When AI Meets Commodities: A Metal Restructuring of Global Infrastructure

When Artificial Intelligence Begins to Consume Metals

For a long time, commodities were regarded as synonymous with the old economy—highly cyclical and dull in long-term growth. But the global picture in 2026 is changing this assessment.

The AI race is no longer just a virtual game of code, chips, and data centers. It is becoming a real material consumption war. The latest outlook from BHP's chief economist team reveals a frequently overlooked fact: AI cannot be built without metals. Copper is a core material for chips, data centers, and power infrastructure; steel is the foundation supporting all physical structures; and uranium has returned to strategic view due to energy security considerations.

This is not a simple recovery in demand, but a fundamental restructuring of the human economic system.

An Unprecedented Flood of Capital

The measure of this change is the absolute scale of capital expenditure. BHP analysis shows that the largest U.S. hyperscale cloud providers alone are expected to invest $700 billion to $800 billion in AI-related construction in 2026, equivalent to 2.4% of U.S. GDP.

What does this number mean? In terms of peak annual spending, it exceeds the combined broadband and telecommunications investment during the internet bubble era, and also surpasses the historical peak spending on the Apollo program and the interstate highway system. More importantly, it is even larger than the sum of all three.

And this flood of investment is spreading globally. South Korea has announced an AI investment plan of about $1 trillion over the next decade; China is also considering spending about $295 billion over the next five years to expand data center capacity. When major global economies unanimously treat AI as the core of national strategy, the boundaries of its resource consumption will far exceed current market expectations.

BHP has estimated a sobering conversion relationship: for every additional $200 billion in average annual data center investment, a new copper mine with an annual output of 150,000 tonnes is needed to meet its hardware and electricity demand. Existing copper reserves and production lead times are far from sufficient to match this pace.

Electricity: The Scarce Resource of the New Era

The expansion of AI infrastructure is essentially an electricity race. According to the International Energy Agency, electricity demand from AI data centers surged 50% in 2025 and is expected to double by 2030, equivalent to adding a power market the size of Germany (about 500 terawatt-hours). In an optimistic scenario, this increase could even exceed Japan's annual electricity consumption.

The restructuring of electricity supply has therefore become a core driver of commodity demand. Data centers require copper-based electrical systems, transformers, and grid infrastructure; renewable energy—solar and wind—is also highly dependent on copper and steel; and to ensure energy security, nuclear power technologies such as small modular reactors (SMRs) have regained attention, directly boosting demand for uranium.Global power grids are under unprecedented connection pressure. The IEA points out that more than 2,500 gigawatts of renewable energy, energy storage, and large-scale load projects—mainly data centers—are currently waiting to connect to the grid. This reflects both the surge in electricity demand and the severe lag in grid infrastructure across countries.

China has already identified power infrastructure as a key pillar in its 15th Five-Year Plan, with power investment expected to grow from 2.8 trillion yuan to 5 trillion yuan over five years—an increase of as much as 80%. In the United States, forecasting agencies expect cumulative grid and utility capital expenditures to increase by $550 billion to $1.4 trillion over the next five years.

India's "Infrastructure Moment"

If AI is the short-term accelerator, then India is the structural engine for the coming decades.

The foundation of global commodity demand has always been population growth, urbanization, and rising living standards. While China has entered a stage of high-quality development, India is in the upward phase of a Kondratiev long wave—its infrastructure and capital stock remain far below the levels of developed economies.

The data is highly compelling. Per capita steel stock in developed countries ranges from 11 to 13 tons; China has already reached about 10 tons, while India has only about 2 tons. The gap in copper stock is even larger: developed economies have nearly 200 kilograms of cumulative copper per capita, but India has only 15 kilograms. This gap means that for India to reach the infrastructure level of developed economies, it would need hundreds of millions of tons of steel and tens of millions of tons of copper—a physical construction cycle spanning decades.

In fact, India has already begun to act. Over the past decade, its public capital expenditure has grown more than fourfold, highway construction speed has risen from about 12 kilometers per day to about 34 kilometers per day, and the national highway network has expanded by about 50%. This is just the beginning.

Electrification: More Than Carbon Reduction

After a brief setback, the global electrification process is accelerating again. From March to June 2026, global electric vehicle sales grew 5% year-on-year, with penetration exceeding one-fifth. Compared with internal combustion engine vehicles, EVs use about three times as much copper—this is one of the core pillars supporting long-term optimism about copper demand.

In the past, electrification was driven mainly by decarbonization goals. But the energy crisis in recent years has changed this logic: reducing dependence on fossil fuels and enhancing energy autonomy have become new drivers. When energy security converges with climate goals, the demand curves for copper and steel become steeper.

Uranium and Potash: Overlooked Accelerators

In the market spotlight, copper and iron ore have always been the protagonists. But BHP's outlook reminds us that the resource demands of the future world are diversified.

Uranium's position is quietly changing. Energy security concerns, the practical pressures of net-zero targets, and advances in SMR technology have made nuclear power a viable option for many countries again. For uranium miners, this is a structural tailwind.

Potash serves another grand narrative: global population growth and food security. With limited arable land, raising per-unit yield is an inevitable choice, and potash is an indispensable input in that process.

The End of the Old Model and the Establishment of a New Paradigm## The End of the Old Model and the Establishment of a New Paradigm

For a long time, commodity investors were accustomed to using a single variable—China's demand—to forecast prices. That was a relatively simple world: the industrialization process of one super-economy determined the fundamentals of copper, iron ore, and coal.

The current world is more complex and more resilient. China remains important, but has shifted from the primary engine of incremental growth to a mature, stable demand center. India is now taking up the baton to launch its own large-scale infrastructure construction. Meanwhile, AI and data centers are creating an entirely new demand curve—completely different from the traditional real estate and infrastructure cycles—one driven by global tech giants' capital expenditure, not by urbanization built on steel and concrete.

This is precisely the historic turning point for commodity markets: demand is no longer dependent on a single country or a single use, but is jointly supported by structural forces from multiple dimensions. Traditional cyclical attributes are weakening, while long-term growth attributes are strengthening.

For resource companies, this means a fundamental shift in strategic focus. Companies with diversified product portfolios—steel raw materials, copper, uranium, potash—will be better able to adapt to this multipolar demand structure. In an era of uncertainty, this diversity itself is a form of risk resilience and a bet on long-term trends.

Conclusion: The World Needs More Metals, Not Fewer

From AI data centers in Silicon Valley to highway networks in Delhi, from grid upgrades in Texas to mine expansions in South Africa, the physical foundation of the global economy is undergoing a systematic reinforcement with metals.

This is not about short-term market fluctuations, nor a simple replay of a new commodity supercycle. It reflects a deeper structural change: the materialization of digital civilization, the decarbonization of energy systems, and the diffusion of global economic gravity toward emerging markets such as India.

The logic of commodities has changed. It is no longer a relic of the "old economy," but an irreplaceable raw material for building the future world. Investors and companies that can clearly perceive this structural trend will gain a first-mover advantage in the coming decades.

The world is being rebuilt. And rebuilding requires metals.
