June 30, 2026, (Inside AI) — The global copper supply cannot meet the surging demand driven by artificial intelligence infrastructure, pushing prices to record levels. A single AI data center can consume up to 50,000 tons of copper, according to industry estimates, as hyperscale facilities multiply to support large language models and cloud computing.
Patrick Kennedy of AllSource Investments told Reuters that the mismatch between supply and demand makes copper an effective inflation hedge. His warning reflects a broader market recalibration, where the metal is now seen as a direct AI commodity play rather than just a cyclical industrial input.
Copper futures on the London Metal Exchange breached $12,000 per metric ton this month, surpassing previous peaks from the energy transition boom. The rally accelerated after major tech firms disclosed procurement plans tied to new data center campuses in Virginia, Ireland, and Singapore.
The Hidden Copper Intensity of AI Infrastructure
Data centers require copper for power distribution, cooling systems, grounding, and internal cabling. Unlike traditional server farms, AI clusters demand high-density interconnects and backup redundancy, multiplying copper use per square foot. A 2025 study by McKinsey estimated that generative AI workloads increase copper intensity by 40% compared to conventional cloud computing.
Mining analysts note that bringing new copper mines online takes 10 to 15 years on average, while AI infrastructure buildouts are measured in months. Freeport-McMoRan and BHP have accelerated exploration but face permitting delays and ore grade declines. The International Copper Study Group projects a 1.2 million ton deficit by 2028 if AI demand trends hold.
Kennedy emphasized the structural nature of the shortage.
"The world doesn't have enough copper to meet AI demand. We're looking at a multi-year supply gap that central banks can't print away."
His firm has increased copper allocations in client portfolios, betting that constrained supply will sustain elevated prices even if broader inflation cools.
Investors Pivot to Copper as an AI Proxy Trade
Hedge funds and commodity trading advisors have piled into copper futures, treating the metal as a leveraged bet on AI growth. Open interest on COMEX copper contracts hit a five-year high in June, with net long positions concentrated among macro funds. The shift mirrors earlier speculative flows into uranium and lithium during their respective booms.
However, some market veterans warn of demand destruction risks. Goldman Sachs analysts cautioned that substitution and recycling could cap upside, noting that aluminum wiring and optical interconnects may displace copper in certain data center applications. Yet these alternatives currently lack the conductivity and reliability required for high-power AI racks.
The supply crunch extends beyond mining. Smelting and refining capacity faces bottlenecks in China, which processes over 40% of global copper concentrate. Environmental restrictions and power rationing have curtailed output, adding a geopolitical layer to the supply chain. Meanwhile, the U.S. Department of Energy is funding research into copper-efficient transformer designs to ease grid constraints.
For now, the physical market remains tight. Warehouse inventories tracked by the LME have fallen to 15-year lows, and spot premiums in Shanghai signal urgent buying. As AI ambitions scale, copper's role as a critical enabler—and potential bottleneck—will likely intensify scrutiny from policymakers and investors alike.
