Inside Copper's Historic Rally: From Mine Collapses to AI Data Centers

This disaster compounded a pre-existing landscape of fragility:

• Chile's structural decline: The world’s top copper producer has been battling falling ore grades and water scarcity for years, tightening global concentrate availability .
• Further disruptions: Worker protests in Peru, operational issues in the Democratic Republic of Congo, and a sulfuric acid shortage have all layered additional strain onto the global supply chain .

On top of these physical constraints, a trade-policy dislocation supercharged the price surge. Fears of proposed Section 232 tariffs on copper (announced at 50% in July 2025) triggered a massive preemptive rush to move physical metal into the United States. More than 650,000 tonnes of copper was shipped into US warehouses, concentrating nearly two-thirds of the world’s visible stocks domestically and draining inventory from exchanges like the LME and COMEX .

The Demand Revolution: An AI-Fueled Appetite

While mines failed, demand did not wait. The infrastructure buildout for a new generation of technology created a structural demand floor that did not exist in previous decades.

• AI data centers are a primary new consumer. A single large-scale facility can require up to 50,000 tonnes of copper for its wiring, power distribution, and cooling systems . S&P Global forecasts indicate that copper demand from data centers is set to more than double by 2030 .
• The “triple threat” of data centers, electric vehicles (which use three to four times the copper of combustion-engine cars), and grid modernization has created a demand profile that CME Group analysts say has “fundamentally altered the market’s demand profile” .
• Macroeconomic tailwinds from the Federal Reserve’s 2025 easing cycle—three consecutive quarter-point rate cuts—weakened the US dollar and drew speculative capital into commodities, further fueling the rally .

Investors have noticed. Shares of major producers like Freeport-McMoRan and BHP hit all-time highs as the market priced in sustained pricing power and scarcity for the foreseeable future.

The Great Divide: What Major Banks See Next

The outlook for copper through the end of 2026 is not a settled narrative. Wall Street is engaged in a high-stakes standoff between those who see a speculative bubble and those who believe in a new structural paradigm.

As of June 2026, the key forecasts have shifted dramatically:

• Goldman Sachs raised its year-end price target to $13,735 per tonne, up more than 10% from its prior call, explicitly citing the downward revision to mine supply from the Grasberg aftermath . Crucially, however, the bank remains cautious. It expects the rally to face a significant “bearish correction” in the second half of 2026 as speculative positions cool and clarity emerges around US tariff policy .
• Citigroup has taken a structurally bullish turn for the first time in 2026, forecasting a new high of $15,000 per tonne within a year. Citi’s analysts argue that a “strategic ambiguity” around US tariffs, combined with unrelenting demand from AI and the energy transition, is creating a durable deficit that will support elevated prices .
• JP Morgan largely mirrors Citi’s confidence, citing similar drivers of grid upgrades, defense spending, and electrification .

The divergence is stark. Goldman Sachs points to an underlying market surplus that has been masked by speculative frenzy and tariff-driven hoarding, arguing that once trade flows normalize, prices could quickly retreat toward $11,000–$12,000 per tonne . Citi and other bulls counter that the physical disruption—especially the loss of millions of tonnes of output from an irreplaceable mine like Grasberg—has structurally shifted the balance into a deficit that will take years to resolve .

Copper has become the defining commodity of a new era, where the physical demands of building an electrified, AI-powered economy are colliding in real time with geopolitical risk and industrial fragility. The only certainty is continued volatility.
