Geopolitical Risk & Critical Minerals: The Top Supply Chain Constraint for Data Center Expansion in 2026

Data Center Critical Mineral Risks: How Resource Nationalism Shifted from Theory to Commercial Threat

The risk to data center expansion has shifted from a theoretical supply chain vulnerability between 2021 and 2024 to an immediate commercial threat driven by escalating resource nationalism and the weaponization of mineral processing dominance in 2025. The voracious demand for critical minerals from the AI-driven data center boom is now on a direct collision course with geopolitical realities, creating tangible cost, timeline, and viability risks for an industry projected to require $6.7 trillion in investment by 2030.

• The pre-2025 period was characterized by an awareness of supply chain concentration, with data from the IEA and CSIS highlighting China’s control over processing for minerals like cobalt (73%) and heavy rare earths (nearly 100%). This was largely viewed as a strategic but manageable risk.
• In 2025, this risk materialized into a direct commercial threat. The focus is no longer just on China’s market share but on the active use of this dominance as leverage, with the potential for a single policy decision in Beijing to halt global production lines for essential data center hardware.
• Compounding the issue, a new wave of resource nationalism has emerged in Africa and Latin America since early 2025. These nations are aggressively renegotiating mining contracts and imposing export restrictions to maximize domestic value, introducing significant uncertainty and higher costs for downstream users, including data center developers.
• The direct impact on data centers is now clear: rare earth elements such as neodymium for cooling systems and cobalt for battery backup are at the center of this geopolitical competition, linking digital infrastructure viability directly to international resource politics.

Strategic Investment Analysis: The West’s Scramble to De-Risk Critical Mineral Supply Chains

In response to escalating supply chain risks, strategic investment has pivoted from broad-based policy initiatives seen between 2021 and 2024 to targeted, large-scale capital deployment in 2025 aimed at creating alternative, non-Chinese processing and recycling capacity. This reactive investment surge underscores the severity of the perceived threat to both the energy transition and the AI infrastructure buildout.

• The most significant shift is the scale and specificity of capital. While the 2021-2024 period saw foundational policy like Canada’s Critical Minerals Strategy, 2025 brought high-value actions, exemplified by the $1.4 billion partnership between Vulcan Elements and Re Element Technologies to establish a secure, U.S.-based rare earth supply chain.
• Government intervention has become more direct and substantial. The proposed plan to deploy nearly US$12 billion to create a U.S. strategic reserve of rare earth elements signals a move to buffer against supply shocks, a direct countermeasure to China’s market dominance.
• Investment is also flowing into creating a circular economy for critical minerals to reduce reliance on primary extraction. The USD 25 million investment in Cyclic Materials’ recycling facility in June 2025 marks the launch of North America’s first commercial-scale rare earth recycling center, a key step in building a resilient secondary supply source.

Partnership Dynamics: Forging Alliances to Counteract Geopolitical Threats to Mineral Supplies

The nature of partnerships has evolved from research-focused collaborations before 2025 to strategic, multi-billion dollar alliances between governments, corporations, and international blocs. These new coalitions are explicitly designed to build resilient, parallel supply chains for critical minerals in response to weaponized trade dependencies.

• The $1.4 billion deal between Vulcan Elements and Re Element Technologies in November 2025 exemplifies the new model of public-private partnerships. It moves beyond research to create a vertically integrated industrial capacity within the U.S., a direct reaction to geopolitical risk.
• Multilateral groups like the Quad (U.S., India, Japan, Australia) have shifted from dialogue to action. In late 2025, these alliances are being leveraged to coordinate investment and offtake agreements, creating a bloc of allied nations to reduce collective dependence on single-source suppliers.
• Public financing is now being used to de-risk private investment in strategic sectors. The Canadian government’s $165 million loan to a domestic rare earths project in October 2025 is a clear example of state-directed industrial policy aimed at fostering a non-Chinese supply chain.

Geographic Hotspots: How Mineral Nationalism in China, Africa, and Latin America Threatens Data Center Growth

The geographic landscape of risk has intensified, shifting from a singular focus on China’s established dominance before 2025 to a multi-polar environment where emerging resource nationalism in Africa and Latin America now poses additional and more unpredictable supply chain threats. In response, North America is becoming the primary geography for de-risking and investment.

• China remains the central geographic risk, controlling approximately 90% of global rare-earth refining capacity. This provides Beijing with a powerful chokepoint over materials essential for magnets in data center cooling systems and wind turbines.
• A key shift in 2025 is the rise of active resource nationalism in other regions. Nations in Africa and Latin America are moving beyond rhetoric to renegotiate mining contracts and demand local processing, creating new layers of cost and timeline uncertainty for mineral projects that supply the global market.
• This escalating risk abroad has turned North America into a strategic geography for building alternative supply chains. The U.S. and Canada are now focal points for major investments in domestic processing and recycling, evidenced by projects from Vulcan Elements in the U.S. and Cyclic Materials in Ontario, Canada.

Supply Chain Maturity: From Raw Material Extraction to At-Risk Commercial Scale Processing

While extraction technologies for critical minerals are mature, the crucial mid-stream processing and refining stage has become the primary point of failure. This segment of the supply chain has moved from a recognized dependency before 2025 to a commercially weaponized chokepoint today that threatens the entire digital infrastructure ecosystem.

• In the 2021-2024 period, the technological focus was on improving the efficiency of mature extraction methods and the end-use applications in EVs or renewables. The mid-stream processing gap was a known vulnerability but not yet a source of acute commercial disruption.
• Since 2025, the strategic focus has shifted decisively to the “technology” of processing, refining, and recycling critical minerals within Western nations. The immaturity of this capacity in North America is precisely why it is attracting billions in state-directed and private investment.
• China’s advantage is not merely in physical capacity but in the operational expertise and intellectual property of mineral processing. The flurry of investment in companies like Vulcan Elements and Cyclic Materials is a direct attempt to fast-track the development of this missing industrial capability and close the maturity gap.

SWOT Analysis: Critical Mineral Supply Chain Risks for Data Center Expansion

The strategic landscape for critical minerals has become substantially more volatile, with soaring demand from AI colliding with severe geopolitical concentration. This dynamic has spurred reactive diversification investments under the immediate threat of supply weaponization, fundamentally reshaping risk calculations for data center developers.

• If this happens: Geopolitical actors continue to use mineral supply as a political tool. Watch this: An increase in announcements of long-term offtake agreements from hyperscalers, bypassing intermediaries to lock in supply directly from miners and refiners in allied nations. The 2025 government-backed projects in Canada will be prime targets.
• If this happens: The cost and risk of sourcing from dominant or unstable regions continue to rise. Watch this: A price premium develops for “de-risked” materials sourced from North American or allied supply chains, creating a two-tiered market. This will validate the business case for investments like the Vulcan Elements partnership.
• These could be happening: Leading tech companies may begin acquiring stakes in, or forming exclusive joint ventures with, mining and processing companies. This would represent a fundamental strategic shift from being a consumer of materials to a direct participant in the supply chain, moving beyond the partnership models seen to date.
