AI infrastructure capex race sparks chip and copper crunch

The explosive growth in AI data center spending is colliding with real constraints on the materials needed to build that infrastructure. Multiple sources flag that copper, used in power distribution, transformers, and grid expansion for mega-facilities, is becoming scarce; one analyst noted that hyperscale facilities require roughly 27 tonnes of copper per megawatt. Copper futures have pushed toward three-month highs near USD 13,619 per tonne, only 6% below January's all-time peak. Simultaneously, DRAM and NAND memory chips are facing severe allocation pressure, with lead times stretching and spot prices rising as AI customers prioritize aggressive inventory builds.

Memory makers like Micron, SK Hynix, and Samsung are operating at or near full capacity, and supply is not expected to ease materially until late 2026 or beyond. Some China export bans on sulphuric acid, a critical input for semiconductor and copper refining, have exacerbated the squeeze, forcing price increases both at the component level and in the raw materials markets. Silver, typically an industrial afterthought, has jumped to two-month highs as its use in power electronics and battery systems has spiked alongside data center buildouts. Traders are viewing memory and precious metals as de facto inflationThe rate at which prices rise across an economy. hedges on AI infrastructure demand.

The potential risk is a self-reinforcing cycle: if supply continues to lag demand, capex timelines slip and project returns deteriorate, which could cool spending just as investors have begun to price in exponential data center growth through 2027. Hyperscalers may begin to rationing or delay buildouts, signaling to the market that the AI capex boom is no longer as frictionless as consensus models assume. Alternatively, if prices remain elevated long enough, customers may seek alternative materials or designs, reducing the bottleneck effect but also dampening the winners in the commodity complex.

Commodity investors are hedging by rotating into copper miners and silver futures. However, skeptics point out that most of the data center capex cycle was already in the pricing as of April; current shortages may represent a brief friction point rather than a structural cap on growth.
