Copper Surges Past $6.60/lb as AI Datacenters and Grid Demand Squeeze Supply

Copper hit US$6.6070 per pound on October 27, 2026 — a 1.52% single-session gain that pushed the metal to C$9.27/lb at the prevailing USD/CAD rate of 1.4028. The move reflects a tightening market where demand from two of the world’s most capital-intensive buildouts — AI datacenters and renewable energy grids — is running headlong into constrained mine supply. Teck Resources (TSX: TECK.B) rose 2.14% to $84.45, outperforming the broader materials sector and signalling that Canadian copper producers are capturing the upside.

AI Datacenters: The Demand Driver Nobody Saw Coming

Hyperscale datacenters powering the global AI boom have quietly become one of the fastest-growing sources of copper demand. A single large-scale datacenter requires between 15 and 30 tonnes of copper for power distribution, cooling systems, and server interconnects — and hundreds of such facilities are under construction or in permitting across North America, Europe, and Southeast Asia. The International Copper Association estimates AI and cloud infrastructure could account for an incremental 1 million tonnes of annual copper demand by 2030. That number is roughly equivalent to the entire annual output of Chile’s Escondida mine, the world’s largest copper operation.

This demand layer compounds already-robust consumption from EV motor production and utility-scale grid expansion. A single electric vehicle uses roughly 83 kilograms of copper — four times the amount in a conventional internal combustion vehicle. Canada’s own grid hardening program, accelerated under federal clean-electricity regulations, is expected to require billions of dollars in copper wiring and transformer upgrades through 2035.

Chile and Peru Supply Disruptions Add Pressure

On the supply side, the picture is increasingly strained. Chile’s Codelco, the world’s largest state-owned copper producer, has flagged continued grade decline across its legacy open-pit operations, with average ore grades falling below 0.7% copper — less than half the grade of the same deposits a decade ago. Meanwhile, labour tensions at several Peruvian concentrates have reignited strike risk heading into the Southern Hemisphere summer, historically a period of elevated supply disruption. Analysts at Wood Mackenzie now project a copper market deficit of approximately 500,000 tonnes in 2026, widening to over 800,000 tonnes by 2028 absent major new project approvals.

New project timelines offer little near-term relief. From discovery to first production, a greenfield copper mine averages 16 years of development — meaning projects sanctioned today will not materially affect supply until the early 2040s.

Teck Resources: Canada’s Copper Flagship

Teck Resources is the most direct Canadian equity expression of the copper bull thesis. Following its transformative divestiture of the steelmaking coal business in 2024, Teck is now a focused copper and zinc producer, with its QB2 operation in Chile ramping toward a 300,000-tonne annual copper equivalent run rate. At today’s copper price of US$6.6070/lb, QB2’s economics are highly attractive — the operation carries an all-in sustaining cost estimated below US$2.00/lb. Teck’s 2.14% gain to $84.45 today reflects the market pricing in that operating leverage.

For Canadian retail investors, the copper story is no longer a slow-burn commodity cycle. It is a structural convergence of electrification, digitization, and mine supply inertia — playing out in real time on the TSX. With Teck providing direct exposure and junior developers on the TSX-V watching their project valuations climb, copper’s October momentum may have significant room to run.
