Copper vs Uranium: The AI Infrastructure Race

The short answer: copper and uranium meet AI at different points. Copper is in every data center, but data centers are only under 2% of the copper market by 2030. Uranium fuels the reactors that may power some of them: the extra nuclear generation the IEA expects for data centers by 2035 would need roughly 5% more fuel than reactors use today (our estimate, and a different measure from copper's). Uranium supply is also more concentrated: three countries mine 75% of it, against 49% for copper.

Sources and years are listed at the end. Different publishers define data center demand differently. The "supply side" label is used for copper because the USGS reports production, not consumption, for the world.

No source publishes "uranium used by data centers", so this is a calculation with every input visible. Change an input and you change the answer.

This is a rough estimate of added fuel demand by 2035, worldwide, not only in the United States. It assumes the new reactors use as much fuel per gigawatt as today's fleet and that the whole 175 TWh is the nuclear addition, although the IEA gives no exact nuclear figure. It measures added demand, while the copper row measures total data center use, so the two are not a like-for-like ranking. The IEA expects the first small modular reactors only around 2030.

Prices only, without dividends or fees. The uranium line is the URA ETF, which holds uranium miners and nuclear-related companies, so it behaves partly like an equity fund and is not the uranium price. Do not read the two lines as the same kind of asset.

• The two numbers measure different things. Copper's under 2% is total data center use against refined output. Uranium's roughly 5% is our estimate of added fuel for new nuclear generation by 2035 against today's requirements. Both are low single digits, but they are not a like-for-like ranking, and copper is a far bigger market in tonnes and dollars.
• Uranium supply is more concentrated. Three countries mined 75% of it in 2024, and one, Kazakhstan, 39%. For copper the top three are 49%.
• The nuclear pipeline is real but slow. 81 reactors are under construction (88.3 GW), about 22% of the current fleet's 404 GW, while old plants are also retiring, so net capacity is not growing as fast as the pipeline suggests.
• Uranium demand is one use, copper has many. Reactor fuel is the only demand for uranium, so it moves with nuclear policy and plant restarts. Copper is spread over construction, electronics and transport, which softens the effect of any one sector.
• The price comparison is not like for like. Copper is a futures contract. Uranium here is an equity ETF. A strong ETF return can come from the stocks as well as from uranium, so use the table as context, not as proof of either metal's AI link.

For AI, copper is everywhere and small, uranium is narrow and harder to measure. Data centers need copper in every building and cable, but the IEA expects them to take under 2% of the copper market by 2030. Uranium only matters if nuclear supplies a meaningful part of data center power, and our estimate puts the added fuel for the IEA's nuclear additions by 2035 at about 5% of today's requirements, with big uncertainty about timing. That is a different measure from copper's total data center use, so the two are not a like-for-like ranking. Supply is the other half of the story: uranium comes from three countries, copper from a wider group, so the same demand news can move them differently. Neither is a pure AI bet, and the snapshot table shows how each has actually traded, which is history, not a forecast.

Does AI increase demand for uranium?

Modestly so far, and through electricity. The IEA expects natural gas to add 175 terawatt-hours of generation to meet data center demand by 2035 and nuclear to add about the same amount, notably in China, Japan and the United States. Taking 175 terawatt-hours as nuclear's addition, our estimate is roughly 22 gigawatts of extra reactors at a 90% capacity factor, which would need about 3,800 tonnes of uranium a year, about 5.5% on top of the 68,920 tonnes the world's reactors required in 2025. That is a derived estimate of added demand worldwide, not a published forecast, and it is not the same measure as the copper figure, which is total data center use. The first small modular reactors are not expected until around 2030.

Which matters more for AI infrastructure, copper or uranium?

They do different jobs. Copper is in the wiring, transformers and buildings of every data center, so its link to AI is broad but a small share of a very large market: the IEA expects data centers to use more than half a million tonnes a year by 2030, under 2% of refined copper output. Uranium fuels the reactors that may supply some of the power, so its link is narrower, and the extra fuel the IEA's nuclear additions would need is roughly 5% of today's requirements on our estimate. That is an added-demand estimate, not total data center use, so it is not directly comparable to the copper figure.

How much uranium does the world use each year?

The World Nuclear Association puts world uranium requirements at 68,920 tonnes of uranium in 2025, for 441 operable reactors with 404.127 gigawatts of capacity. Mines produced 60,213 tonnes in 2024, about 90% of demand, with the rest met from secondary supplies.

Who produces uranium?

Supply is concentrated. In 2024 Kazakhstan produced 23,270 tonnes, 39% of the world total, Canada 14,309 tonnes (24%) and Namibia 7,333 tonnes (12%), so three countries mined about 75% of the world's uranium. For copper the top three, Chile, Congo (Kinshasa) and Peru, were about 49% of 2025 output.

How can I track uranium on a chart?

There is no uranium spot price on the Global Markets Dashboard. This page uses the Global X Uranium ETF (URA) as a proxy. It holds uranium miners and nuclear-related companies, so it moves with equities as well as with uranium, and it is not the uranium price. Compare its returns with copper futures with that in mind.

How many nuclear reactors are being built?

As of 30 September 2026 the World Nuclear Association lists 441 operable reactors (404.127 gigawatts), 81 under construction (88.3 gigawatts) and 122 planned (111.1 gigawatts). The reactors under construction would add about 22% to today's capacity if all are completed, but new plants are largely being balanced by old ones retiring.
