AI Metals Scoreboard: Data Center Share of Each Market

The short answer: in every case data centers take a single-digit percentage of the market: silver about 3.8%, copper under 2% and aluminum about 1%. Uranium is shown separately because its figure is a different measure: our estimate of added fuel for the extra nuclear generation the IEA expects by 2035 is about 5.5% on top of today's reactor requirements. Of the three metals measured the same way, silver is the most exposed by share. By dollars, copper is the largest, at $7 billion a year at the latest price against $3 billion for silver.

Educational only, not financial advice. Each figure comes from the metal's own guide, linked below, with its source and year. The years differ, so the shares are an order of magnitude, and the uranium figure is not part of the ranking. The snapshot table and the chart are refreshed about every six hours.

A snapshot, not a live quote: Yahoo Finance daily prices, each asset's latest bar dated (UTC) Copper 6 Oct 2026, Silver 6 Oct 2026, Aluminum 6 Oct 2026, Uranium (URA ETF) 6 Oct 2026. Refreshed about every six hours and last computed on 6 Oct 2026 at 20:25 UTC. Each price is the latest daily bar and each return runs to it. Price changes only, in US dollars, without dividends or fees. Futures are continuous front-month contracts, so a contract roll can show as a small step. Volatility is the standard deviation of daily moves over the past year, annualized. The highest close is from monthly history, not the intraday record.

Silver's share is of forecast total demand; copper's and aluminum's are of world output; uranium's is of reactor requirements. The data center figure for each metal comes from a different publisher and year, so this is an order of magnitude and not a precise ranking. The inputs for each row are on that metal's guide.

• Silver (2026) about 3.8%
• Copper (by 2030) under 2%
• Aluminum (at its peak) 0.8% to 1.2%

Different years and publishers, so read it as an order of magnitude. Silver is a share of forecast total demand; copper and aluminum are shares of world output. Uranium is left out because its estimate measures added fuel for new reactors, not total data center use.

Prices only, without dividends or fees. Copper, silver and aluminum are futures contracts. The uranium line is the URA ETF, which holds uranium miners and nuclear-related companies, so it is a proxy and not the uranium price. A metal's price moves on much more than AI.

• AI is a single-digit share of every one of these markets. From about 1% for aluminum to about 3.8% for silver, and even uranium's added-fuel estimate is about 5.5%, so none is mainly an AI story yet.
• Among the metals measured the same way, the smaller market is the more exposed. Silver (about 1.1 billion ounces of demand) ranks above copper and aluminum, which are far larger.
• Copper is the biggest by dollars. At the latest price its data center demand is worth $7 billion a year, against $3 billion for silver.
• The roles differ. Silver goes inside the hardware, aluminum into cooling and racking, copper into the power wiring, and uranium is fuel for reactors that may supply the electricity.
• The uncertainty is not equal. Silver's figure is a named forecast, copper's and aluminum's are published estimates, and uranium's is our own derivation of added fuel, a different kind of number, which is why it is kept out of the ranking.

If you want one idea from the whole AI and metals story, it is this: AI takes a single-digit percentage of each metal's market. Of the metals measured the same way, silver is the most exposed by share, copper is the largest by dollars, and aluminum is the least exposed. Uranium is a separate estimate of added fuel for new nuclear generation by 2035, not a like-for-like share. That does not make AI unimportant, since demand growth at the margin can move prices, but it means a metal's price is driven by far more than AI. Use the share table to check a claim before accepting it, and the snapshot table to see how each has actually traded, which is history, not a forecast.

Which metal is most exposed to AI?

Among the metals measured the same way, silver (about 3.8% of forecast 2026 demand), then copper (under 2% of refined output by 2030), then aluminum (about 1% at its peak). Uranium is a separate estimate: the extra nuclear generation the IEA expects for data centers by 2035 would need about 5.5% more fuel than reactors use today, which is added demand and not comparable to the others. By dollar size, copper is the largest at the latest prices. No metal is mainly an AI story: in each case data centers take a single-digit percentage.

How much of the world's silver do data centers use?

The Silver Institute's World Silver Survey 2026 expects data centers to account for more than 10% of electrical and electronics silver demand in 2026, more than 42.3 million ounces, which is about 3.8% of the 1,110 million ounces of forecast total silver demand.

How much copper do data centers use?

The IEA expects data centers to use more than half a million tonnes of copper a year by 2030, under 2% of the roughly 29 million tonnes of refined copper the world produces. The Copper Development Association estimates up to 50,000 tonnes for one hyperscale AI data center.

How much aluminum do data centers use?

Wood Mackenzie estimates aluminum use inside data centers peaks at 0.6 to 0.9 million tonnes a year, about 1% of the 74 million tonnes of primary aluminum produced worldwide, mostly in cooling systems and racking.

How much uranium do data centers need?

No source publishes it, so this is our estimate of added demand. The IEA expects nuclear to add about the same generation for data centers as natural gas, 175 terawatt-hours, by 2035, which at a 90% capacity factor is about 22 gigawatts of reactors and about 3,800 tonnes of uranium a year, roughly 5.5% on top of the 68,920 tonnes the world's reactors required in 2025.

Why do the shares use different years?

Because the publishers report different years. The Silver Institute gives 2026, the IEA gives 2030 for copper and Wood Mackenzie gives aluminum's peak in the early 2030s. The uranium figure is our estimate of added demand by 2035. The table is meant to show the order of magnitude, not a precise ranking, and each metal's own guide shows the inputs.
