The short answer: EVs, by a wide margin on the latest numbers. The 20 million electric cars sold in 2025 carry about 1.2 to 1.7 million tonnes of copper (4% to 6% of refined output), against more than 0.5 million tonnes a year for data centers by 2030 (under 2%). One hyperscale AI data center can hold up to 50,000 tonnes, the copper of about 600,000 electric cars.

The numbers
| Metric | Electric vehicles | AI data centers |
|---|---|---|
| Copper per unit | 83 kg per battery car, 60 kg per plug-in hybrid, against 23 kg for a gasoline or diesel car (2017 research) | Up to 50,000 tonnes per hyperscale AI facility |
| Volume | More than 20 million electric cars sold in 2025 (+20%), about 25% of new cars; about 23 million expected in 2026 | Data center electricity use 415 TWh in 2024, expected to roughly double by 2030 |
| Copper a year | About 1.2 to 1.7 million tonnes in the cars sold in 2025 (our calculation) | More than 0.5 million tonnes a year by 2030 (IEA) |
| Share of refined copper (29 Mt) | About 4% to 6% | Under 2% |
| That much copper at the latest price | $18 billion to $24 billion | $7 billion |
| Charging and connection | Each charger adds 0.7 kg of copper, a fast charger up to 8 kg | Power distribution and cooling inside the facility, plus grid connection |
| Growth signal | +20% sales in 2025 | Data center electricity growing about 15% a year to 2030 |
| Main caveat | Per-car figures are from 2017 and designs have changed | Estimates vary widely with design and cooling |
Sources and years are listed at the end. The EV total multiplies the IEA's 20 million cars by the International Copper Association's 60 kg (plug-in hybrid) and 83 kg (battery) figures; the real mix of the two falls between those bounds. The data center figure is for 2030, so the years differ.
Per car and per year
$10,000 invested five years ago
$10,000 invested five years ago would be worth: Copper: $15,222. Price changes only, without dividends or fees.
Copper futures only, prices without fees. Copper is demanded by both stories and by construction, power grids and electronics, so its price is not a measure of either one.
What the numbers tell us
- EVs are the larger copper user on the latest numbers. About 4% to 6% of refined copper for the cars sold in 2025, against under 2% for data centers by 2030.
- One AI data center is a very large single customer. Up to 50,000 tonnes in one facility equals the copper in about 600,000 battery cars, which is why a few announcements can move the conversation.
- The growth rates look different. EV sales grew 20% in 2025. Data center electricity use is expected to grow about 15% a year to 2030, from a much smaller copper base.
- The comparison is not like for like. Cars are sold in units and carry their copper with them. Data centers are built capacity and their copper is installed once. One is a 2025 estimate, the other a 2030 outlook.
- Old per-car numbers matter. The 83 kg and 60 kg figures date from 2017. If current designs use less copper per car, the EV total here is a little high; if they use more, it is low.
Bottom line
EVs need more copper than AI, and will for the rest of this decade on the published numbers. The 20 million electric cars sold in 2025 carry roughly 1.2 to 1.7 million tonnes, against more than half a million tonnes a year expected for data centers by 2030. AI is the faster-growing and more concentrated story: one hyperscale facility can hold the copper of about 600,000 cars. Neither is a small number, but neither is most of the copper market either, which still leans on construction and power grids. Treat any headline that one "needs" more than the other as a question of which year and which estimate it uses.

Common questions
How much copper is in an electric car?
The International Copper Association's 2017 research puts a battery electric car at about 83 kilograms of copper, a plug-in hybrid at 60, a hybrid at 40 and a gasoline or diesel car at 23. Designs have changed since then and estimates differ by source and year, but electric cars consistently use two to four times as much copper as a conventional car.
Do EVs or AI data centers need more copper?
EVs, on current numbers. The IEA reports more than 20 million electric cars sold in 2025. At 60 to 83 kilograms each, the copper in those cars is about 1.2 to 1.7 million tonnes, roughly 4% to 6% of the 29 million tonnes of refined copper the world produces. The IEA expects data centers to use more than half a million tonnes a year by 2030, under 2%. The years differ, and data center demand is growing fast.
How much copper does one AI data center use?
The Copper Development Association estimates up to 50,000 tonnes for a single hyperscale AI data center, as reported by US Global Investors. At 83 kilograms per battery electric car, that is the copper in about 600,000 cars. The figure depends heavily on design and cooling, so treat it as an upper estimate.
How many electric cars are sold each year?
The IEA's Global EV Outlook 2026 reports that electric car sales grew 20% to more than 20 million in 2025, about one in four new cars sold worldwide. It expects about 23 million in 2026. Electric cars in the IEA's count include both battery electric and plug-in hybrid models.
Will AI overtake EVs as a source of copper demand?
Not by 2030 on these numbers. EVs already account for roughly 1.2 to 1.7 million tonnes a year and are still growing, while the IEA expects data centers at more than half a million tonnes by 2030. AI is the faster-growing story in relative terms, but from a much smaller base. Many forecasts differ, so this is a comparison of published estimates, not a forecast.
