The rapid expansion of artificial intelligence infrastructure is reshaping global technology supply chains, moving the focus beyond advanced processors and high-bandwidth memory toward electricity, transformers, cooling equipment, optical networks and the specialised minerals and materials required to build them.
The first major constraint in the AI boom was concentrated in advanced GPUs and high-bandwidth memory. As data-centre capacity expands, however, the pressure is spreading across the physical infrastructure supporting increasingly powerful computing clusters. Electricity availability, grid equipment, cooling systems and high-speed connectivity are becoming critical factors, while demand for technology-specific raw materials is gaining strategic importance.
Copper illustrates the scale of the infrastructure shift. An AI training data centre can require around 47 tonnes of copper per megawatt, more than twice the approximately 21 tonnes associated with a cryptocurrency facility. Global copper consumption linked to data centres is projected to rise from about 1.1 million tonnes in 2025 to 2.5 million tonnes by 2040.
That growth is significant, but AI should not be viewed as the sole driver of the copper market. Electricity-grid expansion, electric vehicles, renewable-energy infrastructure and broader electrification remain major sources of long-term copper demand. AI is instead adding another rapidly expanding layer of consumption to an already competitive market for the red metal.
Gallium and Germanium Become Strategic Technology Bottlenecks
The more concentrated supply risks are emerging in much smaller markets, particularly gallium and germanium. Their volumes are tiny compared with copper, yet both materials play important roles in high-frequency electronics, semiconductor applications and optical communications.
The growth of AI computing is also increasing the need to move enormous quantities of data between processors and across data-centre networks. As bandwidth requirements rise, the industry is accelerating the adoption of silicon photonics and indium-phosphide laser technologies. That transition is creating additional strategic demand for germanium, indium and gallium.
In some applications, optical connections could reduce the amount of copper required within server facilities. Yet that does not eliminate material pressure. Instead, it changes the composition of the materials needed by the technology sector, shifting part of the demand toward specialised semiconductor and photonics inputs.
China remains central to this supply chain. The country is the leading refiner for 19 of the 20 strategic minerals monitored closely by the International Energy Agency, with an average market share of roughly 70%. China’s export licensing measures have already affected markets for gallium, germanium, graphite, antimony, tungsten and rare-earth products. Developments in 2026 have further demonstrated the geopolitical significance of these relatively small mineral markets. In June, China continued withholding several heavy rare earths from Japan and recorded no yttrium exports to the United States for a second consecutive month.
The lesson for technology manufacturers is increasingly clear: a material does not need to have a large global market to become strategically important. A small quantity of a difficult-to-replace mineral can create a disproportionate supply-chain vulnerability.
AI Semiconductor Growth Is Creating Winners and Losers
The semiconductor market itself is becoming increasingly differentiated. Advanced logic processors and high-bandwidth memory are expanding rapidly as AI accelerators and associated computing infrastructure scale up. That growth supports demand for electronic-grade silicon, copper, tantalum, tungsten, ruthenium, hafnium and advanced packaging materials.
At the same time, growth in consumer electronics and conventional automotive semiconductors is comparatively slower. That creates a less favourable environment for some mature-node manufacturing capacity, highlighting the widening gap between the materials and technologies required for leading-edge AI infrastructure and those used in more established electronics markets. For miners and refiners, this distinction is important. Semiconductor demand cannot be assessed simply through overall chip production. The value and strategic importance of the materials vary considerably depending on which generation of chips, packaging technologies and applications are expanding.
Silicon Carbide Market Moves From Scarcity Toward Competition
Silicon carbide (SiC) and gallium nitride (GaN) remain strategically important power-electronics materials, but their supply outlook is becoming more complicated.
Large-scale Chinese investment in silicon carbide has raised the possibility of wafer and device oversupply, increasing price pressure and creating tougher conditions for producers outside China. Demand nevertheless continues to expand across electric vehicles, charging infrastructure, renewable-energy inverters and power-conversion systems for data centres. The industry is also facing a manufacturing transition from 150mm to 200mm wafers. Larger wafers can improve production economics, but the shift requires manufacturers to achieve sufficient yields and reduce costs.
Companies including STMicroelectronics, Infineon, Wolfspeed, onsemi and Rohm, alongside rapidly expanding Chinese competitors, are therefore competing on manufacturing scale, efficiency and yield rather than operating in a market defined simply by a shortage of material. For investors and raw-material producers, the changing SiC market is an important reminder that strong structural demand does not automatically translate into high prices. Rapid capacity expansion can fundamentally alter market conditions even while end-use consumption continues to rise.
Solar Supply Glut Masks Demand for Technology Metals
Solar manufacturing provides another example of diverging material markets. Chinese expansion has pushed polysilicon, wafers and conventional solar modules into a state of substantial oversupply. Production capacity has grown faster than installations, driving prices lower and putting significant pressure on manufacturers’ margins.
Other materials tell a different story. Silver remains an important input for photovoltaic technology, while thin-film solar technologies require specialised materials including tellurium, cadmium, indium and gallium.
Manufacturers are working continuously to reduce the amount of silver used per watt of solar capacity. That efficiency trend could lower material intensity over time, but rapid global growth in solar installations is helping offset some of the reduction. The result is a market in which technology improvements can reduce material use per unit while total deployment continues to increase overall consumption.
High-Tech Manufacturing Depends on a Wider Mineral Base
The technology-materials story extends well beyond the minerals most commonly associated with batteries and electrification.
Rhenium is essential to high-temperature turbine superalloys, while beryllium is used in aerospace systems, satellites and precision instruments. Niobium has applications in superconducting technologies and specialised alloys, while titanium remains important for aerospace structures.
High-purity alumina is another specialised material with applications in semiconductor equipment, LEDs and battery separators. At the same time, engineered materials such as synthetic diamond, silicon nitride and technical ceramics are finding increasing roles in thermal management and high-performance electronic systems.
These materials may represent relatively small markets, but their importance can be substantial because they are often tied to demanding technical specifications and have limited substitution options.
E-Waste Could Become a Major Source of Technology Minerals
As technology consumption grows, discarded electronics are emerging as one of the world’s most valuable secondary sources of technology-related minerals. Electronic waste contains recoverable quantities of copper, gold, silver, palladium, tin, cobalt, tantalum and rare earths. The challenge is not necessarily the amount of metal present in discarded devices, but the difficulty of collecting the material, identifying components and separating valuable elements economically.
This creates an opportunity for companies capable of combining automated dismantling, hydrometallurgical processing and traceable refining. Such operators could recover substantially more value from discarded electronics than conventional scrap-processing businesses.
The development of efficient recycling infrastructure could also become strategically important for countries seeking to reduce dependence on imported minerals and diversify supplies of critical raw materials.
Five Technology Markets Are Reshaping Mining Demand
The relationship between technology and mining is therefore becoming more complex. Tracking only commodity prices is no longer enough to understand where future mineral demand and supply-chain risks are emerging.
Five interconnected markets deserve particular attention: semiconductors and photonics; AI data-cententre infrastructure; permanent magnets and robotics; solar technology and power electronics; and electronic-waste recovery. Each market has its own combination of minerals, processing requirements, manufacturing bottlenecks and geopolitical risks. Some materials face genuine supply constraints, while others are moving toward oversupply despite strong demand growth.
For the mining and metals industry, the most significant developments increasingly occur at the intersection of these technology supply chains and the upstream sectors that provide their raw materials. The strategic importance of a mineral is no longer determined solely by its price or market size. In the AI era, the decisive factor may instead be whether a specialised material can be supplied reliably, processed to the required purity and scaled quickly enough to keep pace with the infrastructure behind the global technology boom.
