Critical Minerals: The Real Bottleneck for AI and Data Center Growth in 2025

AI’s Material Appetite: How the Mineral Demand Shock is Reshaping Data Center Projects in 2025

The rapid expansion of Artificial Intelligence is no longer constrained by algorithms or semiconductor capacity, but by a physical-world bottleneck: the supply of critical minerals. The AI-driven demand shock for materials to build and power data centers has collided with an inelastic and geopolitically fraught supply chain, moving the constraint from a future risk to a present-day reality that dictates the pace and cost of infrastructure deployment.

• Between 2021 and 2024, the industry operated on forecasts, with the IEA projecting data center electricity use to double by 2026 and analysts noting the chronic underinvestment in the mining sector. This period was defined by an awareness of a looming problem, exemplified by China’s 2023 export controls on niche metals like gallium and germanium, which served as an early warning signal.
• From 2025 to today, this theoretical risk has materialized into a direct economic constraint. Hyperscaler CAPEX is projected to jump 44% year-over-year to $371 billion in 2025, and the IEA’s forecast for electricity demand has been revised upward to 945 TWh by 2030. This demand surge has driven copper prices up 28% in 2025 to around $5.10 per pound and triggered more aggressive geopolitical actions, including China’s October 2025 export controls on rare earths.

• The formation of the $1.8 billion Orion Critical Mineral Consortium in October 2025 marks a pivotal moment, representing a large-scale, coordinated effort to develop secure and responsible mineral sources specifically for the U.S. and its allies. This moves beyond policy papers to direct capital deployment.
• Element USA’s $850 million investment in a Louisiana rare earth and critical minerals refining facility, announced in December 2025, is a direct countermeasure to China’s processing dominance. This investment aims to establish a domestic refining capability, a critical missing link in the Western supply chain.
• This contrasts sharply with the 2021-2024 period, which was characterized by broad underinvestment. The top 30 global miners only increased CAPEX by a modest 6.2% in 2023, an insufficient response to the demand signals from AI and decarbonization technologies.

Corporate and Geopolitical Alliances Form to Counter AI’s Mineral Supply Chain Risk

The recognition of mineral constraints has catalyzed the formation of both high-level geopolitical alliances and direct corporate partnerships. These collaborations are designed to de-risk supply chains by diversifying sources, securing offtake, and investing in new extraction technologies, representing a strategic shift from passive procurement to active supply chain management.

• In December 2025, the U.S. initiated an eight-nation alliance focused on coordinating the entire AI supply chain, including critical minerals, energy, and logistics. This government-led effort complements the EU’s 15 existing partnerships with resource-rich nations like Chile and Canada, creating a bloc aimed at countering Chinese dominance.
• Hyperscalers are now engaging in direct partnerships with producers, exemplified by the recent agreement between Amazon Web Services (AWS) and Rio Tinto. This deal secures a supply of low-carbon copper from Rio Tinto’s Nuton bioleaching technology for use in AWS’s U.S. data centers, linking infrastructure growth directly to specific, sustainable mining outputs.
• These targeted actions in 2025 are an evolution from the foundational work done between 2021-2024, such as the establishment of the broader Minerals Security Partnership (MSP). The recent partnerships are more commercially specific, linking end-users like AWS directly to mining innovation.

Geopolitical Chokepoints: How Mineral Concentration in China Constrains Global AI Expansion

The geographic concentration of mineral processing has shifted from a latent supply chain risk into an active geopolitical lever, primarily wielded by China. This dominance over refining gives China significant control over the physical inputs required for AI hardware, creating a critical vulnerability for Western nations and forcing a scramble to develop alternative, geographically diverse supply chains.

• Between 2021 and 2024, China’s market position was a known fact, with the country controlling over 90% of rare earth processing and a majority of many other critical minerals. Its 2023 export controls on gallium and germanium were a clear demonstration of its willingness to use this dominance as a strategic tool.
• This threat was fully realized in October 2025, when China imposed stringent export controls on rare earths and magnets, directly threatening the supply of essential components for AI chips, server hard drives, and cooling systems. This action escalated the risk from niche applications to the core of data center hardware.
• In response, investment is now flowing toward geopolitically stable regions to build alternative capacity. Key examples include Element USA’s $850 million refining facility in Louisiana and strategic initiatives in allied nations like Canada and Australia, which are leveraging their resource wealth to attract investment.

From Discovery to Deployment: Can Technology Overcome the Mineral Constraint on AI Growth?

While the long lead times for new mines remain a structural barrier, technology is emerging as a critical tool to mitigate mineral constraints. The industry is now deploying AI to accelerate mineral discovery and developing advanced materials to improve efficiency, representing a crucial, albeit long-term, response to the immediate supply shock.

• The period from 2021 to 2024 saw the initial application of AI in mineral exploration, with companies like Ko Bold Metals using algorithms to analyze geological data. This was largely in the R&D and pilot phase, with programs like DARPA’s Critical MAAS aiming to build foundational AI tools.
• In late 2024 and 2025, this approach has gained validation. The first AI-driven greenfield mineral discovery by Earth AI demonstrated the technology’s potential to shorten discovery timelines. Simultaneously, new material technologies are targeting efficiency, such as Green Critical Minerals’ VHD graphite for improved data center cooling and Rio Tinto’s Nuton bioleaching, which enables economic extraction from low-grade copper sources.
