My neighbour runs a data centre consultancy in Leeds, and last month he mentioned something that caught my attention. His clients are scrambling to secure copper supplies for upcoming AI infrastructure projects, often willing to pay whatever the market demands. It’s a stark reminder that we’re witnessing something extraordinary artificial intelligence isn’t just changing software, it’s fundamentally reshaping copper demand in ways most investors haven’t fully grasped yet.

Copper Prices: Understanding the AI-Driven Supercycle

The numbers tell quite a story, don’t they? London Metal Exchange copper recently topped £9,600 per tonne, marking a 42% increase over the previous year. What’s driving this remarkable surge? According to Wood Mackenzie’s research, global copper demand is projected to jump 24% by 2035, with AI infrastructure playing a critical growth role.

Here’s something that might surprise you. A conventional data centre uses between 5,000 and 15,000 tonnes of copper. But the new generation of AI hyperscale facilities? They can require up to 50,000 tonnes of copper per facility more than three traditional centres combined. That’s extraordinary when you think about it.

J.P. Morgan projects copper prices averaging around £9,700 per tonne for the full year, whilst UBS takes an even more optimistic stance, forecasting £10,400 by year’s end. Goldman Sachs, typically more conservative, expects prices to remain in the £8,000 to £8,800 range for 2026, though they’re predicting £12,000 per tonne by 2035.

The supply side presents an equally compelling picture. BloombergNEF estimates the copper shortfall could reach 19 million tonnes over the next 25 years without new mines or significant recycling gains. And opening new copper mining operations isn’t quick it takes over a decade from discovery to first production. Meanwhile, disruptions in Chile, Indonesia, and Peru continue tightening available supply.

What makes this particularly interesting for those investing in copper is the inelastic nature of data centre demand. Developers will pay whatever it costs to secure copper, as it represents a tiny fraction of total project budgets. When you’re building a £500 million AI facility, spending an extra few per cent on copper doesn’t matter you need the infrastructure regardless.

Investing in Copper: ETFs vs Physical vs Mining Stocks

So you’re convinced about copper’s potential. The question becomes: what’s the best way to gain exposure? UK investors face some unique considerations here, and I’ve seen people make costly mistakes by not understanding their options properly.

Copper mining stocks remain the most straightforward route for UK investors. Companies like Glencore, Antofagasta, and Central Asia Metals all trade on the London Stock Exchange. Glencore is particularly interesting they’re targeting production of 1.6 million tonnes by 2035, nearly doubling current output levels. They’ve also acquired recycling assets to develop “secondary supply” channels, which could prove valuable as primary sources become constrained.

The beauty of mining stocks is the double leverage effect. When copper prices rise, not only does the company’s existing production become more valuable, but increased output amplifies profits further. A 20% rise in copper prices can translate to substantially larger gains in mining company valuations.

Exchange-traded funds offer broader diversification without picking individual winners. Whilst the UK doesn’t have domestic copper ETFs, British investors can access international options like the Global X Copper Miners ETF through platforms supporting overseas investments. This fund holds 41 different mining companies, spreading risk across multiple geographies and operators.

Some investors prefer physically-backed copper funds. The Sprott Physical Copper Trust invests substantially all its assets in physical copper, offering direct price exposure without the operational risks of individual miners. It’s worth noting these international investments fall under the RBI’s Liberalised Remittance Scheme, so factor in those considerations.

Physical copper ingots present a different proposition entirely. A Reddit user recently shared their experience purchasing a 1kg copper bar for £31 when melt value was only around £7. That’s a 340% premium quite shocking when you think about it. Unlike gold or silver with established dealer networks and reasonable premiums, copper ingots face substantial markups.

Why such high premiums? Manufacturing costs, certification expenses, limited dealer networks, and storage requirements all contribute. More problematically, selling copper ingots typically means approaching scrap yards that pay near melt value, completely erasing your initial premium. Unless you’re purchasing artisan pieces with collector appeal what some communities call “The Precious” physical copper rarely makes financial sense as an investment vehicle.

For most UK investors, copper exposure through mining company shares or ETFs offers superior liquidity and lower transaction costs than physical holdings. If you’re genuinely interested in physical copper, understand the buy-sell spread thoroughly before committing capital.

Copper Ingots vs Copper Companies: Where Smart Money Goes

Let’s talk about something that often gets overlooked. When evaluating copper investments, you’re essentially choosing between passive metal ownership (ingots) or active business operations (companies). The distinction matters more than many realise.

Copper companies generate cash flow. They pay dividends. They can expand production, improve efficiency, acquire new assets, and adapt to market conditions. Glencore, for instance, isn’t just mining copper they’re also operating smelters, refineries, and recycling facilities whilst serving as intermediaries between producers and consumers. That diversified revenue stream provides resilience beyond simple commodity exposure.

Physical copper ingots, conversely, offer only one profit pathway: price appreciation. There’s no cash flow, no dividends, no productivity improvements. You’re entirely dependent on copper prices rising sufficiently to overcome your initial premium and eventual selling costs.

I’ve noticed discussions on UK investment forums where people debate copper coins versus copper plates versus standard ingots. Whilst coins sometimes carry numismatic value beyond metal content, standard industrial copper ingots rarely appreciate beyond spot price movements. The storage requirements alone copper is dense and bulky make large holdings impractical for most individual investors.

