Copper Surges as Shifting Trade Policy and AI Demand Collide

Key Points

• Copper prices hit record highs above $6.72 per pound, driven by Section 232 tariffs on copper products and surging AI-related data center demand.
• Freeport-McMoRan, Southern Copper, and BHP have all posted strong share price gains and earnings growth as direct or diversified plays on the copper rally.
• Some analysts warn that a portion of copper's price surge reflects a temporary tariff-driven policy premium that could fade once trade rules are finalized.

Investors looking to capitalize on the artificial intelligence infrastructure boom have increasingly turned to basic materials, and industrial metals—copper chief among them—are having a moment few saw coming even a year ago. What started as a trade-policy story has fused with a structural demand story, and the combination is rewriting price records almost weekly.

Copper Prices Rise on Tariffs and AI Infrastructure Demand

Comex copper touched a fresh all-time high above $6.72 per pound in late August, and the metal has continued to trade near those levels into September. Two forces are doing the heavy lifting.

First, there's the current tariff policy. Washington imposed a 50% Section 232 tariff on semi-finished copper products and copper-intensive derivatives in 2025, later expanding the rate structure in April 2026, while leaving refined cathode largely exempt—for now.

That exemption has been enough to trigger a scramble. Traders have spent months rerouting metal into U.S. warehouses ahead of the possibility that refined copper will eventually be swept into the tariff policy, and Comex inventories have ballooned to levels that would have seemed unthinkable two years ago.

The catch is that once copper lands in a bonded U.S. warehouse, it's largely stuck there. So what was supposed to be a comfortable global surplus has effectively been drained from the rest of the world. Analysts at CRU, who had projected a healthy 2026 surplus, now describe the non-U.S. market as balanced at best, with some warning it could look like an outright deficit if the flows continue.

Second, and less reversible, is demand. Data centers have become a source of copper demand that doesn't flex with price the way industrial buying usually does. Hyperscalers need the wiring, bus bars, and cooling infrastructure regardless of what copper costs per pound.

That's a new kind of buyer for a market that used to take its cues almost entirely from construction and manufacturing cycles. Layer on grid modernization and electrification, and you have a demand base that's structurally higher even before the tariff-driven stockpiling is factored in.

Freeport-McMoRan Offers Direct Exposure to Rising Copper Prices

Freeport-McMoRan NYSE: FCX is the most direct U.S.-listed proxy for copper prices and the largest domestic producer of refined copper. That means it stands to benefit most if the exemption narrows.

The FCX chart confirms that story. Shares have run from the low $40s a year ago to the mid-$70s, with the 50-day moving average now trending firmly upward and MACD back in bullish territory after a rocky spring.

Q2 2026 net income attributable to common stock came in at $984 million, or 68 cents per share. That pushed first-half net income up 65% year-over-year, even as headline revenue slipped to $7.03 billion from $7.58 billion a year earlier. That decline was driven by lower Indonesian gold and copper volumes during the phased Grasberg Block Cave ramp-up, not by weaker pricing.

Realized copper prices averaged $6.17 per pound in the quarter, and U.S. mining operations more than doubled their operating income contribution versus the first half of 2025, underscoring just how much of FCX's earnings power is now coming from the domestic side of the business, which the tariff regime is designed to protect.

Southern Copper Combines Low Costs With Copper Price Leverage

Southern Copper NYSE: SCCO is the low-cost operator of the group, and its Q2 2026 numbers underline why. Revenue rose roughly 41% year-over-year to $4.29 billion, while net income jumped more than 70% to $1.67 billion.

Byproduct credits from silver, molybdenum, and zinc have been the real story. They pushed operating cash cost per pound of copper down to just a nickel, from 63 cents a year earlier. That's a cost structure in which margin expansion accelerates disproportionately as copper prices climb, since so little of the cost base remains exposed once byproducts are netted out.

The chart shows that investors understand the benefits of the company's operating leverage. SCCO has more than doubled off its spring lows and set a fresh record above $220 in late August before pulling back slightly.

BHP Gives Investors Diversified Exposure to the Copper Boom

BHP Group NYSE: BHP is the diversified pick, and for readers who are less risk-tolerant, it's arguably the easiest entry point into the copper thesis.

For the first time in the company's history, copper generated more than half of BHP's underlying EBITDA in fiscal 2026, about 54%, or roughly $18 billion, overtaking iron ore as the group's largest earnings contributor.

Underlying attributable profit rose 30% to $13.2 billion for the year. BHP's chart shows the same steady uptrend as its pure-play peers, climbing from the high $50s a year ago to near $96, though it's pulled back modestly from its late-August peak alongside the rest of the group. The tradeoff for investors is that while BHP is less tethered specifically to copper, it means it has a lower concentration risk than the other names on this list.

Copper’s Rally Faces a Risk From Tariffs and Policy Uncertainty

Not everyone treats $6.70 copper as a clean read on global growth. Some analysts note the price carries a real "policy premium" tied to tariff uncertainty and the rush to beat any rule change, rather than reflecting pure consumption strength.

Glencore's CEO has even argued that a final tariff decision, whichever way it goes, could take some of the heat out of prices simply by ending the uncertainty. The fundamentals (AI-driven demand, mine supply constraints, grid buildout) are real and durable, but part of today's price also reflects a timing trade that could unwind once the tariff picture clarifies.
