BHP has positioned copper as the primary driver of its long-term earnings, projecting that global demand for the metal will grow from approximately 34 million tonnes per year today to more than 50 million tonnes per year by 2050—a 47 percent increase the company said electrification, power-grid investment and AI-related infrastructure will push through.
Data center construction alone is expected to account for approximately 3 million tonnes of that additional demand, according to BHP's analysis. That figure reflects the copper intensity of AI infrastructure: each large-scale data center requires substantial copper wiring, cooling systems and power distribution hardware that simpler commercial buildings do not.
BHP is putting capital behind the forecast. The company is targeting 2.5 million tonnes per annum of copper equivalent production by fiscal year 2035, a significant increase from current output levels. That expansion plan makes BHP one of the few large-cap miners with a stated, dated production target tied directly to the electrification demand thesis.
On steel, BHP expects China to continue producing approximately 1 billion tonnes per annum through this decade. That projection matters for BHP's iron ore division, which remains a major revenue contributor even as copper gains ground. Iron ore feeds steelmaking, so sustained Chinese steel output at that scale provides a demand floor for the segment even as copper takes a larger share of the earnings mix.
The earnings composition at BHP is already shifting. Copper earnings overtaking iron ore in 2026 marks a structural change in how the company generates profit. Iron ore has been the traditional earnings engine for Australian diversified miners for most of the past two decades, driven by Chinese construction and infrastructure spending. The move toward copper as the lead earner reflects both rising copper prices and BHP's deliberate portfolio shift.
Net debt at BHP fell to approximately $9 billion from $14.7 billion in the first half of the fiscal year, according to recent production and financial data. That reduction gives the company balance sheet room to fund the copper expansion program without taking on excessive leverage—a meaningful distinction from smaller miners that must raise equity or debt to grow output.
Fiscal year 2027 guidance from BHP shows modest iron ore growth alongside lower copper output in the near term before the longer expansion ramp takes hold. That near-term dip in copper production is a timing issue tied to mine sequencing, not a reversal of the strategic direction. The FY35 target of 2.5 million tonnes per annum copper equivalent remains the stated destination.
On the supply side, copper faces structural constraints that support BHP's pricing assumptions. New mine development cycles run 15 to 20 years from discovery to production, and the pipeline of large undeveloped copper deposits is thin relative to the demand growth BHP projects. Tight supply combined with growing electrification demand has already pushed copper prices to record levels in 2026, with copper futures reaching all-time highs driven by supply disruptions and power-grid investment rather than broad global economic growth.
Rio Tinto, BHP's closest large-cap peer in copper exposure, has seen its shares rise 49.9 percent driven by strong revenue and profitability growth across its aluminum, lithium and copper segments. That move illustrates how equity markets are pricing in the structural copper narrative, though mining equities as a group have underperformed the physical metal year-to-date. The Global X Copper Miners ETF (COPX) fell 23.1 percent from its 2026 high even as copper futures held near peak levels—a gap of 9.5 percentage points between the equities and the metal itself.
That divergence between physical copper prices and mining equity performance creates an operational leverage argument for BHP specifically. BHP's production scale, balance sheet strength and FY35 expansion target put it in a different risk category than smaller miners whose underperformance drove the COPX drawdown. Analysts have issued buy calls on BHP shares citing copper growth as the primary catalyst, though current valuations are seen as limiting near-term upside for investors entering at today's levels.
BHP shares trade on both the Australian Securities Exchange and the New York Stock Exchange as an ADR under the ticker BHP. The stock sits at the intersection of two demand themes—AI infrastructure build-out and global electrification—that are drawing capital from investors who previously had no reason to look at diversified mining companies. The FY35 production target gives those investors a specific, dated milestone to anchor a long-term thesis against.