Here’s another consideration. Copper companies can hedge their production, lock in favourable prices, and adjust output based on market conditions. As an individual holding physical copper, you have none of these options. You’re fully exposed to spot price volatility without any operational levers to pull.

The exception might be artisan copper pieces with genuine collector appeal. Limited-run items from recognised coppersmiths sometimes maintain premiums through both metal appreciation and collectible demand. But these fall into a different category entirely more akin to art collecting than metals investing.

For serious investors focused on the AI infrastructure buildout, copper companies provide leveraged exposure to rising prices whilst generating interim cash flows. The operational expertise these firms bring particularly in navigating permitting, environmental regulations, and geological challenges adds value beyond mere commodity ownership.

KPS Tools: Tracking Copper for Sale Opportunities

Timing matters tremendously when investing in copper, particularly given the metal’s volatility. A single mine disruption can trigger double-digit price spikes overnight, as we saw with the 2025 mudslide at Indonesia’s Grasberg mine. Having reliable, real-time copper price tracking becomes essential.

This is where the Karat Purity Scale platform proves genuinely valuable. Rather than manually checking the London Metal Exchange, local dealers, and financial news throughout the day, KPS consolidates critical information in one location. For professionals managing copper for sale inventories or tracking copper concentrate pricing, this saves substantial time whilst reducing costly misjudgements.

Consider a coppersmith in Birmingham purchasing raw materials for custom architectural work. Locking in copper plates or copper coins at the wrong time could significantly impact project profitability. Real-time price monitoring allows strategic purchasing when prices dip rather than buying at peak levels.

KPS tracks both refined copper and various intermediary forms copper concentrate, copper plates, even specialty items. This breadth matters because different markets move at slightly different rates. A manufacturer sourcing copper for sale might find arbitrage opportunities between scrap markets and refined products.

The platform also provides historical context. Understanding seasonal patterns, long-term trends, and how specific events (mine strikes, trade policies, demand surges) affected prices previously helps inform current decisions. When you see copper prices spike 15% in a week, is that a buying opportunity or the start of a sustained rally? Historical data provides perspective.

For investors tracking copper companies, KPS helps correlate stock price movements with underlying commodity shifts. If a mining company’s shares lag copper price increases, that might signal operational issues worth investigating. Conversely, shares outpacing metal prices could indicate the market’s anticipating production growth or improved efficiency.

Regional price variations also matter more than many assume. UK copper prices don’t always mirror London Metal Exchange benchmarks exactly local supply-demand dynamics, currency fluctuations, and transportation costs all create variations. KPS helps navigate these nuances across different markets and regions.

Whether you’re evaluating copper mining operations for investment, sourcing materials for industrial applications, or simply tracking broader commodity trends, having consolidated, accurate pricing information streamlines decision-making considerably during this AI-driven supercycle.

Frequently Asked Questions

How is AI affecting copper prices in 2026?

AI infrastructure has emerged as a major demand pillar, with data centres requiring copper for power lines, transformers, and cooling systems. Modern AI facilities require 3 to 5 times more copper than traditional data centres. With nearly 100 gigawatts of new data centre capacity expected between 2026 – 2030, copper demand could reach 572,000 tonnes annually by 2028 roughly equivalent to adding another Chile to global annual demand. This structural shift is supporting higher copper prices alongside traditional industrial uses.

Should I invest in physical copper ingots or mining stocks?

For most UK investors, copper mining stocks offer superior returns compared to physical copper ingots. Mining companies provide dual profit pathways rising copper prices and increased production whilst physical ingots profit only from price appreciation. Physical copper also carries substantial premiums (often 300% or more over melt value) and poor resale liquidity, as scrap yards typically pay near spot prices. Unless purchasing artisan pieces with collector value, copper exposure through Glencore, Antofagasta, or diversified ETFs typically delivers better risk-adjusted returns than physical holdings.

Where can I track copper prices in the UK?

The London Metal Exchange provides global benchmark pricing, whilst platforms like KPS (Karat Purity Scale) offer consolidated tracking of copper prices across different forms and regions. KPS monitors refined copper, copper concentrate, copper plates, and copper for sale in scrap markets, providing real-time updates and historical context. For UK investors and businesses, this eliminates manually checking multiple sources throughout the day whilst helping identify regional pricing variations that create opportunities.

What are the best copper companies to invest in for 2026?

UK investors can access copper through London Stock Exchange listings including Glencore (targeting 1.6 million tonnes production by 2035), Antofagasta (a dedicated copper miner with Chilean operations), and Central Asia Metals (focused on Kazakhstan’s Kounrad asset). Alternatively, international copper ETFs like Global X Copper Miners ETF provide diversified exposure to 41 mining companies globally. Given current AI-driven demand growth and supply constraints, analysts favour companies with expansion capacity and low production costs over those facing declining ore grades.

Why are copper prices expected to remain high through 2026?

Copper faces a structural supply-demand imbalance. Supply constraints from mine disruptions in Chile, Indonesia, and Peru are tightening markets, whilst new mines take 10+ years to develop. Meanwhile, demand is accelerating from AI data centres (requiring up to 50,000 tonnes per facility), electric vehicles (using 2-4 times more copper than petrol cars), and renewable energy infrastructure. Investment banks project prices averaging £9,700 to £10,400 per tonne through 2026, with Goldman Sachs forecasting £12,000 by 2035 as the supply deficit widens.
