Power infrastructure linking an AI data center campus with the wider electricity grid.
Copper’s 2026 outlook is being shaped by two forces moving at different speeds. Demand is gaining structural support from artificial intelligence infrastructure, electricity networks and broader electrification. Mine supply, meanwhile, remains exposed to declining ore grades, project delays, operational disruptions and long permitting timelines.
That tension is keeping the copper market highly sensitive to relatively small changes in demand, inventories and trade policy. Forecasts for 2026 range from a modest surplus to a meaningful deficit, while price expectations cluster broadly between $11,000 and $12,500 per metric ton. A more severe supply squeeze could push prices toward $13,000–$15,000 per ton, while weaker industrial demand and a faster scrap response could pull prices closer to $10,000–$11,000.
The central question for operators and investors is not whether AI will use copper. It is whether new mine supply and available inventories can keep pace with the speed of investment in power infrastructure.
AI is adding copper demand through the power system
AI-related copper demand is broader than the wiring inside a data center. Copper is used across the electrical chain, including:
- Power-generation connections
- Transmission and distribution networks
- Transformers and substations
- Data-center busbars and cabling
- Cooling systems and heat-management equipment
- Backup power systems and battery infrastructure
- Construction and grid interconnection equipment
The International Energy Agency has described the global economy as entering an “Age of Electricity,” with grids, industry, transport, data centers and buildings all requiring more power infrastructure. That creates a copper demand profile tied not only to computing capacity but also to the network required to deliver electricity to that capacity.
S&P Global expects global copper demand to rise from approximately 28 million tons in 2025 to 42 million tons by 2040. Its analysis also places data-center copper demand at about 1.1 million tons in 2025, rising to 2.5 million tons by 2040.
The near-term growth rate is less dramatic than the long-term change, but it is still material. The International Copper Study Group expects refined copper usage to grow 1.6% in 2026, while other estimates place total demand growth closer to 2.6%. Even the lower estimate represents a substantial volume increase in a market where supply additions are difficult to deliver quickly.

Grid investment may matter more than servers
Data centers are visible symbols of AI demand, but grid investment may be the more important copper story.
Large facilities require new substations, high-voltage connections, backup generation and distribution upgrades. In some regions, transmission capacity is already limiting the speed at which data-center projects can connect to the grid. That creates a second wave of infrastructure spending beyond the data center itself.
The same dynamic applies to electric vehicles, renewable power, industrial electrification and heat pumps. Each application adds demand for conductors, transformers, switchgear and network upgrades. The result is a more diversified demand base than a simple technology cycle.
This does not mean every announced AI project will be built on schedule. High interest rates, permitting constraints, local opposition and power availability could delay some facilities. However, the capital already committed to power infrastructure can continue supporting copper demand even if individual data-center projects are deferred.
Mine supply remains the market’s main constraint
The supply side is less flexible. New copper mines often require a decade or more from discovery to commercial production. Existing mines face declining grades, deeper ore bodies, water constraints, higher operating costs and more complex permitting requirements.
The IEA’s Global Critical Minerals Outlook has warned that the current project pipeline points to persistent copper supply deficits through 2035. The agency has also highlighted the difficulty of developing new mines quickly enough to meet energy-transition demand.

Operational disruptions can therefore have an outsized market impact. A weather event, pit-wall failure, labor dispute, processing bottleneck or delayed expansion may remove more copper from the market than expected. Recent market commentary has pointed to reduced output guidance and disruptions at major operations as reasons for a tighter 2026 balance.
The market is also dealing with constraints beyond mined ore. Concentrate availability has tightened, putting pressure on smelter treatment charges. Lower treatment charges can indicate that smelters are competing for limited concentrate, even when refined-metal inventories appear more comfortable.
Skillings previously examined this dynamic in “Copper Supply: Mine Output Falls as Smelter Fees Hit Zero”. The issue is important because a copper mine can produce concentrate without guaranteeing that enough smelting capacity, reagents or logistics are available to convert it into refined metal.
Tariffs are reshaping regional availability
Trade policy adds another layer of uncertainty. Potential U.S. tariffs on refined copper and copper products have encouraged buyers to move material into the United States ahead of possible policy changes.
That has created a two-speed inventory picture:
- U.S. exchange inventories may appear relatively well supplied.
- Stocks outside the United States can remain tighter.
- Regional premiums may diverge as metal is redirected.
- Import-dependent consumers may face higher replacement costs.
- A later tariff decision could reverse some stockpiling flows.
Goldman Sachs Research has argued that tariff uncertainty can temporarily support prices by encouraging U.S. stockpiling and reducing availability elsewhere. Its published base case anticipated a 15% tariff on refined copper, with implementation timing a key variable. Once policy becomes clearer, the market may return its attention to demand growth, scrap supply and the underlying global balance.

