotic actuator, and every EUV lithography machine depends on neodymium-iron-boron magnets. China controls 60% of global extraction and over 90% of processing capacity. This concentration has now become the most consequential chokepoint in the global technology supply chain.
The Rare Earth Bottleneck
There’s a fascinating tension at the heart of AI infrastructure that most technical discussions completely miss: the more we digitize, the more we depend on what’s underground. Every optimization algorithm, every autonomous system, every data center promising to replace human labor rests on a foundation of physical extraction that looks nothing like the sleek interfaces we interact with.
In October 2025, Beijing deployed its most aggressive export control regime yet: extraterritorial jurisdiction over any product containing 0.1% or more Chinese-sourced rare earths by value. This measure, modeled after U.S. semiconductor export controls, effectively weaponizes the physical foundation of AI infrastructure.
Brazil has emerged as the pivotal countermove. Brazil has the world’s second-largest proven reserves of rare earths behind China, but has struggled to develop them due to a lack of capital and expertise. With only 30% of its territory geologically mapped, Brazil represents the most significant opportunity to break China’s processing monopoly.
The January 2026 U.S.-Brazil negotiations signal a potential restructuring of global critical minerals supply chains.
