Dr. Copper Says the AI Boom Is Spreading Through the Real Economy
The clearest evidence this week that the artificial intelligence buildout has moved beyond the stock market and into the physical economy did not come from a chip company like Nvidia Corp. or Micron Technology Inc.
It came from a metal that humans have been smelting for roughly 10,000 years.
Copper set an all-time high on the London Metal Exchange on Tuesday, touching $14,617 a metric ton in a second consecutive record session.
On the Comex exchange in New York, front-month copper futures traded near $6.81 a pound, 20% higher than the $5.68 at which the metal closed in 2025.
Wall Street calls it “Dr. Copper” because the metal is used in almost everything that carries electricity, which has historically made its price a reliable indicator of global industrial health.
The doctor is not sending a subtle message right now.
Where The Copper Deficit Is Coming From
Copper is the backbone of an AI data center.
High-density server racks are powered by thick copper busbars rather than conventional cabling, and the liquid cooling systems required by advanced chips use copper tubing and heat exchangers.
The bigger draw sits outside the fence, in the substations and transmission lines needed to feed campuses that draw hundreds of megawatts.
J.P. Morgan has estimated that a single large AI data center can require up to 50,000 metric tons of copper, and that data centers, as a category, will consume roughly 475,000 metric tons in 2026.
Supply is not cooperating.
Chile, the world’s largest producer, recorded its weakest second-quarter output in at least 19 years and cut its full-year forecast for a second straight quarter, now expecting a 2.6% decline.
The Factory Data Backs It Up
A metal price alone can be a squeeze. Two data points in the same week are harder to dismiss.
The J.P. Morgan Global Manufacturing PMI rose to a three-month high of 52.3 in August, up from 52.1 in July.
The purchasing managers’ index is a monthly survey of executives who actually buy raw materials, where a reading above 50 indicates activity expanded from the prior month. August marked the 13th consecutive month above that line.
In the United States, the Institute for Supply Management’s manufacturing index registered 54.6% in August, an eighth straight month of expansion, with the production sub-index at a robust 58.3.
The Market Has Already Noticed
Copper equities have been running well ahead of the broad market all year. Freeport-McMoRan Inc. (NYSE:FCX) is up 43% year to date through Friday’s close, Southern Copper Corp. (NYSE:SCCO) 42% and Teck Resources (NYSE:TECK) 44.3%.
The Global X Copper Miners ETF (NYSE:COPX) has gained 26%, and the United States Copper Index Fund (NYSE:CPER) has gained 14.3%. The SPDR S&P 500 ETF Trust (NYSE:SPY) is up 12.9% over the same stretch.
All five moved higher again in Tuesday’s premarket session, with Freeport-McMoRan quoted around $75.09 and Teck Resources near $71.77.
