Copper prices have climbed 15% in 2026, trading near record highs on the London Metal Exchange. The rally is driven by rising demand from AI data centers, which need large amounts of copper for electrical infrastructure, and from broader electrification efforts like grid expansion, renewables, and EVs. S&P Global projects copper demand will grow from about 28 million metric tons in 2025 to 42 million by 2040, a 50% increase, while supply may fall short by 10 million tons annually by 2040. Data centers alone could consume up to 2.5 million tons of copper per year by 2040, up from 1.1 million in 2025. Each megawatt of data center capacity requires 30 to 40 tons of copper, meaning a 100 MW facility needs several thousand tons. This demand is not just about AI servers; it includes substations, transformers, cabling, and grid connections. For investors and policymakers tracking the clean energy transition, copper is a critical material. Its price and supply outlook affect the cost of grid upgrades, renewable projects, and electric vehicles. The article provides a clear breakdown of the demand drivers and the supply gap, making it a useful read for anyone involved in climate finance or energy infrastructure.

The copper story is a good reminder that the energy transition is a materials story too. Grid buildout and EV charging alone will eat a lot of copper. The AI angle just adds more pressure on supply. Worth reading for anyone tracking clean energy supply chains.

The 30-40 tons per MW figure for data centers is interesting. But that's just the facility itself. You also need transmission and substations to feed it. That's where the real copper demand shows up. I'd like to see a breakdown of how much is inside the data center vs. the grid connection.

The S&P supply shortfall estimate of 10 million tons by 2040 is a big number. But it depends on how fast permitting and recycling scale. If we don't fix the permitting process for mines and grid upgrades, the shortfall could be worse. Policy matters as much as market signals here.

Copper is also a big deal for building electrification. Heat pumps, EV chargers, and panel upgrades all need it. The article focuses on AI and data centers, but the residential and commercial retrofit market is a steady, less flashy source of demand. That part might be underappreciated.

I think the key takeaway is that copper demand is not a bubble. It's tied to actual infrastructure that has to be built. The question is whether supply can keep up. The article does a good job of breaking down the numbers, especially the per-MW copper intensity.
