When speculative enthusiasm outpaces underlying physical reality, the market becomes more fragile. 2026 has already seen such a pattern play out with Bitcoin, U.S. natural gas, gold, silver…

Even crude oil is showing similar symptoms, although with far stronger geopolitical implications. But according to experts, copper may be next in line to face such a risk.

The risk is particularly important because copper has carried one of the strongest structural stories in commodities. Electrification, renewable power, grid expansion, electric vehicles and artificial intelligence infrastructure have all been used to justify higher prices.

A softening industrial picture, a rising correlation with U.S. technology stocks and vulnerability to equity market drawdowns all suggest that copper's future has not yet arrived.

Front-Running the Demand

Financial infrastructure provider StoneX believes the current copper rally has had the investment narrative shift well ahead of physical demand.

"The quantity of demand is less than 2% for copper stemming from AI and data centers," Natalie Scott-Gray, senior metals analyst, wrote, highlighting the gap between enthusiasm and actual consumption.

That figure matters because AI has become one of the dominant explanations for copper's resilience. The metal is trading around $6.19 per pound, up 8.35% year-to-date. It is outpacing the Global X Copper Miners ETF (COPX), which is up 7.42% in the same period.

StoneX also notes that copper's correlation with U.S. technology stocks has reached its highest level since 2012. The correlation makes the metal unusually sensitive to shifts in technology-sector sentiment.

The concern is not that copper lacks long-term demand support, but that speculative capital has aggressively front-run that support, leaving prices exposed to abrupt corrections.

Stock Market's Sock Puppet

Mike McGlone, senior commodity strategist at Bloomberg Intelligence, views the current environment through the lens of a broader cyclical purge.

He believes that multiple markets have benefited from speculative excess and have now fallen toward supply-and-demand reality. According to a recent interview, copper might be next.

"Copper's main risk is if the stock market goes down because it's a complete sock puppet to the stock market; at this moment, it only goes up when stocks go up. When stocks go down, it goes down more," he said.

The second half of the year is therefore central to McGlone's outlook. He argues that if the U.S. stock market experiences a typical cyclical downturn, or a midterm-election correction, commodities could face "pretty severe deflation."

In that scenario, copper would be especially vulnerable. Unlike gold, which can draw on central-bank demand and reserve diversification, or oil, which has clearer inventory and supply dynamics, copper's recent strength has leaned heavily on equity-market confidence and long-term electrification assumptions.

Still, short-term weakness would not invalidate copper's long-term thesis, but for investors who are now paying a premium for demand that may arrive after years, there is little margin for disappointment.
