Copper surges to record highs as AI infrastructure demand tightens supply

Industrial metals are rallying as the confluence of AI infrastructure capex, post-conflict commodity supply tightness, and traditional infrastructure spending collide. Copper just pushed to $13,619/ton on the LME, a fresh 3-month high and only 6% below the January all-time peak near $14,500. Traders note that the copper market is starting to look tight again, with inventory pressures and production constraints in key regions creating pricing power for producers.

The demand driver is AI data center cooling systems, power distribution, and cabling; each megawatt of data center capacity requires substantial copper inputs. Manufacturers including Broadcom and Nvidia ecosystem suppliers are signaling that copper and other industrial metals will be critical bottlenecks in the race to build out AI infrastructure. Some analysts point to a parallel with semiconductor supply chains: just as chip capacity became scarce, industrial metals supply is becoming more constrained.

Supply risks are compounded by geopolitical and weather disruptions. The Iran conflict has disrupted logistics and refinining; South American mining operations face labor and permit challenges. Iron ore has also rallied on steady Chinese demand, hitting the highest since October 2024. The emerging narrative suggests that industrial metals and commodities will see sustained pricing power through 2026 as AI capex, reconstruction spending, and supply shocks align.

The main risk is demand destruction if AI capex growth decelerates or if economic growth stalls. A sharp recession would cause copper and other metals to correct sharply. Additionally, if supply issues are resolved more quickly than expected or if substitution materials are adopted, the tight supply narrative could unwind.
