AI Data Centers Drive Copper Demand; Three Stocks to Watch

Copper entered 2026 on strong footing, buoyed by demand from electric vehicles, renewable energy infrastructure, grid modernization, and a surging wave of AI data center construction. Today, data centers account for only 1% of global copper demand—but that share is poised to grow explosively. The reason is simple: an AI-powered data center requires 10 times more copper than a conventional facility, consuming it for electrical wiring, power grids, transformers, and transmission infrastructure that forms the backbone of the AI ecosystem.

The scale of investment underpinning this demand is staggering. The four major hyperscalers—the giant cloud providers driving most AI infrastructure buildout—raised their combined AI capital expenditure budget to $750 billion（約120兆円） for 2026. That figure is set to cross $1 trillion（約160兆円） in 2027 and continue climbing beyond. Research firm Moody's estimated that these four companies alone will invest more than $3 trillion（約480兆円） in AI data center capital over the next five years. Translated to copper demand, this represents a historic acceleration.

Against this backdrop, the article identifies three copper producers as investment candidates: Freeport-McMoRan Inc. (FCX), Southern Copper Corp. (SCCO), and BHP Group Ltd. (BHP). All three currently carry a Zacks Rank #3 (Hold). Freeport-McMoRan is conducting exploration activities near existing mines to expand reserves and is executing smelter projects in Indonesia; it also benefits from automotive electrification, as electric vehicles are copper-intensive. The company expects 9.5% revenue growth and 51.4% earnings growth for the current year; its Zacks Consensus Estimate for earnings improved 7.6% over the last 30 days. Southern Copper's case is built on industry-leading reserves, an expanding project pipeline, and favorable long-term copper demand. The company is advancing more than $20.5 billion（約3.3兆円） of investments across Peru and Mexico, creating what the article describes as a visible path to higher production over the next decade. Southern Copper expects 26.6% revenue growth and 46.6% earnings growth for the current year, with its earnings estimate improving 3.9% in the last 30 days. BHP Group remains a high-quality diversified miner with leadership in iron ore and growing exposure to copper and potash; it benefits from resilient iron ore volumes, strong execution at its Escondida and Copper South Australia operations, and progress on its Jansen potash project. BHP expects 12.6% revenue growth and 43.7% earnings growth for its current year ending June 2027, with earnings estimates improving 1.2% over the last 60 days.

Copper prices entered 2026 supported by multiple demand drivers—electric vehicles, renewable energy, grid modernization, and crucially, data center expansion. The article frames this moment as a potential inflection point: while data centers represent only 1% of current global copper demand, the infrastructure buildout required for AI could reshape the entire market. The four major hyperscalers (Amazon, Google, Meta, Microsoft—implied but not named in the body) are committing $750 billion（約120兆円） in 2026 alone, with spending expected to surpass $1 trillion（約160兆円） in 2027 and Moody's forecasting over $3 trillion（約480兆円） cumulatively through the next five years. This reflects the copper intensity of AI infrastructure—every hyperscale facility requires 10 times the copper wiring, transformers, and transmission equipment of a conventional data center.

The article's investment thesis rests on the gap between current and future demand: if AI deployment accelerates as projected, copper producers with proven reserves, expandable capacity, and execution track records stand to benefit materially. Southern Copper's $20.5 billion（約3.3兆円） pipeline across Peru and Mexico, Freeport-McMoRan's exploration activities and smelter projects in Indonesia, and BHP's diversified portfolio and potash/copper growth avenues each offer different angles on capturing this demand. The earnings growth rates cited (51.4% for FCX, 46.6% for SCCO, 43.7% for BHP) reflect analyst expectations that 2026 will be a strong year; however, all three carry a Zacks #3 (Hold) rating, suggesting the article frames them as watchlist candidates rather than strong buys.