The effect will not be limited to the United States. Any change in trade flows can alter regional premiums, warehouse withdrawals and the economics of arbitrage. For manufacturers, the practical risk is not only the benchmark copper price but also the cost and availability of nearby units.
2026 copper price forecast: base, bull and bear cases
The range of published forecasts reflects genuine uncertainty rather than simple disagreement. The difference between a 100,000-ton surplus and a 300,000-ton deficit is small relative to global consumption, but it can be significant when inventories are low or concentrated in the wrong region.
| Scenario | 2026 average price range | Transparent assumptions | Main risk |
|---|---|---|---|
| Base case | $11,500–$12,500/t | Refined demand grows roughly 1.6%–2.6%; mine disruptions remain manageable; the market is near balance; U.S. tariff policy becomes clearer; non-U.S. inventories remain relatively tight | Macro slowdown limits demand and high prices encourage scrap |
| Bull case | $13,000–$15,000/t | A 300,000-ton-plus deficit develops; major mine disruptions persist; grid and AI investment remains strong; tariff-related stockpiling continues; regional inventories tighten further | Demand destruction and substitution accelerate |
| Bear case | $10,000–$11,200/t | Refined-market surplus reaches roughly 300,000 tons; Chinese and global industrial demand weakens; scrap supply rises; tariff uncertainty fades; project output is better than expected | Supply disruptions reappear and inventories fall quickly |
The base case is the most defensible operating assumption. Reuters’ analyst poll placed the 2026 median forecast near $11,975 per ton, while S&P Global and Deutsche Bank forecasts were also above $12,000. These estimates reflect a market that is tight but not necessarily facing an immediate physical shortage.
The bull case depends less on extraordinary demand growth than on supply failure. Citi and J.P. Morgan have outlined upside scenarios above $13,000, particularly if low inventories coincide with mine disruptions and strong first-half demand.
The bear case is supported by Goldman Sachs’ expectation of a roughly 300,000-ton surplus in 2026. High prices could suppress consumption, encourage substitution and bring additional scrap into the market. A weaker Chinese construction and manufacturing cycle would also weigh on refined demand.
What decision-makers should monitor
For miners, fabricators, utilities and investors, the most useful indicators are likely to be:
- Treatment and refining charges: Further weakness would signal intense competition for copper concentrate.
- Regional warehouse spreads: The gap between U.S. and non-U.S. inventories will reveal whether tariff-driven dislocation is persisting.
- Chinese physical demand: Import flows, fabricator activity and inventory withdrawals can quickly change the market balance.
- Grid-connection approvals: These provide a more reliable measure of AI-related copper demand than data-center announcements alone.
- Scrap flows: Higher prices can unlock secondary supply, especially in mature industrial markets.
- Mine guidance and project milestones: Delays at expansions and new developments can matter more than small changes in short-term demand forecasts.
Copper’s 2026 outlook therefore rests on a narrow balance. AI and grid investment are creating durable demand, but prices will depend on whether that demand arrives faster than mines, smelters, scrap markets and trade networks can respond.
For operators, the implication is a continued premium on reliable production, processing flexibility and power access. For investors and policymakers, the key risk is that a market appearing close to balance can tighten rapidly when regional inventories are fragmented and supply disruptions occur.
